[0006] Over the past few decades, the continuous exploration of nanomedicine has made great contributions to cancer treatment. Carrier-assisted nanomedicines and carrier-free nanomedicines are being developed to improve drug intrinsic kinetics and safety. However, there are some limitations to these nanotherapeutic approaches. First, the complexity and toxicity caused by their multi-component nature have seriously hindered the clinical transformation of many nanoformulations. Second, most of the drugs used for conventional delivery studies were approved decades ago, and some are no longer first-line therapeutic drugs. Third, nanoformulations designed for recently developed therapeutic agents (especially new chemical entities) may encounter patent issues. Finally, not all drugs can be structurally modified. These limitations can be addressed in the context of medicinal chemistry. Compared with nanomedicine, which focuses on the development of drug delivery properties, medicinal chemistry is committed to discovering drug entities at an early stage. Although drug discovery technology has produced many drug leads and candidates, issues surrounding pharmacokinetics, metabolism and toxicology remain challenging. These challenges can also be relatively easily addressed by nanotechnology in the field of nanomedicine. In order to take advantage of this interdisciplinary connection, the principles of nanotechnology are integrated into initial drug design, and a single-component non-prodrug nanomedicine (ONN) strategy ( Figure 1 ). In this strategy, drug design follows both conventional drug design strategies and the principle of molecular self-assembly, so that the designed drugs have advantages from the perspectives of drug discovery and drug delivery.
[0007] Lysosomes are selected as targets for cancer therapy. Cancer cell lysosomes are enlarged, easily ruptured, and more fragile than normal lysosomes. Lysosomal membrane permeabilization (LMP) can directly trigger cell death by enabling proteolytic enzymes (i.e., cathepsins) to be released into the cytoplasm; therefore, lysosomal detergents that can induce LMP have been developed for tumor therapy. In addition, lysosomal inhibition has considerable potential as an anticancer strategy because it interferes with autophagy, which is an important pathway for the stress response and drug resistance of established tumors. The lysosomal alkalinizing agents chloroquine (CQ) and hydroxychloroquine (HCQ) are commonly used autophagy inhibitors that have been tested in multiple clinical trials for various cancer types. However, their efficacy is considered insufficient, especially when they are used as a single agent.
[0008] A series of lipophilic cationic BAQ derivatives ( Figure 1 and Figure 7). BAQ12 and BAQ13 were chosen to construct ONNs because of their potential as therapeutic agents and self-assembling building blocks. These BAQ ONNs showed excellent anticancer activity in vitro, with enhanced effects on lysosomal disruption, lysosomal dysfunction, and autophagy inhibition. In addition, as nanomedicines, BAQ ONNs exhibited expected self-delivery properties. From both drug discovery and drug delivery perspectives, these advantages ultimately contribute to the significant anticancer activity of these compounds as single agents in in vivo gastrointestinal cancer models. In addition, BAQ ONNs show promise for use in combination therapy with nabuccal, as they play a dual role as a therapeutic agent and a delivery vehicle. With its multidisciplinary integration and ingenious functional superposition, BAQ ONNs will become a good alternative for improving cancer treatment.
[0009] The integration of unique advantages in the field of drug discovery and drug delivery is very valuable for the progress of drug development. This paper describes a self-delivered single-component new chemical entity nanomedicine (ONN) strategy to improve cancer treatment by incorporating self-assembly principles into drug design. Lysosomal detergents (MSDH) and autophagy inhibitors (Lys05) are hybridized to develop bisaminoquinoline derivatives that can inherently form nanoassemblies. The selected BAQ12 and BAQ13 ONNs are very effective in inducing lysosomal destruction, lysosomal dysfunction and autophagy blocking, and show 30 times higher antiproliferative activity than hydroxychloroquine used in clinical trials. These single drug nanoparticles show excellent pharmacokinetic and toxicological properties and significant anti-tumor efficacy in vivo. In addition, they can encapsulate additional drugs and deliver them to the tumor site, and are therefore promising agents for combined therapies based on autophagy inhibition. Considering their interdisciplinary advantages, these BAQ ONNs have great potential for improving cancer treatment. What is needed is a new BAQ ONN. Surprisingly, the present invention meets this demand and other needs. Summary of the invention

Oral formulations include tablets, pills, powders, dragees, capsules, liquids, lozenges, cachets, gels, syrups, slurries, suspensions, etc., suitable for ingestion by patients. The compositions of the present invention can also be administered by injection, i.e., intravenous, intramuscular, intradermal, subcutaneous, intraduodenal or intraperitoneal injection. In addition, the compositions described herein can be administered by inhalation, such as intranasal administration. In addition, the compositions of the present invention can be administered transdermally. The compositions of the present invention can also be administered via intraocular, intravaginal and intrarectal routes, including suppositories, insufflations, powders and aerosol formulations (e.g., steroid inhalers, see Rohatagi, J. Clin. Pharmacol., Vol. 35: 1187-1193, 1995; Tjwa, Ann. Allergy Asthma Immunol., Vol. 75: 107-111, 1995). Therefore, the present invention also provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier or excipient and a compound of the present invention.
[0152] In order to prepare pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers may be solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier may be one or more substances, which may also be used as diluents, flavoring agents, binders, preservatives, tablet disintegrants, or encapsulating materials. Details on formulation and administration techniques are described in detail in the scientific and patent literature, see, for example, the latest edition of Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pennsylvania ("Remington's").
[0153] In powders, the carrier is a finely divided solid which is mixed with the finely divided active ingredient. In tablets, the active ingredient is mixed with a carrier having the necessary binding properties in suitable proportions and compressed into the desired shape and size. Powders and tablets preferably contain from 5% or 10% to 70% of the compound of the invention.
[0154] Suitable solid excipients include, but are not limited to, magnesium carbonate, magnesium stearate; talc; pectin; dextrin; starch; tragacanth; low melting wax; cocoa butter; carbohydrates; sugars, including but not limited to lactose, sucrose, mannitol or sorbitol, starch from corn, wheat, rice, potato or other plants; cellulose, such as methylcellulose, hydroxypropyl methylcellulose or sodium carboxymethylcellulose; and gums, including gum arabic and tragacanth; and proteins, including but not limited to gelatin and collagen. If desired, disintegrators or solubilizers may be added, such as cross-linked polyvinyl pyrrolidone, agar, alginic acid or a salt thereof such as sodium alginate.
[0155] The dragee cores are provided with a suitable coating, such as a concentrated sugar solution, which may also contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol and / or titanium dioxide, lacquer solutions and suitable organic solvents or solvent mixtures. Dyes or pigments may be added to the tablet or dragee coating for product identification or to characterize the amount (i.e., dosage) of the active compound. The pharmaceutical preparations of the invention may also be used orally, for example using push-fit capsules made of gelatin, and sealed soft capsules made of gelatin and a coating such as glycerol or sorbitol. Push-fit capsules may contain the compound of the invention mixed with a filler or binder such as lactose or starch, a lubricant such as talc or magnesium stearate, and optionally a stabilizer. In the soft capsule, the compound of the invention may be dissolved or suspended in a suitable liquid, such as a fatty oil, liquid paraffin, or a liquid polyethylene glycol with or without a stabilizer.
[0156] To prepare suppositories, a low melting point wax such as a mixture of fatty acid glycerides or cocoa butter is first melted and the compound of the present invention is uniformly dispersed therein by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool, and thereby solidified.
[0157] Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water / propylene glycol solutions. For parenteral injection, liquid preparations may be formulated in solution in aqueous polyethylene glycol solution.
[0158] By dissolving the compound of the present invention in water and adding suitable colorants, flavoring agents, stabilizers and thickeners as needed, an aqueous solution suitable for oral use can be prepared. Aqueous suspensions suitable for oral use can be prepared by dispersing the finely divided active component in water containing a viscous substance and a dispersant or wetting agent, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, hydroxypropyl methylcellulose, sodium alginate, polyvinyl pyrrolidone, tragacanth and gum arabic, and the dispersant or wetting agent is such as naturally occurring phosphatides (e.g., lecithin), condensation products of alkylene oxides with fatty acids (e.g., polyoxyethylene stearate), condensation products of ethylene oxide with long-chain fatty alcohols (e.g., 17-ethyleneoxycetanol), condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol (e.g., polyoxyethylene sorbitol monooleate), or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides (e.g., polyoxyethylene sorbitan monooleate). The aqueous suspension may also contain one or more preservatives, such as ethyl or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose, aspartame, or saccharin. The formulation may be adjusted for osmolarity.
[0159] Also included are preparations in solid form that are converted into preparations in liquid form for oral administration shortly before use. Such liquid forms include solutions, suspensions, and emulsions. In addition to the active ingredient, these preparations may contain coloring agents, flavoring agents, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, etc.
[0160] Oily suspensions can be prepared by suspending the compound of the present invention in a vegetable oil (such as peanut oil, olive oil, sesame oil or coconut oil), or in a mineral oil (such as liquid paraffin), or in a mixture thereof. Oily suspensions may contain thickeners such as beeswax, hard paraffin or cetyl alcohol. Sweeteners may be added to provide a palatable oral preparation, such as glycerol, sorbitol or sucrose. These preparations can be preserved by adding antioxidants (such as ascorbic acid). As an example of an injectable oil solvent, see Minto, Journal of Pharmacology and Experimental Therapeutics (J.Pharmacol.Exp.Ther.), Vol. 281: pp. 93-102, 1997. The pharmaceutical preparations of the present invention may also be in the form of an oil-in-water emulsion. The oil phase may be a vegetable oil or a mineral oil as described above, or a mixture of these. Suitable emulsifiers include naturally occurring gums such as gum arabic and gum tragacanth; naturally occurring phospholipids such as soy lecithin; esters or partial esters derived from fatty acids and hexitol anhydrides such as sorbitan monooleate; and condensation products of these partial esters with ethylene oxide such as polyoxyethylene sorbitan monooleate. Emulsions may also contain sweeteners and flavorings, such as in the preparation of syrups and elixirs. Such preparations may also contain a demulcent, a preservative, or a coloring agent.
[0161] In another embodiment, the composition of the present invention can be formulated for parenteral administration, such as intravenous (IV) administration or administration into a body cavity or organ lumen. The preparation for administration will generally include a solution of the composition of the present invention dissolved in a pharmaceutically acceptable carrier. Acceptable solvents and solvents that can be used are water and Ringer's solution (an isotonic sodium chloride). In addition, sterile fixed oils can generally be used as solvents or suspension media. For this purpose, any mild fixed oil can be used, including synthetic monoglycerides or diglycerides. In addition, fatty acids such as oleic acid can also be used to prepare injections. These solutions are sterile and generally do not contain undesirable substances. These preparations can be sterilized by conventional, well-known sterilization techniques. The preparation can contain pharmaceutically acceptable auxiliary substances required for close physiological conditions, such as pH regulators and buffers, toxicity regulators, such as sodium acetate, sodium chloride, potassium chloride, calcium chloride, sodium lactate, etc. The concentration of the composition of the present invention in these preparations can vary widely, and will be mainly based on fluid volume, viscosity, body weight, etc. and selected according to the needs of the selected specific mode of administration and the patient. For IV administration, the preparation can be a sterile injectable preparation, such as a sterile injectable aqueous or oily suspension. The suspension can be formulated according to known techniques using those suitable dispersants or wetting agents and suspending agents. The sterile injectable preparation can also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent, such as a solution in 1,3-butanediol.
[0162] The compositions of the present invention can be delivered by any suitable means, including oral, parenteral and topical methods. Transdermal administration methods by topical routes can be formulated into applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, gels, paints, powders and aerosols.
[0163] The pharmaceutical formulation is preferably in unit dosage form. In this form, the formulation is subdivided into unit doses containing appropriate quantities of the compound of the invention. The unit dosage form can be a packaged formulation containing discrete quantities of the formulation, such as packaged tablets, capsules, and powders in vials or ampoules. Additionally, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these packaged forms.

[0239] Example 2: Nanocarriers
[0240] Preparation and characterization of BAQ ONN. NPs were prepared by reprecipitation. A methanol solution of BAQ derivative was added dropwise to MilliQ water while stirring for 5 min (volume ratio, 1:10), and then uniform NPs were obtained after rotary evaporation (40 °C, 20 min), which were subsequently characterized by Zetasizer Nano ZS (Malvern Instruments). TEM samples were prepared by dropping 0.5 mM NPs on a carbon square mesh and dried naturally, and then observed under a Talos L120C TEM (FEI) at an accelerating voltage of 80 kV. In order to determine the drug content in the nanoformulation, the prepared drug-loaded NPs were cut off by a centrifugal filter (ultracel-10 kDa, Mil lipore), and the absorbance of the filtrate (diluted with DMSO, 1:10, volume ratio) was measured to calculate the drug concentration.
[0241] Discovery of BAQ derivatives as potential ONNs. BAQ12-BAQ18 were designed by hybridizing the key structural elements of the lysosomal autophagy inhibitor Lys05 and the lysosomal detergent MSDH to achieve pharmacological fusion ( Figure 1 Based on the principle of self-assembly, it is envisioned that the inclusion of a long hydrophobic tail with a cationic BAQ head would drive them to form nanoparticles (NPs). Since the calculated pKa of the BAQ head is 8.4, this self-assembly should be dependent on the pH of the environment, with NPs forming under neutral conditions and dissociating into free building blocks after protonation in an acidic environment.
[0242] Compounds (BAQ12-BAQ18) were synthesized and 1 H NMR spectrum, 13 C NMR and HRMS spectra confirmed the structure ( Figure 7 ). In contrast to Lys05 and MSDH, BAQ12-BAQ18 are not completely soluble in water either as free base or hydrochloride salt. However, the lipophilic cations allow spontaneous self-assembly in water via nanoprecipitation, resulting in a homogeneous milky white NP solution. The assembled NPs of BAQ12-BAQ18 have similar nanoscale features, including their size (100 nm-140 nm), polydispersity index (PDI) values less than 0.1, and positive surface charge (approximately +40 mV) (Table 1 and Fig. 8A The pH-responsive dissociation behavior was then evaluated by monitoring the size changes of the particles ( Figure 2A). All BAQ NPs are intact under near-neutral conditions and dissociate only under relatively acidic conditions. The critical dissociation pH of BAQ12-BAQ14 is 5.5-6.0, and the critical dissociation pH of BAQ15-BAQ18 is 5.0-5.5. When protonated in an acidic environment, the BAQ12-BAQ18 lipophilic cations become amphiphilic molecules and acquire surface activity. The hemolysis test was then used to evaluate the pH-responsive biofilm disruption ability of the compounds. Under near-neutral conditions (pH ≥ 6.5), none of the NPs had a hemolytic effect, but when the pH was below 6.0, the NPs began to induce hemolysis ( Figure 2B and Figure 8B ). Among these compounds, BAQ12 NP and BAQ13 NP exhibited the strongest hemolytic activity, inducing up to 90% hemolysis under simulated lysosomal conditions (pH 4.0-5.5); in contrast, BAQ14 NP induced moderate hemolysis (70%), and BAQ15-BAQ18 NP produced only about 50% hemolysis. In the control group, the conventional lysosomal detergent MSDH showed only a weak hemolytic response to pH, and Lys05, which has no detergent ability, did not cause observable hemolysis at the same concentration and over the entire pH range. Because LMP is a potential stimulator of apoptosis, BAQ12 and BAQ13, whose detergents can be activated in lysosomes, may directly and effectively induce cancer cell death. In addition, after titration with hydrochloric acid (HCl), BAQ12 NP and BAQ13 NP showed a clear pH plateau in a narrow pH range (at about pH 6.0), indicating their strong pH buffering capacity ( Figure 2C ). In contrast, the pH values of the other NPs (BAQ14-BAQ18) decreased proportionally, and only a brief pH plateau was observed for Lys05 (pH 7.2) and MSDH (pH 6.2). Since lysosomal degradation requires sufficient acidification, BAQ12 and BAQ13 were preferred due to their strong H + buffering capacity, showing a greater potential than other compounds to induce lysosomal dysfunction and thus potentially impair tumor cell growth.
[0243] Table 1: Nanoparticle characterization of BAQ derivatives and IC50 values against cancer cells.
[0244]
[0245] To validate the therapeutic efficacy of BAQ12-BAQ18, a preliminary screening was performed on various cancer cell lines using the MTS assay. Within 24 h of treatment, these derivatives exhibited varying degrees of antiproliferative effects. BAQ12 and BAQ13 were highly potent and showed approximately 3-fold, 20-fold, and 10-fold greater potency than Lys05, HCQ, and MSDH, respectively, but the activity steadily decreased as the hydrophobic tail was extended from 14 to 18 carbons (Table 1 and Figure 8C ). This decrease is due to the detergency of the compound and the H + Based on the above results, BAQ12 and BAQ13 were then selected as representatives for constructing BAQ ONNs in subsequent studies.
[0246] pH-responsive assembly and high drug loading efficiency. The pH-responsive assembly-dissociation phase transition of BAQ ONNs was then determined by transmission electron microscopy (TEM). At pH 7.4, the NPs exhibited a strong Tyndall effect and displayed a liposome-like nanostructure with a diameter of approximately 100 nm and a bilayer thickness of approximately 5 nm ( Figure 2D ). These results are consistent with dynamic light scattering (DLS) measurements. In contrast, at pH 5.0, the solution loses its Tyndall effect and no vesicles are present under TEM, demonstrating that the NPs are dissociated under this condition ( Figure 2E Then, the release behavior of BAQ ONN at physiological pH (7.4) and lysosomal pH (5.0) was studied. Figure 2F As shown, BAQ12 NP and BAQ13 NP released almost completely (about 90%) within 8 h at pH 5.0, but only about 10% of the agent was released within 24 h under neutral conditions. Considering that lysosomes maintain the pH in the range of 4.0-5.5, it is believed that BAQ ONNs dissociate into free small molecules upon reaching these compartments, thereby exerting their therapeutic effects. The critical aggregation concentration (CAC) of BAQ12NP and BAQ13 NP was measured to be 0.76 μM and 0.25 μM, respectively ( Figure 2G The 3-fold difference observed between them suggests that BAQ13 can form NPs more easily than BAQ12, despite the difference of only one methylene unit between their molecular structures. Both NPs exhibited good particle size stability at room temperature for a relatively long duration, even in the presence of 10% serum or 0.5 mM bovine serum albumin ( 9A to 9F ). Moreover, BAQ13 NPs showed higher stability than BAQ12 NPs in this long-term storage, which may be due to their different CAC.
[0247] The next study was whether the liposome-like BAQ ONNs could encapsulate additional pharmaceutical agents. After nanoprecipitation of BAQ13 and various pharmaceutical agents, uniform NPs with a unimodal size distribution were spontaneously formed (Table 2 and Figure 9G BAQ13 NPs exhibited high drug loading (up to 50%, by mass) and drug encapsulation efficiency of approximately 90% (Table 2), suggesting that BAQ13 NPs can exceed the drug loading limits of conventional liposome-based and polymer-based drug delivery systems. It is very encouraging that these simple NPs composed of a single small molecule therapeutic entity exhibit such a strong drug loading capacity.

[0250] Accumulation in lysosomes and lysosomal destruction. To confirm the lysosomal accumulation of BAQ ONNs, the near-infrared fluorescent dye 1,1'-dioctadecyl-3,3,3',3'-tetramethylindoldi-carbocyanine (DiD) was loaded for labeling and tracking. As expected, lysosomal spots (green) in MIA PaCa-2 cells stained with dextran-Alexa Fluor 488 (AF488) consistently overlapped with DiD-labeled NPs (red), indicating that BAQ ONNs were rapidly taken up by cells and accumulated in lysosomes ( Figure 3A and Fig. 10A After this accumulation, BAQ ONNs reduced LysoTracker-positive spots, showing their ability to deacidify lysosomes similar to Lys05 and MSDH ( Figure 3B and FIG. 10B to FIG. 10C ).
[0251] The induction of LMP by BAQ12 and BAQ13 was investigated by live cell staining with the dye acridine orange (AO). Compared with cells treated with Lys05 and MSDH, cells treated with BAQ12 NP or BAQ13 NP showed a reduced number of red spots and an increased ratio of green fluorescence to red fluorescence, indicating that BAQ ONN has an increased ability to induce lysosomal disruption in cancer cells. Figure 3C and FIG. 10D to FIG. 10E The LMP effect was further confirmed by detecting the release of dextran-AF488 from lysosomes. Figure 3D As shown, treatment with BAQ ONNs resulted in a diffuse staining pattern throughout the cytoplasm, indicative of lysosomal leakage, whereas fluorescence in control cells appeared confined to punctate structures, representing intact lysosomes. Using their LMP function, BAQ ONNs were shown to induce the release of cathepsin B from isolated lysosomes, an important trigger of apoptosis ( Figure 3ESince no LMP was observed in MSDH-treated cells, the results suggest that BAQ12 and BAQ13 represent the next generation of lysosomal detergents.
[0252] Autophagy inhibition. To explore the effects of BAQ ONN on autophagy, the levels of microtubule-associated protein 1 light chain 3 (LC3) and Sequestosome 1 (SQSTM1) / p62 proteins, which are commonly used to monitor changes during autophagy, were measured. During autophagy, the cytosolic form of LC3 (LC3-I) is converted into a lipid-modified form (LC3-II), which is then recruited to the autophagosome membrane. At the same time, the autophagic substrate SQSTM1 / p62 protein is degraded by selective incorporation into autophagosomes. Therefore, when autophagy is inhibited, increased levels of LC3-II and SQSTM1 / p62 should be observed, while if autophagy is activated, increased levels of LC3-II and decreased levels of SQSTM1 / p62 should be observed. Figure 3F to Figure 3G As shown, MIA PaCa-2 cells treated with BAQ ONN showed significant concentration-dependent increases in both LC3B-II and SQSTM1 / p62 protein levels compared to untreated cells and cells treated with Lys05. This increase was also observed after treatment with bafilomycin A1 (BfA1), a known autophagy inhibitor. These findings suggest that BAQ ONN can inhibit cellular autophagy more effectively than Lys05.
[0253] The autophagy inhibition was then confirmed by imaging with LC3B-GFP, as the formation of fluorescent LC3-II puncta in cells can be used to visualize the accumulation of autophagosomes. Cells treated with BAQ ONNs generated distinct LC3B-GFP puncta in a concentration-dependent manner ( Figure 3H and Fig.10F Quantification of LC3B-GFP puncta per cell revealed that BAQ ONNs were more potent in inhibiting autophagy than Lys05 ( Fig. 3I ). For further verification, TEM was used to monitor the micromorphological changes of the cells. As expected, BAQ ONN induced the formation of larger autophagic vesicles (AV) or autophagosomes in cells compared with Lys05 and MSDH, which further confirmed the improvement of BAQ ONN autophagy inhibition ( Figure 3J to Figure 3K ). In summary, the findings indicate that BAQ12 NPs and BAQ13 NPs outperform the parent Lys05 in inhibiting autophagy; thus, BAQ ONNs represent a new generation of nanoformulated autophagy inhibitors.
[0254] Proton sponge effect and lysosomal dysfunction. As cationic molecules, BAQ12 and BAQ13 have strong H + Buffering capacity, which is a fundamental characteristic of materials with proton sponge effect ( Figure 2C ). The above TEM results show that BAQ ONN can significantly enlarge lysosomes ( Figure 3J to Figure 3K ), demonstrating the proton sponge effect of BAQ ONN. To further investigate these effects, RNA sequencing (RNA-seq) was used to characterize the transcriptomic changes of MIA PaCa-2 cells after treatment. A total of 13,234 genes were tested, and their expression levels in the vehicle, Lys05, and BAQ13 groups were compared. Using volcano plot analysis, 165 differentially expressed genes (DEGs) were found in the Lys05 group compared with the vehicle group (fold change ≥ 2 and p-value ≤ 0.05), including 62 upregulated genes and 103 downregulated genes. In contrast, 390 DEGs were found in BAQ13-treated cells, including 209 upregulated genes and 181 downregulated genes ( Fig.11A Enrichment analysis of this gene set using the Kyoto Encyclopedia of Genes and Genomes (KEGG) revealed that BAQ13 NP induced a strong upregulation of lysosome-related genes, such as V-ATPase genes, Cl-channel genes, protease genes, and lysosomal-associated membrane protein (LAMP) genes ( FIG. 4A to FIG. 4C and Fig. 11B ). qPCR analysis also confirmed the upregulation of V-ATPase genes and Cl- channel genes, which significantly indicated that BAQ ONNs have strong proton sponge properties ( FIG. 4D to FIG. 4E ).
[0255] The upregulation of important lysosomal enzyme genes such as cathepsin and NEU1 also emphasized the lysosomal dysfunction caused by BAQ ONN ( FIG. 4B to FIG. 4C LAMP genes, which are thought to be partially responsible for maintaining lysosomal integrity, were also upregulated, suggesting a function for BAQ ONN in lysosomal disruption ( Fig. 11C BAQ ONN-treated groups showed high transcriptional levels of pro-apoptotic genes (BAX, BAK1, BAD, BIM, and PUMA), revealing an enhanced pro-apoptotic effect ( FIG. 11C to FIG. 11D BAQ13 NPs induced the accumulation of acid sphingomyelinase (ASM) precursor sphingomyelin (SM) and led to a decrease in the level of its product ceramide (Cer) ( Fig.11E In addition, the levels of phospholipase A (PLA) precursors including phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylserine (PI) were decreased, and the levels of their corresponding products lysophosphatidylcholine (LPC), lysophosphatidylethanolamine (LPE), and lysophosphatidylserine (LPI) were increased ( Fig.11F ).
[0256] The nanocarrier of the present invention may also include 1 It is a conjugate of pheophorbide a to form pheophorbide a bisaminoquinoline conjugate (PBC). PBC nanoparticles are lysosome-targeted, morphologically transformable nanoassemblies. PBC nanoparticles have a liposome-like morphology under physiological conditions and can be converted into nanofibers after accumulation in lysosomes. The nanofibers formed in lysosomes can cause lysosomal dysfunction and trigger apoptosis of cancer cells. Due to the inclusion of photosensitive groups in the structure, this nanoparticle also supports efficient lysosome-based photodynamic therapy, which can essentially overcome autophagy-related drug resistance.

[0258] Cell lines and cell culture. Human pancreatic cancer cell lines (MIA PaCa-2, BXPC3, and PANC-1) were originally purchased from ATCC and were kindly provided by the laboratory of Dr. Shiro Urayama. HT29, HCT116, H460, MCF7, NIH / 3T3, and IMR-90 cell lines were purchased from ATCC. Bone marrow cells were collected from the leg bone marrow of FVB / N mice. Cells were cultured according to ATCC protocols at 37°C in a humidified atmosphere of 5% CO2 / 95% air using 10% fetal bovine serum, 100 μg mL -1 Penicillin and 100 units mL -1 All cells were cultured in the appropriate medium containing streptomycin. All cell lines were routinely tested for mycoplasma contamination.
[0259] Establishment of patient-derived pancreatic cancer stem cells (PCSCs). Pancreatic patient tissue was donated by the laboratory of Dr. Shiro Urayama at the University of California, Davis (UC Davis) Medical Center. Patient consent for the use of “residual clinical biospecimens” was obtained in accordance with the Institutional Review Board (UC Davis IRB protocol #244896). Patient tumor tissue was collected using collagenase IV and dispase (Stem Cell Technologies, Vancouver, Canada) and filtered through a 70 μm filter. Cells were isolated by labeling with the following antibodies (Biolegend, CA, USA): anti-CD44 (IM7, catalog number 338823), anti-CD326 (9C4, catalog number 324207), and anti-CD24 (ML5, catalog number 311119), and using a BD FACSAria II cell sorter ( Fig.16). Purified PCSCs were collected and maintained in Essential 8Flex medium (Thermo Fisher Scientific) and trypsinized using a gentle cell dissociation reagent (Stem Cell Technologies, Vancouver, Canada). In the tumor sphere formation assay, cold single-cell suspensions of PCSCs in Essential 8Flex medium were mixed with cold Matrigel (1:1, volume ratio), and then they (100 μL) were slowly and evenly dripped into the center of the wells on a 24-well plate (5,000 cells per well). Matrigel was allowed to solidify in a humidified incubator at 37°C for 45 min-60 min, and warm culture medium (500 μL) was added to each well. Tumor spheres were allowed to form within two weeks. For in vivo tumorigenicity, PCSCs were counted and resuspended in a mixture of PBS and Matrigel (1:1) and subsequently injected subcutaneously into the flank of NRG mice.
[0260] Cell viability, cell growth and colony formation. Cell viability was assessed by MTS assay. Briefly, cells in 96-well plates (4,000 cells per well) were treated as indicated and then incubated with MTS reagent for 4 h. OD values (490 nm) were measured by microplate reader. Results are shown as given by the formula [(OD 治疗 -OD 空白 ) / (OD 对照 -OD 空白 )×100%] calculated average cell viability. Drug combination data were analyzed by Combenefit 2.02. In the cell growth assay, cells in 6-well plates (50,000 cells per well) were treated as indicated and manually counted every 24 h. Colony formation assays were also performed on 6-well plates with a starting density of 1,000-2,000 cells per well. After incubation for 10-20 days as indicated, the cells were washed with PBS and stained with a solution of crystal violet and methanol for 20 minutes.
[0261] Apoptosis and caspase 3 / 7 activity. Cell apoptosis was measured using the FITC-Annexin V / PI apoptosis detection kit (AnaSpec). Briefly, treated cells were stained according to the manufacturer's instructions and detected on a BD FACSCanto II flow cytometer. Data were analyzed by FlowJo 7.6.1. In the caspase 3 / 7 activity assay, cells in 96-well plates (10,000 cells per well) were treated as indicated, followed by the addition of the AMC caspase 3 / 7 assay kit (50 μL per well, AnaSpec). Fluorescence intensity (λ) was recorded by a microplate reader. ex =356nm, λem =442nm).
[0262] Cellular uptake and deacidification. For cellular uptake, Alexa Fluor 488-dextran (10 kDa, 100 μg mL -1 Lysosomes were labeled with BAQ NPs (10 μM, 1:10, mass ratio) for 36 h and then incubated with DiD-loaded BAQ NPs (10 μM, 1:10, mass ratio) for 2 h. In the lysosomal deacidification assay, cells were treated for 2 h and incubated with LysoTracker Red (100 nM, Thermo Fisher) for 1 h. Cell images were obtained using a Zeiss confocal microscope and analyzed by Zen 2.3 and ImageJ 1.51s.
[0263] Lysosomal integrity. Lysosomal integrity in living cells was measured by staining with AO (Thermo Fisher Scientific) or AlexaFluor 488-dextran (10 kDa). For AO staining, treated cells were incubated with AO (2 μg mL -1 ) and incubated for 1 h. For dextran staining, cells loaded with dextran were exposed to treatment for 12 h. Images were captured under a Zeiss confocal microscope and analyzed by Zen2.3 and ImageJ 1.51s.
[0264] LC3B-GFP imaging. Cells in 96-well plates (5,000 cells per well) were transfected with the autophagy sensor LC3B-GFP (Thermo Fisher) for 12 h. After 4 h of treatment as indicated, cells were visualized by fluorescence microscopy (Olympus). Spots in each well were quantified using ImageJ 1.51s.
[0265] Lysosome isolation and cathepsin release. Lysosomes were isolated using a lysosome enrichment kit (Thermo Fisher Scientific) according to the manufacturer's protocol. Aliquots of isolated lysosomes were incubated at 37°C for 12 h as indicated and then centrifuged at 15,000×g for 30 min at 4°C to pellet intact lysosomes. After incubation with 200 μM fluorescent cathepsin B substrate III (Z-Arg-Arg-AMC) for 2 h, the amount of cathepsin B released into the supernatant was determined (Ex=380 mm, Em=460 mm).
[0266] Hemolysis. Red blood cells (2%) dissolved in PBS (10 mM, pH 7.4) were incubated with NPs at 37°C for 4 h. After centrifugation at 500 × g for 5 min, the extent of hemolysis was determined spectrophotometrically based on the amount of hemoglobin (540 nm) in the supernatant. The hemolysis test was used to evaluate the pH-dependent decontamination ability and toxicity of the NPs.
[0267] Western blotting. Cells or tumor samples were lysed with RIPA buffer (Thermo Fisher Scientific). After centrifugation at 4°C (15 min, 12,000×g), the concentration of protein in the supernatant was determined by Bradford protein assay dye (Bio-Rad). Immunoblotting was performed routinely and ChemiDoc TM MP Imaging System was used for imaging.
[0268] TEM of cells and tumor tissues. MIA PaCa-2 cells (30,000 cells per well, Lab-Tek) in 8-well slides were treated for 48 h as indicated. Freshly harvested tumors were cut into 1 mm 3 The samples were fixed with 0.1 M cacodylate buffer containing 2.5% glutaraldehyde and 2% paraformaldehyde, transferred to carbon square grids, and then observed under a Talos L120C TEM.
[0269] RNA-seq. Total RNA was extracted from treated MIAPaCa-2 cells (5 μM, 24 h) using the RNeasy mini kit (Qiagen, Germany). Samples were submitted to the Genomics Shared Resource (GSR) of the UC Davis Comprehensive Cancer Center for RNA-Seq analysis. Stranded RNA-seq libraries were prepared from 100 ng of total RNA using the NEBNext Ultra Directional RNA Library Preparation Kit (New England BioLabs). Subsequently, the libraries were combined for multiplex sequencing (2×150 bp, double-end, >20×10 6 Reads / sample). Data of normalized gene read counts were analyzed using fold change and t-test. Differentially expressed genes (DEGs) were collected for signaling pathway enrichment by Funrich software 3.1.3. Gene sets were from the MSigDB database (Broad Institute). GSEA was performed online using GSEA version 3.0 in the KEGG gene set category with the following parameters: n = 1,000 permutations, with p-adjustment < 0.05 and FDR < 0.05 considered significant.
[0270] qPCR. Total RNA was isolated using TRIZOL reagent (Invitrogen) and phenol-chloroform extraction. cDNA was synthesized using 2 μg of total RNA in a 20 μL reaction using SuperScript II reverse transcriptase (Invitrogen). The resulting cDNA was diluted 1:20 in nuclease-free water, and 4 μL was used for each qPCR reaction in triplicate. qPCR was performed on a CFX96 real-time PCR detection system (Bio-Rad) including a non-template negative control using Power SYBR Green PCR premix (Thermo Fisher). Amplification of GAPDH was used to normalize the level of mRNA expression. Primer sequences are listed in Table 3.
[0271] Table 3: Primers and sequences used for RT-PCR analysis.
[0272]
[0273]
[0274] Lipidomics.MIA PaCa-2 cells were treated with compounds (2.5 μM) for 48 h, and 1.5 million cells per group were collected to prepare routine samples for RPLC-QTOF analysis. Samples were run on a Vanquish UHPLC system, followed by data acquisition using a Q-Exactive HF hybrid quadrupole-orbitrap mass spectrometer. LC-MS data were processed using MS-DIAL 3.70. Statistical analysis was performed by first normalizing the data using the sum of known values or mTIC normalization to scale each sample. The normalized peak heights were then submitted to R 3.5.1 for statistical analysis. ANOVA analysis was performed with FDR correction and post hoc tests.
[0275] In vitro antitumor activity of BAQ derivatives. To systematically study the in vitro antitumor effect, three pancreatic cancer cell lines (MIA PaCa-2, BxPC-3, and PANC-1) and two colon cancer cell lines (HT29 and HCT116) were selected for 48 h MTS assay. BAQ ONN showed an IC of 1 μM to 3 μM. 50 values, and thus the potency is approximately 5, 30, and 20 times that of Lys05, HCQ, and MSDH, respectively ( Figure 4F , Fig.12 These results also showed that treatment with BAQ12 or BAQ13 alone was more effective than treatment with Lys05 and MSDH combined, indicating that significant pharmacodynamic synergy occurred when the pharmacophores were fused. The results of cell growth and colony formation assays further demonstrated the inhibitory effect of BAQ ONN on tumor cells ( Figures 4G to 4H ). The improved anticancer activity of BAQ ONNs can be attributed to their multiple functions of inducing LMP, lysosomal dysfunction, and autophagy inhibition in cancer cells; these effects are considered to be important triggers of apoptosis. To examine the pro-apoptotic effects of BAQ ONNs, apoptotic signals were subsequently detected in MIA PaCa-2 and HT29 cells. BAQ ONN treatment resulted in a significant increase in caspase 3 / 7 activity and apoptosis levels ( FIG. 4I to FIG. 4J ). The control Lys05 increased apoptotic signal in a concentration-dependent manner, but its 50 The effects at high concentrations of BAQ ONN were still milder than those at low concentrations of BAQ ONN. These results suggest that cancer cells are more likely to undergo apoptosis when treated with the multifunctional BAQ entity than when treated with Lys05, whose primary function is autophagy inhibition. In addition, non-cancer cell lines, including IMR-90 cells, NIH / 3T3 cells, and bone marrow cells, showed relative insensitivity to BAQ ONN compared to a panel of cancer cell lines, indicating the relatively high safety profile of these compounds ( Fig.12 and Table 4).
[0276] Table 4: Calculated IC50 values. Data are presented as mean ± SD.
[0277]
[0278] In vitro antitumor activity of BAQO derivatives. The in vitro antitumor effect of BAQO derivatives was investigated in pancreatic cancer stem cells (PCSCs). BAQ12O ONN showed an IC of less than 5 μM 50 value( Fig. 22B ), while other BAQO derivatives showed no toxicity at concentrations up to 100 μM. These results suggest that BAQO derivatives can be versatile and used as therapeutic agents or drug delivery agents without causing cytotoxicity.
[0279] Example 4: In vivo studies
[0280] Animal model. To establish a subcutaneous xenograft model, 5 × 10 6 MIA PaCa-2 cells, 2×10 6 HT29 cells or 2 × 10 4 PCSCs were injected subcutaneously into the right flank of nude or NRG mice.
[0281] Animal husbandry. All animal experiments were performed in accordance with protocols approved by the Institutional Animal Care and Use Committee of the University of California, Davis (#20265). Female mice (4-6 weeks) including BALB / c nude mice (Envigo), NRG mice (Jackson Laboratory), and FVB / N mice (Charles River) were purchased and group-housed under standard conditions (22 ± 1 °C, 50%-60% humidity, 12 h light / 12 h dark cycle, free access to food and water).
[0282] In vivo treatment plan. MIA PaCa-2 xenograft tumors (approximately 100 mm 3 ) were randomly divided into 5 groups (n=6) and then injected iv every three days as indicated. For the HT29 xenograft model, 100 mm 3 Six groups of nude mice (n=6) with tumors were administered vehicle (saline, iv), Lys05 (ip), BAQ12 NP (iv), BAQ13 NP (iv), and irinotecan (ip). Treatment of the HT29 model was stopped on day 24, and then the survival of each group of mice was recorded. 3 Mice with tumors were considered dead. For co-delivery studies, NRG mice bearing PCSC tumors (n=5) were treated every three days with vehicle (saline, iv), nabucasin (ip), BAQ13 NPs (iv), BAQ13 NPs + nabucasin (iv and ip, respectively), and BAQ13 NPs @ nabucasin (iv). Tumor volume and body weight were recorded before each drug administration. At the end of treatment, mice were sacrificed and tumors were collected for further analysis.
[0283] In vivo toxicity study. The toxicity of BAQ NPs was studied in female FVB / N mice by iv injection. The mice were administered various concentrations (10 mg kg -1 , 20mg kg -1 or 40 mg kg -1 ) of Lys05, liposome@Lys05, BAQ12 NP and BAQ13NP. The status of the mice was monitored daily and their body weight was recorded every two days. Blood samples were collected and sent to the UCD Comparative Pathology Laboratory for complete blood count (CBC) and serum chemistry tests.
[0284] In vivo pharmacokinetic study. A catheter for drug injection and blood collection (Harland, Indianapolis, IN, USA) was implanted in the jugular vein of female Sprague-Dawley rats (200 g-250 g). Rats (n = 3) were injected with free DiD, BAQ12 NP@DiD (10:1, mass ratio) and BAQ13 NP@DiD (10:1, mass ratio) containing an equivalent dose of DiD (0.5 mg kg -1 ). Blood samples were collected at designated time points and then centrifuged to obtain plasma. Plasma was diluted with DMSO (1:100) and the fluorescence intensity (λ Ex =595nm,λ Em =665nm).
[0285] In vivo / in vitro biodistribution. Nude mice bearing HT29 tumors were treated with 1.0 mg kg -1 BAQ13NP@DiD (10:1, mass ratio) was administered iv. In vivo imaging studies were performed at corresponding time points. Organs (brain, heart, lung, liver, spleen, kidney, intestine, and muscle) and tumors were collected from mice for ex vivo imaging. BAQ13 NP@NAPA+DiD (10 / 2.5 / 1.0 mg kg -1 , iv) Biodistribution. In vivo and ex vivo imaging studies were performed as described above.
[0286] Statistics. Statistical analysis was performed using GraphPad Prism 7.0. Data are presented as mean ± SD, n = biological replicates or independent nanoparticle sample replicates. p values were calculated using one-way ANOVA with Tukey's multiple comparison test or two-tailed Student's t-test as indicated in each figure legend. ns., not significant; *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001.
[0287] Data availability. RNA-seq data have been deposited in the Gene Expression Omnibus (GEO) database under accession code GSE154323 [https: / / www.ncbi.nlm.nih.gov / geo / query / acc.cgi?acc=GSE154323].
[0288] Pharmacokinetics, Biodistribution, and Toxicity. The pharmacokinetics of BAQ ONN were studied in Sprague-Dawley rats by intravenous (iv) injection. Figure 5AAs shown in Table 5, the serum concentration of BAQ ONN was higher than that of free DiD at the same time points until 48 h, indicating that the plasma clearance of BAQ ONN was slower than that of DiD due to the nanoscale characteristics of BAQ ONN. DiD-labeled BAQ13 NPs were also used to study the biodistribution of NPs in nude mice bearing HT29 tumors. As expected, both in vivo and ex vivo imaging showed that the fluorescence signal of BAQ13 NPs was clearly discernible in the tumor area but not in the surrounding normal tissues at 12 h and 24 h after injection, indicating the tumor-targeted biodistribution of BAQ ONN ( FIG. 5B to FIG. 5C and FIG. 13A to FIG. 13B This targeting ability may be due to the relatively high permeability of tumor blood vessels, which enables the passive accumulation of nanotherapeutics. The free DiD (control) group showed high signals in the lungs but not in the tumor sites ( FIG. 13A to FIG. 13B ). In particular, the fluorescence ratio of tumor to lung in the BAQ13 NP group was about 4 times that in the free DiD group. These results indicate that BAQ ONN has tumor-targeted biodistribution.
[0289] Table 5. Pharmacokinetic parameters calculated using Kinetica 5.0.
[0290]
[0291] Then, a hemolysis test was performed to evaluate the safety of BAQ ONN. -1 -1mg mL -1 Lys05, BAQ12 NP, or BAQ13 NP were used to treat erythrocytes, close to the working concentration used in animal treatment studies ( Fig. 13C ). Use with concentrations higher than 0.5 mg mL -1 Compared with the treatment with BAQ12 NP or BAQ13NP, the treatment with the control drug Lys05 resulted in a significantly higher hemolysis rate, indicating that BAQ ONN is safer than Lys05. In the following animal toxicity study on FVB / N mice, it was found that after iv administration, even at 10 mg kg -1 Lys05 treatment also resulted in acute death of mice at low concentrations; in contrast, BAQ ONN treatment resulted in low mortality and no weight loss, revealing that BAQ ONN is safe when administered by iv injection ( FIG. 13D to FIG. 13E ). Since BAQ13 NP is at 40 mg kg -1BAQ13 NPs were better tolerated by mice than BAQ12 NPs, as they did not cause any mortality. This result may be due to the high stability and low CAC of BAQ13 NPs. Liposomes were used to encapsulate Lys05 (Liposome@Lys05), and the formulation was found to be safe for iv injection ( FIG. 13E to FIG. 13F Because autophagy plays an important role in intestinal homeostasis, intraperitoneal (ip) administration of BAQ12 NP or BAQ13 NP, which results in enhanced autophagy inhibition, may cause intestinal disturbances and weight loss in mice. - 1 H&E staining of tissue sections and hematological indices did not show obvious abnormal changes in BAQ NP-treated mice, further indicating that iv administration of BAQ ONN was well tolerated ( FIG. 14A to FIG. 14E ). Therefore, BAQ ONNs should be administered by iv injection rather than ip injection to study their advantages in vivo.
[0292] Antitumor effect in mice as a single agent. After demonstrating the safety of BAQ ONN, the anticancer efficacy of NP was evaluated in a pancreatic xenograft model of MIA PaCa-2 cells. 3 ) were randomly divided into five groups (n=6): saline (iv) group, Lys05 (ip) group, liposome@Lys05 (iv) group, BAQ12NP (iv) group and BAQ13NP (iv) group. Then, 20 mg kg -1 The mice were treated with a dose of FIG. 5D to FIG. 5F The results in showed that treatment with BAQ12 NPs or BAQ13NPs significantly slowed tumor growth without interfering with body weight. The control drug Lys05 showed no therapeutic effect under this condition, but its nanoformulation liposome@Lys05 caused increased tumor inhibition, which highlights the advantages of nanomedicines in drug delivery. It should also be emphasized that the single-component formulations of self-assembled BAQ12 NPs or BAQ13 NPs were significantly more effective than free Lys05 or nanoformulated Lys05. These findings clearly illustrate the potential advantages of BAQ ONN in drug discovery and drug delivery.
[0293] To further understand the in vivo effects of BAQ ONN, tumor tissues were harvested for histological evaluation. Significant cell destruction, increased levels of cleaved caspase-3, and decreased Ki67 expression were observed in both BAQ ONN groups, indicating that tumors treated with BAQ ONN tended to die or become apoptotic or quiescent ( Figure 5G to Figure 5H LC3 expression was increased in both BAQ ONN groups ( Figure 5H); This finding is an important clue to explain the in vivo autophagy inhibition effect of the two BAQ ONNs. Subsequent immunoblot analysis further demonstrated that autophagy in tumors was blocked by BAQ ONN. In addition, tissue ultrastructure was observed by TEM and it was found that tumors treated with BAQ ONN contained more large AVs than the tumor group. In the above assays, the Lys05 nanoformulation liposomes@Lys05 also exhibited some effects that were not observed with solvent or free Lys05. However, the effect of liposomes@Lys05 was much weaker than that of BAQ12 NP or BAQ13 NP. These tissue-level results reveal the excellent autophagy inhibition effect of BAQ ONN in vivo.
[0294] The therapeutic effect of BAQ ONN in vivo was further demonstrated in another animal model consisting of mice bearing colon HT29 tumors. BAQ ONN administration significantly inhibited tumor growth compared to vehicle or Lys05 administration ( FIG. 15A to FIG. 15B ). And BAQ13 NPs showed better efficacy than BAQ12 NPs. Interestingly, this result contradicts the results obtained in the in vitro proliferation assay, which demonstrated that BAQ12 NPs were more effective than BAQ13 NPs. This discrepancy could be explained by the differences in self-assembly behavior and pharmacokinetic properties between BAQONNs ( Figure 2G , Figure 5A ). In addition, BAQ13 NP was also more effective than FDA-approved irinotecan at reported therapeutic doses, while BAQ12 NP showed similar effects to irinotecan. Survival analysis revealed that BAQ13 NP treatment resulted in significantly longer survival (median survival of 48 days) than the vehicle group and irinotecan group (median survival of 21 days or 36 days, respectively) ( Fig. 15C and Table 6). Due to the integration of their multiple advantages in pharmacodynamic effects and pharmacokinetic properties, hybrid BAQ ONNs show great potential in in vivo cancer treatment as a single agent.
[0295] Table 6: Median survival of mice bearing HT29 tumors. n = 6 mice per group.
[0296]
[0297] Dual Role of BAQ ONN in Combination Therapy. Combination therapy based on autophagy inhibition can sensitize tumors to conventional treatments, but the current limitation is the insufficient efficacy of autophagy inhibitors. In addition, the different pharmacokinetics and different dosing regimens of the drugs used in combination therapy are inconvenient. Considering the 30-fold higher anticancer potency of BAQ ONN than HCQ and their considerable potential to encapsulate additional drugs, BAQ ONN may be able to simultaneously address both pharmacodynamic and pharmacokinetic issues. To test this hypothesis, a xenograft model with high heterogeneity and high tumor stroma ratio was established by using a pancreatic cancer stem cell (PCSC) line from patient-derived pancreatic adenocarcinoma tissue ( FIG. 6A to FIG. 6B and Fig.16 In vitro results showed that BAQ ONNs have similar functions in inhibiting lysosomes and autophagy in PCSCs, thus exhibiting potent pro-apoptotic and anti-proliferative activities ( FIG. 6C to FIG. 6E and 17A to 17C ). Nabucacin, a STAT3 inhibitor that can be encapsulated in BAQ13 NPs, was selected for combination therapy because it can induce autophagy and synergize with BAQ13 NPs ( Fig. 6F and Fig.17D The mice were randomly divided into 5 groups, including vehicle (saline) group, nabucasin group, BAQ13 NP group, mixture (BAQ13 NP+nabucasin) group and BAQ13 NP@nabucasin group ( FIG. 6G to FIG. 6I ). BAQ13 NPs modestly inhibited tumor growth, while nabucasin itself did not show antitumor effects under these conditions. Although in vitro synergistic effects of nabucasin and BAQ13 NPs were observed, the mixed group did not show enhanced effects in vivo. This lack of in vivo effect may be due to the poor solubility and low delivery efficiency of nabucasin. When loaded in BAQ13 NPs (BAQ13 NP@nabucasin), nanoformulated nabucasin achieved satisfactory antitumor effects by synergizing with BAQ13 NPs. Significant changes in tumor histology were also observed in the BAQ13 NP@nabucasin group, with cells showing low proliferation activity ( Figure 6J In addition, no mice in the treatment group showed significant systemic toxicity ( Fig.6I and Fig.17E To further validate the ability of BAQ13 NPs to deliver nabucasin, another imaging study was performed on the PCSC model by using DiD-labeled BAQ13 NP@nabucasin. The results showed that NPs accumulated significantly at tumor sites rather than in normal organs ( Figures 6J to 6K and Fig.17F ). These interesting results suggest that BAQ13 NPs may be used not only as therapeutic agents but also as delivery vehicles in combination therapies; thus, they show promise for improving cancer treatment.
[0298] Antitumor effects of BAQO derivatives in mice. BAQO derivatives can be formed into nanoparticles and used in in vivo mouse studies. For example, BAQ12O NPs were used to treat mice bearing PCSC tumors. Fig.24A As shown, mice treated with BAQ100 NPs had lower tumor volumes, with significant differences in tumor volume by day 27. Fig. 24B The tumor weight at the end of treatment with BAQ12O NPs was shown to be 50% lighter than that of the control. These interesting results suggest that BAQO derivatives can be used as promising agents for drug discovery and drug delivery.
[0299] Based on the ONN strategy and the principles of pharmacophore hybridization and molecular self-assembly, self-delivering new chemical entities BAQONN were developed. In addition to the properties of improved drug delivery and tumor-targeted biodistribution, these entities also have enhanced abilities to induce lysosomal disruption, lysosomal dysfunction, and autophagy blockade; thus, they exhibit significant anticancer efficacy both in vitro and in vivo. Strikingly, simple BAQ13 NPs were found to display high drug loading efficiency and can effectively synergize and deliver additional drugs, showing promise for use in combination therapies.
[0300] Compared to conventional NPs, which typically have less than 20% active pharmaceutical ingredient (API) content and are complex to synthesize, BAQONNs have 100% API content and are easy to synthesize and scale up. Since they are non-prodrug chemical entities, they are also superior to emerging single-component prodrug NPs. All of these advantages will greatly facilitate their translation into clinical trials. This is an important attempt to expand nanotechnology into the design of new chemical entities. The seamless connection between drug discovery and nanotechnology-assisted drug delivery will enable researchers to develop increasingly advanced nanomedicines that have a wide range of therapeutic and commercial benefits for cancer targeting.
