Abstract
Description
[Technical Field]
[0001] FIELD OF THE DISCLOSURE Embodiments of the present disclosure generally relate to polymeric biologically active compounds having alkylating agents and methods for their preparation. [Background technology]
[0002] Targeted drug conjugates deliver drugs to target cells with little or no off-target activity, unlike, for example, chemotherapy. Typically, targeted drug conjugates contain a biologically active payload or targeting molecule linked to the drug. By combining the inherent targeting ability with the therapeutic effect of the biologically active drug (or moiety), the conjugate can deliver the drug only to the intended target and minimize potential side effects. Antibody-drug conjugates (ADCs) are a type of targeted drug conjugate that has attracted particular attention, for example, for cancer treatment. ADCs for cancer treatment combine the targeting characteristics of monoclonal antibodies with the cancer-killing capabilities of cytotoxic agents, providing a therapy with several advantages over other chemotherapeutic agents. However, the complexity of ADC constructs, particularly challenges associated with the chemical linker between the antibody and the drug, has posed significant challenges to the development of new, effective therapeutic agents. While the first ADC was approved in 2001, it took nearly a decade for the next ADC to be approved. Currently, only Adcetris®, Besponsa®, Enhertu®, Mylotarg®, Padcev®, Polivy®, and Kadcyla® are commercially available worldwide (Zevalin® is approved only in China). Thus, there exists a need in the art for the development of potent targeted drug conjugates with high therapeutic indices and methods for their preparation. The present disclosure fulfills this need and further provides related advantages. Summary of the Invention

[0048] compound As noted above, one embodiment of the present disclosure provides compounds useful as covalent linkers between biologically active moieties, such as alkylating agents, and targeting moieties. In other embodiments, compounds useful as synthetic intermediates for preparing compounds comprising one or more biologically active moieties are provided. Thus, in some embodiments, M 1 is, in each occurrence, independently either i) H or ii) a moiety containing a biologically active moiety, provided that L 1b If H, then M 1 does not exist, and M 2 is, independently at each occurrence, a moiety containing a fluorescent dye, and M 3 is, at each occurrence, independently a moiety that comprises a biologically active moiety. 1 or M 3 is an alkylating agent (e.g., monomethylauristatin F, monomethylauristatin E, SN38, and pyrrolobenzodiazepines), and M 2 is a fluorescent dye (e.g., fluorescein, etc.). According to embodiments disclosed in the present disclosure, a biologically active moiety M is attached to a polymer backbone and any subsequent targeting moiety. 1 and M 3 the number and type of biologically active moieties, the spacing between adjacent biologically active moieties on the polymer backbone (e.g., biologically active moieties M 1 and M 3 This offers numerous advantages, including the ability to control the spacing between the polymer backbone and the biologically active moieties (e.g., how far apart or close each of the alkylating agents are), as well as the spacing between the polymer backbone and the biologically active moieties (e.g., the length of the linker from the polymer backbone). This allows compounds having biologically active moieties that promote the alkylation of guanine (G) in DNA to be constructed such that the biologically active moieties attached to the polymer backbone are positioned at low-energy positions within the minor groove of DNA. The compounds disclosed in the present disclosure have multiple alkylating agents as biologically active moieties, which can form interstrand and / or intrastrand DNA crosslinks, resulting in greater DNA stability.
[0049] The biologically active moiety may be attached to the polymer backbone via a physiologically cleavable linker or a non-cleavable linker. The procedures described in the present disclosure provide the ability to selectively introduce a physiologically cleavable linker and / or a non-cleavable linker. This allows for the synthesis of compounds with both physiologically cleavable and non-cleavable linkers bearing one or more biologically active moieties. In this regard, the biologically active moieties can be sequentially cleaved in response to physiological conditions. Furthermore, M 1 and the biologically active moiety of M 2 The ratio of biologically active moieties can be fine-tuned based on the type of disease, disease progression, and therapy. Additionally, compounds can be synthesized with multiple biologically active and fluorescent moieties attached by physiologically cleavable and / or non-cleavable linkers.
[0050] Some embodiments of the present disclosure provide combinations of therapeutic agents, targeting moieties, and dye moieties (e.g., chromophores or fluorophores) that can be used for simultaneous targeting, treatment, and detection. The ease of coupling of polymer-drug constructs to targeting agents such as antibodies, antibody fragments, proteins, or other clinically interesting agents provides utility for a wide variety of interesting applications (e.g., surface chemistry, assay development, etc.). Thus, in some embodiments, M 2 is a chromophore or fluorophore (e.g., FITC, 5-FAM, 6-FAM, etc.). Certain embodiment compounds also provide other desirable properties, including enhanced permeability and retention. In addition to providing the necessary solubility characteristics, the chemical characteristics of embodiment compounds of the present invention can be tailored to modulate the ability of the compound to penetrate and be retained in diseased cells / tissues. These characteristics allow for effective delivery of biologically active agents by increasing permeability and increased efficacy by enhancing retention.

A "protected form" of Q refers to a moiety that is less reactive than Q under given reaction conditions, but that can be converted to Q under conditions that preferably do not decompose or react with other moieties of the compound of structure (I). Those skilled in the art can derive an appropriate protected form of Q based on the particular Q and the desired end-use and storage conditions. For example, if Q is SH, the protected form of Q includes a disulfide, which can be reduced to expose the SH moiety using commonly known techniques and reagents.
[0106] Exemplary Q moieties are provided in Table I below. [Table 2-1] [Table 2-2] [Table 2-3]
[0107] It should be noted that in some embodiments, when Q is SH, the SH moiety will have a tendency to form a disulfide bond with another sulfhydryl group of another compound, for example, of structure (I). Thus, some embodiments include compounds of structure (I) that are in the form of a disulfide dimer, where the disulfide bond is derived from the SH Q group.
[0108] In other embodiments, the Q moiety is conveniently masked (e.g., protected) as a disulfide moiety, which can be subsequently reduced to provide an activated Q moiety for conjugation to a desired analyte molecule or targeting moiety. For example, the Q moiety may have the following structure: [ka] and wherein R is an optionally substituted alkyl group. For example, in some embodiments, Q has the following structure: [ka] and a disulfide moiety having the formula: In the formula, n is an integer from 1 to 10.

Furthermore, in some embodiments, the alkylating agent is protected with protecting groups such as allyloxycarbonyl (-Alloc) and tert-butyldimethylsilyl ether (-TBS) to survive the DNA synthesis cycle. The Alloc protecting group can be easily cleaved with a palladium catalyst, e.g., Pd(PPh) with PhSiH, to give the corresponding amine. The TBS protecting group can be cleaved with a fluoride source, such as tetra-n-butylammonium fluoride (TBAF), to give the corresponding alcohol. Once deprotection is complete, the PBD moiety is activated and capable of alkylation. At this point, the PBD moiety remains protected with a protecting group until the DNA synthesis cycle is complete. Deprotection can then convert the alkylation-inactive protected PBD moiety into an alkylation-active deprotected PBD moiety.

[0238] A typical DNA synthesis cycle [ka]
[0239] Oligomerization is typically initiated by removing a protecting group (e.g., dimethoxytrityl group, DMTr) to expose a free -OH (hydroxyl) group (Step 1, detritylation). A subsequent coupling step introduces a phosphoramidite monomer that reacts with the free OH group to form a new covalent bond with phosphorus, with concomitant loss of the diisopropylamine group (Step 2, coupling). The resulting phosphite triester is oxidized (e.g., with I2 and pyridine) to the more stable phosphate ester (Step 3, oxidation), and a capping step renders any remaining free OH groups unreactive (Step 4, capping). The new product, a phosphate oligomer, contains the DMTr-protected OH group, which can be deprotected to restart the synthesis cycle and add another phosphoramidite monomer to the oligomer.
[0240] Customization is achieved by the selection of phosphoramidite monomers in Step 2. The nature of L (i.e., linker group) and M (i.e., chemotherapeutic agent) in the above scheme are selected to synthesize the desired compound of structure (I), (III), or (IV). M may optionally be absent to incorporate desired spacing between M moieties. One of skill in the art can select multiple monomer types to arrive at compounds of the present disclosure containing multiple therapeutic agents and / or other moieties (e.g., fluorophores or chromophores) with simultaneous variability in the linker group.
[0241] Several steroid and vitamin phosphoramidites are commercially available and can be used in the DNA synthesis cycle described above, including cholesterol phosphoramidite and tocopherol / tocotrienol phosphoramidite, as shown below. [ka]
[0242] Basic Reaction Scheme 1 (Phosphoramidite) [ka] Reaction Scheme I illustrates a method for preparing a phosphoramidite intermediate useful in preparing compounds of structure (I). Referring to Reaction Scheme I, G 1represents a desired moiety containing a carboxylic acid functional group (e.g., a drug moiety such as auristatin F or SN38), L represents a bivalent linker moiety (e.g., an alkylene or alkylene ether), X represents a leaving group (e.g., a halo such as Cl), and PG represents a protecting group (e.g., 4,4'-dimethoxytriphenylmethyl). Step 1 of Reaction Scheme I begins with activation of the carboxylic acid functional group of the first compound shown using known reagents (e.g., HATU and DIPEA in DMF) under basic conditions. The activated acid is then reacted with an amine to yield the reaction product of Step 1. The resulting diol is then protected under standard conditions (e.g., 4,4'-dimethoxytriphenylmethyl chloride and pyridine). The protected product is then reacted with 3-((chloro(diisopropylamino)phosphanyl)oxy)propanenitrile (or other appropriate reagent) to yield the desired compound of structure (VII) shown above.
[0243] The resulting compound of structure (VII) can then be used to synthesize the desired compound of structure (I) by reaction under well-known (automated) DNA synthesis conditions. In addition to the compound of structure (VII), additional repeat units can be incorporated to arrive at the final compound of structure (I). Generally, the following structure is obtained: [ka] A compound having the formula: During the ceremony, L is a desired linker moiety (including, for example, PEG or a dye-containing moiety).

[0247] Example 1 Synthesis of DMT-protected gemcitabine compounds [ka]
[0248] Gemcitabine (0.5057 mmol) was added to a dry round-bottom flask with a magnetic stir bar under an inert gas blanket, followed by anhydrous pyridine (5.06 mL). The reaction flask was then transferred to an ice-water bath (0 °C) and cooled with mixing until thermal equilibrium was reached (approximately 10 min). 4,4'-Dimethoxytrityl chloride (0.257 g, 0.759 mmol) was then added to the cooled mixture with continuous mixing under inert gas. The reaction mixture was allowed to warm to room temperature and then sampled for TLC analysis. Once the reaction was confirmed to be complete, any remaining unreacted 4,4'-dimethoxytrityl chloride was quenched by adding methanol to the reaction mixture (0.160 g, 5.06 mmol). The solvent was removed by rotary evaporation under vacuum (10 mbar) and heating (55 °C). The concentrated residue is then suspended in toluene (5.06 mL) and the toluene is removed by rotary evaporation under vacuum (1000 Pa (10 mbar)) and heating (55°C), and this operation is repeated twice. The crude product is dissolved in dichloromethane (5.06 mL), washed with sodium bicarbonate (5.06 mL, saturated aqueous solution), and separated. This process is repeated once. The separated organic phase is washed with sodium chloride (5.06 mL, saturated aqueous solution) and separated. The separated organic phase is dried over anhydrous sodium sulfate, and the sodium sulfate is removed by filtration. The product containing organic phase is sampled for TLC and LC-UV / MS analysis.

After stirring overnight, TLC (silica plates with F254, dichloromethane:methanol elution 9:1) indicated the reaction was complete. The reaction mixture was concentrated on a rotary evaporator and then partitioned between dichloromethane and water. The solvent layers were separated in an extraction funnel, and the aqueous layer was extracted three more times with dichloromethane. The organic layers were combined, dried over sodium sulfate, and concentrated under reduced pressure. The product was used in the next step without further purification.
[0258] Step 2 A 250 mL round-bottom flask equipped with a magnetic stir bar was charged with the Boc-Ala-Ala derivative (2.5 g, 4.8 mmol) prepared in the previous step. Dichloromethane (30 mL) and DMF (10 mL) were added, and the mixture was stirred. To this was added 4 M hydrochloric acid in dioxane (30 mL, Sigma catalog no. 345547), and the mixture was stirred. After 1 h, TLC (silica plate with F254, eluted with 9:1 dichloromethane:methanol) indicated the reaction was complete. The solvent was removed by rotary evaporation. Acetonitrile (50 mL) was added, and the mixture was shaken for several minutes. The heterogeneous mixture was cooled to 4 °C for 1 h, and then the solid was collected by filtration (2.0 g).

The solid yield was 1.32 g. The product was confirmed by LC-MS.
[0260] Step 4 A small 20 mL glass vial was charged with 6,7-dihydroxy-4-oxaheptylamine (443 mg, 3.0 mmol, Berry & Associates catalog number LK4010) and DMF (5 mL). The sample was warmed for 10 minutes on a heat plate set at 60 °C before assembling the other components of the reaction. A 200 mL round-bottom flask was charged with the succinylated Ala-Ala derivative (1.3 g, 2.5 mmol) prepared in the previous step, a magnetic stir bar, and DMF (18 mL). HATU (1.1 g, 3.0 mmol, Anaspec) was added, and the mixture was stirred for 5 minutes. The DMF-aminodiol solution in the 20 mL glass vial was added to the reaction flask.

Alanine-linked camptothecin can also be prepared similarly using camptothecin derivatives bearing a hydroxyl group at the 11-position rather than the 10-position.
[0264] Step 7 A 200 mL round-bottom flask equipped with a magnetic stir bar is charged with the diol (1.9 mmol) prepared in the previous step and pyridine (38 mL). 4,4-Dimethoxytrityl chloride is added to the solution in one portion. The flask is capped and stirred overnight. The mixture is concentrated under reduced pressure, and the product is isolated by flash chromatography on a 24 g silica column (Teledyne-ISCO) eluting with a dichloromethane:methanol gradient to give the crude product.

[0275] A mixture of CuSO4 (2 mM), sodium ascorbate (10 mM), and tris-hydroxypropyltriazolylmethylamine (THPTA) (4 mM) in water was vigorously stirred at room temperature for 15 minutes.

[0276] Example 10 Basic synthesis of peptide backbone by solid phase synthesis [ka] The above reaction scheme shows an exemplary method for preparing intermediates useful in preparing compounds of structure (III), where PG is a suitable protecting group, X is a functional unit to which a peptide chain may be constructed, the shaded circle is a suitable solid support, and "BAM" is a biologically active moiety or fragment thereof, a prodrug of a biologically active moiety or fragment thereof, a fluorescent dye, an imaging agent, or a radioisotope binding site, with the proviso that at least one occurrence of M is not a fluorescent dye.
[0277] Small porous beads are first treated with functional units, which are attached to the surface of the porous beads. Peptide chains are assembled at the functional unit sites, and remain covalently attached to the beads until cleaved. Once attached, the peptide chains are immobilized on the solid phase and retained during the filtration process, during which liquid reagents and synthesis by-products are washed away.
[0278] The basic cycle of solid-phase synthesis is one of repeated deprotection-wash-coupling-wash cycles. The free N-terminal amine of a peptide attached to a solid support is coupled to an N-protected amino acid group (e.g., with Fmoc or Boc). The newly introduced amino acid unit is deprotected to expose a new N-terminal amine, which can then be further reacted with additional amino acids. This process is repeated to elongate the peptide chain.
[0279] Once all desired amino acids and monomer units have been incorporated into the peptide chain, the peptide chain is cleaved from the bead. Cleavage reagents such as anhydrous hydrogen fluoride or trifluoroacetic acid may be used to cleave the peptide chain from the bead. The peptide chain is then collected, purified, and characterized.
