Abstract
Description
Technical Field
[0001] This invention belongs to the field of polymer chemistry and biomedical technology, specifically relating to a macrocyclic lactone polymer, a composition, its preparation method and application, wherein the compound or composition has the use of inhibiting tumor proliferation activity and can be used to prevent or treat hyperproliferative diseases. Background Technology
[0002] Brefeldin A (BFA) is a macrolide fungal metabolite. It was isolated in 1958 by Singleton et al. from *Penicillium decumbens* (Singleton, VL et al.). Nature (1958, 181, 1072-1073), whose absolute configuration was determined in 1971 by Weber et al. through single crystal, CD, and asymmetric synthesis (Weber, HPet, al.). Helv. Chim. Acta , 1971, 54 (2763-2766). However, BFA is not suitable for clinical use due to its undesirable pharmacokinetic properties (low bioavailability, poor water solubility, low plasma exposure, short plasma half-life, and high toxicity) (Sausville, EA et al.). Cancer. J. Sci. Am. 1996, 2 (52-58). To date, there are no reports on BFA derivatives that can effectively improve pharmacokinetic properties, or other properties such as increasing solubility and reducing toxicity.
[0003] In recent years, nanomedicines have attracted increasing scientific attention due to their significant advantages, such as improved drug solubility, prolonged drug circulation time, and enhanced drug accumulation at tumor sites through enhanced permeability and retention (EPR). Targeted nanomedicines have become an effective means of treating cancer, and to date, several nanomedicines have been used clinically and commercially for the treatment of certain diseases. Therefore, to overcome the aforementioned shortcomings, structural modification of BFA by coupling it with hydrophilic polymer segments via linkers has gained attention, with the aim of finding compounds that can maintain high antitumor activity while possessing favorable pharmacokinetic properties for clinical application.

In other embodiments, the test subject is a human.
[0031] As used in this invention, the term "patient" refers to a person (including adults and children) or other animal. In some embodiments, "patient" refers to a person.
[0032] The term "comprising" is an open-ended expression, meaning it includes the contents specified in this invention, but does not exclude other aspects.
[0033] "Stereoisomers" are compounds that have the same chemical structure but whose atoms or groups are arranged differently in space. Stereoisomers include enantiomers, diastereomers, conformational isomers (rotational isomers), geometric isomers (cis / trans) isomers, and hindered isomers, etc.
[0034] "Chirality" refers to molecules that have the property that they cannot be superimposed on their mirror image; while "chirality" refers to molecules that can be superimposed on their mirror image.
[0035] "Enantiomers" refer to two non-overlapping but mirror-image isomers of a compound.
[0036] A diastereomer is a stereoisomer that has two or more chiral centers and whose molecules are not mirror images of each other. Diastereomers have different physical properties, such as melting point, boiling point, spectral properties, and reactivity. Mixtures of diastereomers can be separated by high-resolution analytical procedures such as electrophoresis and chromatography, for example, HPLC.
[0037] The stereochemical definitions and rules used in this invention generally follow those of S.P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984), McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., “Stereochemistry of Organic Compounds,” John Wiley & Sons, Inc., New York, 1994.
[0038] Many organic compounds exist in an optically active form, meaning they possess the ability to rotate the plane of plane-polarized light. When describing optically active compounds, the prefixes D and L are used. R and S To indicate the absolute configuration of a molecule with respect to one or more chiral centers. Prefix d and l Or (+) and (−) are symbols used to specify the rotation of plane-polarized light caused by a compound, where (−) or l This indicates that the compound is levorotatory. The prefix is (+) or... d The compound is dextrorotatory. A specific stereoisomer is an enantiomer, and a mixture of such isomers is called an enantiomeric mixture. A 50:50 mixture of enantiomers is called a racemic mixture or racemate, which can occur when there is no stereoselectivity or stereospecificity in the chemical reaction.
[0039] Any asymmetric atom (e.g., carbon, etc.) in the compounds disclosed in this invention can exist in racemic or enantiomerically enriched forms, for example ( R )-、( S )-or( R, S The asymmetric atom exists in a configuration form. In some implementations, the asymmetric atoms are in ( R )-or( S - In terms of configuration, it has at least 50% enantiomer excess, at least 60% enantiomer excess, at least 70% enantiomer excess, at least 80% enantiomer excess, at least 90% enantiomer excess, at least 95% enantiomer excess, or at least 99% enantiomer excess.
[0040] Depending on the choice of starting materials and method, the compounds of this invention can exist as one or a mixture of possible isomers, such as racemic mixtures and diastereomers (depending on the number of asymmetric carbon atoms). Optically active ( R )-or( S The )-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituents may be E or Z configurations; if the compound contains a disubstituted cycloalkyl group, the cycloalkyl substituents may be cis or trans configurations.
[0041] Any mixture of stereoisomers obtained can be separated into pure or substantially pure geometric isomers, enantiomers, and diastereomers based on differences in the physicochemical properties of the components, for example, by chromatography and / or fractional crystallization.
[0042] Racemates of any resulting end product or intermediate can be separated into optical enantiomers using known methods, such as by separating the salts of their diastereomers. Racemate products can also be separated by chiral chromatography, such as high-performance liquid chromatography (HPLC) using chiral adsorbents. In particular, enantiomers can be prepared by asymmetric synthesis, for example, see Jacques, et al., Enantiomers, Racemates and Resolutions (Wiley Interscience, New York, 1981); Principles of Asymmetric Synthesis (2 ndEd. Robert E. Gawley, Jeffrey Aubé, Elsevier, Oxford, UK, 2012); Eliel, EL Stereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); Wilen, SH Tables of Resolving Agents and Optical Resolutions p.268 (EL Eliel, Ed., Univ. of Notre Dame Press, Notre Dame, IN 1972); ChiralSeparation Techniques: A Practical Approach (Subramanian, G. Ed., Wiley-VCHVerlag GmbH&Co. KGaA, Weinheim, Germany, 2007).

[0183] Example 11: Solubility Test
[0184] Test objective: To compare the solubility and stability differences between the compound of this invention and BFA.
[0185] Test method: 2 mg BFA and 20 mg of compounds 1, 3, 5, 9, 11 of the present invention were added to 2 mL of 5% solutol + 95% saline solvent, respectively. After sonication for 10 min and suspension for 5 min, the solubility of the compounds was observed and the sedimentation was observed after standing for 3 days. The stability of the solution was analyzed by HPLC.
[0186] The results showed that compounds 1, 3, 5, 9, and 11 of this invention were completely soluble in 5% solutol + 95% saline, remaining clear with no precipitation within 3 days, and the peak areas in HPLC analysis remained essentially consistent over 3 days. BFA, on the other hand, was insoluble, remaining turbid, and showed significant precipitation after 3 days. Compounds 1, 3, 5, 9, and 11 were completely soluble, remaining clear, but precipitation occurred within 3 days, resulting in a slight decrease in HPLC peak area; however, they could be re-dissolved after shaking. Therefore, the solubility of the compounds of this invention (greater than 10 mg / mL) is significantly higher than that of BFA (less than 1 mg / mL), demonstrating a significant advantage in drug delivery.
[0187] Example 12 Cell Proliferation Experiment
[0188] 1) Detection principle:
[0189] CCK-8 Assay: The CCK-8 assay is a highly sensitive, non-radioactive colorimetric method for determining the number of viable cells in cell proliferation or cytotoxicity assays. CCK-8 is bioreduced by intracellular dehydrogenases to produce an orange formazan dye that is soluble in cell culture medium, and the amount of formazan produced is directly proportional to the number of viable cells. The kit used in this method is tetrazolium salt −WST-8 (2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfonylbenzene)-2H-tetrazole monosodium salt), developed by Dojindo Chemical Research Institute. It can be reduced to a water-soluble formazan dye in the presence of the electron carrier 1-Methoxy PMS.

Most compounds also demonstrated significant selectivity, with particularly pronounced anti-proliferative inhibitory effects against human colon cancer cells and bladder cancer cells. Therefore, the compounds of this invention have promising potential applications in inhibiting tumor proliferation.
[0202] Example 13 Acute Toxicity Test
[0203] Experimental objective: To observe the toxic effects of intraperitoneal injection (ip.) of the compound in mice.
[0204] Experimental materials:
[0205] 1) Drug: The compounds of the present invention are prepared into appropriate concentrations for later use.
[0206] 2) Animals: Kunming mice, weighing 18-22g, male. Supplied by Jinan Pengyue Experimental Animal Breeding Co., Ltd., Animal License No.: SCXK (Lu 20140007).
[0207] Test method:
[0208] Kunming mice were randomly divided into groups of six based on body weight: a normal control group, high- and low-dose BFA groups (100 mg / kg and 50 mg / kg, respectively), and high- and low-dose groups of some compounds from this invention (based on the effective amount of BFA). After administration, the animals' behavior, mental state, feeding and drinking responses, and mortality were observed. After 14 days of continuous administration, all animals were weighed, sacrificed, dissected, and visually inspected for any abnormalities.
[0209] Results of intraperitoneal injection test:
[0210] a) Mice in the high-dose BFA group experienced a continuous decrease in body weight, indicating significant toxicity, and died on day 12 after administration. Mice in the low-dose group died on day 14 after administration.
[0211] (b) Animals treated with compounds 1, 3, 5, 9, and 11 of the present invention at both high and low doses showed good mental condition with no deaths. Furthermore, during administration, animals treated with the compounds of the present invention exhibited smoother fur compared to those treated with BFA. Autopsy results after 14 days showed no significant abnormalities in any organ during anatomical observation.
[0212] c) The weight of the animals in the drug-treated group was slightly lower than that of the normal control group, but the difference was not statistically significant.
[0213] The results showed that, compared with BFA, the compound of the present invention had a significant reduction in toxicity after administration to mice, and had a certain degree of attenuation effect.
[0214] Example 14 Pharmacokinetic Evaluation
[0215] Test method:
[0216] SD rats were weighed after a 15-hour overnight fast and randomly assigned to groups based on body weight. An appropriate amount of the test compound was accurately weighed and added to a final volume of 5% DMSO, 10% Solutol, and 85% Saline. The mixture was vortexed or sonicated to obtain a 4 mg / mL administration solution for intravenous injection. iv Then, venous blood was collected at time points 0, 0.083 (intravenous injection group only), 0.25, 0.5, 1.0, 2.0, 5.0, 7.0, and 24 hours, via jugular vein or other suitable methods. Approximately 0.20 mL of blood was collected per sample, anticoagulated with heparin sodium (6.25 μL 200 mM DDVP / tube). After collection, the samples were placed on ice and centrifuged within 2 hours (centrifugation conditions: 6800g, 6 minutes, 2–8°C). Collected plasma samples were stored at -70°C before analysis. Remaining plasma samples after analysis were stored at -20°C or -70°C until LC / MS / MS analysis. Quality control sample accuracy was evaluated simultaneously with sample analysis, with over 66% of the quality control samples required to have an accuracy between 80–120%. BLQ was recorded as 0 when plotting plasma drug concentration-time curves. When calculating pharmacokinetic parameters, the concentration before administration is calculated as 0; BLQs before Cmax (including "No peak") are calculated as 0; BLQs after Cmax (including "No peak") are not included in the calculation. Using blood concentration data of brefidobacterium A at different time points, WinNonlin is used to calculate pharmacokinetic parameters such as AUC(0-t), T1 / 2, Cmax, Tmax, and MRT.
[0217] The pharmacokinetic properties of the compounds of this invention were tested using the above methods.
