Resistance to anticancer agents has important implications for cancer chemotherapy. Small changes in chemical structures of cytotoxic agents can alter their biological interactions that can be beneficial in overcoming the drug resistance problem. Valproic acid, a well-known antiepileptic drug is in advanced clinical studies for cancer treatment. In the present study, valproic acid was incorporated into the taxane moiety at various positions and the new analogs were evaluated for their in vitro cytotoxicity. The novel analog, Valprotaxel showed comparable cytotoxicity in head and neck, and colon cancer cell lines with remarkable improvement in selectivity for cancer cells compared to paclitaxel and docetaxel.

We report a modular approach toward novel arylazotriazole photoswitches and their photophysical characterization. Addition of lithiated TIPS-acetylene to aryldiazonium tetrafluoroborate salts gives a wide range of azoacetylenes, constituting an underexplored class of stable intermediates.In situdesilylation transiently leads to terminal arylazoacetylenes that undergo copper-catalyzed cycloadditions (CuAAC) with a diverse collection of organoazides. These include complex molecules derived from natural products or drugs, such as colchicine, taxol, tamiflu, and arachidonic acid. The arylazotriazoles display near-quantitative photoisomerization and long thermalZ-half-lives. Using the method, we introduce for the first time the design and synthesis of a diacetylene platform. It permits implementation of consecutive and diversity-oriented approaches linking two different conjugants to independently addressable acetylenes within a common photoswitchable azotriazole. This is showcased in the synthesis of several photoswitchable conjugates, with potential applications as photoPROTACs and biotin conjugates.
