1 Coumarin-benzothiazole-chlorambucil (Cou-Benz-Cbl) conjugate: an ESIPT based pH sensitive photoresponsive drug delivery system. Chlorambucil Cbl proto-oncogene Homo sapiens
2 We have developed an ESIPT based drug delivery system (DDS), Cou-Benz-Cbl conjugate, by incorporating a benzothiazole group at the 8th position of the 7-hydroxy-coumarin moiety for pH sensitive fluorescence properties and photocontrolled release of the anticancer drug chlorambucil. Chlorambucil Cbl proto-oncogene Homo sapiens
3 Photolysis of the Cou-Benz-Cbl conjugate using UV light of wavelength >=365 nm resulted in the efficient release of the anticancer drug chlorambucil. Chlorambucil Cbl proto-oncogene Homo sapiens
4 Further, an MTT assay showed that the Cou-Benz-Cbl conjugate has a good biocompatibility and low cytotoxicity towards the MDA-MB-231 cell line, whereas upon exposure to UV light, the Cou-Benz-Cbl conjugate exhibited enhanced cytotoxicity compared to the free drug due to the effective release of the anticancer drug chlorambucil inside the cancer cell.
