Design, Synthesis, Antimicrobial and Anticancer Activity of some Novel Benzoxazole-Isatin Conjugates
(2022) PV. Parvati Sai Arun
A series of novel benzoxazole-isatin conjugates were synthesized by treating 2-amino benzoxazole with 5 and 7 substituted isatin derivatives and were screened for in vitro antimicrobial and cytotoxic activities. The results showed that all the synthesized compounds shown mild to potent antibacterial activity. The MIC values were found between 10 and 100 µg/ml against tested bacterial and fungal organisms. Among all the compounds, 3d & 3c showed good antimicrobial. In vitro cytotoxic activities were evaluated by MTT assay of all the test compounds against the different human cancer cell lines. The compounds having substitution with electron-withdrawing groups (halides) at the 5th position on the isatin ring showed the most significant biological activity than substituted at the 7th position. The molecular docking interactions have shown good binding interactions with the protein targets glucosamine-6-phosphate synthase (GlcN-6-P synthase) and telomerase.
