Isocoumarin Thioanalogues as Potential Antibacterial Agents
摘要:
A series of 3-substituted-1H-isochromene-1-thiones (3) were prepared by the reaction of 3-substituted isocoumarins (2) with Lawesson's reagent in the presence of toluene under a nitrogen atmosphere. The antimicrobial activities of the newly synthesized products were measured using Gram-negative (Escherichia coli, Salmonella typhi, and Proteus mirabilis) and Gram-positive bacteria (Staphylococcus aureus and Bacillus cereus). Synthesized thioanalogue of isocoumarins showed good antibacterial activity against Proteus mirabilis.

A series of 1H-isochromen-1-one derivatives and their thio analogues were synthesized by thionation using Lawesson's reagent for evaluation of their cytotoxic effect on cancer cells. The effect of these derivatives was tested on the growth of human epidermoid carcinoma A431 cell line by MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide] colorimetric assay. MTT assay revealed that these new compounds are potent inhibitors of cell growth. Supplemental materials are available for this article.
