文摘
Human thymidylate synthase (hTS) was targeted through a virtual screening approach. The most optimal inhibitor identified, 2-{4-hydroxy-2-[(2-hydroxybenzylidene)hydrazono]-2,5-dihydrothiazol-5-yl}-N-(3-trifluoromethylphenyl)acetamide (5), showed a mixed-type inhibition pattern, with a Ki of 1.3 渭M and activity against ovarian cancer cell lines with the same potency as cisplatin. X-ray studies revealed that it binds the inactive enzyme conformation. This study is the first example of a nonpeptidic inhibitor that binds the inactive hTS and exhibits anticancer activity against ovarian cancer cells.
