Abstract
Herein we report for the first time a series of 2-benzamido-N-(2-oxo-4-(methyl/trifluoromethyl)-2H-chromen-7-yl) benzamide 3a-f and substituted quinazolin-4(3H)-ones and 2H-benzo[e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxides (5, 6, 8 and 10a-c) as selective inhibitors of the tumor associated hCA IX and XII isoforms. Among the compounds reported the trifluoromethyl derivative 3d resulted the most potent against these CA isoforms with KIs of 10.9 and 6.7nM.
Keywords:
2H-Benzo[e][1,2,4]thiadiazine 1,1-dioxides; Carbonic anhydrase inhibitors (CAIs); Coumarins; Hypoxic tumors; Quinazolines.
