Herein we present the design, synthesis, and biologicalevaluation of three different series of novel sulfonamides (3a-f, 6a-f and 9a-f) incorporating substituted indolin-2-one moieties (as tails) linked to benzenesulfonamide (as zinc anchoring moieties) through aminoethyl or (4-oxothiazolidin-2-ylidene)aminoethyl linkers. The synthesized sulfonamides were evaluated in vitro for their inhibitory activity

Three series of indolinone-based sulfonamides (3a-f, 6a-f and 9a-f) were in vitro evaluated as inhibitors of the tumor-associated carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA IX and XII, using a stopped-flow CO2 hydrase assay. All the investigated sulfonamides displayed single- or double-digit nanomolar inhibitory activities towards both hCA IX (K(I)s: 6.2-64.8 nM) and XII (K(I)s: 7.1-55.6 nM) isoforms. All sulfonamides (3a-f, 6a-f and 9a-f) were in vitro examined for their potential anticancer activity against colorectal cancer HCT-116 and breast cancer MCF-7 cell lines. Sulfonamide 9e was found to be the most potent counterpart against HCT-116 (IC50 = 3.67 +/- 0.33 mu M). Sulfonamide 9e displayed good selectivity profile for inhibition of the tumor-associated isoforms (CAs IX & XII) over the off-target cytosolic CAs I and II. 9e was screened for cell cycle disturbance and apoptosis induction in HCT-116 cells. It was found to persuade cell cycle arrest at G(2)-M stage as well as alter the Sub-G 1 phase. Also, 9e induced the intrinsic apoptotic mitochondrial pathway in HCT-116 cells via downregulation of the anti-apoptotic protein Bcl-2 level with concurrent boosting the pro-apoptotic Box, caspase-9, caspase-3, cytochrome C and p53 levels.
