Abstract

Hypoxia in tumors contributes to chemotherapy resistance, worsened by acidosis driven by carbonic anhydrases (hCA IX and XII). Targeting these Enzymes can mitigate acidosis, thus enhancing tumor sensitivity to cytotoxic drugs. Herein, novel 4-(pyrazolyl)benzenesulfonamide ureas (SH7a-t) were developed and evaluated for their inhibitory activity against hCA IX and XII. They showed promising results (hCA IX: KI = 15.9-67.6 nM, hCA XII: KI = 16.7-65.7 nM). Particularly, SH7s demonstrated outstanding activity (KIs = 15.9 nM for hCA IX and 55.2 nM for hCA XII) and minimal off-target kinase inhibition over a panel of 258 kinases. In NCI Anticancer screening, SH7s exhibited broad-spectrum activity with an effective growth inhibition full panel GI50 (MG-MID) value of 3.5 μM and a subpanel GI50 (MG-MID) range of 2.4-6.3 μM. Furthermore, SH7s enhanced the efficacy of Taxol and 5-fluorouracil in cotreatment regimens under hypoxic conditions in HCT-116 colorectal Cancer cells, indicating its potential as a promising Anticancer agent.
