Sulfabenzamide (Sultrin, N-Sulfanilylbenzamide) is an antibacterial/antimicrobial which also exhibit their antitumor effects through multiple mechanisms including inhibition of membrane bound carbonic anhydrases, prevention of microtubule assembly, cell cycle arrest, and inhibition of angiogenesis.
Sulfabenzamide inhibits the proliferation and increases Caspase-3 activity in T-47D cells. It dose not induce apoptosis but a minimal shift from G1 to S and G2/M phases of the cell cycle[1].
