A series of 4-(thiazol-2-ylamino)-benzenesulfonamides was synthesized and screened for their carbonic anhydrase (CA, EC 4.2.1.1) inhibitory and cytotoxic activity on human breast cancer cell line MCF-7. Human (h) CA isoforms I, II and IX were included in the study. The new sulfonamides showed excellent inhibition of all three isoforms, with KIs in the range of 0.84-702 nM against hCA I, of 0.41-288 nM against hCA II and of 5.6-29.2 against the tumor-associated hCA IX, a validated anti-tumor target, with a sulfonamide (SLC-0111) in Phase I clinical trials for the treatment of hypoxic, metastatic solid tumors overexpressing CA IX. The new compounds showed micromolar inhibition of growth efficacy against breast cancer MCF-7 cell lines.

Synthesis and cytotoxic activity in the submicromolar range of a series of [4-(imidazol-1-yl)thiazol-2-yl]-phenylamines are described. Cell cycle dependent cytotoxicity on RKO human colon carcinoma cells with inducible expression of p27kip1 and the influence on microtubule formation were investigated. Considering the significant correlation between the IC50 values of tubulin polymerization inhibition, [3H]colchicine competition, and cytotoxicity of the investigated compounds, tubulin is the main cellular target. The inhibition of microtubule formation was shown to be mediated by interference with the colchicine binding site of tubulin. In depth analysis of the investigated compounds allowed the identification of modifications that altered the pharmacological profile of the compounds from a mitosis-inducing phenotype to a G1 cell cycle arresting phenotype.
