chromatography (HPLC). Human (h) carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA I and II and Mycobacterium tuberculosis β-CA encoded by the gene Rv3273 (mtCA 3) inhibition activity was investigated with the synthesised compounds which showed promising inhibition. The KIs were in the range of 54.6 nM-1.8 µM against hCA I, in the range of 32.1 nM-5.5 µM against hCA II and of 127 nM-2.12 µM against mtCA
