Sulfonamides 47-59 carbonic anhydrase 5A Homo sapiens 400-404 21300547-2 2011 The new sulfonamides selectively inhibited the mitochondrial isozymes hCA VA and VB (h=human isoform) over the cytosolic, off-target ones hCA I and II, with inhibition constants in the low nanomolar range. Sulfonamides 8-20 carbonic anhydrase 5A Homo sapiens 70-83 11140614-4 2000 The mechanism of antitumor action with these sulfonamides is unknown, but it might involve either inhibition of several CA isozymes (such as CA IX, CA XII, CA XIV) predominantly present in tumor cells, a reduced provision of bicarbonate for the nucleotide synthesis (mediated by carbamoyl phosphate synthetase II), the acidification of the intracellular milieu as a consequence of CA inhibition or uncoupling of mitochondria and potent CA V inhibition among others. Sulfonamides 45-57 carbonic anhydrase 5A Homo sapiens 436-440 11203012-3 2000 The mechanism of antitumour action with the new sulfonamides reported here is unknown, but it might involve either inhibition of several CA isozymes (such as CA IX, CA XII, CA XIV) present predominantly in tumour cell membranes, acidification of the intracellular environment as a consequence of CA inhibition, uncoupling of mitochondria and/or strong CA V inhibition, or a combination of several such mechanisms.
