A series of quinoline-uracil hybrids has been rationalized and synthesized. The inhibitory activity against hCA isoforms I, II, IX, and XII was explored. Compoundsmonstrated powerful inhibitory activity against all tested hCA isoforms. Compound (E)-6-Amino-5-(((6-methoxy-2-oxo-1,2-dihydroquinolin-3-yl)methylene)amino) pyrimidine-2,4(1H,3H)-dione displayed the best selectivity profile with good activity. Compound (E)-6-Amino-1-methyl-5-(((2-oxo-1,2-dihydroquinolin-3-yl)methylene)amino) pyrimidine-2,4(1H,3H)-dione displayed the best activity profile with minimal selectivity. Compound (E)-3-(((6-Amino-1-methyl-4-oxo-2-thioxo-1,2,3,4-tetrahydropyrimidin-5yl)imino)methyl)-6-methoxyquinolin-2(1H)-one emerged as the best congener considering both activity (IC50 = 140 and 190 nM for hCA IX and hCA XII, resp.) and selectivity (S.I. = 13.20 and 9.75 for II/IX, and II/XII, resp.). The most active hybrids were assayed for antiproliferative and pro-apoptotic activities against MCF-7 and A549. In silico studies, mol. docking, physicochem. parameters, and ADMET anal. were performed to explain the acquired CA inhibitory action of all hybrids. A study of the structure-activity relationship revealed that bulky substituents at uracil N-1 were unfavored for activity while substituted quinoline and thiouracil were effective for selectivity.
Pharmaceuticals published new progress about Antitumor agents. 598-50-5 belongs to class isoquinoline, name is 1-Methylurea, and the molecular formula is C2H6N2O, Application of 1-Methylurea.
