In 2019,Bioorganic Chemistry included an article by Narella, Sridhar Goud; Shaik, Mohammed Ghouse; Mohammed, Arifuddin; Alvala, Mallika; Angeli, Andrea; Supuran, Claudiu T.. Formula: C8H6BrN. The article was titled 《Synthesis and biological evaluation of coumarin-1,3,4-oxadiazole hybrids as selective carbonic anhydrase IX and XII inhibitors》. The information in the text is summarized as follows:
With an aim to develop novel heterocyclic hybrids as potent anticancer agents, we synthesized a series of coumarin-1,3,4-oxadiazole hybrids (7a-t) and evaluated for their inhibitory activity against the four physiol. relevant human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms CA I, CA II, CA IX and CA XII. The CA inhibition results clearly indicated that the coumarin-1,3,4-oxadiazole derivatives (7a-t) exhibited selective inhibition of the tumor associated isoforms, CA IX and CA XII over CA I and II isoforms. Among all, compound 7b, exhibited significant inhibition in lower micromolar potency against hCA XII, with a Ki of 0.16 μM and compound 7n, exhibited significant inhibition in lower micromolar potency against hCA IX, with a Ki of 2.34 μM resp. Therefore, compound 7b and 7n could be the potential leads for development of selective anticancer agents by exhibiting a novel mechanism of action through hCA IX and XII inhibition. In the experiment, the researchers used 4-Cyanobenzyl bromide(cas: 17201-43-3Formula: C8H6BrN)
4-Cyanobenzyl bromide(cas: 17201-43-3) is used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile. It is also useful in the preparation of 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile by reaction with 2H-tetrazole in the presence of potassium hydroxide.Formula: C8H6BrN
