Marciniec, Krzysztof Pawełczak, Bartosz Latocha, Małgorzata Sułkowski, Leszek Maślankiewicz, Andrzej Maciążek-Jurczyk, Małgorzata Boryczka, Stanisław Quinolinesulfonamides: Interaction between bovine serum albumin, molecular docking analysis, and antiproliferative activity against human breast carcinoma cells <p>The complex formation of bovine serum albumin (BSA) with library of all seven regioisomeric quinolinesulfonamides (QSAs) under physiological condition is studied in this paper. The fluorescence quenching mechanism of BSA by QSAs was discussed and the association constants, as well as the number of binding sites, were calculated. In addition, a molecular docking study of the tested sulfamoylquinolines on the active site of serum albumin is performed. The experimental data and molecular docking studies reveal that sulfamoylquinolines bind in the large hydrophobic cavity of subdomain IB, and in the hydrophobic pockets of BSA subdomains IIA and IIIA by hydrophobic interactions with tryptophanyl (Trp-213) and tyrosyl residues. Moreover, the antiproliferative activity of QSAs against two human breast cancer cell lines (human adenocarcinoma (MCF-7) and human ductal carcinoma (MDA-MB-231)) and a human normal fibroblast is also studied in this paper. The antiproliferative activity of the tested QSAs was comparable to those of cisplatin. The returned data indicate that some of the tested quinolinesulfamoyl derivatives display significant cytotoxic activity.</p> Anticancer;fluorescence;molecular docking;quinolinesulfonamides;serum albumins 2017-11-21
