In vitro spectroscopic studies of 9-amino-5-alkyl-12(H)-quino[3,4-b][1,4]benzothiazine chloride with main carrier plasma proteins.

Current methods of cancer treatment, particularly chemotherapy, are associated with harmful side effects. For this reason, it is significant to study new substances with anticancer potential with the highest possible efficacy and the lowest possible side effects. The aim of the study was the spectroscopic analysis of the interaction between 9-amino-5-alkyl-12(H)-quino[3,4-b][1,4]benzothiazine chloride (Salt3) and main carrier proteins, such as human serum albumin (HSA), α1 acid glycoprotein (AGP), human γ globulin (HGG) and controlled normal serum (CNS).
