Site-Specific Binding of Anti-Cancer Drugs to Human Serum Albumin

The interaction of drugs with proteins plays a very important role in the distribution of the drug. Human serum albumin (HSA) is the most abundant protein in the human body, showing great binding characteristics, and has gained a lot of importance pharmaceutically. It plays an essential role in the pharmacokinetics of a number of drugs; hence, several reports are available on the interaction of drugs with HSA. It can bind to cancer drugs; thus, it is crucial to look at the binding characteristics of these drugs with HSA. Herein, we summarize the binding properties of some anti-cancer drugs by specifically looking into the binding site with HSA. The number of drugs binding at the Sudlow's site I situated in subdomain II A is more than the drugs binding at Sudlow's site II.
