Nicotinate esters: their binding to and hydrolysis by human serum albumin.
Nicotinate esters were studied for their binding to, and hydrolysis by, human serum albumin. Some esters (ethyl, isopropyl, t-butyl, cyclohexyl, benzyl) were bound but not hydrolysed, while others (2-chloroethyl, 2-butoxyethyl) displayed the opposite behaviour; 1-carbamoylethyl ester was neither bound nor readily hydrolysed. Only p-methoxyphenyl nicotinate was both a ligand and a substrate, and its rate constants of binding and hydrolysis were calculated in a stepwise procedure using a kinetic model.
