The complex-formation equilibria of [Pd(SMC)(H2O)2]+, where SMC = S-methyl-l-cysteinate, with bio-relevant ligands such as amino acids, peptides, dicarboxylic acids and DNA constituents were studied and their formation constants were determined. The binding mode of the ligands containing various functional groups

Several disulfide-reducing agents, such as dithiothreitol, 2,3-dimercapto-1-propanol, cysteine ethyl ester, and cysteine methyl ester enhanced the effectiveness of 1-methyladenine (1-MeAde) to induce oocyte maturation in the starfish Asterina pectinifera. This enhancement occurred at relatively low concentrations at which these agents
