Applications in synthesis of triorganotin derivatives

N-Glycyl-L-tyrosine, represented as H2L-5 in a study, plays a significant role in the synthesis of new triorganotin(IV) derivatives of dipeptides with potential biomedical applications. These derivatives, such as R3Sn(HL), have been investigated for their anti-inflammatory, antimicrobial, and cardiovascular activities. The compounds were synthesized and characterized using various spectroscopic techniques. In vivo studies utilizing a carrageenan-induced paw edema bioassay in rats revealed that the triphenyltin(IV) derivatives exhibited anti-inflammatory activity comparable to phenylbutazone, a common anti-inflammatory drug, with a high safety margin. Additionally, Ph3Sn(Gly-Val) demonstrated potent cardiovascular activity. Furthermore, the compounds displayed appreciable antibacterial activities against a range of bacteria, including Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans, Microsporum gypseum, and Euglena gracilis. Notably, Ph3Sn(Gly-Gly) and Ph3Sn(Gly-Val) emerged as the most distinctive derivatives due to their promising in vivo anti-inflammatory activity and in vitro antibacterial activity against both gram-positive and gram-negative bacteria. These findings suggest the potential of N-Glycyl-L-tyrosine-based derivatives as candidates for the development of new anti-inflammatory, antimicrobial, and cardiovascular agents. ²
