Biological Activity
Lobaplatin (D-19466) is a third-generation platinum anticancer agent in vitro and in vivo, consisting of ~50:50 mixture of the two trans-1,2-cyclobutanedimethanamine diastereomers in complex with L-lactic acid. Llobaplatin shows antitumor efficacy against various human cancer cancer xenografts and significantly prolongs the survival of mice bearing P388 leukemia (mean life span increase post single i.p. in mg/kg = 46%/4.64 & 77/14.7). Compared to first and second generation platinum compounds, lobaplatin appears to be more stable, less toxic, have a better therapeutic index and may overcome tumor resistance.
