Biochem/physiol Actions

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.

Platinum-based chemotherapy is recommended as the first-line treatment regimen for patients with advanced non-small-cell lung cancer (NSCLC). Lobaplatin (LBP), a third-generation platinum anti-neoplastic agent, has shown an improved efficacy. This study is aimed to investigate the mechanisms of LBP-induced apoptosis

Lobaplatin [1,2-diamminomethylcyclobutane-platinum(II) lactate] is a new platinum compound with interesting preclinical activity and apparently no nephro- or neurotoxicity that is currently undergoing clinical phase II studies. Little is known about the cross-resistance between cisplatin and lobaplatin. The activity of this
