Lobaplatin is a diastereometric mixture of platinum(II) complexes containing a 1,2-bis(aminomethyl)cyclobutane stable ligand and lactic acid as the leaving group. Its antitumour activity results from the formation of DNA-drug adducts, mainly as GG and AG intra-strand cross-links.
Lobaplatin (D-19466) is a diastereometric mixture of platinum(II) complexes containing a 1,2-bis(aminomethyl)cyclobutane stable ligand and lactic acid as the leaving group. Its antitumour activity results from the formation of DNA-drug adducts, mainly as GG and AG intra-strand cross-links. Lobaplatin influences the expression of the c-myc gene, which is involved in oncogenesis, apoptosis and cell proliferation[3]. Lobaplatin and paclitaxel inhibited SGC-7901 cell growth in a concentration and timedependent manner, with IC25 values at 48h of 1.97±0.17µg/ml and 1.98±0.19 ng/ml, respectively. Lobaplatin did not affect cyclin D1 and CDK4 protein expression, while cyclin E1 and CDK2 levels were significantly increased, with cyclin B1 amounts markedly decreased (p<0.05). More S phase cells were observed after lobaplatin treatment compared with controls (60.03±1.25 vs. 18.69±0.96%; p<0.05). Lobaplatin and paclitaxel combination did not affect cyclin D1 and CDK4 protein levels (p>0.05); meanwhile, cyclin E1 and CDK2 levels were increased, with reduced cyclin B1 amounts, compared with control values (p<0.05)[4].Lobaplatin inhibited proliferation of human HCC cells in a dose-dependent manner. For the most sensitive SMMC-7721 cells, lobaplatin arrested cell cycle progression in G1 and G2/M phases time-dependently which might be associated with the down-regulation of cyclin B, CDK1, CDC25C, phosphorylated CDK1 (pCDK1), pCDK4, Rb, E2F, and pRb, and the up-regulation of p53, p21, and p27[5].Lobaplatin inhibited the proliferation of human gastric cancer cells and induced apoptosis, which may be associated with the up-regulation of Bax expression, poly(ADP-ribose) polymerase (PARP) cleavage, p53 expression and the reduction of Bcl-2 expression[6].
