P. Carpinelli et al., SYNTHESIS AND BIOLOGICAL-ACTIVITY OF 5-COORDINATE PLATINUM(II) COMPLEXES INCLUDING ORGANOTIN FRAGMENTS, Anti-cancer drug design, 10(1), 1995, pp. 43-49
The synthesis and characterization of two five-coordinate platinum(II)
complexes of general formula [PtCl(SnMe(n)Cl3-n)(2,9-Me2-1,l0-phenant
hroline) (diethylfumarate)] (n = 1, 2) are described. The bimetallic s
pecies were tested on the neuroblastoma cell line SK-N-BE and a consid
erable inhibition of cellular proliferation was detected; the bimetall
ic species were also able to induce neuronal differentiation, as did r
etinoic acid, a well-known neuroblastoma differentiating agent.
