	  abstract     = {Two new metal-based anticancer chemotherapeutic
agents, [(Ph2Sn)2(HGuO)2(phen)Cl2] 1 and [(Ph3Sn)(HGuO)(phen)]-
Cl.CH3OH.H2O 2, were designed, prepared and characterized by
analytical and spectral (IR, ESI-Mass, 1H, 13C and 119Sn NMR)
techniques. The proposed geometry of Sn(IV) in 1 and 2 is distorted
octahedral and distorted trigonal-bipyramidal, respectively. Both 1
and 2 exhibit potential cytotoxicity in vitro against MCF-7, HepG-2
and DU-145 cell lines. The intrinsic binding constant (Kb) values of 1
(2.33 × 105 M-1) and 2 (2.46 × 105 M-1) evaluated from UV-Visible
absorption studies suggest non-classical electrostatic mode of
interaction via phosphate backbone of DNA double helix. The Stern-
Volmer quenching constant (Ksv) of 1 (9.74 × 105 M-1) and 2 (2.9 ×
106 M-1) determined by fluorescence studies suggests the groove
binding and intercalation mode for 1 and 2, respectively. Effective
cleavage of pBR322 DNA is induced by 1.Their interaction with
DNA of cancer cells may account for potency.
