New Ruthenium complexes with antitumoral activity

Synthesis, Structural characterization and Exafs investigations of new ruthenium(III) complexes.

Two new complexs of Ru(III) with glucosaminic acid and 1-Methyluracil, [RuCl2(Glun-N,O)2]H (I), (Glun-= glucosaminate); [RuCl4(1-MeU-N3)(DMSO)]H2.H2O (II), (1-MeU-= 1-Methyluracilate) were prepared from the same Ru(III) precursors, RuCl3•3H2O and [(DMSO)2H][trans-RuCl4(DMSO)2]. The characterization of the complexes have been carried out by elemental analysis, FT-IR, ES-MS, NMR and EXAFS.

Diorganotin(IV) N-acetyl-L-cysteinate complexes: synthesis, solid state, solution phase, DFT and biological investigations.

Diorganotin(IV) complexes of N-acetyl-L-cysteine (H(2)NAC; (R)-2-acetamido-3-sulfanylpropanoic acid) have been synthesized and their solid and solution-phase structural configurations investigated by FTIR, Mössbauer, (1)H, (13)C and (119)Sn NMR spectroscopy. FTIR results suggested that in R(2)Sn(IV)NAC (R = Me, Bu, Ph) complexes NAC(2-) behaves as dianionic tridentate ligand coordinating the tin(IV) atom, through ester-type carboxylate, acetate carbonyl oxygen atom and the deprotonated thiolate group. From (119)Sn Mössbauer spectroscopy it could be inferred that the tin atom is pentacoordinated, with equatorial R(2)Sn(IV) trigonal bipyramidal configuration. In DMSO-d(6) solution, NMR spectr…

ORGANOSTAGNO(IV) COMPLESSI CON N-ACETILCISTEINA AD ATTIVITÀ ANTITUMORALE, PROCEDIMENTO PER LA LORO PRODUZIONE E LORO USO.

Organotin(IV) and simple fatty acids: preliminary assessments

Our group has a long researching tradition in the field of organotin(IV) complexes, usually proposed and tested as potential anti-tumor drugs. The leitmotif has usually been the modulation of the intrinsic toxicity/cytotoxicity of the organometallic moiety and a modulation of the toxic effect by means of biologically related molecules (synthetic or natural). Such a modulation is usually achieved by two (often overlapping) routes: dampen the damaging effects of the metal core, and serving as a carrier for specific tissue districts. Since a too tight binding on the organotin moiety is not always desirable – a too much stable complex could be a non-active one – carboxylates have always played …

Synthesis, chemical characterization and biological activity of new histone acetylation/deacetylation specific inhibitors: a novel and potential approach to cancer therapy

Three new triorganotin(IV) complexes of valproic acid (vp1, Me3Sn-valproate; vp2, Bu3Sn-valproate; vp3, Ph3Sn-valproate) have been synthesized and investigated by spectroscopic and biological methods. An anionic, monodentate valproate ligand was observed, ester-like coordinating the tin atom on a tetra-coordinated, monomeric environment. The structures, though, can distort towards a penta-coordination, as a consequence of a long range O center dot center dot center dot Sn interaction. Crystallographic and NMR findings confirm this situation both in solid state and solution. Biological finding evidenced a clear cytotoxic action of the complexes in hepatocellular carcinoma cell cultures: one …
