Abstract:
Seven new iodo-bridged binuclear platinum(II) complexes [Pt(L)I2]2 (1-7) (L=n-butylamine, isopropylamine, m-toluidine, p-toluidine, diethylamine, N-methylaniline and aniline) have been synthesized and characterized by elemental analysis, conductivity, thermal analysis, IR, 1H NMR and mass spectra techniques. The cytotoxicity was tested by MTT assay. The results indicate that they have selectivity against tested carcinoma cell lines. For example, the complexes (3 and 7) have better cytotoxicity than cisplatin against Bel-7402 cell line, the complexes (2-5 and 7) have better cytotoxicity than cisplatin against Hela cell line. The results suggest that the species of amine has important effect on cytotoxicity, when L=m-toluidine, p-toluidine and aniline, the complexes have better cytotoxicity against tested carcinoma cell lines.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Phase II Reactions: Miscellaneous Conjugation Reactions
A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate. The production of...
