Abstract:
The complexes [Pt(bah)2X2], [Pt(NH3)(bah)Cl2].0.5H2O, [Pt(mbah)2X2], and [Pt(NH3)(mbah)Cl2] (bah = benzoic acid hydrazide, mbah = 3-methoxybenzoic acid hydrazide; X = Cl, Br, I) have been prepared and characterized by elemental analysis, electric conductivity, IR, 1H NMR, and electronic spectra. A cis-square planar structure with hydrazide ligands coordinated via the NH2-groups has been proposed for these complexes. The complexes have shown a growth-inhibitory effect against Friend leukemia cells in culture comparable to that of the antitumor drug cisplatin.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
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...
