Notes de l'éditeur
- While studying electric fields and growth of E. Coli/// Rosenberg 1964 Group VIIIb transition metal compounds inhibit cell division 1-10ppm Growth not affected Components of the experimental medium were electrolyzed and tested for the presence of oxidizing agents by reacting with KI/starch solutions. Positive results were found for NH4Cl. NH4)2PtCl6 was formed to be the active agent.
- the trans effect is the labilization of ligands trans to certain other ligands, which can thus be regarded as trans directing ligands.

- Preformed Pt- HSA (human serum albumin) administered clinically to patients there was increased survival time. Individuals with low HSA did not respond well to cisplatin Centerwall at Syracuse found using HSQC NMR N15 NMR-h1
- Carboplatin cyclobutane dicarboxylate decreases reactivity. Oxaliplatin for colon cancer…oxalate increases water solubility…othermechanisms unknown
- Many insecticides show cross resistance Increased reactivity with glutathione may reduce cytotoxicity
- Lead compound in future studies of Pt. compounds with hydrophobic ligands. They speculate that the structure of water molecules around adamantineamine affect reaction with glutathione and thiols.
