- Antitumor activity of some amino acid metal systems
- Antitumor activity of some amino acid metal systems. Banner, R. J.; Charlson, A. J.; Gale, R. P.; McArdle, N. T.; Trainor, K. E.; Watton, E. C. (Sch. Chem., Macquarie Univ., North Ryde, Aust.). Cancer Treat. Rep., 61(3), 469-70 (English) 1977. CODEN: CTRRDO. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacodynamics) L-glutamine-K tetrochloroplatinate (II) complex, L-glutamine-K tetrachloropalladate(II) complex, L-serine-K tetrachloroplatinate (II) complex, and glycine-K tetrachloroplatinate (II) complex, showed antileukemic activity in mice, but K tetrachloroplatinate (II) [10025-99-7] and K tetrachloropalladate [10025-98-6] were ineffective. Apparently, the antitumor activity is produced by the complex species formed from the amino acids and the metal salts.
- Inactivation of dihydropteridine reductase (human brain) by platinum(II) complexes
- Inactivation of dihydropteridine reductase (human brain) by platinum(II) complexes. Armarego, Wilfred L. F.; Ohnishi, Akiko (John Curtin Sch. Med. Res., Aust. Natl.Some commonly used reagents like 16941-12-1 and 14096-51-6 are used in this experiment. Univ., Canberra 2601, Australia). Eur. J. Biochem., 164(2), 403-9 (English) 1987. CODEN: EJBCAI. ISSN: 0014-2956. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 7 Potassium tetrachloroplatinate (K2PtCl4) [10025-99-7] inactivates dihydropteridine reductase (EC 1.6.99.7) [9074-11-7] from human brain in a time-dependent and irreversible manner. The inactivation has been followed by measuring enzyme activity and fluorescence changes. The enzyme is completely protected from inactivation by NADH, the pterin cofactor [quinonoid 6-methyl-7,8-dihydro(6H)pterin] and dithiothreitol. Evidence is presented that K2PtCl4 reacts at the active site and that (a) thiol group(s) is involved in, or is masked by this reaction. K2PtCl4 is a stronger inhibitor of human brain dihydropteridine reductase than cis- [15663-27-1] and trans-diaminodichloroplatinum [14913-33-8], cis-dichloro[ethylenediamine]platinum [14096-51-6] and K4Fe(CN)6, whereas H2PtCl6 is considerably weaker and (Ph3P)3RhCl is inactive. .
