Phosphonium compounds as new and specific inhibitors of bovine serum amine oxidase

Phosphonium compounds as new and specific inhibitors of bovine serum amine oxidase. Di Paolo, Maria Luisa; Lunelli, Michele; Scarpa, Marina; Rigo, Adelio ( Dipartimento di Chimica Biologica, Universita di Padova, Padua 35121, Italy). Biochemical Journal, 384(3), 551-558 (English) 2004 Portland Press Ltd. CODEN: BIJOAK. ISSN: 0264-6021. DOCUMENT TYPE: Journal CA Section: 7 (Enzymes) TPP+ (tetraphenylphosphonium ion) and its analogs were found to act as powerful competitive inhibitors of BSAO (bovine serum amine oxidase). The binding of this new class of inhibitors to BSAO was characterized by kinetic measurements. TPP+ can bind to the BSAO active site by hydrophobic and by Colombian interactions. The binding probably occurs in the region of the cation-binding site. Under physiol. conditions, the assocn. const. of TPP+ for this site is higher than 106 M-1, the change of enthalpy being the main free-energy term controlling binding. Anal. of the relationships between substrate structure and extent of inhibition by TPP+ reveals some new mol. features of the BSAO active site.Except for chemicals metioned above, 1031-15-8 and 75-57-0 are also used. .

Carboxylic acid anhydrides. Gallucci, Jacques; Gauthier-Lafaye, Jean; Leconte, Philippe; Perron, Robert (Rhone-Poulenc Chimie de Base, Fr.). Eur. Pat. Appl. EP 89908 A1 28 Sep 1983, 28 pp. DESIGNATED STATES: R: AT, BE, CH, DE, FR, GB, IT, LI, LU, NL, SE. (French). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C07C051-56; C07C053-12. APPLICATION: EP 83-420052 22 Mar 1983. PRIORITY: FR 82-5268 23 Mar 1982. 127-09-3 and 1031-15-8 which are cas registry numbers of chemicals are mentioned. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Alkyl iodides (and alkyl alkanesulfonates and arenesulfonates) were treated with CO and alkali, alk. earth, quaternary ammonium, quaternary phosphonium, dipos. manganese, zinc, lanthanide, and actinide salts of alkanoic acids, PhCO2H, and phenylalkanoic acids and salts of HCo(CO)4 to yield RC(O)OC(O)R1 (R = alkyl and R1 = same or different alkyl, Ph, phenylalkyl). Thus, MeI was treated with CO, MeP+Ph3 OAc-, and Li+ [Co(CO)4]- to give Ac2O. .
