Adsorption behavior and inhibitory action of benzyltriphenylphosphonium cations at the dropping mercury electrode

Adsorption behavior and inhibitory action of benzyltriphenylphosphonium cations at the dropping mercury electrode. Anastopoulos, A.; Christodoulou, A.; Jannakoudakis, D. (Lab. Phys. Chem., Univ. Thessaloniki, Thessaloniki, Greece). Z. Phys. Chem. (Wiesbaden), 137(2), 231-46 (English) 1983. CODEN: ZPCFAX. ISSN: 0044-3336. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 66, 69 The adsorption behavior of the inhibitory action of benzyltriphenylphosphonium (I) [15853-35-7] at the dropping Hg electrode in methanolic and aq. methanolic solns. of Ba(ClO4)2 were studied by a.c. and d.c. polarog. The differential capacitance data are subjected to an isotherm anal. by means of nonionic adsorption isotherms, revealing reasonable agreement with the Langmuir and Frumkin equations. From exptl. data and on the basis of the Frumkin equation a no. of adsorption parameters are derived and discussed. I is also found to present remarkable inhibitory action at the potential range from -1.15 to -1.70 V vs. SCE. This inhibitory action is indicatively examd. for the redn. of p-cyanobenzaldehyde [105-07-7] and p-chlorobenzaldehyde [104-88-1] which occurs in the adsorption potential range of I.

Polysilsesquioxanes as neoplasm inhibitors. (Tokuyama Soda Co., Ltd.Some commonly used reagents like 90819-56-0 is used in this experiment., Japan). Jpn. Kokai Tokkyo Koho JP 59020324 A2 2 Feb 1984 Showa, 10 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08G077-26; A61K031-695. APPLICATION: JP 82-128988 26 Jul 1982. DOCUMENT TYPE: Patent CA Section: 1 (Pharmacology) Section cross-reference(s): 35, 63 Polysilsesquioxanes (I; R = H or alkyl: X = CN, carbamido, carboxyl, etc.) are neoplasm inhibitors. Thus, i.p. injection of p-cyanobenzylidene-g-aminopropylpolysilsesquioxane (400 mg/kg/day for 9 days) into mice bearing Ehrlich ascites tumor increased the mean survival time 2-fold. p-Cyanobenzylidene-g-aminopropylpolysilsesquioxane was prepd. by treating g-aminopropylpolysilsesquioxane first with AcOH and then with p-cyanobenzaldehyde [105-07-7]. Formulations of tablets, capsules, and ointments contg. the polysilsesquioxanes are described. .
