Relations between fungicidal effect on Diaporthe citri and effect on mitochondrial respiration of 8-quinolinol and its related compounds. Tomono, Kohtaro; Kumazawa, Noriyuki (Dev. Res. Dep., Tomono Nohyaku Co., Shizuoka 420, Japan). Nippon Noyaku Gakkaishi, 9(4), 759-62 (English) 1984. CODEN: NNGADV. ISSN: 0385-1559. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Respiration by rat liver mitochondria was accelerated by 10-3-10-2 M quinoline [91-22-5] and 6- [580-16-5], 7- [580-20-1], and 8-quinolinol [148-24-3], 10-3-10-4 M a-naphthol [90-15-3], 10-5-10-4M 5-chloro-7-bromo-8-quinolinol [7640-33-7], and 10-5-2 ′ 10-4 M 5,7-dibromo- [521-74-4] and 5,7-dichloro-8-quinolinol [773-76-2]. These compds. inhibited pycnospore germination of D. citri at concns. similar to those accelerating rat liver mitochondrial respiration, a close correlation being found between log 1/I50 and log 1/C1.5 where I50 was the 50% inhibitory concn. of these compds. toward pycnospore germination of D. citri and C1.5 was the concn. causing 50% increase in the respiratory rate of rat liver mitochondria. 2-Quinolinol had no effect on the respiration, and 4- [611-36-9] and 5-quinolinol [578-67-6] slightly inhibited the respiration at 10-3-10-2 M.

Thermoanalytical investigations on heterocyclic organic compounds. Part III. The effect of introducing a ring nitrogen atom on the function of 1-naphthol as antioxidant. A differential scanning calorimetric study. Barbooti, Mahmood M.; Al-Sammerrai, Dhoaib A. (Sol. Energy Res. Cent., Sci. Res. Counc., Baghdad, Iraq). Thermochim. Acta, 76(1-2), 221-8 (English) 1984. CODEN: THACAS. ISSN: 0040-6031. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) The introduction of a ring N atom into the arom. skeleton of 1-naphthol (I) [90-15-3] affects its function as an additive in inhibiting oxidn. in a lubricating oil. I with a Ni atom in the 2 and 8 positions (1-hydroxyisoquinoline [491-30-5] and 8-hydroxyquinoline [148-24-3]) exhibited weak antioxidant activity, whereas the derivs. with the N atom in the 5 and 6 positions (5-hydroxyquinoline [578-67-6] and 5-hydroxyisoquinoline [2439-04-5]) had activity comparable to that of I. The systems were also studied in the presence of sol. metal oxidn. catalysts. Explanations are given based on the stability of phenoxy radicals and the coordination ability of the species.
