Pesticide composition.Chemical with cas number 63048-48-6 also plays role. Beriger, Ernst (Ciba-Geigy A.-G., Switz.). Ger. Offen. DE 2643476 7 Apr 1977, 27 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07D309-36. PRIORITY: CH 75-12589 29 Sep 1975. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 27 I (R3 and R4 each = H, halogen, Me, CF3, CN, or NO2; R5 = H, Cl, CF3) are insecticides. Thus, 0.05% (from a 10% emulsion conc.) 3-[[4-(trifluoromethyl)phenyl]carbamoyl]-4-hydroxycoumarin [63048-17-9] prepd. by reacting 4-hydroxycoumarin [1076-38-6] with 4-(trifluoromethyl)phenyl isocyanate [1548-13-6] effectively controlled Leptinotarsa decemlineata larvae on potato plants. The synthesis and formulation of I is given. .

Enzyme induction by coumarins

Enzyme induction by coumarins. Ritschel, W. A.; Lee, Li-Hwa (Coll. Pharm., Univ. Cincinnati Med. Cent., Cincinnati, Ohio, USA). Drug. Dev. Ind. Pharm., 3(5), 401-16 (English) 1977. CODEN: DDIPD8. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacodynamics) The Na pentobarbital sleeping time in mice was studied after pretreatment with coumarins (coumarin (I) [91-64-5], 4-hydroxycoumarin [1076-38-6], 7-hydroxycoumarin [93-35-6], acenocoumarol [152-72-7], bis-hydroxycoumarin [66-76-2], phenprocoumon [435-97-2] and Na warfarin [129-06-6]). All coumarins except bishydroxycoumarin caused a statistical significant redn. of barbiturate sleeping time, hence, have to be considered as enzyme-inducers. The largest enzyme inducing effect was obsd. with warfarin.
