Plutella xylostella cause considerable harm to the production of broccoli, Chinese cabbage, cabbage and cauliflower. The control P. is mainly performed using commercial insecticides, which have even led emergence resistant populations. Two easily available natural products found in different plants essential oil, thymol eugenol, stand up as possible novel agents this pest. In work a series alky...

www.thelancet.com Vol 384 October 11, 2014 1345 as 1–2% chlorhexidine in isopropyl alcohol, but we agree with Maiwald and colleagues that adequate studies to support or reject this hypothesis have not yet been done. Chlorhexidine in an alcoholic solution, however, is clearly superior to povidone-iodine for prevention of vascular catheter-related bloodstream infec tion. Maiwald and colleagues ha...

(1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (R)-4-methylbenzenesulfonimidate was synthesized via the stereoselective NH-transfer to (S)-4-methylbenzenesulfinate. The reaction employed diacetoxyiodobenzene (DIB) and ammonium carbamate, occurred in acetonitrile at room temperature. imidation of sulfur proceeded with complete stereocontrol, afforded desired product as a single diastereoisomer high e...

In a 4-isopropyl-1-oxa-3-oxonia-2-borata-naphthalene the isopropyl group exhibits the same conformational phenomena as the Me2N group in 8-dimethylamino-naphth-1-yl-silanes and related phosphorus compounds. Since the details can be fully rationalized on the basis of the steric situation and electronic factors are excluded, the common features cannot serve to infer dative interaction from nitrog...

Several mouse aldehyde dehydrogenases catalyze the detoxification of aldophosphamide, the pivotal metabolite of the prodrugs cyclophosphamide, mafosfamide, and other oxazaphosphorines. N-Isopropyl-p-formylbenzamide, a major metabolite of procarbazine, was found to be an excellent substrate (Km = 0.84 microM) for at least one of these enzymes, namely, mouse aldehyde dehydrogenase-2. The Km for m...
