Activation-independent cyclization of monoterpenoids.
The biosynthesis of cyclic monoterpenes (C(10)) generally requires the cyclization of an activated linear precursor (geranyldiphosphate) by specific terpene cyclases. Cyclic triterpenes (C(30)), on the other hand, originate from the linear precursor squalene by the action of squalene-hopene cyclases (SHCs) or oxidosqualene cyclases (OSCs). Here, we report a novel terpene cyclase from Zymomonas ...
متن کاملMonoterpenoids from Acanthopanax sessiliflorus fruits.
Three new acyclic monoterpenoids named (2E)-3,7-dimethylocta-2,6-dienoate-6-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (1), (3Z,6E)-3,7-dimethyl-3,6-octadiene-1,2,8-triol (2) and (6E)-7-methyl-3-methylene-6-octene-1,2,8-triol (3) were isolated from Acanthopanax sessiliflorus fruits, along with three known monoterpenoid compounds. The structures of the new compounds were determined by mean...
متن کاملMonoterpenoids and tetralin as pediculocides.
Sir, The increasing resistance of head lice to established insecticides means that patients and parents are seeking alternative effective treatments (1). Essential oils, including tea tree oil and Biz Niz, are promoted as treatments for head lice by alternative medicine therapists. Tea tree oil is the essential oil steam distilled from the leaves and terminal branches of tea trees, in particula...
متن کاملBiotransformation of Monoterpenoids by Suspension Cultures of Lavandula angustifolia
Callus and suspension cultures of Lavandula angustifolia Mill. (Lamiaceae) were established and the effect of different culture media on growth rate was investigated. Terpenoids added to suspension culture to investigate their biotrans-formation. All samples were analyzed by gas chromatography (GC) and GC-mass spectroscopy (MS). Octan-1-ol, citronellol, linalool, borneol and geran...
متن کاملInteractions of Avocado (Persea americana) Cytochrome P-450 with Monoterpenoids.
The microsomal fraction of avocado (Persea americana) mesocarp is a rich source of cytochrome P-450 active in the demethylation of xenobiotics. Cytochrome P-450 from this tissue has been purified and well characterized at the molecular level (DP O'Keefe, KJ Leto [1989] Plant Physiol 89: 1141-1149; KR Bozak, H Yu, R Sirevag, RE Christoffersen [1990] Proc Natl Acad Sci USA 87: 3904-3908). Despite...
