Protoxylogranatin B, a Key Biosynthetic Intermediate from Xylocarpus granatum: Suggesting an Oxidative Cleavage Biogenetic Pathway to Limonoid
نویسندگان
چکیده
Protoxylogranatin B, a new protolimonoid identified from the seeds of a Chinese mangrove, Xylocarpus granatum, was proposed as the key biosynthetic intermediate. Its structure was established on the basis of spectroscopic techniques, including 1 H– 1 H COSY, HSQC, HMBC and NOESY spectra. The finding of this compound suggested an oxidative cleavage biogenetic pathway from protolimonoid to limonoid.

Novel and Neuroprotective Tetranortriterpenoids from Chinese Mangrove Xylocarpus granatum Koenig
Eight new tetranortriterpenoids (1-8) were isolated from the twigs and leaves of the Chinese mangrove plant Xylocarpus granatum, together with four related known ones (9-12). The structures of new compounds were elucidated by detailed spectroscopic analysis. The absolute configuration of 9-epixylogranatin A (1) was determined by time-dependent density functional theory-electronic circular dichr...
متن کاملIsolation of three marine prostanoids, possible biosynthetic intermediates for clavulones, from the Okinawan soft coral Clavularia viridis.
Three marine prostanoids, 1, 2, and 3, were isolated from the extract of the Okinawan soft coral Clavularia viridis. The structures of these compounds were assigned based on the results of spectroscopic analysis. Compound 1 was shown to be preclavulone-A methyl ester, and this is the first isolation of the ester of preclavulone-A as a natural product. Preclavulone-A is proposed to be the key in...
متن کاملValidating an endoperoxide as a key intermediate in the biosynthesis of elysiapyrones.
Compounds 1-3 isolated from Elysia diomedea are described. Compound 1 is an endoperoxide derivative of elysiapyrone A. The biomimetic-type transformation of compound 1 to elysiapyrone A catalyzed by neutral base transformed the endoperoxide to a vicinal diepoxide, thus suggesting the endoperoxide as a key intermediate in the biosynthesis of elysiapyrone A. A biogenetic pathway for their formati...

Diarrhoea is a common disease which causes pain and may be deadly, especially in developing countries. In Bangladesh, diarrhoeal diseases affect thousands of people every year, and children are especially vulnerable. Bacterial toxins or viral infections are the most common cause of the disease. The diarrhoea outbreaks are often associated with flood affected areas with contaminated drinking wat...
