The reaction of A8-tetrahydrocannabinol with aor p-glucose penta-acetate gave a novel product considered to be 2-(/3-tetra-acetylglucosyl)-A8-tetrahydrocannabinol.
The synthesis of Pyoluteorin, an antibiotic from Pseudomonas aeruginosa is described. The method used produced in addition, an isomer 3,5-dichloro-2-(2',6'-dihydroxybenzoyl)pyrrole, for which the name isopyolrrteoritt is proposed. The bromine analogue of pyoluteorin is also reported.
THE phenoxazone nucleus (I) is widespread inNature :1 some wood-rotting fungi contain cinnabarin (11) and/or cinnabaric acid (III),a and phenoloxidases of the laccase type are thought to play a role in the biosynthesis of actinomycins by Streptomyces species.3 The oxidation of some 0aminophenols catalysed by a laccase obtained from the wood-rotting fungus Polyporus versicololA has now been investigated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
