Although most of the menthol used today still come from certain natural sources such as the peppermint oil (derived from Mentha arvensis), synthetic products of accepted quality have recently become a commodity of considerable quantity. The starting materials used for the synthesis of menthol have ...
Tropane alkaloids from nightshade plants are neurotransmitter inhibitors that are used for treating neuromuscular disorders and are classified as essential medicines by the World Health Organization1,2. Challenges in global supplies have resulted in frequent shortages of these drugs3,4. Further vulnerabiliti...
Biosynthesis of the Nicotiana alkaloids. 来自 ResearchGate 喜欢 0 阅读量: 22 作者: R. F. DAWSON 摘要: The development of eight-node arbitrary quadrilateral membrane elements with drilling degrees of freedom is presented using the compatible displacement interpolation within the element. The element is...
In C. roseus cell suspension culture, CK enhances the accumulation of alkaloids17, whereas auxin negatively regulates the expression of key TIA biosynthesis genes, including TRYPTOPHAN DECARBOXYLASE (TDC) and STR18,19. However, the molecular mechanism of auxin-mediated regulation of the TIA pathway ...

The ergots are a structurally diverse group of alkaloids derived from tryptophan and dimethylallyl pyrophosphate (DMAPP) . The potent bioactivity of ergot alkaloids have resulted in their use in many applications throughout human history. In this highlig
Part X. Terminal Steps in the Biosynthesis of the Morphine Alkaloids [2-3H]Morphine has been prepared and the stability of its label under a variety of conditions has been studied. The morphine has been converted into [2-3H]codeine and [2-3H]codeinone and the former has been used with ...

The biosynthesis of the ergot alkaloids The physiological activity of complete series of mono- and di-substituted chloro-and methyl-phenoxyacetic and benzoic acids have been investigated using the wheat cylinder, pea segment and pea curvature tests. In the phenoxyacetic acids,... AJ Birch,BJ Mc...
DR. W. O. JAMES, in his interesting paper on “Biosynthesis of the Belladonna Alkaloids”1, states that the embryos and endosperms of the resting seeds of Atropa and Datura are without alkaloids, but that the latter appear at an early stage of germinatio
