Abstract:
The plant Murraya koenigii, commonly known as curry leaf tree is a rich source of carbazole alkaloids. A number of monomeric as well as dimeric carbazoles with C13, C18 and C23 skeleton have been isolated from the plant. In my present work, a new carbazole alkaloid, designated as mumunine, was isolated from the bark of Murraya koenigii (Linn) Spreng, along with a known carbazole alkaloid, viz. mahanimbine. The structure of the new alkaloid 1 was elucidated on the basis of 1D and 2D NMR spectral data analysis. In this paper, the isolation and structure elucidation of the new compound will be di

Abstract:
The stem bark of Glycosmis mauritiana contained the acridone alkaloids noracronycine and des-N- methylacronycine, and two new carbazole alkaloids, 3,3,10-trimethyl-3,7-dihydropyrano[2,3-c] carbazole (glycomaurin) and 6-methyl-4-(3′-methylbut-2′-enyl)carbazol-3-ol (glycomaurrol), whose structures were confirmed by synthesis and by cyclization to dihydroglycomaurin respectively. Glycomaurin has a ring system which has not been previously found in nature.

Abstract:
Two new carbazole alkaloids (1,2) and six known carbazole alkaloids (3–8) were isolated from Clausena anisum-olens. Their structures were elucidated based on extensive spectroscopic analysis. All isolated compounds (1–8) were evaluated for their anti-HIV effects on virus replication in MT-4 lymphocytes infected by HIV-1NL4-3 Nanoluc-sec virus, and new carbazole alkaloid 1 exhibited anti-HIV activity with an EC50 value of 2.4 μg/mL and SI of 7.1.

Abstract:
Structurally diverse carbazole alkaloids are valuable due to their pharmaceutical properties and have been isolated from nature. Experimental knowledge on carbazole biosynthesis is limited. The latest development of in silico analysis of the biosynthetic gene clusters for bacterial carbazoles has allowed studies on the biosynthesis of a carbazole skeleton, which was established by sequential enzyme-coupling reactions associated with an unprecedented carbazole synthase, a thiamine-dependent enzyme, and a ketosynthase-like enzyme. This review describes the carbazole biosynthetic mechanism, which

A new carbazole alkaloid (kurryam) oxygenated at the 4-position, hitherto unknown among carbazole alkaloids, has been isolated from the seeds of an Indian medicinal plant, Murraya koenigii (Rutaceae). The structure has been established as 4-hydroxy-(2′,2′,3)-trimethyl-(6,7)-dimethoxy pyranocarbazole from extensive 2D NMR spectral studies. In addition, two known carbazole alkaloids, (2′,2′,3)-trimethyl 6-methoxy pyranocarbazole and (2′,2′,3)-trimethyl 6-hydroxy pyranocarbazole were isolated from the seeds of the same plant, of which (2′,2′,3)-trimethyl 6-methoxy pyranocarbazole exhibited signif

Abstract:
The plants Murraya koenigii and Glycosmis pentaphylla are rich sources of different carbazole alkaloids. A number of monomeric carbazole alkaloids with C13, C18, and C23 carbon frames and a good number of dimeric carbazole alkaloids were isolated from these two plants. Scientists are still working on these two plants in search of more and more novel compounds. Many of these alkaloids have potential biological activities. Scientists have determined the structures of these compounds by detailed analysis of spectral data like UV, IR, Mass,1H NMR, and 13C NMR (1D and 2D). These procedures require
