Dysoxylum binectariferum Hook.f (Meliaceae), a rich source of rohitukine.
Rohitukine, a chromane alkaloid, is a precursor of flavopiridol, a promising anti-cancer compound. Currently in Phase III clinical trials, flavopiridol is a potent inhibitor of several cyclin-dependent kinases (CDKs). Rohitukine was first reported from Amoora rohituka (0.083% dry weight) followed by that in Dysoxylum binectariferum (0.9% dry weight), both belonging to the family Meliaceae. Here...
متن کامل5-Hydroxy-7-methoxy-2-methyl-4H-chromen-4-one from Dysoxylum macrocarpum (Meliaceae)
Both independent mol-ecules in the asymmetric unit of the title compound, C(11)H(10)O(4), are almost planar (r.m.s. deviations = 0.011 and 0.033 Å). In both mol-ecules, the hy-droxy group is intra-molecularly hydrogen bonded to the ketonic O atom. The independent mol-ecules are stacked alternately along the a axis, with the centroids of their chromene ring separated by distances of 4.490 (1) an...
متن کاملForest Trees in Human Modified Landscapes: Ecological and Genetic Drivers of Recruitment Failure in Dysoxylum malabaricum (Meliaceae)
Tropical agro-forest landscapes are global priority areas for biodiversity conservation. Little is known about the ability of these landscapes to sustain large late successional forest trees upon which much forest biodiversity depends. These landscapes are subject to fragmentation and additional habitat degradation which may limit tree recruitment and thus compromise numerous ecosystem services...
متن کاملAmbient ionization mass spectrometry imaging of rohitukine, a chromone anti-cancer alkaloid, during seed development in Dysoxylum binectariferum Hook.f (Meliaceae).
Rohitukine, a chromone alkaloid, possesses anti-inflammatory, anti-cancer and immuno-modulatory properties. It has been reported from four species, belonging to the families, Meliaceae and Rubiaceae. Stem bark of Dysoxylum binectariferum (Meliaceae) accumulates the highest amount of rohitukine (3-7% by dry weight). In this study, we examine the spatial and temporal distribution of rohitukine an...
