micromelum pubescens/白血病

Mahanine, a carbazole alkaloid occurs in the edible part of Micromelum minutum, Murraya koenigii and related species has been found to induce apoptosis in human myeloid cancer cell (HL-60). Concentration of 10 microM mahanine caused a complete inhibition of cell proliferation and the induction of

On the basis of a leishmanicidal assay-guided isolation, two new monoterpene coumarins, minutin A and minutin B, were purified from Micromelum minutum leaves together with four known coumarins, 8,4″-dihydroxy-3″,4″-dihydrocapnolactone-2',3'-diol, 8-hydroxyisocapnolactone-2',3'-diol,

Extracts of Micromelum integerrimum (Buch.-Ham. ex Coleb.) M. Roem. were fractionated based on in vivo activity in mice in the P-388 lymphocytic leukemia system. Activity in ethanol extracts was concentrated in the chloroform partition fraction, which was further resolved by chromatography on silica

1 Mahanine, a naturally occurring carbazole alkaloid in some Asian vegetables, has been shown to exhibit antimutagenicity, antimicrobial activity, cytotoxicity, and other biological properties. 2 In the present study, we investigated the effect of mahanine on the activation of the apoptotic pathway

One hundred and fifty-five extracts from 93 terrestrial species of plants in Peninsula Malaysia were screened for in vitro photo-cytotoxic activity by means of a cell viability test using a human leukaemia cell-line HL60. These plants which can be classified into 43 plant families are diverse in
