Emerging evidence present credible support in favour of the potential role of mahanine and girinimbine.
Non-toxic herbal carbazole alkaloids occur in the edible part of Murraya koenigii, Micromelum minutum,
M. zeylanicum, and M. euchrestiolia. Mahanine and girinimbine are the major potent compounds from these species.
In fact, they interfered with tumour expansion and metastasis development through down-regulation of apoptotic and
antiapoptotic protein, also involved in the stimulation of cell cycle arrest. Consequently, these compounds were well
proven for the in-vitro and in vivo evaluation that could be developed as novel agents either alone or as an adjuvant
to conventional therapeutics. Therefore, mahanine and girinimbine analogs have the potential to be the promising
chemopreventive agents for the tumour recurrence and the treatment of human malignancies. In this review, an
updated wide-range of pleiotropic anticancer and biological effects induction by mahanine and girinimbine against
cancer cells were deeply summarized.
