| Abstract: | The present invention relates to two main components, mahanine and mahanimbine (dehydroxy-mahanine) from Murraya koenigii for the treatment of glioblastoma and cervical carcinoma. Mahanimbine exhibited anti-cancer activity against lymphoid leukemia, myeloid leukemia, glioma, cervical carcinoma, pancreatic, colon and lung cancers in nineteen cells of different genetic status. C-3 hydroxy and NH groups are responsible contributing groups for their cytotoxicity. Mahanine reduced the doses of cisplatin and paclitaxel in cervical cancer showing better efficacy and useful as an adjunct chemotherapeutic agent to reduce toxicity these two drugs. A new cheap process for this preparation was established. EtOAc extract containing alkaloids enriched with mahanimbine and mahanine, is active against glioma and cervical cancers. Mahanine is targeting the chaperone Hsp90 which led to the proteasome-dependent degradation of several Hsp90-client proteins in diverse carcinoma types, glioblastoma, cervical carcinoma and pancreatic adenocarcinoma irrespective of their tissue origins thereby killing the cancer cells. | ||
