Anti-colon cancer activity of Murraya koenigii leaves is due to constituent murrayazoline and O-methylmurrayamine A induced mTOR/AKT downregulation and mitochondrial apoptosis.[Pubmed:28675857]
Biomed Pharmacother. 2017 Sep;93:510-521.
In recent years, many alkaloids of plant origin have attracted great attention due to their diverse range of biological properties including anti-hyperglycemic, anti-oxidant, anti-inflammatory, anti-diabetic and anti-tumor activity. Herein, the pyranocarbazole alkaloids were isolated from leaves of Murraya koenigii and their anti-cancer potential was investigated in different cancer cell lines. Among all tested compounds, murrayazoline and O-Methylmurrayamine A demonstrated potent anti-cancer activity against DLD-1 colon cancer cells with the IC50 values of 5.7muM and 17.9muM, respectively, without any non-specific cytotoxicity against non-cancer HEK-293 and HaCaT cells. Further, studies of pure compounds revealed that the anti-cancer activity of compounds corresponds with altered cellular morphology, cell cycle arrest in G2/M phase, reactive oxygen species level and mitochondrial membrane depolarization of colon cancer cells. In addition, these compounds activated caspase-3 protein and upregulated Bax/Bcl-2 protein expression ratio leading to induction of caspase-dependent apoptosis in DLD-1 cells. These event induced by carbazole alkaloids also coincides with downregulation of Akt/mTOR suggesting downstream targeting of cell survival pathway. Thus, our in vitro studies not only provided scientific basis of the use of M. koenigii leaves in the traditional Indian Ayurveda medicines, but also expands possibilities of medicinal uses of M. koenigii leaves against colon cancer. Particularly, these findings will help in further investigating murrayazoline and O-Methylmurrayamine A or their improvised derivatives as new therapeutics for the treatment of colon cancer.
Total synthesis and neuroprotective effect of O-methylmurrayamine A and 7-methoxymurrayacine.[Pubmed:28508668]
J Asian Nat Prod Res. 2017 Jun;19(6):623-629.
O-Methylmurrayamine A (7) and 7-methoxymurrayacine (8) are natural products isolated from Murraya koenigii and Murraya siamensis, respectively. In this paper, we report the synthesis of 7 and 8 which are featured in the key step of cyclization to form carbazole intermediate 5 with mild conditions. The structures were confirmed by (1)H NMR, (13)C NMR, and HR-ESI-MS. In addition, compounds 7 and 8 were tested for their neuroprotective effects against H2O2-induced PC12 cell damage. The results showed that compounds 7 and 8 have neuroprotective effect.
Four new carbazole alkaloids from Murraya koenigii that display anti-inflammatory and anti-microbial activities.[Pubmed:26947457]
Org Biomol Chem. 2016 Mar 28;14(12):3322-32.
In our present study, four new, designated as murrayakonine A-D (), along with 18 known carbazole alkaloids were isolated from CHCl3 : MeOH (1 : 1) crude extracts of the stems and leaves of Murraya koenigii (Linn.) Spreng. The structures of the all isolated compounds were characterized by analysis of HR-ESI-MS and NMR (1D and 2D spectroscopy) results, and comparison of their data with the literature data. For the first time, all the isolates were evaluated for their anti-inflammatory activities, using both in vitro and in vivo experiments, against the key inflammatory mediators TNF-alpha and IL-6. The new compound murrayakonine A (), O-Methylmurrayamine A () and murrayanine () were proven to be the most active, efficiently inhibiting TNF-alpha and IL-6 release in a dose-dependent manner and showing decreased LPS induced TNF-alpha and IL-6 production in human PBMCs [corrected]. Furthermore, all the isolates were screened for their antimicrobial potential, and the compounds girinimbine () (IC50 3.4 muM) and 1-hydroxy-7-methoxy-8-(3-methylbut-2-en-1-yl)-9H-carbazole-3-carbaldehyde () (IC50 10.9 muM) displayed potent inhibitory effects against Bacillus cereus. Furthermore, compounds murrayamine J () (IC50 11.7 muM) and koenimbine () (IC50 17.0 muM) were active against Staphylococcus aureus. However, none of the compounds were found to be active against Escherichia coli or Candida albicans.
Total syntheses of murrayamine E, I, and K.[Pubmed:25915067]
J Org Chem. 2015 Jun 5;80(11):5666-73.
We describe efficient synthetic routes to murrayamine A (mukoenine C), O-Methylmurrayamine A, mahanine, O-methylmahanine, and murrayamine D and the first total syntheses of murrayamine E, I, and K. Key steps are a palladium-catalyzed construction of the carbazole framework and an annulation of the pyran ring, which is either catalyzed by phenylboronic acid or promoted by a Lewis acid.
Palladium(II)-catalysed total synthesis of naturally occurring pyrano[3,2-a]carbazole and pyrano[2,3-b]carbazole alkaloids.[Pubmed:24788002]
Org Biomol Chem. 2014 Jun 21;12(23):3866-76.
Seven naturally occurring pyranocarbazole alkaloids (pyrayafoline A-E, O-Methylmurrayamine A and O-methylmahanine) have been obtained by total synthesis using a palladium(II)-catalysed oxidative cyclisation of a diarylamine to an orthogonally diprotected 2,7-dihydroxycarbazole as key step.
Efficient iron-mediated approach to pyrano[3,2-a]carbazole alkaloids--first total syntheses of O-methylmurrayamine A and 7-methoxymurrayacine, first asymmetric synthesis and assignment of the absolute configuration of (-)-trans-dihydroxygirinimbine.[Pubmed:21279228]
Org Biomol Chem. 2011 Apr 7;9(7):2057-61.
Iron-mediated oxidative cyclisation provides an efficient approach to pyrano[3,2-a]carbazole alkaloids. Thus, improved routes to girinimbine and murrayacine as well as the first total syntheses of O-Methylmurrayamine A and 7-methoxymurrayacine are reported. Asymmetric epoxidation of girinimbine led to (-)-trans-dihydroxygirinimbine and the assignment of its absolute configuration.
Comparison of antioxidative properties of carbazole alkaloids from Murraya koenigii leaves.[Pubmed:14558763]
J Agric Food Chem. 2003 Oct 22;51(22):6461-7.
A new dimeric carbazole alkaloid, 8,10'-[3,3',11,11'-tetrahydro-9,9'-dihydroxy-3,3',5,8'-tetramethyl-3,3'-bis(4-met hyl-3-pentenyl)]bipyrano[3,2-a]carbazole (12), was isolated from the CH(2)Cl(2) extract of Murraya koenigii together with six known carbazole alkaloids, koenimbine (6), O-Methylmurrayamine A (7), O-methylmahanine (8), isomahanine (9), bismahanine (10), and bispyrayafoline (11). Their structures were determined on the basis of (1)H and (13)C NMR spectroscopic and mass spectrometric (MS) data. The antioxidative properties of 12 carbazole alkaloids isolated from leaves of M. koenigii were evaluated on the basis of the oil stability index together with their radical scavenging ability against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. On the basis of the lag time to reach a steady state, the 12 carbazoles were classified into three groups. It is suggested that an aryl hydroxyl substituent on the carbazole rings plays a role in stabilizing the thermal oxidation and rate of reaction against DPPH radical.
