Abstract:
Leishmaniases are a spectrum of poverty-linked neglected parasitic diseases that are endemic in 88 countries around the globe and affect millions of people every year. Currently available chemotherapeutic options are inadequate due to side effects, high cost, prolonged treatment, and parasite resistance. Thus, there is an existing need to develop new potent and safer leishmanicidal drugs. Considering the folkloric antiulcer and leishmanicidal use of the genus Berberis and its alkaloids, 5 reported alkaloids, namely berberine (1), palmatine (2), columbamine (3), 8-trichloromethyldihydroberberine (4), and jatrorrhizine (5), were isolated from the roots of Berberis glaucocarpa using classical (column and preparative chromatography) and modern isolation techniques (Sephadex LH-20). Their structures were elucidated and established from 1D and 2D spectroscopic data. The isolated alkaloids displayed excellent antileishmanial potential with IC 50 values ranging from 1.50 to 2.56 µM: 1 (1.50 ± 0.53 µM), 2 (2.31 ± 0.37 µM), 3 (2.56 ± 0.48 µM), 4 (1.40 ± 0.90 µM), 5 (2.44 ± 1.34 µM). While the IC 50 value for the standard drug (Amphotericin-B) was found to be 1.08 ± 0.95 µM. All of the isolated alkaloids displayed excellent antileishmanial potential as well as minimal cytotoxicity against THP-1 monocytic cells. Molecular docking analysis has revealed Leishmania N-myristoyl transferase, methionyl-tRNA synthetase, pteridine reductase 1, oligopeptidase B, tyrosyl-tRNA synthetase, and/or glycerol-3-phosphate dehydrogenase to be potential protein targets for the alkaloids.
