Exploration of anticancer potential of Lantadenes from weed Lantana camara: Synthesis, in silico, in vitro and in vivo studies.

Naturally occurring pentacyclic triterpenoids and their semisynthetic analogues have engrossed increasing attention for their anticancer potential and exhibiting promising role in discovery of new anticancer agents. Present study include the semi synthetic modifications of Lantadenes from the weed Lantana carama and their structures delineation by FT-IR, 1H-NMR, 13C-NMR & mass spectroscopy. All the compounds were scrutinized for in vitro cytotoxicity, ligand receptor interaction and in vivo anticancer studies. Most of the novel analogues displayed potent antiproliferative activity against A375 & A431 cancer cell lines and found superior to parent Lantadenes. In particular, 3β-(4-Methoxybenzoyloxy)-22β-senecioyloxy-olean-12-en-28-oic acid was found to be most suitable compound, with IC 50 value of 3.027 μM aganist A375 cell line having least docking score (−69.40 kcal/mol). Promising anticancer potential of the lead was further indicated by significant reduction in tumor volume and burden in two stage carcinoma model. These findings suggests that the Lantadene derivatives may hold promising potential for the intervention of skin cancers. Anticancer potential of Lantadene esters against skin malignancy. [Display omitted] • Naturally existing Lantadenes were isolated from the weed Lantana camara and followed by semi-synthetic modifications at C-3 position. • Structural confirmation of newly synthesized molecules were delineated by IR, NMR and mass spectroscopic methods. • Pre-clinical Investigations were performed to evaluate anticancer activity of Lantadene derivatives. • An outcome of this study suggests promising anticancer potential of lead analogue. • Semi-synthetic modifications of naturally existing Lantadenes were made at C-3 position. • Structural confirmation was delineated by various spectroscopic methods followed by determination of anticancer potential. • An outcome suggests promising anticancer potential of lead analogue.
