Safety evaluation of standardized Ayurvedic formulation-Panchvalkala, by subacute toxicity study.

Ethnopharmacological Relevance: Panchvalkala is a conventional Ayurvedic medicine used as a douche in gynecological disorders such as leucorrhea, infertility, and endometriosis. Recently, we have reported the anticancer activity of Panchvalkala aqueous extract (PVaq) in cervical cancer cell lines, SiHa (HPV16+), HeLa (HPV18+), and mouse papilloma models.

Aim Of The Study: Here, we have evaluated the safety of the aqueous extract of Ayurvedic formulation, Panchvalkala (PVaq), in Swiss albino mice by performing subacute toxicity study.

Panchvalkala, a traditional Ayurvedic formulation, exhibits antineoplastic and immunomodulatory activity in cervical cancer cells and C57BL/6 mouse papilloma model.

Ethnopharmacological Relevance: Panchvalkala, an Ayurvedic traditional formulation has references in Charak Samhita and Bhavaprakasha Nighantu for the treatment of women with endometriosis-related problems, leucorrhea and vaginal ailments. The formulation comprises of equal ratios of the barks from Ficus glomerata, Ficus virens, Ficus religiosa, Ficus benghalensis, and Thespesia populnea.

Aim Of The Study: The present study aimed to evaluate the anticancer and immunomodulatory activity of aqueous extract of Panchvalkala (PVaq) against cervical cancer in vitro and in vivo.

Novel Aza-resveratrol analogs: synthesis, characterization and anticancer activity against breast cancer cell lines.

Novel Aza-resveratrol analogs were synthesized, structurally characterized and evaluated for cytotoxic activity against MDA-MB-231 and T47D breast cancer cell lines, which exhibited superior inhibitory activity than parent resveratrol compound. The binding mechanism of these compounds with estrogen receptor-α was rationalized by molecular docking studies which indicated additional hydrogen binding interactions and tight binding in the protein cavity. Induction of Beclin-1 protein expression in breast cancer cell lines after treatment with newly synthesized resveratrol analogs indicated inhibition of growth of these cell lines through autophagy.
