Antioxidant and anticancer potential of ethyl acetate extract of bark and flower of Tecoma stans (Linn) and In Silico studies on phytoligands against Bcl 2 and VEGFR2 factors.

Summary

A study evaluated the antioxidant and anticancer properties of Tecoma stans extracts. The ethyl acetate extract contained the most valuable phytochemicals, particularly flavonoids. Purified flavonoid fractions were confirmed to be enriched. The ethyl acetate extract exhibited high antioxidant activity and dose-dependent cytotoxicity against breast cancer cells. Analysis identified 10 medicinal flavonoids, with 3,5-O-dicaffeoylquinic acid and Isorhamnetin-3-O-rutinoside showing potential interactions with Bcl 2 and VEGFR2, respectively. These findings suggest that T. stans extracts have significant medicinal potential as antioxidant and anticancer agents, pending further animal studies.

Immunotoxical, neurotoxical, histopathological and immunohistopathological alterations of Nerium oleander and Tecoma stans methanolic extract on Biomphalaria alexandrina snails.

Summary

The study investigated the molluscicidal effects of extracts from Nerium oleander and Tecoma stans on B. alexandrina snails. Results showed that N. oleander had a stronger effect than T. stans, and the extracts had no negative effects on other organisms. Exposure to sub-lethal concentrations of the extracts caused a decrease in certain blood cell types and biochemical changes, as well as morphological alterations in snail organs. The extracts could be used as a safe and affordable alternative to synthetic molluscicides for controlling the spread of schistosomiasis.
