premna obtusifolia/breast neoplasms

Phytochemical investigation of Premna odorata Blanco, Lamiaceae, leaves afforded three new acylated iridoid glycosides 1-3 and two new acylated rhamnopyranoses 9 and 10, in addition to ten known compounds. The structures of the new compounds were confirmed using extensive 1D and 2D NMR analysis.

The study investigates the antioxidant, hepatoprotective and antiproliferative effects of novel icetexane diterpenoids (ice 1-4) isolated from hexane extract of stem bark of Premna tomentosa. A549, HT-29, MCF-7, MDA-MB-231, A431 cells were used to assess the antiproliferative activity by MTT assay.

Herbal and natural products have been used in folk medicine for centuries throughout the world. There has been renewed interest in screening higher plants for novel biologically active compounds, particularly those that effectively intervene in human ailments in the field of chronic diseases. The
