rhododendron dauricum/phosphatase

In spite of the critical role of the natural products in drug discovery, surprising little attention has been placed on endangered and rare plant species that could play a pivotal role in pharmaceutical and fiber development. Protein tyrosine phosphatase-1B (PTP1B), which blocks insulin signaling,

OBJECTIVE To evaluate the hepatoprotective potential of ethyl acetate fraction of Rhododendron arboreum (Family: Ericaceae) in Wistar rats against carbon tetrachloride (CCl(4))-induced liver damage in preventive and curative models. METHODS Fraction at a dose of 100, 200, and 400 mg/kg was

Five pairs of optically pure meroterpenoid enantiomers (1a/1b-5a/5b) and two known compounds (6 and 7) were isolated from Rhododendron fastigiatum. Compounds 1a/1b-5a/5b were resolved from naturally scalemic mixtures by chiral HPLC. Their structures were elucidated by spectroscopic methods, X-ray

Mollebenzylanol A is a tyrosine phosphatase 1B inhibitor isolated from the leaves of Rhododendron molle in 2018 that has a highly functionalized structure. The first enantioselective total synthesis of mollebenzylanol A was achieved in 13 steps from a known chiral starting material. An
