Bioactive abietenolide diterpenes from Suregada procera.

The phytochemical investigation of the leaves and the roots of Suregada procera afforded the new ent-abietane diterpenoid sureproceriolide A (1) along with the known secondary metabolites 8,14β:11,12α-diepoxy-13(15)-abietane-16,12-olid (2), jolkinolide A (3), jolkinolide E (4), ent-pimara-8(14),15-dien-19-oic acid (5), sitosterol (6), oleana-9(11):12-dien-3β-ol (7), and oleic acid (8). Their structures were elucidated by NMR spectroscopic and mass spectrometric analyses, and the structure of jolkinolide A (3) was confirmed by single-crystal X-ray diffraction analysis. Sureproceriolide A (1) showed modest activity against the Gram-positive bacterium Staphylococcus lugdunensis (MIC = 31.

Antiviral Rotenoids and Isoflavones Isolated from ssp. .

Three new (-) and six known rotenoids (-), along with three known isoflavones (-), were isolated from the leaves of ssp. . A new glycosylated isoflavone (), four known isoflavones (-), and one known chalcone () were isolated from the root wood extract of the same plant.

Identification of epidermal growth factor receptor-tyrosine kinase inhibitor targeting the VP1 pocket of human rhinovirus.

Screening a library of 1,200 preselected kinase inhibitors for anti-human rhinovirus 2 (HRV-2) activity in HeLa cells identified a class of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) as effective virus blockers. These were based on the 4-anilinoquinazoline-7-oxypiperidine scaffold, with the most potent representative AZ5385 inhibiting the virus with EC of 0.35 µM.

The impact of deontological and teleological variables on the intention to visit green hotel: The moderating role of trust.

Green hotels have grown in popularity due to customers' increased awareness of environmental issues. This study aims to construct and evaluate a model that combines the theory of Planned Behavior (TPB) and the theory of ethics to explain green hotel visitors' intentions and behavior. The study also considers the role of trust & subjective norms as a moderator.

Crotofolane Diterpenoids and Other Constituents Isolated from .

Six new crotofolane diterpenoids (-) and 13 known compounds (-) were isolated from the MeOH-CHCl (1:1, v/v) extracts of the leaves and stem bark of . The structures of the new compounds were elucidated by extensive analysis of spectroscopic and mass spectrometric data. The structure of crotokilwaepoxide A () was confirmed by single-crystal X-ray diffraction, allowing for the determination of its absolute configuration.
