Pharmacology in ENT.
This issue of The Journal of Laryngology & Otology is introduced by two review articles that highlight aspects of pharmacology and its utility in ENT. Bleeding, particularly epistaxis and post-tonsillectomy bleeding, forms a major part of the emergency work of any ENT department. Robb focuses on the possible role of tranexamic acid, with two recently published pilot studies looking at primary h...
متن کاملEnantioselective formal synthesis of ent-rhynchophylline and ent-isorhynchophylline.
Starting from (S)-tryptophanol, a formal synthesis of ent-rhynchophylline and ent-isorhynchophylline, involving stereoselective cyclocondensation, spirocyclization, and alkylation reactions, and the final adjustment of the oxidation level at the oxindole and piperidine moieties, is reported.
متن کاملent-Atisane and ent-kaurane diterpenoids from Isodon rosthornii.
A new ent-atisanoid (1) and three new ent-kauranoids (2-4) belonging to different types, along with four known compounds were isolated from Isodon rosthornii. Their structures were established by means of extensive spectroscopic analysis. The absolute configuration of 1 was further determined by X-ray diffraction. Compounds 1 and 5 are the first example of atisane-type diterpenoid from this plant.
متن کاملNew ent-abietane and ent-kaurane diterpenoids from Isodon rubescens.
Five new ent-abietane diterpenoids, ent-abierubesins A-E (1-5), and two new ent-kauranoids, hubeirubesins A and B (6, 7), together with three known diterpenoids (8-10), were isolated from the aerial parts of Isodon rubescens. Their structures were identified by means of extensive spectroscopic analysis, and the absolute stereochemistry of 1 was determined by single-crystal X-ray diffraction exp...
