title: Synthesis and bronchodilatory activity of four new derivatives of deoxyvasicine.
abstract: As part of a continuing effort aimed at the development of efficacious antihistaminic and bronchodilator agents for the treatment of asthma and related respiratory diseases, a series of novel trisubstituted deoxyvasicine derivatives was designed and synthesized. Bronchodilatory activity of pure samples of ligands 17a-d, and DL-8-chlorovasicine hydrochloride is investigated and compared with isoprenaline and aminophylline. These studies confirm the activity of ligands 17a-d and the potentiating effect of 17c on aminophylline.
