Vasicine

Description

Vasicine, also known as peganine, belongs to the class of organic compounds known as quinazolines. Quinazolines are compounds containing a quinazoline moiety, which is made up of two fused six-member aromatic rings, a benzene ring and a pyrimidine ring. Vasicine is a very strong basic compound (based on its pKa). Vasicine has a cardiac–depressant effect, while vasicinone is a weak cardiac stimulant; the effect can be normalized by combining the alkaloids. Both the alkaloids in combination (1:1) Showed pronounced bronchodilatory activity in vivo and in vitro. It is additionally found in Peganum harmala. It has also been studied in combination with the related alkaloid vasicinone. Bromhexine, a synthetic compound imitating the molecular shape of vasicine, is a common ingredient of cough medicine for its mucolytic properties; it increases the production of serous mucus in the respiratory tract which makes the phlegm thinner and less viscous, which allows the cilia to more easily transport the phlegm out of the lungs. Vasicine is reported to have a uterine stimulant effect. Vasicine has been compared to theophylline both in vitro and in vivo. Both alkaloids are also respiratory stimulants. Vasicine is found in Justicia adhatoda, Galega officinalis, Linaria genistifolia, Nitraria komarovii, Peganum harmala, Peganum nigellastrum and Sida cordifolia. Vasicine (peganine) is a quinazoline alkaloid.
