Vasicine (peganine) is a quinazoline alkaloid. It is found in Justicia adhatoda, after which it is named. It is additionally found in Peganum harmala.[1]
Vasicine has been compared to theophylline both in vitro and in vivo.[2] It has also been studied in combination with the related alkaloid vasicinone. Both the alkaloids in combination (1:1) showed pronounced bronchodilatory activity in vivo and in vitro.[3] Both alkaloids are also respiratory stimulants.[3] Vasicine has a cardiac–depressant effect, while vasicinone is a weak cardiac stimulant; the effect can be normalized by combining the alkaloids.[3][4] Vasicine is reported to have a uterine stimulant effect.[4]
