Vasicinone is a quinazoline alkaloid. It shows bronchodilator action in vitro[1] but bronchoconstrictor action in vivo.[2] Vasicinone was shown to have an antianaphylactic action.[3] It has been found within Peganum harmala.[4]

Vasicinone has also been studied in combination with the related alkaloid vasicine. Both the alkaloids in combination (1:1) showed pronounced bronchodilatory activity in vivo and in vitro.[5] Both alkaloids are also respiratory stimulants.[5] Vasicine has a cardiac–depressant effect, while vasicinone is a weak cardiac stimulant; the effect can be normalized by combining the alkaloids.[5][3] Vasicine is reported to have a uterine stimulant effect.[3]
