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]
