Vasicinone is a quinazoline alkaloid. It shows bronchodilatory activity in vitro[1] but bronchoconstrictory activity in vivo.[2] Vasicinone was shown to have an antianaphylactic action.[3]
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.[4] Both alkaloids are also respiratory stimulants.[4] Vasicine has a cardiac–depressant effect, while vasicinone is a weak cardiac stimulant; the effect can be normalized by combining the alkaloids.[4][3] Vasicine is reported to have a uterine stimulant effect.[3]
