Oblongine chloride may have potential haemodynamic effects, it can cause a dose-dependent reduction of systolic and diastolic blood pressure, and that these effects are not mediated by α²-adrenergic receptor stimulation.
Dehydrocrebanine has strong activity against promyelocytic leukemia cells (HL-60) with an IC50 of 2.14 ug/mL. It also shows potent antimalarial activity with an IC50 value of 70 ng/ml.
Dicentrine, a selective α±(1)-adrenoceptor antagonist with potent antiarrhythmic and antihypertensive activities, it also has antinociception in different models of chemical pain.
Isotetrandrine is a small molecule inhibitor, on various aspects of LPS-induced inflammation in vitro and in vivo. It dose-dependently suppresses the severity of LPS-induced ALI by inactivation of MAPK and NF-κB, which may involve the inhibition of tissue
l-Stephanine is a potent and highly selective alpha 1 adrenoceptor blocker, inhibits anococcygeus muscle contraction induced by phenylephrine with pA2 values of 6.76. Stephanine shows significant antiplasmodial activities with IC(50) ranged from 1.2 uM to 52.3 uM. Stephanine and crebanine have high inhibitory activity against gram-positive animal pathogenic bacteria, with MIC values of 0.078-0.312g l, but low inhibitory activity against gram-negative animal pathogenic bacteria, they also inhibit hyphal growth of the plant pathogens Cercospora kaki.
