AE0047 Hydrochloride is a blocker of calcium, and used in the research of the hypertensive disease.

Imperatoxin A，源自非洲蝎Pandinus imperator毒液的一种肽毒素，作为Ca2+-释放通道/兰尼碱受体（RyRs）的激活剂，促进Ca2+从肌浆网流入细胞。

(S)-Lercanidipine hydrochloride is the S-enantiomer of Lercanidipine hydrochloride. (S)-lercanidipine hydrochloride is a potent blocker of calcium channel.

Vindorosine has blood vessel relaxation effect, possible underlying mechanisms involving the inhibition of Ca(2+) entry via L-type Ca(2+) channels in vascular smooth muscles.

(-)-Praeruptorin A has anti-inflammatory, anti-contractile and anti-hyperplasia activities, it exerts distinct relaxant effects on isolated rat aorta rings dependent on endothelium and nitric oxide synthesis;it also can significantly suppress airway inflammation and airway remodeling induced by ovalbumin challenge, and is a potential candidate for the treatment of asthma. (-)-Praeruptorin A resensitizes Pgp-mediated MDR (Pgp-MDR) cancer cells to cancer drugs.

L-Ascorbic acid-13C是一种13C标记的L-Ascorbic acid (T0928)。L-Ascorbic acid (L-Ascorbate)作为内源性抗氧化剂，是一种电子供体，并选择性抑制Cav3.2通道 (Cav3.2 channels），其IC50为6.5 μM。同时，L-Ascorbic acid促进胶原沉积且抑制弹性生成。通过产生活性氧 (ROS）及选择性损伤癌细胞，L-Ascorbic acid显现出抗癌作用。

PPZ2 is a novel DAG-activated TRPC3/TRPC6/TRPC7 channels activator.

Calceolarioside A shows potent activity against visceral leishmaniasis. It can induce a dose-related aggregant effect on rabbit platelets, which may be partly related to a calcium-dependent mechanism. Calceolarioside A also has potent antioxidative activi
