Isotachysterol 3 是一种活性维生素 D 结构类似物的开环甾体化合物，也是制备维生素 D₃ 过程中的一种杂质。Isotachysterol 3 在无肾大鼠模型中能够显著刺激肠道钙的转运和骨钙动员。Isotachysterol 3 可用于不依赖于肾脏 1α-羟化的维生素 D 代谢研究。

Agelenin 是一种由 35 个氨基酸组成的多肽。Agelenin 可从阿格莱尼科蜘蛛 Agelena opulenta 中分离得到。Agelenin 与昆虫特异性钙通道抑制剂结构相似。

Gabapentin-D4是Gabapentin (T0702)的氘代化合物。Gabapentin的CAS号为60142-96-3。Gabapentin是GABA类似物，是一种抗癫痫药，可用于缓解神经性疼痛。

Marmin have anti-ulcer effects, which are ascribed primarily to the maintenance of the mucosal barrier integrity and inhibition of gastric motor activity and secondarily due to the prevention of the effects of endogenous acetylcholine and histamine.

Acetylcholine-D16 bromide是Acetylcholine bromide (T20344)中氘置换的一种形式。

Sulcardine 2HCl 是一种多离子通道阻滞剂，具有抗心律失常作用，可阻断 hERG 和hNav1.5通道的特性，可用于研究心房颤动和室性心律失常。

Lyso-globotriaosylceramide is a form of globotriaosylceramide that is lacking the fatty acyl group. It binds to Shiga toxin 1 (Stx1) in the presence of cholesterol and phosphatidylcholine but does not bind Stx2. It also reduces viability and aggregation of human neutrophils induced by phorbol 12-myristate 13-acetate when used at concentrations of 50 and 1 μM, respectively. Lyso-globotriaosylceramide accumulates in the brain, heart, kidney, liver, lung, and spleen in a mouse model of Fabry disease, a lysosomal storage disorder characterized by a deficiency in the enzyme α-galactosidase A. It also accumulates in the urine, kidney, and plasma of patients with Fabry disease. Lyso-globotriaosylceramide levels decrease in response to administration of the α-galactosidase inhibitor 1-deoxygalactonojirimycin in a transgenic mouse model of Fabry disease. Decreases in plasma and urine concentrations of lyso-globotriaosylceramide have been used as a biomarker for efficacy of enzyme replacement th

Verticilide是一种兰诺定受体(ryanodine)结合抑制剂，抑制ryanodine与兰诺定受体结合的IC50值为4.2 μM，对小鼠ryanodine受体的抑制作用较弱(IC50=53.9 μM)。

(S)-Nicardipine is the less active S enantiomer of Nicardipine. Nicardipine is a blocker of calcium channel(IC50 of 1 μM for blocking cardiac calcium channels).
