生物活性

Ketanserin (Vulketan Gel) is specific 5-HT2A serotonin receptor antagonist with a Ki of 2.5 nM for rat and human 5-HT2A. Ketanserin (Vulketan Gel) is a drug with affinity for multiple G protein-coupled receptors. Ketanserin ( Vulketan Gel) inhibits rat and human 5-HT2C with Ki of 50 and100 nM, respectively and has higher affinity binding for alpha-1 adrenergic (Ki = ~ 40 nM) and Histamine H1 (Ki = 2 nM). Ketanserin (Vulketan Gel) can also be used to discriminate between 5-HT1D and 5-HT1B receptor subtypes. Ketanserin (Vulketan Gel) has antihypertensive properties. Ketanserin (Vulketan Gel) also reduces platelet aggregation produced by serotonin. Ketanserin also has high affinity for alpha-1 adrenergic receptors, and very high affinity for histamine H1 receptors. Ketanserin (Vulketan Gel) was shown to reduce the severity and frequency of the vasospasm in Raynaud’s phenomenon.

化学数据

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
