生物活性
Synta66 (S66) is a CRAC (Ca2+ release-activated Ca2+) channel inhibitor that blocks SOCE (store-operated Ca2+ entry) upon Ca2+ depletion from intracellular stores by thapsigargin in human vascular smooth muscle cells (VSMCs) with high potency (IC50 = 26 nM & 43 nM based on maximum Ca2+ level & rate of increase, respectly). Synta66 exhibits no affinity toward a range of receptors and ion channels (e.g. L-type Ca2+ channel) and does not affect TRPC1/5-mediated SOCE or store-operated non-selective cationic current. Leukocytes are reported to be less sensitive to CRAC inhibition by Synta66 (IC50 = 1.76 μM/HL-60, 1 ?M/Jurkat, 1.4 μM/rat RBL).

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Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
