生物活性

TASIN-1 (Truncated APC Selective INhibitor-1) targets EBP- (Emopamil-binding protein; D8-D7 sterol isomerase) dependent cholesterol biosynthesis and selectively induces cellular cholesterol depletion and apoptotic death in human colorectal cancer (CRC) cultures harboring APC truncations under lipid-deficient conditions (0.2% FCS or 2% lipoprotein-deficient serum; IC50 from 35 nM/HT29 to 4.9 μM/HT55 in 72 hrs) as a result of defective cholesterol homeostasis regulation, while exhibiting little cytotoxicity toward wild-type APC CRC cells or non-transformed human colonic and bronchial epithelial cells (IC50 >50 μM in 72 hrs). TASIN-1 intraperitoneal injection is efficacious against the growth of CRC tumors with trunctated APC using the genetically engineered CPC;Apc mice (20 mg/kg twice a week) and two xenograft murine models (DLD1 & HT29; 40 mg/kg twice daily) without apparent toxicity to the animals.

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）

小鼠

重量 (kg)体表面积 (m2)Km系数

0.020.0073

动物 B的Km系数动物 A的Km系数大鼠0.150.0256

兔1.80.1512

豚鼠0.40.058

仓鼠0.080.025

狗100.520

动物 A (mg/kg) = 动物 B (mg/kg) ×

例如，依据体表面积折算法，将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量，需要将22.4 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。
