Koenimbine is a natural product isolated from Murraya koenigii. The IC50 values of koenimbine in HT-29 and SW48 was calculated to be 50 μg/ml based on the MTT assay. The IC50 value was 75 μg/ml in IEC-18 cells.

Koenimbine is a natural product isolated from Murraya koenigii.
The IC50 values of koenimbine in HT-29 and SW48 was calculated to be 50 μg/ml based on the MTT assay. The IC50 value was 75 μg/ml in IEC-18 cells.
Koenimbine treatment resulted in significant down-regulation of CYCLD1 expression in SW48 cell line, but up-regulation of this gene in HT29 cell line. Expression of TBLR1, DKK1, GSK3B and β-catenin was significantly decreased after koenimbine treatment in HT-19 cell line. Moreover, expression of DKK1 and GSK3B was significantly decreased after koenimbine treatment in SW-40 cell line.
Koenimbine considerably increased DNA damage in HepG2 cells at subcytotoxic concentrations. Koenimbine induced the increased levels of reactive oxygen species (ROS) and reduction of GSH level in HepG2 cells, together with time-dependent loss of MMP. In addition, Koenimbine encouraged cells to express Hsp 70 and Hsp 90 in a concentration-dependent manner up to a concentration of 100 µM and a time-dependent manner at 24-hour incubation both at transcriptional and translational levels.

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。
