生物活性
VR23 is a novel proteasome inhibitor targeting β2 of the 20S proteasome subunit. VR23 produces a synergistic effect in killing multiple myeloma cells, including those that were resistant to bortezomib. VR23 as a structurally novel proteasome inhibitor with desirable properties as an anticancer agent.In ATH490 athymic mice engrafted with MDA-MB-231 metastatic breast cancer cells, VR23 (30mg/kg, i.p.) shows effective antitumor and antiangiogenic activities. VR23 also reduces adverse effects caused by paclitaxel in mice.

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。
