LMI070 is an SMN2 splice modulator.1 It selectively enhances SMN2 splicing by stabilizing the complex formed by the U1 small nuclear ribonucleic protein (snRNP) and SMN2 pre-mRNA. LMI070 (3-30 mg/kg) increases the expression of the full-length SMN2 trancript and, at doses ranging from 0.3 to 30 mg/kg, increases SMN protein levels in the brain and spinal cord in the C/+ mouse model of spinal muscular atrophy (SMA).1,2 It also increases survival of SMNΔ7 mice, a model of severe SMA, when administered at doses of 1 and 3 mg/kg.1

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
