IC50 & Target


In Vivo

At P16, vehicle treated D7 mice are much smaller than heterozygous littermate controls and appear moribund. In contrast, D7 mice treated with the high dose of SMN-C3 show a phenotype similar to that of heterozygous controls. SMN-C3 treatment induces a dose-dependent bodyweight gain in the D7 mice, with some animals showing a body weight that is ~80% that of heterozygous controls. SMN-C3 normalizes the motor behavior of D7 mice, illustrated by the ability of the mice to right themselves as quickly as heterozygous controls and by their level of locomotor activity. Most importantly, whereas vehicle-treated mice die within 3 weeks after birth with a median survival of 18 days, SMN-C3 treatment increases survival in a dose-dependent manner to a median survival time of 28 days in the low-dose (0.3 mg/kg per day) group. In the two higher-dose groups (1 and 3 mg/kg per day), ~90% of animals survive beyond P65 when the study is completed[1].

Animal Administration

The animals are treated with SMN-C3 at doses of 0.3, 1, and 3 mg/kg per day by intraperitoneal injections from P3 through P23 and thereafter at doses of 1, 3, and 10 mg/kg per day, respectively, by oral gavage[1].
