Ezutromid (SMT C1100) is a first-in-class, orally active benzoxazole utrophin modulator with an EC₅₀ of 0.91 μM. Ezutromid can be used for the research Duchenne muscular dystrophy (DMD). Ezutromid inhibits CYP1A2 enzymic activity in human liver microsomes (HLM) with an IC₅₀ of 5.4 μM^[1][2].

Ezutromid induces increased levels of utrophin RNA in human muscle cells. Treatment of human DMD cells with Ezutromid lead to a 2-fold increase in utrophin protein levels at an optimal concentration of 0.3 uM after 3 days of treatment. Ezutromid was safe and well tolerated with plasma concentrations achieved suf cient to cause a 50% increase in concentrations of utrophin in cells. Ezutromid led to a 30% increase in Utrn mRNA level and resulted in a 2.0-fold increase in UTRN protein level^[3][4][5].
