Biological Activity

HTT splicing modulator 27 is a potent, orally bioavailable, and brain-penetrant small-molecule HTT pre-mRNA splicing modulator with mHTT protein EC50 of 66 nM.
HTT splicing modulator 27 (10 mg/kg) significantly reduces HTT e49–50 RNA in mouse brain in an acute model of Huntington's disease (HD).
HTT splicing modulator 27 (10 mg/kg) significantly reduces mHTT in brain in subchronic rodent models of HD.
HTT splicing modulator 27 shows minimal efflux ratios in both the MDR1 and the BCRP transporter assays and demonstrates a higher CNS effect (relative to peripheral tissues) when compared to branaplam (Cat# PC-45659).
