SEN177 is a potent glutaminyl cyclase (QPCT) inhibitor with an IC 50 of 0.013μM for glutaminyl-peptide cyclotransferase-like (QPCTL). SEN177 has a K i of 20 nM for human glutaminyl cyclase (hQC). SEN177 greatly reduces the early stages of mutant HTT oligomerisation and reduces the percentage of neurons with Q80 aggregates. SEN177 has the potential for Huntington’s disease research.
