Abstract
We discovered novel neuroprotective compounds by phenotypic screening using SOD1-mutant amyotrophic lateral sclerosis (ALS) patient induced pluripotent stem cell (iPSC)-derived motor neurons. Mechanistic analysis showed that the protective effect of initial hit compound 1 was likely due to the inhibition of MAP4Ks, including MAP4K4, a member of the MAP4K kinase family. Structural transformation led to compound 15f, which showed improved MAP4K4 inhibitory activity and superior neuroprotective effects compared to 1 in motor neurons. The results suggest that structural optimization based on MAP4K4 inhibitory activity might improve the neuroprotective effect of this series of compounds.
