General description

A cell-permeable dihydropyrazinyl-thioacetamide that acts as an ATP-competitive MARK inhibitor (IC50 = 3.6 µM; [ATP] = 100 µM) with much reduced or little activity against GSK-3β, SAD-kinase B/BRSK-1, MARKK/TAO-1, Cdc2/cycB, and p38/SAPK (30%, 20%, 11%, 4%, and 0% inhibition, respectively; [inhibitor] = 50 µM). Shown to effectively block primary rat cortical neuron axon growth (5.7 µm/hr vs 32.5 µm/hr with or without 20 µM inhibitor) and prevent MARK2 overexpression-induced Tau Ser262 phosphorylation and cytotoxicity due to microtubule network breakdown in CHO cells (10 µM).

Par1b/MARK2 is a Ser/Thr kinase with pleiotropic effects that participates in the generation of apico-basal polarity in Caenorhabditis elegans. It is phosphorylated by atypical PKC(ι/λ) in Thr595 and inhibited. Because previous work showed a decrease in atypical protein kinase C
