... biological activity of harmine in vivo. Interestingly, our results show that harmine not only inhibits the protein–ser- ine ⁄ threonine kinase activity of the mature enzyme, but also the tyrosine autophosphorylation ... phosphorylation of Thr125 is also blocked by harmine, confirm- ing the use of this b-carboline alkaloid as a potent inhibitor of DYRK1A in cells. We show that har...
