DYRK

ID-8 is a DYRK inhibitor. ID 8 also stimulates proliferation at a steady rate (observed in serum-free media supplemented with 10 μM over a 30 day period).

AZ191 is a potent and selective DYRK1B inhibitor with IC50 of 17 nM, about 5- and 110-fold selectivity over DYRK1A and DYRK2.

Harmine, also known as telepathine, is a fluorescent harmala alkaloid belonging to the beta-carboline family of compounds. It occurs in a number of different plants, most notably the Middle Eastern plant harmal or Syrian rue (Peganum harmala) and the South American vine Banisteriopsis caapi (also known as "yage" or "ayahuasca"). Harmine reversibly inhibits monoamine oxidase A (MAO-A), an enzyme which breaks down monoamines, making it a RIMA. Harmine selectively binds to MAO-A but does not inhibit the variant MAO-B.

Paprotrain is a cell-permeable inhibitor of the kinesin MKLP-2, inhibits the ATPase activity of MKLP-2 with an IC50 of 1.35 μM and a Ki of 3.36 μM and shows a moderate inhibition activity on DYRK1A with an IC50 of 5.5 μM.
