MedKoo CAT#: 510349

CAS#: 1229582-33-5

Description: URMC-099 is an orally bioavailable, brain penetrant mixed lineage kinase (MLK) inhibitor with IC50 of 19 nM, 42 nM, 14 nM, and 150 nM, for MLK1, MLK2, MLK3, and DLK, respectively. MLK3 activation is associated with many of the pathologic hallmarks of HAND and therefore represents a prime target for adjunctive therapy based on small-molecule kinase inhibition. In vitro, URMC-099 treatment reduced inflammatory cytokine production by HIV-1 Tat-exposed microglia and prevented destruction and phagocytosis of cultured neuronal axons by these cells.
