BTB-1 (86030-08-2) is a? selective, ATP-competitive and reversible inhibitor of mitotic kinesin Kif18A, IC50=1.7 mM.1,2 Binds to an allosteric site near Kif18A loop 5 preventing a range of conformational changes thereby blocking motor function.3 Inhibits the differentiation of mouse bone marrow cells to dendritic cells.4 Suppresses the replication of influenza A virus, inhibiting activation of AKT, p38 MAPK, SAPK and RanBP3 leading to the prevention of nuclear export of viral ribonucleoprotein complexes. Greatly improves the viability of IAV-infected mice.5

BTB 1 is a small molecular inhibitor of the mitotic motor protein Kif18A.
