SB-431542 is a drug candidate developed by GlaxoSmithKline (GSK) as an inhibitor of the activin receptor-like kinase (ALK) receptors, ALK5, ALK4 and ALK7.^[1] However, it is not an inhibitor of anaplastic lymphoma kinase (which are commonly known as ALK inhibitors).

In-vitro studies

While SB-431542 has not proved directly useful for any clinical application, it is used for several applications in molecular biology. It suppresses the TGF-beta-induced proliferation of osteosarcoma cells in humans.^[1] SB431542 can also be used in combination with LDN193189, CHIR99021 and DAPT to transform astrocytes into neurons.^[2] It is also commonly used for immunological studies, for instance as a TGF-β inhibitor to facilitate the generation of dendritic cells from peripheral blood monocytes. ^[3]
