pimasertib hcl

Pimasertib HCl is an orally bioavailable small-molecule inhibitor of MEK1 and MEK2 (MEK1 2) with potential antineoplastic activity. Pimasertib selectively binds to and inhibits the activity of MEK1 2, preventing the activation of MEK1 2-dependent effector proteins and transcription factors, which may result in the inhibition of growth factor-mediated cell signaling and tumor cell proliferation. MEK1 2 (MAP2K1 K2) are dual-specificity threonine tyrosine kinases that play key roles in the activation of the RAS RAF MEK ERK pathway and are often upregulated in a variety of tumor cell types.

Thiorphan disulfide is an impurity of Racecadotril -- an antidiarrheal and enkephalinase inhibitor that reduces the amount of water and electrolytes absorbed into the intestine.
