ORM-10962 is a potent, highly selective inhibitor of sodium-calcium exchanger (NCX) (for the reverse and forward mode inhibition with IC50 values of 67 and 55 nM , respectively).
ARQ 736 is a potent and selective BRAF inhibitor. ARQ 736 is selectively potent in killing cancer cell lines harboring at least one mutated BRAF allele. BRAF mutations were detected in over 60% of melanomas and may account for a significant proportion of colon cancer patients whose tumors are resistant to anti-EGFR therapy. The B-Raf protein is a key signaling molecule in the mitogen activated protein kinase (MAPK) signaling pathway and has been implicated in the pathogenesis of a variety of cancers.
