ARI-1

ARI-1 is a receptor tyrosine kinase-like orphan receptor 1 (ROR1) inhibitor that binds to ROR1's extracellular Frizzled domain, effectively inhibiting aberrant ROR1 expression linked to non-small cell lung cancer (NSCLC) and EGFR-TKI-induced drug resistance. It modulates PI3K/AKT/mTOR signaling pathways in a ROR1-dependent manner and demonstrates potent inhibition of NSCLC cell proliferation and migration, exhibiting antitumor activity in vivo [1].
