Potent prokineticin (PK) receptor antagonist (IC50 values are 5.0 and 8.2 nM for PKR1 and PKR2, respectively). Reduces IL-1β and lL-6 expression in the joints and suppresses severity of arthritis in a mouse model of rheumatoid arthritis. Inhibits PK2-induced expression of pro-migratory chemokines and chemokine receptors in macrophages. Exhibits antitumor activity against glioblastoma and pancreatic cancer xenograft tumor models. Also exhibits antiangiogenic activity in vivo. Brain penetrant. Cell-permeable.
