ERK Inhibitor

Hordenine (Ordenina; Peyocactine) is a multifunctional alkaloid with oral activity and blood-brain barrier penetration. Hordenine inhibits LPS-induced phosphorylation of p38, JNK, ERK1/2, p65, IκB, and AKT, prevents p65 nuclear translocation, and suppresses inflammatory cytokines and mediators. Hordenine promotes M2 macrophage polarization, restores blood-milk barrier integrity, alleviates oxidative stress by reducing ROS and MDA, and attenuates LPS-induced lung injury and pulmonary edema. Hordenine inhibits cAMP production, CREB phosphorylation, and MITF expression, thereby suppressing melanin synthesis in melanocytes and reconstructed epidermis. Hordenine activates the Wnt/β-catenin signaling pathway, promotes dermal papilla cell proliferation and hair shaft elongation, and accelerates hair regeneration. Hordenine activates DRD2, acts as a D3R partial agonist, α2A-AR full agonist, and 5-HT2A-R antagonist, and inhibits SERT and DAT. Hordenine inhibits α-synuclein accumulation and ameliorates motor deficits in Parkinson's disease models. Hordenine limits alcohol intake, reduces relapse drinking behavior, and modulates alcohol-induced conditioned place preference. Hordenine can be used for research on mastitis, skin pigmentation, acute lung injury, foodborne diseases, hair loss, Parkinson's disease, bacterial infections, and alcohol use disorder.
