It serves as a substrate for the P-glycoprotein efflux pump and exhibits high membrane permeability and good metabolic stability. Antitrypanosomal agent 24 binds to DNA/RNA via intercalation.

VEGFR-2/P-gp-IN-1 is a derivative of Licochalcone A, functioning as an orally active inhibitor of VEGFR-2 (IC50= 0.885 μM) and P-glycoprotein (P-gp). It combats tumor proliferation and overcomes chemotherapy resistance by simultaneously inhibiting VEGFR-2 kinase activity and the P-gp drug efflux pump. This compound suppresses the phosphorylation of VEGFR-2 and proteins in the downstream PI3K/AKT signaling pathway, induces apoptosis, arrests cells in the S phase, and inhibits invasive migration.
