Valorphin is a derivative of dihydrovaltrate with opioid analgesic activity, binds to rat mu-opioid receptor, with an IC50 of 14 nM. Valorphin has low affinity for δ-opioid receptor (IC50, 200 nM) and shows no affinity for κ receptor (IC50, >10 μM). Valorphin (>10 μM) decreases spontaneous firing rate of cerebellar rat Purkinje cells. Valorphin (1 μM) treatment 48 h prior to 0.1 μM epirubicin, or 0.1 μM vincristine, or 0.05 μM vincristine, causes 100% tumor cell death.

Valorphin exhibits pronounced analgesic activity in mice, rats and rhesus monkeys via s.c, with ED50s of ≤5.2 mg/kg, but barely active after oral administration. Valorphin (1 mg/kg) causes 42% of tumor growth inhibition in female BLRB mice bearing syngeneic mammary carcinoma cells.
