Methoxamine is an alpha-adrenergic agonist that induces prolonged peripheral vasoconstriction, and can also stimulate the release of arginine vasopressin in humans. In clinical trials, methoxamine was found to improve fecal incontinence. It had been marketed by Glaxo-Smith-Kline under the brand name Vasoxyl but has been discontinued. Methoxamine was also found to stimulate the induction of hiPSC-derived hepatoblasts to ALBUMIN+ cells.

Hepatic differentiation of hiPSC colonies grown on SNL feeder cells occurred in three culture stages over 18 - 21 days concluding with hepatocyte culture medium containing 20 ng/ml recombinant human hepatocyte growth factor and 20 ng/ml recombinant human Oncostatin M for 7 - 8 days. Methoxamine from a commercial compound screen was included in the stage 3 hepatocyte culture media. After 7 days incubation cells were subjected to anti-ALBUMIN immunostaining, and the number and induction rate of ALBUMIN+ cells was examined. Methoxamine was the sole effective compound among the 1,120 tested. The induction rate of hiPSC-derived hepatoblasts into ALBUMIN+ cells in the populations treated with methoxamine was 33.7%. Methoxamine was then titrated against hiPSC-derived hepatoblasts cultures across a range of 0.001 μM to 100 μM and demonstrated a dose-dependent induction activity with the highest efficiency at 1 μM.
