Mark P. Wentland

Professor Emeritus, Chemistry and Chemical Biology

Mark Wentland began his career in drug discovery in 1970 when he joined the medicinal chemistry department at Sterling Winthrop Inc. During his 24 years at Sterling Winthrop, he held various scientific and administrative leadership positions and was also Adjunct Professor of Chemistry at Rensselaer. In 1994, he left Sterling-Winthrop and joined the chemistry faculty at Rensselaer as Professor of Chemistry. During the period 1997-2015, he held the concurrent position of Adjunct Professor in the Department of Neuroscience and Experimental Therapeutics at Albany Medical College. Following his retirement from Rensselaer at the end of 2015, he was appointed to the position of Professor Emeritus.

Samidorphan -  Discovery of a medication approved by the US FDA when combined with olanzapine:  At Rensselaer, Professor Wentland led an NIH-funded research program in medicinal chemistry aimed at identifying novel, long-acting oral medications to treat opioid and cocaine use disorders. This research yielded 22 issued US Patents and in four drugs entering clinical trials. One of these drugs, the highly potent mu opioid receptor antagonist samidorphan, has undergone extensive clinical testing sponsored by our licensing partner Alkermes, Inc. LYBALVI(TM) (aka, ALKS 3831), an oral medication combining samidorphan with olanzapine, was approved by the US FDA on June 1, 2021 to treat schizophrenia and bipolar I disorder. Olanzapine is an established antipsychotic agent that can cause significant weight gain. The role of samidorphan is to mitigate this olanzapine-associated weight gain.
