Research Funding
In 2022, Dr. Thomas received a National Institutes of Health (NIH) Academic Research Enhancement Award (AREA; R15 HL165700) through the National Heart, Lung and Blood Institute (NHLBI). His group seeks to develop inhibitors of the key enzyme involved in making melatonin, serotonin N-acetyl-transferase (SNAT, AANAT). By better understanding SNAT’s function, researchers could potentially develop a drug to treat seasonal affective disorder (SAD) and other disorders in which melatonin levels are abnormally high. The team includes UNK professors Allen Thomas (PI), Michael Moxley, Evan Hill and Surabhi Chandra in addition to external collaborators Profs. Philip Cole (Harvard), Ryan Wong (UNO) and Mark Wilson (UNL). We apply computational and experimental approaches including medicinal chemistry and zebrafish models of sleep to discover and optimize inhibitors to overcome weaknesses of earlier attempts at blocking melatonin synthesis.
