TSHR antagonist S37b, the less potent enantiomer of TSHR antagonist S37a, exhibits minimal efficacy in inhibiting the thyrotropinreceptor (TSHR). It is utilized in thyroid function research[1].
Potent and selective melanocortin MC4 receptor antagonist (IC50 values are 0.5 and 44.9 nM at MC4 and MC3 respectively) that antagonizes the effects of α-MSH. Suppresses thyrotropin-releasing hormone (TRH) release, attenuates food intake and reduces forma
