ML-109 is a potent and full thyroid stimulating hormone receptor (TSHR) agonist, with an EC50 of 40 nM.

ML-224 (ANTAG3) is a selective TSH receptor antagonist inhibits stimulation of thyroid function in female mice.

TSHR antagonist S37a is a highly selective thyrotropin receptor (TSHR) antagonist, with potential for the treatment of Graves' orbitopathy.

TSHR antagonist S37 is a selective and competitive thyrotropin receptor (TSHR) antagonist. TSHR antagonist S37 is the racemate of TSHR antagonist S37a.

NCGC00229600 is an allosteric inverse agonist of thyrotropin receptor (TSHR). NCGC00229600 inhibits both TSH and stimulating antibody activation of TSHRs endogenously expressed in Graves' disease.

TSHR antagonist S37b is an enantiomer of TSHR antagonist S37a, shows only a minor effect for TSHR inhibition. TSHR antagonist S37b can be used for the research of thyroid function.
