TM-N1324 is an agonist of G-Protein-Coupled Receptor 39 (GPR39) with EC50s of 9 nM/5 nM in the presence of Zn2+, and 280 nM/180 nM in the absence of Zn2+ for human/murine GPR39.
TM-N1324 activates human GPR39 with high efficacy and potencies of 280 nM and 9 nM in the absence and presence of Zn2+, respectively. TM-N1324 has similar potencies on murine GPR39, 180 nM and 5 nM. TM-N1324 is also found to have promising in vitro ADME properties. TM-N1324 has reasonably good aqueous solubility (65 μM at pH 7.0). Measurements of somatostatin confirms that the GPR39 agonist TM-N1324 increases somatostatin release by 53%[1].
