Description: ACH-000143 is a Potent and Peripherally Preferred Melatonin Receptor Agonist that Reduces Liver Triglycerides and Steatosis in Diet-Induced Obese Rats. ACH000143 demonstrated subnanomolar potency at MT1/MT2 receptors, high oral bioavailability in rodents, peripherally preferred exposure, and excellent selectivity in a broad panel of targets. Two-month oral administration of ACH000143 in high-fat diet rats led to a reduction in body weight gain similar to dapagliflozin with superior results on hepatic steatosis and triglyceride levels. An early toxicological assessment indicated that ACH000143 was devoid of hERG binding, genotoxicity, and behavioral alterations at doses up to 100 mg/kg p.o., supporting further investigation of this compound as a drug candidate.

Product Data:

Biological target: ACH-000143 is a melatonin receptor agonist, with EC50 values of 0.06 nM and 0.32 nM for MT1 and MT2, respectively.
In vitro activity: TBD
In vivo activity: The rats from the Chow Vehicle group also gained weight steadily, though less rapidly than the ones on HFD. Treatment with compound 10b (ACH000143) (10 and 30 mg/kg) significantly reduced BW gain on days 13 to 32 (p < 0.05) in comparison with the HFD Vehicle control and dapagliflozin (5 mg/kg) on days 2 to 48, 50 to 54, and 56 (p < 0.05). Compared with the HFD Vehicle, 10b significantly reduced the weekly BW gain on weeks 2 (10 and 30 mg/kg, p < 0.01), 3 (30 mg/kg only, p < 0.05), and 7 (10 and 30 mg/kg, p < 0.05), 15a at 30 mg/kg on week 2 (p < 0.05), and dapagliflozin on week 1 (p < 0.001) (Figure 3B). A trend toward significantly reduced BW gain from day 1 to day 57 versus HFD Vehicle was observed for 10b (10 and 30 mg/kg, p = 0.098) and dapagliflozin (p = 0.051).
