To address the hERG liability of MCHR1 antagonists such as 1 and 2, new analogs such as 4 and 5 that incorporated a polar heteroaryl group were designed and synthesized. Biological evaluation confirmed that these new analogs retained MCH R1 activity with greatly attenuated hERG liabilities as indicated in the Rb efflux assay.
为了解决MCHR1拮抗剂(例如1和2)的hERG责任,设计并合成了新的类似物(例如4和5),它们掺入了极性杂芳基。
生物学评估证实,这些新的类似物保留了MCH R1的活性,并大大降低了hERG的耐受性,如Rb外排试验所示。
