Description

IC50: 631 ±98 and 690 ± 41 nM for human and rat CB1 receptors, respectively

LH 21 is a CB1 antagonist.

The endogenous cannabinoid system plays a critical modulatory role in feeding behavior and metabolism, acting at both peripheral and central levels. Recently studies suggest that the chronic administration of cannabinoid CB1 receptor antagonists is effective in experimental obesity.

In vitro: Previous study showed that LH-21 was able to inhibit the binding of [3H]CP55940 to cloned human and rat CB1 receptors with IC50 values of 631 ±98 nM, and 690 ± 41 nM, respectively. LH-21 acted as an inverse agonist in a cAMP functional assay using cultured cells expressing human, rat or mouse CB1 receptor. In addition, in CHO cells overexpressing CB1, LH-21 was able to elevate cAMP, further confirming that LH-21 acted as an inverse agonist of CB1 in this model [1].

In vivo: Animal study showed that when given acutely LH-21 could decrease food intake and enhance the anorectic actions of oleoylethanolamide, a feeding suppressant lipid acting on peripheral sensory terminals in a similar way as rimonabant. However, unlike rimonabant, chronic administration of LH-21 at 3 mg/kg was able to reduce feeding but did not improve hypercholesterolaemia or hypertriglyceridaemia; nor did it reduce liver fat deposits in Zucker rats [2].

Clinical trial: So far, no clinical study has been conducted.
