Talaglumetad (also known as LY-544344) is a bicyclohexane derivative patented by Eli Lilly and Company as modulators of metabotropic glutamate receptor. Talaglumetad acts as a prodrug of Eglumegad, a selective agonist of metabotropic glutamate receptors (mGluR2/3) and metabolized to release active compound by both human jejunal homogenates and rat liver homogenates. In experiments on mice, Talaglumetad was found to be as effective as diazepam for treating anxiety symptoms in several standard tests, but without producing any of the negative side effects of diazepam such as sedation and memory impairment.

Tarafenacin (also known as SVT-40776) was developed as muscarinic M3 receptor antagonist for the treatment of overactive bladder. The drug participated in phase II clinical trial in patients suffering from overactive bladder, where both dose levels of tarafenacin were well tolerated. However, information about the further development of tarafenacin is not available.
