Muscarinic agonists

Dioxolane is a heterocyclic acetal with the chemical formula (CH2)2O2CH2. It is related to tetrahydrofuran (THF) by replacement of the methylene group (CH2) at the 3-position with an oxygen atom. The corresponding saturated 6-membered C4O2 rings are called dioxanes. The isomeric 1,2-dioxolane (wherein the two oxygen centers are adjacent) is a peroxide. 1,3-dioxolane is used as a solvent and as a comonomer in polyacetals.

activating agent of the muscarinic acetylcholine receptor

Tazomeline (LY-287,041) is a drug which acts as a non-selective muscarinic acetylcholine receptor agonist. It was in clinical trials for the treatment of cognitive dysfunction such as that seen in Alzheimer's disease and schizophrenia, but development was apparently scrapped for unknown reasons. Another of the patented uses is for the treatment of "severe painful conditions".
