General description

The kinetics and mechanism of the gas-phase thermal decomposition of 2-methyl-1,3-dioxolane has been studied in a static system. The infrared spectra of solid, liquid and gaseous 2-methyl-1,3-dioxolane has been studied. Low-temperature ozonation of 2-methyl-1,3-dioxolane in acetone-d6, methyl acetate and tert-butyl methyl ether has been reported.

Low-temperature ozonation (-78 degrees C) of 2-methyl-1,3-dioxolane (1a) in acetone-d6, methyl acetate, and tert-butyl methyl ether produced both the corresponding acetal hydrotrioxide (3a, ROOOH) and the hemiortho ester (2a, ROH) in molar ratio 1:5. Both intermediates were fully characterized by

1. Muscarinic receptors mediating contraction of rabbit endothelium-denuded aorta have been characterized functionally, in vitro, using a range of antagonists (atropine, pirenzepine, methoctramine, himbacine, 4-diphenyl-acetoxy-N-methyl piperidine methiodide (4-DAMP) and para-fluoro-hexahydro-siladifenidol (p-F-HHSiD). 2. The non-selective muscarinic agonist, (+)cis-dioxolane, induced concentration-dependent contractions

This study was designed to determine if the antinociception produced by intrathecally (i.t.) administered muscarinic agonists in male Sprague-Dawley rats is mediated by an L-arginine/nitric oxide/cyclic GMP cascade. Seven days after implantation of intrathecal catheters, antinociception was produced with graded

The radioreceptor assay for acetylcholine (ACh) is based on the ability of the ACh to compete with the specific binding of [3H] cis-methyldioxolane to muscarinic receptors of rat cerebral cortex membranes. The technique described was used to measure ACh levels

Some compounds that inhibit acetylcholinesterase (AChE) activity compete directly with quinuclidinyl benzilate (QNB) binding, a muscarinic antagonist which binds to all subtypes equally, and with cis-methyldioxolane (CD), an agonist that binds with high affinity to the M2 subtype of muscarinic
