Description
Sources: http://www.athenstaedt.de/download/Product_Information_Chlorobutanol.pdf

Chlorobutanol, or trichloro-2-methyl-2-propanol, is an analgesic and sedative hypnotic in man, and an experimental general anesthetic. It has antibacterial and antifungal properties. It is also used chemical preservative for parenteral drugs. It was found, that chlorobutanol inhibited mammalian Nav 1.2 channels at concentrations less than those used to preserve parenteral solutions. Its mechanism of inhibiting Na channels differs from that of local anesthetics in that it does not show use dependent or state dependent inhibition.

It was examined chlorobutanol effect on on exocrine response and intracellular Ca2+ dynamics in isolated pancreatic acini of the rat. Chlorobutanol (1 mg ml-1) markedly inhibited the secretory response to cholecystokinin octapeptide (CCK-8), carbamylcholine chloride (carbachol), or sodium fluoride, a direct G-protein activator. However, chlorobutanol itself induced a maximal release of amylase when the dose was increased to 4 mg ml-1. Chlorobutanol inhibited 13 pM [125I]-CCK-8 or 0.5 nM [3H]-methylscopolamine chloride binding to the acinar cells in a dose-dependent manner. These results indicate that chlorobutanol produces discernible pharmacological effects on the secretory response in rat pancreatic acinar cells through changes in the Ca2+ dynamics.
