Telenzepine is athienobenzodiazepine acting as selectiveM1antimuscarinic. It is used in the treatment of peptic ulcers.[1] Telenzepine isatropisomeric, in other words the molecule has a stereogenic C–N-axis. In neutral aqueous solution it displays a half-life for racemization of the order of 1000 years. The enantiomers have been resolved. The activity is related to the (+)-isomer which is about 500-fold more active than the (–)-isomer at muscarinic receptors in the rat cerebral cortex.[2]
