Note the chiral center is lost in the process. The effects are long lasting because these agents covalently bond to the proton pump, apparently irreversibly. The T1/2 of the parent drug in plasma is about 1-1.5 hours.The effects are longer lasting.: NC CO R HCOCHRHC H. .: : 40 a The ionic forms shown are those predominating at pH 7.0 although residue mass is given for the neutral compound The C Î± atoms, as well as those atoms marked with an asterisk, are chiral centers with configurations as indicated according to Fischer projection formulas.
