These considerations have potential to account for the important observation that the LASSS-pretreatment displayed greater preventive effect on nitration of Y198 compared to Y250 (Figure 2b)
The proposed purpose is to help protect glutathione during digestion and facilitate delivery across biological membranes
The corresponding pharmacokinetic parameters are listed as follows: T max = 0.167 h, C max = 155 11.8 ng Eq./ml, AUC 0t = 4945 417 h ng Eq./ml, AUC 0 = 12956 2074 hng Eq./ml, average residence time (MRT 0-t ) of plasma total radioactivity = 33.2 1.03 h, and t 1/2 = 102 h (Table 9)
