WebSep 19, 2024 · Thiol levels increased in a time-dependent manner which indicates labile disulfide bond reduction (figure 5 a). This increase in cell surface thiols is greater in an MLR relative to an autologous reaction ( figure 5 b ). WebApr 10, 2024 · A nucleophilic attack of the thiol of one unit on the nitrile group of a second unit is the starting point. Then, the amine adds onto the obtained iminium double bond in 13 to form a transient thiazolidine 14, which, upon NH 3 loss, gives the more stable thiazoline cycle 15. This thiazoline is then slowly hydrolyzed to give dipeptide 16.
