May 22, 2021 · Esters are neutral compounds, unlike the acids from which they are formed. In typical reactions, the alkoxy (OR′) group of an ester is replaced by another group. One such reaction is hydrolysis, literally “splitting with water.”. The hydrolysis of esters is catalyzed by either an acid or a base.
These reactive, cationic polymers are stable at low pH in water, but undergo a fast and selective degradation at higher pH to liberate neutral diketopiperazines. Related materials incorporating oligo(α-amino ester)s have been shown to be effective gene delivery agents, as the charge-altering degradative behavior facilitates the delivery and ...
Jun 1, 2023 · As shown in Fig. 1, when a large excess of PNPH (200 μM) was added to the pH 7 aqueous buffer, MINP ( 5+6a) and MINP ( 7+6a) at 0.30 μM was able to hydrolyze ∼550 and 585 equivalents of the ester at 400 min. Meanwhile, the amount of hydrolysis in buffer or in the presence of NINP was minimal (and is nearly overlapping in Fig. 1 ).
