Use of an internal reference for the quantitative HPLC-UV analysis of solid-phase reactions: A case study of 2-chlorotrityl chloride resin

Here we evaluated the use of internal reference compounds for the rapid assessment of reactions performed in solid-phase. An internal reference compound (commercially available) was bound to the resin, together with the substrate, and cleaved with the products after completion of the reaction. The peak area of the reference compound in the HPLC-UV chromatograms can be correlated directly with those of other compounds present in the reaction mixture, thereby allowing a quantitative interpretation of the chromatograms with respect to conversion and yield. The usefulness of this method was demonstrated by optimization of a protocol for the synthesis of proline-based tripeptides.

Differences in the hydrolysis of enkephalin congeners by the two domains of angiotensin converting enzyme

The hydrolysis of enkephalin (Enk) congeners by the isolated N- (N-ACE) and C-domain of angiotensin I converting enzyme (ACE) and by the two-domain somatic ACE was investigated. Both Leu5- and Met5-Enk were cleaved faster by the C-domain than by N-ACE; rates with somatic ACE were 1600 and 2500 nmol/min/nmol enzyme with both active sites being involved. Substitution of Gly2 by D-Ala2 reduced the rate to 1/3rd to 1/7th of that of the Enks. N- ACE cleaved Met5-Enk-Arg6-Phe7 faster than the C-domain, probably with the highest turnover number of any naturally occurring ACE substrate (7600 min- 1). This heptapeptide is also hydrolyzed in the absence of Cl-, but the activation by Cl- is unique; Cl- enhances the hydrolysis of the heptapeptide by N-ACE but inhibits it by the C-domain, yielding about a 5- fold difference in the turnover number at physiological pH. This difference may result in the predominant role of the N-domain in converting Met5-Enk- Arg6-Phe7 to Enk in vivo.
