Solid and solution phase synthesis of α-keto amides via azetidinone ring-opening: Application to the synthesis of poststatin
摘要:
3,3-Diethoxy-N-sulfonyl and carbamoyl azetidin-2-ones undergo efficient ring-opening reaction with various amine nucleophiles. Subsequent acid hydrolysis of the ketal moiety generated alpha-keto amides in excellent overall yields. The naturally occurring serine protease inhibitor poststatin was synthesized using this ring-opening reaction as the key step. (C) 1999 Elsevier Science Ltd. All rights reserved.

(EN) An analog of the peptide consisting of RPPGF is provided. Mimetics of RPPGF and its retropeptide, FGPPR, are also provided. A peptide is provided having an antikinin activity and having the sequence X1-R-P-P-G-F-X2, X1-F-G-P-P-R-X2. Provided are methods of screening for a mimetic or analog of RPPGF or FGPPR, screening for an RPPGF receptor, or screening for an antagonist of RPPGF or FGPPR is provided. Methods of treating conditions that can be treated by an antikinin activity and diseases that are associated with an antikinin activity are also provided.(FR) L'invention concerne un analogue du peptide consistant en RPPGF, ainsi que des mimétiques de RPPGF et de son rétropeptide, FGPPR. L'invention concerne également un peptide possédant une activité antikinine et présentant la séquence X1-R-P-P-G-F-X2, X1-F-G-P-P-R-X2; ainsi que des procédés de criblage d'un mimétique ou d'un analogue de RPPGF ou FGPPR, d'un récepteur de RPPGF, ou d'un antagoniste de RPPGF ou de FGPPR. L'invention concerne enfin des procédés de traitement de troubles pouvant être traités par une activité antikinine et de maladies associées à une activité antikinine.
