Enantioenriched amino acids are produced in a hydrolytic kinetic resolution of racemic aminonitriles mediated by chiral pentose sugars. Experimental kinetic and spectroscopic results combined with DFT computational studies and microkinetic modeling help to identify the nature of the intermediate species and provide insight into the stereoselectivity of their hydrolysis in the prebiotically relevant ribose-alanine system. These studies support a synergistic role for sugars and amino acids in the emergence of homochirality in biological molecules.

6-position modified decapeptide LHRH antagonists
-
, (2008/06/13)
The present invention provides a class of decapeptide compounds which are potent antagonists of LHRH activity and which have the structure A1 -D2 -E3 -G4 -J5 -L6 -M7 -Q8 -R9 -T10. The compounds of the percent invention are characterized by having an Ω-amino-functionalized side chain on the D-aminoacyl residue at position 6. The Ω-amino group of this side chain is further derivatized by the attachment of an extending group which likewise has a terminal amino group which is capped by an acyl group.

La pronase immobilisee sur poly(N-acryloylpiperidin-4-one): un catalyseur d'hydrolyse L-enantiospecifique des α-aminonitriles

Pronase immobilized on poly(N-acryloylpiperidin-4-one) : a L-enantiospecific hydrolysis of α-aminonitriles with immobilized amidase. α-Aminonitriles are not substrates for pronase (an amidase) in the homogeneous phase but become substrates for pronase when it is immobilized on polymer matrix with ketonic sites (piperidin-4-one).In this paper we show that under low basic aqueous conditions (pH 10-11), the hydration of α-aminonitriles can be efficiently catalyzed by poly(N-acryloylpiperidin-4-one) crosslinked with 1,4-bis acryloylpiperazine (A(80:20)) in the presence of phosphate or borate buffers.These conditions comply with the hydrolysis of α-aminoamides by pronase immobilized on poly(N-acryloylpiperidin-4-one)crosslinked with 1,4-bis(acryloyl)piperazine (A(80:20/p).Thus, in a buffered borate solution at pH 10.5, α(DL)-aminonitrile is enantiospecifically hydrolyzed into α(D)-aminoamide and α(L)-amino acid. Key words: α-aminonitriles / α amino acids / L-enantiospecific hydrolysis / polymer-supported catalysis / nitrilasic activity
