-based glyoxalaseIinhibitors culminated in the discovery of the first single-digit nanomolar inhibitor. This study makes available key information about possible means to address the issues of metabolic instability, low potency, and synthetic complexicity that have plagued the area of glyoxalaseI inhibition. Knowledge garnered from this study has implications in the design of inhibitors with higher

The syntheses of gamma-linked L-D, D-D, and D-L dipeptide analogues of 2-desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583) are described. The general methodology for the synthesis of these molecules involved the preparation of the dipeptide derivatives employing solution phase peptide synthesis followed by condensation of the dipeptide free bases with the appropriate pteroic acid analogue
Synthese des immunspezifischen, polypeptid-artigen haptens der anthrax-subtilis bacillengruppe. Ein synthetischer beweis der konstitution der natürlichen polyglutaminsäuren
We have designed, synthesized, and tested in vitro a novel class of noncovalentthrombininhibitors. The main feature of these inhibitors is a 6,5-fused bicyclic core structure that fills the S2 pocket of the activesite of thrombin. The bicycle introduces conformational constraint into the ligand and locks the Xaa-Pro amide bond into the desired trans configuration. Among the known ring systems, we

Novel glucosamine-peptide derivatives of the formula: ##STR1## wherein m is 0 or 1; n is 0 or an integer of 1 to 9; R is lower alkyl which may be substituted with hydroxyl, or aryl; R.sup.1 is hydrogen or acyl having an acyclic hydrocarbon group, the terminal of which may be substituted with a cyclic hydrocarbon group directly, via a carbonyl group or via an oxygen atom; provided that when R.sup.1 is hydrogen m is 1; R.sup.2 is hydrogen or lower alkyl which may form a ring by connecting its terminal with the .alpha.-nitrogen atom when n is 0, or hydrogen when n is an integer of 1 to 9; R.sup.3 is hydrogen or lower alkyl; R.sup.4 and R.sup.5 are each hydrogen or lower alkyl which may be substituted with hydroxyl or benzyloxyl; R.sup.6 is hydrogen or lower alkyl; R.sup.7 is alkyl which may be substituted with lower alkoxyl or aralkyl; R.sup.8 and R.sup.9 are each hydrogen, lower alkyl or aralkyl; and (D) and (L) each indicate configurations if their respective carbon atoms are asymmetric; or an acid addition salt thereof, have immunostimulatory activity.
