Success in discovering bioactive peptide mimetics is often limited by the difficulties in correctly transposing known binding elements of the active peptide onto a small and metabolically more stable scaffold while maintaining bioactivity. Here we describe a scanning approach using a library of pyranose-based peptidomimetics that is structurally diverse in(More)
Few reported inhibitors of secretory phospholipase A(2) enzymes truly inhibit the IIa human isoform (hnpsPLA(2)-IIa) noncovalently at submicromolar concentrations. Herein, the simple chiral precursor D-tyrosine was derivatised to give a series of potent new inhibitors of hnpsPLA(2)-IIa. A 2.2-A crystal structure shows an inhibitor bound in the active site(More)
In this paper, we present an account of in virtue of what thinkers are justified in employing certain basic belief-forming methods. The guiding idea is inspired by Reichenbach's work on induction. There are certain projects in which thinkers are rationally required to engage. Thinkers are epistemically justified in employing a belief-forming method that is(More)
In the following I discuss the debate between epistemological internalists and externalists from an unfamiliar meta-epistemological perspective. In doing so, I focus on the question of whether rationality is best captured in externalist or internalist terms. Using the idea of epistemic judgments as " doxastic plans " , I characterize one important(More)
An efficient method for preparing conformationally restricted cyclopentenyl-glutamate analogues in a regioselective and diastereoselective manner has been developed using a formal [3 + 2] cycloaddition reaction of dehydroamino acids. Methods for preparing optically active versions of these compounds have also been devised. Of these compounds, (S)-2 is an(More)
