Glucagon-like peptide 1 (GLP-1) is a 30 or 31 amino acid peptide hormone that contributes to the physiological regulation of glucose homeostasis and food intake. Herein, we report the discovery of a novel class of 11 amino acid GLP-1 receptor agonist

The 3-nitro-2-pyridinesulfenyl (Npys) derivative of cysteine was prepared and used to facilitate the formation of an unsymmetrical disulfide bond. Since this derivative is stable in trifluoroacetic acid:CH2 Cl2 (1:1) and anhydrous hydrogen fluoride,

Tryptophan alkylation by resin-derived carbocations and formation of diketopiperazine are two major yield reducing side reactions observed in Fmoc/t-Bu based solid-phase peptide synthesis. With the development of a versatile silicon-based linkage age

Fmoc-Argw, w′(Boc)2-OH and Boc-Argw, w′(Cbz)2-OH were prepared in two steps: Guanylation of Cu(II)-ornithine complex at Nδ with N, N′bis-urethane protected derivatives of 1-guanylpyrazole, followed by Nα-protection using either 9-fluorenylmet

A new phosphitylating agent, compatible with the Fmoc/t-butyl strategy for the production of phosphotyrosine containing peptides was synthesized. Our results demonstrated that high yields and high purities of phosphotyrosine peptides can be obtained

Bis-urethane protected derivatives of 1-guanylpyrazole were prepared and found to readily react with relatively amines at room temperature to produce bis-protected guanidines in good yields. Simultaneous removal of both protecting groups from these p

A novel, more efficient and practical synthesis of the title compound, recently reported as a potent inhibitor of nitric oxide synthase is described. Reaction of (L)-ornithine with 1H-pyrazole-N-allyl-1-carboxamidine allowed facile isolation of the t
