Abstract
The Pipecolic linker is a new highly versatile handle which immobilizes on solid support through a carboxylic acid function a wide range of amines, alcohols, and hydrazines. The anchoring step on pipecolic resin is very easy and efficient, and compounds are released with high purities upon acidic treatment. During this treatment, an oxazolonium intermediate is hydrolyzed, yielding the cleavage of ester or amide bond and the release of free carboxylic acid of the starting linker. In this study, we report the possibility of recycling the pipecolic resin after the use of several trifluoroacetic acid (TFA) cleavage cocktails. We demonstrate that it can be reused up to five times without significant loading decrease.

Abstract
The design, synthesis, and potential application of the pipecolic linker is presented. This new versatile handle can immobilize primary, secondary, and aromatic amines, as well as alcohols, phenols, and hydrazides, on a solid support. Compared with other linkers, the anchoring step is easy and efficient. The release of final products from the resin proceeds upon acidic treatment with high purities. The pipecolic linker offers the promise of being using in peptide chemistry to produce peptides modified at the N and C terminus, peptidomimetics, as well as small organic molecules.

Abstract
The nonapeptide bradykinin (BK) is involved in the genesis of inflammation, edema and in pain mediation. As such, much effort has gone into the development of peptide/non-peptide antagonists to counteract these processes. However, there is an increasing awareness of the potential value of chemically stable BK agonists in the treatment of diabetes and cardiovascular diseases. In this study, a structure-activity relationship study of BK was performed to develop potent and stable peptide mimetics active at the human B2 receptors (hB2R). Twenty-three analogues were produced with substitutions at positions 1, 3, 5, 7, 8 and/or 9 of BK. In vitro binding (on transiently transfected HEK-293T cells) and biological activities (vasomotricity tests on human umbilical veins, MAPK assays on HEK-293T cells) of novel BK peptide derivatives at hB2R were determined alongside with previously reported synthetic agonists (e.g. RMP-7, JMV1609, FR190997). Some peptides were also tested in vivo in rats and rabbits using blood pressure assays. Two compounds, [Hyp(3), Thi(5), Cha(8)]-BK and [Hyp(3), Thi(5), (N)Chg(7), Thi(8)]-BK, exhibited equivalent (or even greater) in vitro affinities and potencies to BK at the naturally expressed and recombinant hB2R. Their potency and duration of action in vivo were highly superior to BK, thus inferring that they can withstand intravascular proteolysis. These novel compounds show promise as candidates for investigating the pharmacology of BK receptors and developing potential therapeutical applications.

Abstract
The purpose of this article is to delineate strategic considerations and provide practical procedures to enable non-experts to synthesize peptides with a reasonable chance of success. This article is not encyclopedic but rather devoted to the Fmoc/tBu approach of solid phase peptide synthesis (SPPS), which is now the most commonly used methodology for the production of peptides. The principles of SPPS with a review of linkers and supports currently employed are presented. Basic concepts for the different steps of SPPS such as anchoring, deprotection, coupling reaction and cleavage are all discussed along with the possible problem of aggregation and side-reactions. Essential protocols for the synthesis of fully deprotected peptides are presented including resin handling, coupling, capping, Fmoc-deprotection, final cleavage and disulfide bridge formation.

Abstract
The dramatic rise of antibiotic-resistant bacteria over the past two decades has stressed the need for completely novel classes of antibacterial agents. Accordingly, recent advances in the study of prokaryotic transcription open new opportunities for such molecules. This paper reports the structure-activity relationships of a series of phenyl-furanyl-rhodanines (PFRs) as antibacterial inhibitors of RNA polymerase (RNAP). The molecules have been evaluated for their ability to inhibit transcription and affect growth of bacteria living in suspension or in a biofilm and for their propensity to interact with serum albumin, a critical parameter for antibacterial drug discovery. The most active of these molecules inhibit Escherichia coli RNAP transcription at concentrations of </=10 microM and have promising activities against various Gram-positive pathogens including Staphylococcus epidermidis biofilms, a major cause of nosocomial infection.

Abstract
A pulse of short peptides, RGDS and DGEA in the millimolar range, immediately elicits in normal human fibroblasts a transient increase of intracellular Ca2+ ([Ca2+]i). In the present study, we show that this [Ca2+]i occurs in an increasing number of cells as a function of peptides concentration. It is specific of each peptide and inhibited at saturating concentration of the peptide in the culture medium. The [Ca2+]i transient depends on signalling pathways slightly different for DGEA and RGDS involving tyrosine kinase(s) and phosphatase(s), phospholipase C, production of inositol-trisphosphate and release of Ca2+ from the cellular stores. GFOGER, the classical collagen binding peptide of alpha1- alpha2- and alpha11-beta1 integrins, in triple helical or denatured form, does not produce any Ca2+ signal. The [Ca2+]i signalling induced by RGDS and DGEA is inhibited by antibodies against beta1 integrin subunit while that mediated by RGDS is also inhibited by antibodies against the alpha3 integrin. Delay in the acquisition of responsiveness is observed during cell adhesion and spreading on a coat of fibronectin for RGDS or collagen for DGEA or on a coat of the specific integrin-inhibiting antibodies but not by seeding cells on GFOGER or laminin-5. This delay is suppressed specifically by collagenase acting on the collagen coat or trypsin on the fibronectin coat. Our results suggest that free integrins and associated focal complexes generate a Ca2+ signal upon recognition of DGEA and RGDS by different cellular pathways.
