stemming from BP-HSA to be recognized by naı̈ve CD4+ T-cells thus identifying a pre-existing T-cell repertoire for penicillin molecules bound to proteins. It also established a promising model approach expandable to other most frequently used penicillin classes of antibiotics to reveal biomimetic drug-modified antigenic peptides relevant for qualitative and quantitative drug allergy studies.
of the peptide condensation methods termed thioester method, an amino protectinggroup is required in the lysine side chain. In this study, to investigate the efficiency of the pyruvoyl group as an amino protectinggroup, we synthesized Nα-fluorenylmethoxycarbonyl (Fmoc)-Nε-pyruvoyl-lysine and introduced it into peptides and glycopeptides by the ordinary Fmoc-based solidphasepeptidesynthesis.

Charting the reaction space around a known Multicomponent Reaction (MCR) allows the development of new processes. In this way, a detailed study of the parameters involved in the Orru transformation leads to the generation of alternative connectivities featuring diversely substituted imidazolones, including GFP (Green Fluorescent Protein) chromophores, coelenterazine derivatives, natural products, kinase

Murray Valley encephalitis is an infectious disease spread by a mosquito-borne virus endemic in Papua New Guinea and northern Australia. In the past decade, it has spread to various regions of Australia and there is currently no therapeutic treatment against this disease. An attractive drug target is the viral serine protease NS2B/NS3, a critical enzyme involved in viral replication. Herein, we report the inhibitory activities of 37 C-terminal agmatine peptidomimetic inhibitors which led to the design of a novel structurally-constrained competitive inhibitor 38 possessing a K-i of 2.5 +/- 0.5 mu M. We believe our data provides crucial insights into the viral protease active site specificity which could be used to facilitate drug design against Murray Valley encephalitis viral infections.
