A number of new and useful methodologies for the synthesis of vinylaziridines and ethynylaziridines have been developed. Vinylaziridines can be generally synthesized in two steps, with the vinyl group being constructed following formation of the aziridine ring. The addition of a nitrene equivalent to a conjugated diene is a traditional method for direct synthesis of aziridines. Reagent-controlled asymmetric induction for the synthesis of vinylaziridines was reported in 2000, where the reaction of oximes with a chloroallyl phosphonic diamide anion derived led to formation of cis-N-alkoxy-2-alkenylaziridines in a enantiomerically pure form. The strained aziridine ring at the reactive allylic/propargylic position provides efficient levels of reactivity toward a range of transformations, including stereoselective nucleophilic ring opening reactions, as well as rearrangement and cycloaddition reactions to yield a variety of nitrogen-containing molecules.

Nuclear factor-kappa B (NF-κB) is a transcription factor involved in a wide variety of phenomena including inflammation, immune responses, and cell survival. Abnormal activation of NF-κB occurs in many pathological conditions, such as allergic and auto-inflammatory diseases and malignancies. As a result, the signal-induced NF-κB activation pathway has been extensively studied and revealed to be regulated by ubiquitination. Several types of polyubiquitin chains exist and the type of chain seems to impact how ubiquitinated proteins are regulated. Recently, different types of polyubiquitin chains, including linear (M1) and K11 chains, have been implicated in NF-κB activation. This review discusses existing evidence of the differential roles played by various ubiquitin chains, particularly K63, M1, and K11 chains, in NF-κB activation. © 2012 Elsevier Ltd. Source

Recently, we saw a dramatic increase in the number of researches that rely on coarse-grained (CG) simulations for large biomolecules. Here, first, we briefly describe recently developed and used CG models for proteins and nucleic acids. Balance between structure-based and physico-chemical terms is a key issue. We also discuss the multiscale algorithms used to derive CG parameters. Next, we comment on the dynamics used in CG simulations with an emphasis on the importance of hydrodynamic interactions. We then discuss the pros and cons of CG simulations. Finally, we overview recent exciting applications of CG simulations. Publicly available tools and software for CG simulations are also summarized. © 2012 Elsevier Ltd. Source
