The synthesis and development of a novel class of mols. that inhibit anthrax edema factor, an adenylyl cyclase, is reported. These mols. are derived from the initial discovery that histidine and imidazole adducts of the prostaglandin PGE2 reduce the net secretory response of cholera toxin-challenged mice and act directly on the action of anthrax edema factor, a calmodulin-dependent adenylyl cyclase. The simple enones examined in this letter were prepared by palladium-catalyzed Suzuki reaction.

Compound: 2-Bromopropanenitrile, is researched, Molecular C3H4BrN, CAS is 19481-82-4, about Quantitative structure-reactivity modeling of copper-catalyzed atom transfer radical polymerization. Author is di Lena, Fabio; Chai, Christina L. L..

The authors present the first successful application of in silico modeling to the construction of quant. and predictive relationships between the set of constants kact, kdeact and KATRP and the structures and properties of various ATRP catalysts and initiators. The results are consistent not only with the generally accepted ATRP mechanistic picture but also provide valuable insights into this complex polymerization reaction. The models, built using the genetic function approximation algorithm, highlight and quantify the pivotal roles played in the ATRP process by energetic and steric factors of both catalysts and initiators as well as by the reaction medium. Moreover, the models suggest the existence of long-range interactions in catalyst-initiator recognition and subsequent binding. The authors believe that the approach will prove to be a powerful tool for the discovery of improved catalysts for ATRP.

A series of tacrine – benzothiazole hybrids incorporate inhibitors of acetylcholinesterase (AChE), amyloid β (Aβ) aggregation and mitochondrial enzyme ABAD, whose interaction with Aβ leads to mitochondrial dysfunction, into a single mol. In vitro, several of 25 final compounds exerted excellent anti-AChE properties and interesting capabilities to block Aβ aggregation. The best derivative of the series could be considered I that was found to be highly potent and selective towards AChE with the IC50 value in nanomolar range. Moreover, the same drug candidate exerted absolutely the best results of the series against ABAD, decreasing its activity by 23% at 100μM concentration Regarding the cytotoxicity profile of highlighted compound, it roughly matched that of its parent compound 6-chlorotacrine. Finally, I was forwarded for in vivo scopolamine-induced amnesia experiment consisting of Morris Water Maze test, where it demonstrated mild precognitive effect. Taking into account all in vitro and in vivo data, highlighted derivative I could be considered as the lead structure worthy of further investigation.

High performance polyacrylonitrile (PAN) was prepared with Mg powder as both reducing agent (RA) and supplemental activator (SA) by single electron transfer-living radical polymerization (RASA SET-LRP). First-order kinetics of polymerization with respect to monomer concentration, linear increase of mol. weight, and narrow polydispersity with monomer conversion, and the obtained high isotacticity PAN indicate that RASA SET-LRP in the presence of Mg powder could simultaneously control mol. weight and tacticity of PAN compared with that obtained with ascorbic acid (VC) as RA.
