In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. The reactant in an enzyme-catalyzed reaction is called a substrate. category: benzothiophene, C8H5BrS. A document type is Article, introducing its new discovery., category: benzothiophene

It was found that the C(sp)?B(dan) bond of alkynyl?B(dan)s can be directly used for palladium-catalyzed carbon?carbon bond-forming reactions with aryl(alkenyl) halides and allylic carbonates as electrophiles, thus delivering unsymmetrical internal alkynes and unconjugated 1,4-enynes, respectively. With acyl chlorides as electrophiles, ynone synthesis is also promoted by a palladium catalyst with the assistance of a copper co-catalyst. These reactions can be achieved as more convenient one-pot reactions, without isolating the alkynyl?B(dan) formed in situ by the zinc-catalyzed dehydrogenative borylation of alkynes with HB(dan). In addition to direct C(sp)?B(dan) bond transformations, the C?C bond in an alkynyl?B(dan) proved to be a promising scaffold for the construction of a multisubstituted alkene, which is synthesized by diboration of the C?C?B(dan) moiety, leading to a triborylalkene followed by iterative regio- and stereoselective Suzuki?Miyaura cross-coupling reactions. As one example, the synthesis of the ethene with four different aryl groups, p-MeC6H4, p-MeOC6H4, p-NCC6H4, and p-F3CC6H4, was attained in high overall yield of 64% in six steps starting from the terminal alkyne, p-MeC6H4C?CH. Besides these synthetic applications of the alkynyl?B(dan), the scope of the alkynyl substrate in the zinc-catalyzed dehydrogenative borylation was expanded to enhance the reliability as a provider of the alkynyl?B(dan). Consequently, 42 alkynes were found to participate in the dehydrogenative borylation as substrates; these are alkyl-, alkenyl-, aryl-, heteroaryl-, ferrocenyl-, silyl-, and borylalkynes, with or without a variety of functional groups. Lastly, a new method for preparing HB(dan), as a sulfide-free, cost-saving, and reaction-time-saving route, is disclosed. (Figure presented.).

The tropical diseases human African trypanosomiasis, Chagas disease, and the various forms of leishmaniasis are caused by parasites of the family of trypanosomatids. These protozoa possess a unique redox metabolism based on trypanothione and trypanothione reductase (TR), making TR a promising drug target. We report the optimization of properties and potency of cyclohexylpyrrolidine inhibitors of TR by structure-based design. The best inhibitors were freely soluble and showed competitive inhibition constants (Ki) against Trypanosoma (T.) brucei TR and T. cruzi TR and in vitro activities (half-maximal inhibitory concentration, IC50) against these parasites in the low micromolar range, with high selectivity against human glutathione reductase. X-ray co-crystal structures confirmed the binding of the ligands to the hydrophobic wall of the ?mepacrine binding site? with the new, solubility-providing vectors oriented toward the surface of the large active site.
