30 selenoglycolicamides and evaluated their potential anti-Leishmanial activity (L. amazonensis and L. donovani) through ligand- and structure-based virtual screening. A diverse set selected from the ChEMBL databanks of 818 structures (L. donovani) and 722 structures (L. amazonensis), with tested anti-Leishmanial activityagainst promastigotes forms were classified according to pIC50 values to generate

The copper-catalyzed highly regio- and stereoselective 1,1-dicarbofunctionalization of terminal alkynes is realized for the first time. Using a removable, bidentate 8-aminoquinoline auxiliary, the three-component, selective 1,1-arylalkylation of alkynes with α-haloacetamides and organoboronic acids by the addition of both alkyl and aryl groups to the terminal carbon of alkynes was achieved. Mechanistic

Various new N-aryl oxindoles were synthesized as intermediates for the preparation of pharmacologicallyactive 2-(N-arylamino)-phenylacetic acids. Two novel approaches were explored for the construction of diarylamine and N-aryl oxindole core structures, in addition to Buchwald-arylamination and Smiles rearrangement. Condensation of anilines with 2-oxo-cyclohexylidene-acetic acid derivatives and subsequent

in isolation of the intermediate enethiolate derivative, thereby reducing quantity of the α-haloketone to one molar equivalent. Moreover, the reaction conditions were optimized to attain optimum base/solvent combination to improve the yield of the target derivatives. Following our modified procedure, three series of new 3-amino-4-cyanothiophene derivatives were synthesized and isolated in high yields
Potent and reversible: Dithiobisacetamides were determined to be urease inhibitors that function through a mechanism of mixed inhibition. They showed excellent potency against Helicobacter pylori urease and good antibacterial activity with nearly no cytotoxicity. The impressive biological profile of d8 (shown) underscores its suitability for further development as a therapeutic agent to tackle infections
