Design, synthesis, evaluation, and molecular docking of ursolic acid derivatives containing a nitrogen heterocycle as anti-inflammatory agents 10.1016/j.bmcl.2018.04.021 2018-04-11 Ursolic acid derivatives containing oxadiazole, triazolone, and piperazine moieties were synthesized in an attempt to develop potent anti-inflammatory agents. Structures of the synthesized compounds were elucidated by 1H NMR, 13C NMR, and HRMS. Most of the sy...
Covalent inhibitors of nicotinamide N-methyltransferase (NNMT) provide evidence for target engagement challenges in situ 10.1016/j.bmcl.2018.04.017 2018-04-10 Nicotinamide N-methyltransferase (NNMT) catalyzes the N-methylation of nicotinamide using S-adenosyl-L-methionine (SAM) as a methyl donor and, through doing so, can modulate cellular methylation potential to impact diverse epigenetic processes. NNMT has been ...

Synthesis of 3-(3-hydroxyphenyl)pyrrolidine dopamine D3 receptor ligands with extended functionality for probing the secondary binding pocket 10.1016/j.bmcl.2018.03.084 2018-04-04 A series of 3-(3-hydroxyphenyl)pyrrolidine analogues which incorporate N-alkyl groups and N-butylamide-linked benzamide functionality have been synthesized and their in vitro binding affinities at human dopamine receptors have been evaluated. Our ligand desig...
Structure-Activity Relationship Study of a Series of Caspase Inhibitors Containing γ-Amino Acid Moiety for Treatment of Cholestatic Liver Disease 10.1016/j.bmcl.2018.04.002 2018-04-04 A series of caspase inhibitors containing γ-amino acid moiety have been synthesized. A systemic study on their structure-activity relationship of anti-apoptotic cellular activity is presented. These efforts led to the discovery of compound 20o as a potent cas...
Photoactivated 2,3-Distyrylindoles Kill Multi-Drug Resistant Bacteria 10.1016/j.bmcl.2018.04.001 2018-04-03 Compounds based on the 2,3-distyrylindole scaffold were found to exhibit bactericidal properties upon irradiation with white light. At the concentration of 1 μM, the lead compound 1 completely (ca. 109 CFU/mL) eradicated such Gram-positive organisms as S. aur...
Stereospecific synthesis of (E)-stilbene derivatives by palladium-catalyzed Suzuki-Miyaura cross-coupling reaction 10.1016/j.bmcl.2018.04.004 2018-04-03 A general procedure for the stereospecific synthesis of (E)-stilbene derivatives by palladium-catalyzed Suzuki-Miyaura cross-coupling reaction of (E)-2-phenylethenylboronic acid pinacol ester with aryl bromides was investigated. (E)-2-phenylethenylboronic aci...
Identification and biological evaluation of thiazole-based inverse agonists of RORγt 10.1016/j.bmcl.2018.03.093 2018-04-03 The nuclear receptor retinoic acid receptor-related orphan receptor gamma t (RORγt) is a transcription factor that drives Th17 cell differentiation and IL-17 production in both innate and adaptive immune cells. The IL-23/IL-17 pathway is implicated in major a...
Discovery of Chiral Dihydropyridopyrimidinones as Potent, Selective and Orally Bioavailable Inhibitors of AKT 10.1016/j.bmcl.2018.03.092 2018-04-02 During the course of our research efforts to develop potent and selective AKT inhibitors, we discovered enatiomerically pure substituted dihydropyridopyrimidinones (DHP) as potent inhibitors of protein kinase B/AKT with excellent selectivity against ROCK2. A ...
