N-[[(2S)-1-[[5-(4-fluorophenyl)-2-methyl-4-thiazolyl]carbonyl]-2piperidinyl]methyl]-4-benzofurancarboxamide (SB-649868) is a novel orexin 1 and 2 receptor antagonist under development for insomnia treatment. The disposition of [C]SB-649868 was determined in eight healthy male subjects using an open-label study design after a single oral dose of 30 mg. Blood, urine, and feces were collected at f...

Small-conductance (KCa2.1-2.3) and intermediate-conductance (KCa3.1) calcium-activated K(+) channels are critically involved in modulating calcium-signaling cascades and membrane potential in both excitable and nonexcitable cells. Activators of these channels constitute useful pharmacological tools and potential new drugs for the treatment of ataxia, epilepsy, and hypertension. Here, we used th...

The inner filter effect due to self-quenching dominates the normal emission of dyes at higher concentrations, which would limit their applications. Since normal emission was also observed with aggregation induced emission enhancement (AIEE) active excited state intramolecular proton transfer (ESIPT) exhibiting molecules, two new molecules are synthesized and studied to obtain normal emission fr...

Acetyl CoA carboxylase (ACC) 2, which catalyzes the carboxylation of acetyl-CoA to form malonyl-CoA, has been identified as a potential target for type 2 diabetes and obesity. Small-molecule inhibitors of ACC2 would be expected to reduce de novo lipid synthesis and increase lipid oxidation. Treatment of ob/ob mice with compound A-908292 (S) ({(S)-3-[2-(4-isopropoxy-phenoxy)-thiazol-5-yl]-1-meth...

BACKGROUND Isoxazoles exhibit interesting biological activities, and the 1,3-dipolar cycloaddition(13DC) reactions play an important role in both mechanistic and synthetic organic chemistry. Pyrazoles and annulated pyrazoles exhibit some diverse biological activities. They are used as antipyretic, analgesic drugs, tranquilizing, and herbicidal agents. Pyrazoles are also used extensively as usef...

The effect of the presence of titanium dioxide in two new imines, (E,E)-(butane-1,4-diyl)bis(oxybutane-4,1-diyl) bis(4-{[(benzo[d][1,3]thiazol-2-yl)methylidene]amino}benzoate) (SP1) and (E)-N-[(benzo[d][1,3]thiazol-2-yl)methylidene]-4-dodecylaniline (SP2), on the properties and stability of imine:TiO2 composites for organic device applications were examined. The investigated titanium dioxide (i...

The paucity of specific pharmacological agents has been a major impediment for delineating the roles of gap junction (GJ) channels formed by connexin proteins in physiology and pathophysiology. Here, we used the selective optimization of side activities (SOSA) approach, which has led to the design of high affinity inhibitors of other ion channels, to identify a specific inhibitor for channels f...

The current study examined the bioactivation potential of ghrelin receptor inverse agonists, 1-{2-[2-chloro-4-(2H-1,2,3-triazol-2-yl)benzyl]2,7-diazaspiro[3.5]nonan-7-yl}-2-(imidazo[2,1-b]thiazol-6yl)ethanone (1) and 1-{2-[2-chloro-4-(2H-1,2,3-triazol-2-yl)benzyl]-2,7diazaspiro[3.5]nonan-7-yl}-2-(2-methylimidazo[2,1-b]thiazol-6-yl) ethanone (2), containing a fused imidazo[2,1-b]thiazole motif i...
