After extensive synthetic efforts, we found that many structurally diverse bioisosteres could be generated via derivatizing the C-4 alkyl chain on the pyrazole ring of compound 3 (B/P = 1/33) with different electronegative groups. Especially when a sulfonamide or sulfamide moiety was added,
S6K1 (p70 S6 kinase-1) is thought to play a critical role in the development of obesity and insulin resistance, thus making it an attractive target in developing medicines for the treatment of these disorders. We describe a novel thiophene urea class of S6K inhibitors. The lead matter for the
Serotonin N-acetyltransferase (arylalkylamine N-acetyltransferase, AANAT) is the penultimate enzyme in melatonin (5-methoxy-N-acetyltryptamine) biosynthesis. It is the key-enzyme responsible of the nocturnal rhythm of melatonin production in the pineal gland. Specific AANAT inhibitors could be
OBJECTIVE
Sterol-regulatory element binding proteins (SREBPs) are major transcription factors that regulate liver lipid biosynthesis. In this article we reported a novel synthetic compound 2-(3-benzoylthioureido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylic acid (ZJ001) that inhibited the
Melanin-concentrating hormone receptor antagonists containing thieno- and a benzopyridazinone cores were designed and tested as potential anorectic agents. These ligands showed high affinity for the receptor, potent functional activity in vitro, and good oral bioavailabilty in rats. The thiophene
Interstitial cells of Cajal, which express the calcium-activated chloride channel transmembrane member 16A (TMEM16A), are an important determinant of gastrointestinal (GI) motility. We previously identified the acylaminocycloalkylthiophene class of TMEM16A inhibitors, which, following medicinal
The present studies were conducted to determine the antiobesity effects of a novel inhibitor of hepatic fatty acid synthesis, 4-amino-5-ethyl-3-thiophene-carboxylic acid methyl ester hydrochloride (Ro 22-0654/001). Weight gain was decreased by treatment with Ro 22-0654 in Sprague Dawley and in lean
Melanin-concentrating hormone (MCH) is an attractive target for antiobesity agents, and numerous drug discovery programs are dedicated to finding small-molecule MCH receptor 1 (MCHR1) antagonists. We recently reported novel pyridine-2(1H)-ones as aliphatic amine-free MCHR1 antagonists that
Type 2 diabetes has become a pervasive public health problem. The etiology of the disease has not been fully defined but appears to involve abnormalities in peripheral and central nervous system pathways, as well as prominent inflammatory components. Because nicotinic acetylcholine receptors
Lipid droplets (LDs) are multi-functional organelles with the storage of lipid and participating in a variety of physiological processes, including membrane transport and signal transduction. The dysfunction of LDs has been reported to be associated with multiple diseases such as obesity, diabetes,
OBJECTIVE
Peroxisome proliferator-activated receptor gamma (PPARgamma) is a therapeutic target for obesity, cancer and diabetes mellitus. In order to develop potent lead compounds for obesity treatment, we screened a natural product library for novel PPARgamma antagonists with inhibitory effects on
