Compounds of the general formula (I):
wherein the variables are as defined in the specification are useful for the prophylaxis or treatment of serotonin-related, especially 5-HT2 receptor-related, diseases in human beings or animals, particularly diseases related to the 5-HT2c receptor, especially diseases such as eating disorders, memory disorders, schizophrenia, mood disorders, anxiety disorders, pain, sexual dysfunctionions, and urinary disorders.
Methods of treating disorders using compounds that modulate striatal-enriched tyrosine phosphatase (STEP) are described herein. Exemplary disorders include schizophrenia and cognitive deficit.
Herein we report our efforts of developing reversible selective hMAO-B inhibitorsbased on isatin, a fragment in an X-ray crystal structure. Five different scaffolds were designed and many compounds were synthesized. Among them, compound A3 demonstrated very high potency and isoform selectivity against hMAO-B, 11 and 13 times more potent (IC50 = 3 nM) and 23.64 and 6.8 times more selective than the
α‐Functionalization of ketones in an umpolung fashion can be achieved by nucleophilic addition to the oxy‐allylcation intermediate. However, applicable carbon nucleophiles are limited to ones with high nucleophilicity. Additionally, introduction of a leaving group to the α‐position of ketone substrates is required beforehand. Herein, we report the CuCl2‐mediated oxidative intramolecular α‐arylation

The present invention provides novel conformationally-defined macrocyclic compounds that have been demonstrated to be selective modulators of the ghrelin receptor (GRLN, growth hormone secretagogue receptor, GHS-R1a and subtypes, isoforms and/or variants thereof). Methods of synthesizing the novel compounds are also described herein. These compounds are useful as antagonists or inverse agonists of the ghrelin receptor and as medicaments for treatment and prevention of a range of medical conditions including, but not limited to, metabolic and/or endocrine disorders, obesity and obesity-associated disorders, appetite or eating disorders, addictive disorders, cardiovascular disorders, gastrointestinal disorders, genetic disorders, hyperproliferative disorders, central nervous system disorders and inflammatory disorders.
