Serotonin antagonist reuptake inhibitor (SARI) drugs that block both 5-HT(2) receptors and the serotonin transporters have been developed. The human 5-HT(2A/2C) receptor has been implicated in several neurological conditions, and potent selective 5-HT(2A/2C) ligands may have therapeutic potential for treatment of CNS diseases such as depression. An(More)
Novel C-aryl glucoside SGLT2 inhibitors containing the thiazole motif were designed and synthesized for biological evaluation. Among the compounds assayed, thiazole containing furanyl moiety 14v and thiophenyl moiety 14y demonstrated the best in vitro inhibitory activity against SGLT2 in this series to date (IC50 = 0.720 nM for 14v and IC50 = 0.772 nM for(More)
Since the CB1 cannabinoid receptor antagonist 1 (SR141716, rimonabant) was previously reported to modulate food intake, CB1 antagonism has been considered as a new therapeutic target for the treatment of obesity. In the present study, biarylpyrazole analogues based on a pyrazole core coupled with 1,3,4-oxadiazole were synthesized and tested for CB1 receptor(More)
Arylpiperzine-containing pyrrole 3-carboxamide derivatives were synthesized and evaluated as novel antidepressant compounds. The various analogues were efficiently prepared and bio-assayed for binding to 5-HT(2A), 5-HT(2C) receptor, and 5-HT transporter. Based on their in vitro and in vivo activities as well as selectivity over other neurotransmitter(More)
Cannabinoid CB1 receptors have been the focus of extensive studies since the first clinical results of rimonabant (SR141716) for the treatment of obesity and related metabolic disorders were reported in 2001. To further evaluate the properties of CB receptors, we have designed a new series of tetrazole-biarylpyrazoles. The various analogues were efficiently(More)
Novel C-aryl glucoside SGLT2 inhibitors containing 1,3,4-thiadiazole moieties were designed and synthesized. Among the compounds tested, biaryl-type compounds containing pyrazine 59, 2-furan 61, and 3-thiophene 71 showed the best in vitro inhibitory activities to date (IC(50) = 3.51-7.03 nM) against SGLT2. A selected compound 61, demonstrated reasonable(More)
The hypothalamic-pituitary-adrenal (HPA) axis is the primary endocrine system to respond to stress. The HPA axis may be affected by increased level of corticotrophin-releasing factors under chronic stress and by chronic administration of monosodium glutamate (MSG). The purpose of this study was to investigate whether chronic MSG administration aggravates(More)
5-HT(3A) receptor antagonists have been used mainly for the treatment of nausea and vomiting. These days, the antagonists are of special interest due to their therapeutic potential to treat other diseases such as depression, psychotic disorder, drug abuse, and irritable bowel syndrome. To discover novel 5-HT(3A) receptor antagonists, we screened our(More)
A myriad of research groups have been engaged in searching for novel CB1 receptor antagonists, since SR141716A (rimonabant), a CB1 receptor antagonist, was discovered for an obesity treatment. In this research, extended series, based on the 1,5-diarylpyrazole template of rimonabant, was synthesized and tested for CB1 receptor binding affinity. In the(More)
T-type calcium channel is one of therapeutic targets for the treatment of cardiovascular diseases and neuropathic pains. Since the withdrawal of mibefradil, a T-type calcium channel blocker, there have been a lot of efforts to develop T-type calcium channel blockers. A small molecule library of dioxoquinazoline carboxamide derivatives containing 155(More)
