Behavioral studies of chronic CB(1) receptor activation may provide a pharmacological approach to understanding efficacy-related differences among CB(1) ligands as well as mechanistic commonalities between cannabinoid and noncannabinoid drugs. In the present studies, the effects of CB(1) agonists [(6aR,10aR)-3-(1-adamantyl)-6,6,9-trimethyl-6a,7,10,10a-tetrahydrobenzo[c]chromen-1-ol (AM411), 9β-...
A novel ionic liquid (IL) supported, green synthetic protocol has been developed toward the synthesis of oxo and thio hydantoin analogues tethered with tetrahydro-beta-carboline by the use of focused microwave irradiation. IL-bound tryptophan underwent a Pictet-Spengler reaction with various carbonyl compounds to generate the IL-immobilized tetrahydro-beta-carbolines in aqueous isopropanol medi...
Amongsuch compounds was included benarthin4'5), an inhibitor of pyroglutamyl peptidase (PGpeptidase). Wehave further continued screening for inhibitors of PG-peptidase, and discovered another new inhibitor, which we named pyrizinostatin, from culture filtrate of the microbial strain SA2289, which had been isolated from a marine soil and confirmed to belong to the genus Streptomyces. The structu...
an electroorganic reaction for the synthesis of 7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1h-pyrano[2, 3-d] pyrimidine-6-carbonitrile and ethyl-7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1h-pyrano[2, 3-d] pyrimidine-6-carboxylate derivatives are described, using an electrogenerated base of the anion of malonitrile or ethylcyanoacetate. this one-pot, three-component condensation of an a...
Two new polyketides: 2Z-(heptadec-12-enyl)-4-hydroxy-3,4,7,8-tetrahydro-2H-chromen-5(6H)-one (1) and 2-(heptadec-12-enyl)-5-hydroxy-5,6,7,8-tetrahydrochromen- 4-one (2), together with eleven known compounds: 4-hydroxy-2-[(3,4-methylenedioxy- phenyl)tridecanoyl] cyclohexane-1,3-dione (3), oleiferinone (4), 4-hydroxy-2-[(3,4- methylenedioxyphenyl)undecanoyl]cyclohexane-1,3-dione (5), 4-hydroxy-2-...
Retinoids regulate various aspects of vertebrate development through the action of two types of receptors, the retinoic acid receptors (RARs) and the retinoid-X-receptors (RXRs). Although RXRs bind 9-cis-retinoic acid (9cRA) with high affinity, in vitro experiments suggest that RXRs are for the most part not liganded, but serve as auxiliary factors forming heterodimers with liganded partner rec...
