Disclosed are ionic liquids and methods of preparing ionic liquid compositions of active pharmaceutical, biological, nutritional, and energetic ingredients. Also disclosed are methods of using the compositions described herein to overcome polymorphism, overcome solubility and delivery problems, to control release rates, add functionality, enhance efficacy (synergy), and improve ease of use and manufacture.
Disclosed is a compound of formula (I) in which R1, R2, and R3 are as described herein. Also provided are pharmaceutical compositions comprising the compound of formula (I) and methods of using the compound of formula (I), including a method of treating a disease or disorder and a method for effectuating a G-protein coupled receptor (GPCR)-mediated response in a subject.
3-(Substituted-amino)-1,2,3,4-tetrahydrocarbazoles are prepared by reacting appropriate 4-substituted-aminocyclohexanones with a phenylhydrazine, by reacting a 3-(sulfonyloxy)-1,2,3,4-tetrahydrocarbazole with an appropriate substituted amine, or by reduction of an appropriate 3-(acylamino)-1,2,3,4-tetrahydrocarbazole. The 3-(substituted-amino)-1,2,3,4-tetrahydrocarbazoles of this invention have analgetic and psychotropic activities. Moreover, certain of these compounds also have antihistaminic activity.
