Obesity is a major clinical problem in the western world, and many molecular targets have been explored in the search for effective therapeutic agents. One of these, antagonism of the cannabinoid 1 (CB1) receptor, rose to prominence following reports demonstrating the positive modulation of food intake by the CB1 antagonist, rimonabant (3) (SR141716A). In the present study, various diaryl-pyrazole derivatives containing cycloalkyl building blocks were synthesized and tested for CB1 receptor binding affinities. Thorough structure-activity relationship (SAR) studies to optimize the pyrazole substituents led to several novel CB1 antagonists with K(i)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
