The strong therapeutic potential of CB2 receptor agonists for use as anti-inflammatory agents that lack psychiatric side effects has attracted substantial interest. We herein describe the rational design and synthesis of novel thiazole and benzothiazole derivatives and the evaluation of their binding affinity and functional activity on CB1 and CB2 receptors. The series with the general formula N-(3-pentylbenzo [d]thiazol-2(3H)-ylidene) carboxamide (compounds 6a-6d) exhibited the highest affinity and selectivity towards CB2 receptors with Kis in the picomolar or low nanomolar range, and selectivity indices (Ki hCB1/Ki hCB2) reaching up to 429 fold. Notably, these compounds also demonstrated an agonistic functional activity in cellular assays with EC50s in the low nanomolar range. More interestingly, compound 6d, the 3-(trifluoromethyl)benzamide derivative, exhibited remarkable protection against DSS-induced acute colitis in mice model.

A series of (imidazolylmethyl)oxazoles and -thiazoles were prepared and evaluated as α2 adrenoceptor agonists. These compounds were also tested in in vivo paradigms that are predictive of analgesic activity. Variations in both the imidazole and thiazole portions of the molecule were investigated. Some of the more potent compounds such as 22, 26, 45, and 53 displayed α2 receptor binding in the 10-20 nM range and also had significant antinociceptive activity in the mouse abdominal irritant test (MAIT).
