The discovery of a novel, selective and fully efficacious CB2 agonist with satisfactory pharmacokinetic and pharmaceutical properties is described. Compound 6 was efficacious in a rat model of osteoarthritis pain following oral administration and, in contrast to morphine, maintained its analgesic effect throughout a 5-day subchronic treatment paradigm. These data were consistent with our hypothesis that full agonist efficacy is required for efficient internalization and recycling of the CB2 receptor to avoid tachyphylaxis. Based on its overall favorable preclinical profile, 6 (APD371) was selected for further development for the treatment of pain.

The synthesis and antifungal activity of 5- and 5'-6'-substituted azasordarin derivatives are described. Modification of the 5'-position led to the discovery of the spirocyclopentyl analogue 7g, which is the first azasordarin to register single-digit MIC values versus Aspergillus spp. Further investigation identified the 5'-i-Pr derivative 7b, which displays superior pharmacokinetic properties compared to other azasordarins.
