    "abstract": "GPR84 is an orphan GPCR that is expressed primarily in immune cells such as neutrophils and macrophages, and that modulates immune responses during inflammation. The receptor has appeared as a promising drug target, and accumulating evidence indicates that GPR84 inhibition is a viable approach for treatment of various inflammatory and fibrotic disorders. Herein, we report the discovery of a minor structural modification resulting in functional switch of agonists to inverse agonists. Subsequent SAR explorations led to the identification of low-nanomolar potency inverse agonists and antagonists, as exemplified by TUG-2181 (",
