Abstract

Although hematopoietic Prostaglandin D Synthase (H-PGDS) is an attractive target for treatment of a variety of diseases, including allergic diseases and Duchenne muscular dystrophy, no H-PGDS inhibitors have yet been approved for treatment of these diseases. Therefore, the development of novel agents having Other modes of action to modulate the activity of H-PGDS is required. In this study, a chimeric small molecule that degrades H-PGDS via the ubiquitin-proteasome system, PROTAC(H-PGDS)-1, was developed. PROTAC(H-PGDS)-1 is composed of two ligands, TFC-007 (that binds to H-PGDS) and pomalidomide (that binds to Cereblon). PROTAC(H-PGDS)-1 showed potent activity in the degradation of H-PGDS protein via the ubiquitin-proteasome system and in the suppression of prostaglandin D2 (PGD2) production. Notably, PROTAC(H-PGDS)-1 showed sustained suppression of PGD2 production after the drug removal, whereas PGD2 production recovered following removal of TFC-007. Thus, the H-PGDS degrader-PROTAC(H-PGDS)-1-is expected to be useful in biological research and clinical therapies.
