| Using molecular docking calculations, it is predicted that SUCNR1 may interact with gamma-hydroxybutyrate [12]. | ||||||||||||||||||||||

| Antagonist Comments | ||||||||||||||||||||||||||||||||||||||||||
| There are several synthetic antagonists against SUCNR1 discovered from a systematic structure-activity relationship study [3]. Among these antagonists, N-[{3-(3-trifluoromethyl-4-fluorophenyl)isoxazol-5-yl}methyl]-4-([1,8]naphthyridin-2-yl)butyramide (5g) and 2-{4-[5-(3-Chloro-4-trifluoromethoxyphenyl)-[1,3,4]oxadiazol-2-yl]butyl}-[1,8]naphthyridine (7e) are identified to have high pharmaceutical and clinical importance. 5g demonstrated satisfactory oral bioavailability in rats (%F: 26), very good plasma concentration (Cmax: 37uM, AUC0-24h: 69uM at 30mg/kg p.o. dose) and low plasma clearance. Similarly, 7e demonstrates low plasma clearance (2.0mL/min/kg), excellent bioavailability (%F: 87) and drug exposure (Cmax: 72uM, AUC0-24h: 471uMh, t1/2: 3.4h) upon oral admistration (30mg/kg p.o.) in rats. | ||||||||||||||||||||||||||||||||||||||||||

| Tissue Distribution Comments | ||||||||
| No transcripts of SUCNR1 were detected in the brain when examined by Northern blot analysis [4]. SUCNR1 is functionally expressed by immature dendritic cells after differentiation from monocytes and was rapidly downregulated after dendritic cell maturation [14]. SUCNR1 expression is enriched in both early and late-stage haematopoietic progenitor cells [7]. | ||||||||

| Gene Expression and Pathophysiology Comments | |
| The signalling of SUCNR1 is involved in various pathologies, such as renal hypertension, diabetic nephropathy, retinal angiogenesis, diabetic retinopathy and aggregation of platelets [2-3]. SUCNR1 signalling may also contribue to the formation of fibrosis [2]. |
| General Comments |
| SUCNR1 is a plasma membrane receptor that responds to extracellular succinate [2] SUCRN1 is a novel potential drug target to prevent renal complications of diabetes [16]. The expression of SUCNR1 in retinal pigment epithelium cells is iron-dependent [6]. |
