SR 11302 is a retinoid-based, AP-1-selective transcription factor inhibitor that blocks AP-1 activity without activating retinoic acid response element (RARE)-mediated transcription[1]. AP-1 is a transcription factor dimer composed of proteins such as Jun/Fos, which regulates the expression of genes such as inflammation and proliferation by binding to the TRE sequence[2]. RARE serves as the cognate DNA element for the retinoic acid receptor (RAR)/retinoid X receptor (RXR) heterodimer, propagating classic retinoid signaling[3]. By silencing AP-1 while remaining inert toward RAR/RXR, SR 11302 retains anti-inflammatory and anti-proliferative efficacy yet avoids the dermal toxicity, teratogenicity, and resistance associated with conventional retinoids[4]. SR 11302 is commonly used in studies of inflammation, oncology, and AP-1–mediated signaling pathways[5-7].
In vitro, pretreating AGS gastric epithelial cells with SR 11302 (2μM; 2h) and then infecting cells with H. pylori for 24 or 48h suppressed both cell proliferation and expression of oncogene proteins β-catenin and c-Myc[7]. In hypoxia-treated human pulmonary artery endothelial cells (HPAECs), SR 11302(1μM; 1h) abolished the hypoxia-evoked rise in aldosterone by blocking c-Fos/c-Jun–driven StAR transcription[8].
In vivo, oral administration of SR 11302 (o.5 or 1mg/kg/day) for 11 days in Vldlr−/− mice reduced the total vascular lesion number by 48% and decreased the lesion size by 40%, without detectable signs of toxicity in mice, including no change in body weight[5].

| Cell experiment [1]: | |
Cell lines | Human gastric epithelial AGS cells |
Preparation Method | Human gastric epithelial cell line AGS (adenocarcinoma gastric, ATCC CRL 1739) and H. pylori (strain NCTC 11637) were obtained from the American Type Culture Collection. H. pylori was inoculated onto chocolate agar plates at 37°C under microaerophilic conditions using GasPakTM EZ Gas Generating Pouch Systems. Prior to infection, H. pylori were harvested and then suspended in antibiotic-free cell culture medium. H. pylori was added to cultured cells at a bacterium/cell ratio 50:1. AGS cells were treated with selective AP-1 inhibitor SR 11302 (2μM) for 2h before H. pylori infection and cultured for 24h (protein levels of oncogenes) and 48h (viable cell numbers). |
Reaction Conditions | 2μM; 2h |
Applications | SR 11302 suppressed both cell proliferation and expression of oncogene proteins β-catenin and c-Myc in H. pylori-infected Gastric epithelial AGS cells. |
| Animal experiment [2]: | |
Animal models | Vldlr+/− mice |
Preparation Method | Vldlr+/− (heterozygous) mice from The Jackson Laboratory (stock no. 002529) were crossed to generate homozygous and WT littermates. SR 11302 was dissolved in corn oil. Vldlr−/− pups were orally gavaged with SR 11302 or vehicle control (corn oil) at two doses (low dose 0.5mg/kg body weight and high dose 1mg/kg body weight) daily from P5 to P15. P16 retinas were collected for PCR and neovascularization analysis. |
Dosage form | 0.5 or 1mg/kg/day for 11 days; p.o. |
Applications | SR 11302 reduced the total vascular lesion number by 48% and decreased the lesion size by 40%, without detectable signs of toxicity in mice, including no change in body weight. |
