NX-13 is a first-in-class, orally active and gut-restricted agent that selectively targets and activates the NLRX1 pathway to induce immunometabolic changes. NX-13 results in lower inflammation and responses in inflammatory bowel disease. NX-13 can be used for the research of crohn’s disease and ulcerative colitis[1][2].
NX-13 (0, 500, or 1000 mg/kg; oral gavage; 7 days) reduces ALP levels[2].NX-13 (1 and 10 mg/kg; oral gavage; 0~24 hours) reaches the distal gastrointestinal tract[2].

Exploratory studies with NX-13: oral toxicity and pharmacokinetics in rodents of an orally active, gut-restricted first-in-class therapeutic for IBD that targets NLRX1
Drug Chem Toxicol 2022 Jan;45(1):209-214.PMID:31650868DOI:10.1080/01480545.2019.1679828.
Nucleotide-binding oligomerization domain, leucine rich repeat containing X1 (NLRX1) is an emerging therapeutic target for a spectrum of human diseases. NX-13 is a small molecule therapeutic designed to target and activate NLRX1 to induce immunometabolic changes resulting in lower inflammation and therapeutic responses in inflammatory bowel disease (IBD). This study investigates the safety of NX-13 in a seven-day, repeat-dose general toxicity study in male and female Sprague Dawley rats at oral doses of 500 and 1000 mg/kg. Weights, clinical signs, functional observational battery, clinical pathology and histopathology were used for evaluation. Daily oral dosing of NX-13 up to 1000 mg/kg did not result in any changes in weight, abnormal clinical signs or behavior. No significant differences were observed between treated and control rats in hematology or blood biochemistry. Histopathological evaluation of 12 tissues demonstrated no differences between controls and treated rats. There were no changes in weights of brain, heart, kidney, liver or spleen. Pharmacokinetic analysis of a single oral dose of NX-13 at 10 mg/kg in Sprague Dawley rats provided a maximum plasma concentration of 57 ng/mL at 0.5 h post-dose. Analysis of colon tissue after oral dosing with 1 and 10 mg/kg indicated high peak concentrations (10 and 100 µg/g, respectively) that scale in a dose-proportional manner. These experiments suggest that NX-13 is safe and well-tolerated in rats given oral doses as high as 1000 mg/kg with a favorable gastrointestinal localized pharmacokinetic profile, confirming NX-13 as a promising therapeutic for Crohn's disease and ulcerative colitis.
Activation of NLRX1 by NX-13 Alleviates Inflammatory Bowel Disease through Immunometabolic Mechanisms in CD4+ T Cells
J Immunol 2019 Dec 15;203(12):3407-3415.PMID:31694910DOI:10.4049/jimmunol.1900364.
Inflammatory bowel disease (IBD) is a complex autoimmune disease with dysfunction in pattern-recognition responses, including within the NLR family. Nucleotide-binding oligomerization domain, leucine rich repeat containing X1 (NLRX1) is a unique NLR with regulatory and anti-inflammatory functions resulting in protection from IBD in mouse models. NX-13 is an orally active, gut-restricted novel drug candidate that selectively targets and activates the NLRX1 pathway locally in the gut. In vitro and in vivo efficacy of NLRX1 activation by NX-13 was examined. Oral treatment with NX-13 alleviates disease severity, colonic leukocytic infiltration, and cytokine markers of inflammation in three mouse models of IBD (dextran sulfate sodium, Mdr1a-/-, and CD45RBhi adoptive transfer). Treatment of naive CD4+ T cells with NX-13 in vitro decreases differentiation into Th1 and Th17 subsets with increased oxidative phosphorylation and decreased NF-κB activation and reactive oxygen species. With stimulation by PMA/ionomycin, TNF-α, or H2O2, PBMCs from ulcerative colitis patients treated with NX-13 had decreased NF-κB activity, TNF-α+ and IFN-γ+ CD4+ T cells and overall production of IL-6, MCP1, and IL-8. NX-13 activates NLRX1 to mediate a resistance to both inflammatory signaling and oxidative stress in mouse models and human primary cells from ulcerative colitis patients with effects on NF-κB activity and oxidative phosphorylation. NX-13 is a promising oral, gut-restricted NLRX1 agonist for treating IBD.
