IL-1 Modulator

APH003 is an orally active IRAK4 PROTAC degrader with a DC₅₀ of 0.74 nM in human peripheral blood mononuclear cells (hPBMCs). APH003 recruits IRAK4 to CRBN to form a ternary complex, mediates the ubiquitination and degradation of IRAK4 via the ubiquitin-proteasome pathway, and inhibits the kinase activity of IRAK4. APH003 inhibits LPS- or IL-1β/LPS-induced phosphorylation of ERK, JNK and NF-κB. APH003 inhibits the secretion of TNF-α, IL-6, IL-8 and IL-13 by stimulated hPBMCs. APH003 exhibits anti-inflammatory activity in rat TNBS-induced intestinal inflammation models and mouse IL-33-induced skin inflammation models. APH003 can be used in research related to inflammatory bowel disease and skin inflammation.

Antiflammin-1 is an anti-inflammatory peptide 1 (MQMKKVLDS). Antiflammin-1 is a derivative of uteroglobin. Antiflammin-1 has anti-inflammatory and antifibrotic actions in bleomycin (HY-108345)-induced lung injury.

2-ARA-LysoPtdEtn (1-Lyso-2-arachidonoyl-sn-glycero-3-phosphoethanolamine) is an orally active polyunsaturated acyl lysophosphatidylethanolamine. 2-ARA-LysoPtdEtn diminishes formation of LTC₄, LTB₄, and 12-HETE. 2-ARA-LysoPtdEtn lowers levels of IL-1β, IL-6, TNF-α, and NO. 2-ARA-LysoPtdEtn augments IL-10 levels and upgrades formation of 15-HETE and LXA₄. 2-ARA-LysoPtdEtn can be used for the research of peritonitis.

Lemairamin (Wgx-50) is a hydroxylamine compound. Lemairamin can be isolated from the pericarps of the Zanthoxylum plants. Lemairamin activates α7nAChR, stimulates the expression of IL-10 and POMC. Lemairamin shows a decrease in Akt. Lemairamin attenuates DSS-induced intestinal inflammation. Lemairamin alleviates pain hypersensitivity.

13 (S)-HOTrE is an oxylipin metabolite of α-Linolenic acid (HY-N0728). 13 (S)-HOTrE mediates the inactivation of the NLRP3 inflammasome through the PPAR-γ pathway to exert anti-inflammatory effects. 13 (S)-HOTrE inhibits NF-κB nuclear translocation, ROS production, autophagy and IL-1β levels, induces apoptosis, and increases IL-10 levels. 13 (S)-HOTrE alleviates LPS-induced inflammatory responses in macrophages, prolongs the survival time of septic mice, and regulates the immunometabolic phenotype in parenteral nutrition mouse models. 13 (S)-HOTrE can be used in the research of immune and inflammation-related diseases.

Pseudoginsenoside RT4 is an orally active anti-inflammatory agent. Pseudoginsenoside RT4 can be isolated from Panax pseudoginseng subsp. Himalaicus, Panax vietnamensis Ha et Grushv, and Panax quinquefolius L. Pseudoginsenoside RT4 reduces the levels of TNF-α, IL-6, and IL-1β, elevates the level of IL-10, improves the histopathological features of colon tissue, maintains the ultrastructure of colonic epithelium, protects the integrity of cell monolayers, increases the expression of tight junction proteins, raises the total content of short-chain fatty acids, corrects intestinal flora disorder, reduces the disease activity index score, restores colon length, and decreases the spleen index. Pseudoginsenoside RT4 exhibits hepatoprotective effects. Pseudoginsenoside RT4 can be used in studies related to ulcerative colitis.

Chitohexaose hexahydrochloride is a small molecular polysaccharide. Chitohexaose hexahydrochloride inhibits the binding of AgW to TLR4. Chitohexaose hexahydrochloride upregulates IL-10, inhibits LPS-induced upregulation of ROS, induces alternative activation of macrophages/monocytes, and suppresses LPS-induced production of TNF-α, IL-1β and IL-6. Chitohexaose hexahydrochloride reverses the mortality of mice challenged with APAP or LPS. Chitohexaose hexahydrochloride can be used in research related to Acetaminophen (HY-66005)-induced hepatotoxicity and endotoxemia.
