6-Hydroxyhexanoic acid
Based on 1 publication(s) in Google Scholar
6-Hydroxyhexanoic acid (6-HHA) is a bacterial effector molecule with metabolic and immunomodulatory activities. 6-Hydroxyhexanoic acid activates the JAK1-STAT1 signaling pathway, promotes phenotypic conversion of M2 macrophages to M1 macrophages, and exerts anti-tumor effects by regulating macrophage polarization. 6-Hydroxyhexanoic acid inhibits lipolysis in adipocytes mediated by Gαi family GPCR, and reduces high-fat diet-induced weight gain and obesity. 6-Hydroxyhexanoic acid can be used in studies related to pancreatic ductal adenocarcinoma, obesity, and insulin resistance.

Biological Activity
6-Hydroxyhexanoic acid (50-1000 ng/mL; 48 h) induces M1 polarization of mouse bone marrow-derived macrophages (BMDMs) in a concentration-dependent manner[1].
6-Hydroxyhexanoic acid (200 ng/mL; 24 h) repolarizes human THP-1-derived M2 macrophages to the M1 phenotype, which is characterized by increased iNOS expression and decreased CD206 expression[1].
6-Hydroxyhexanoic acid (200 ng/mL; 24 h) induces M1 polarization of mouse BMDM-derived M2 macrophages via the JAK1-STAT1 signaling pathway; pre-treatment with 20 μg/mL IFNAR1 antibody for 48 h attenuates 6-HHA-mediated upregulation of iNOS expression and increase in the proportion of M1 macrophages, but does not affect the downregulation of Arg1 expression[1].
6-Hydroxyhexanoic acid (200 ng/mL; 24 h) repolarizes M2 macrophages differentiated from mouse bone marrow-derived macrophages (BMDM) to the M1 phenotype, which is characterized by upregulated CD86 expression, downregulated CD206 expression, and increased secretion levels of TNF-α and IL-12[1].
6-Hydroxyhexanoic acid (200 ng/mL; 24 h) induces transcriptome remodeling in mouse BMDM-derived M2 macrophages, leading to their conversion to the proinflammatory M1 phenotype, while significantly activating the JAK-STAT signaling pathway and upregulating M1-related genes[1].
6-Hydroxyhexanoic acid (200 ng/mL; 48 h) combined with medium from mouse bone marrow-derived macrophages (BMDMs) inhibits the proliferation, migration and colony-forming ability of mouse Panc02 pancreatic adenocarcinoma cells[1].
6-Hydroxyhexanoic acid (0.1 mM; 24 h) significantly inhibits TNF-α-induced IL-6 secretion in differentiated 3T3-L1 adipocytes, with no effect on basal cytokine production[2].
6-Hydroxyhexanoic acid (0.1 mM; 24 h) significantly inhibits isoproterenol-induced FFA release in differentiated 3T3-L1 adipocytes, and this effect depends on the Gαi-mediated signaling pathway[2].
6-Hydroxyhexanoic acid (0.1 mM) inhibits the production of proinflammatory cytokines in human gingival fibroblasts[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
6-Hydroxyhexanoic acid (200 ng/mL; intraperitoneal injection; every 3 days; 3 weeks, co-administered with 250 μg/mouse IFNAR1 inhibitor) relies on the JAK1-STAT1 signaling pathway for induced tumor-associated macrophage M1 polarization and subsequent antitumor activity in orthotopic pancreatic ductal adenocarcinoma mouse models[1].
6-Hydroxyhexanoic acid (1.1-2.2 mg/kg; i.p.; every other day; 3 weeks) improves adiposity, insulin sensitivity, and systemic and adipose tissue inflammation in diet-induced obese mice, with significant effects observed at the 2.2 mg/kg dose[2].
