DCVC inhibits pathogen-stimulated TNF-α in human extra placental membranes in vitro.Target: TNF-αin vitro: DCVC inhibits pathogen stimulated cytokine release from tissue punch cultures. DCVC (5-50 μM) significantly inhibits LTA-, LPS-, and GBS-stimulated cytokine release from tissue cultures as early as 4 h (P ≤ 0.05). In contrast, TCA (up to 500 μM) does not inhibit LTA-stimulated cytokine release from tissue punches. DCVC effects on LTA-stimulated and LPS-stimulated TNF-α release from tissue punch cultures of extraplacental membranes. DCVC effects on GBS-stimulated release of pro-inflammatory cytokines from extraplacental membranes in transwell cultures. [1]. Boldenow E, et al.

Lentztrehalose B, a microbial disaccharide metabolite isolated from Lentzea, exhibits a range of biological activities. At a concentration of 100 µM, it demonstrates antioxidant properties in an oxygen radical absorbance capacity (ORAC) assay. Furthermore, Lentztrehalose B at 10 mM inhibits porcine kidney trehalase, an enzyme involved in trehalose metabolism. Additionally, it induces autophagy in MeWo melanoma and OVK18 ovarian cancer cells when applied at 100 mM.

Lentztrehalose A, a disaccharide microbial metabolite identified in Lentzea, exhibits a range of biological activities. This compound specifically inhibits M. smegmatis trehalase—an enzyme involved in trehalose metabolism—more effectively than trehalase from porcine kidney, with IC50 values of 0.67 mM and >20 mM, respectively. Additionally, Lentztrehalose A at a concentration of 100 mM promotes autophagy in MeWo melanoma and OVK18 ovarian cancer cells. When administered at 50 mg kg daily, it enhances survival rates and impedes tumor growth in a Sarcoma 180 murine sarcoma model.

Potassium 1H-indol-3-yl sulfate (Potassium 3-indoxyl sulfate) 是人芳烃受体(AhR)的激动剂。芳烃受体(AhR)最近被发现是免疫炎症条件的病理生理调节剂，Potassium 1H-indol-3-yl sulfate 已被证明是AhR的配体。Potassium 1H-indol-3-yl sulfate 也是膳食蛋白质中色氨酸的代谢物。色氨酸被肠道细菌代谢为吲哚，吲哚被吸收到血液中，然后在肝脏中进一步代谢为硫酸吲哚，通常通过尿液排出体外。在肾功能受损的慢性肾病患者中，Potassium 1H-indol-3-yl sulfate 可作为尿毒症毒素在血清中积累，诱导氧化应激并加速疾病进展。250 μM Potassium 1H-indol-3-yl sulfate 可诱导NF-Κb活化，促进大鼠近端小管细胞TGF-β1和Smad3的表达，与促纤维化活性相关。

Phenyl sulfate为肠道微生物衍生的口服活性代谢物，能在糖尿病实验模型中诱发蛋白尿及足细胞损伤，其可能成为糖尿病肾病的疾病标志物和未来治疗靶点。
