    ATB 429

    		Endogenous Metabolite Inflammation/Immunology
    ATB-429, a novel H2S-releasing derivative of mesalamine, demonstrates significant anti-nociceptive and anti-inflammatory effects in models of irritable bowel syndrome (IBS). By releasing hydrogen sulfide (H2S), ATB-429 modulates colorectal distension-induced hypersensitivity in both healthy and postcolitic rats. It attenuates abdominal withdrawal responses and suppresses spinal c-Fos mRNA expression, indicating its potential to alleviate pain associated with gastrointestinal inflammation. Moreover, ATB-429 down-regulates colonic cyclooxygenase-2 and interleukin-1β mRNA expression, effects not observed with mesalamine alone. The mechanism involves ATP-sensitive K+ (KATP) channels, as evidenced by reversal of ATB-429's effects with glibenclamide. These findings suggest ATB-429 could offer therapeutic benefits for managing painful intestinal disorders linked to inflammation .

    Ophiopogonin D

    		PPAR NF-κB Calcium Channel Reactive Oxygen Species (ROS) ERK Cardiovascular Disease Metabolic Disease Inflammation/Immunology
    Ophiopogonin D can be isolated from the tubers of Ophiopogon japonicus, is a rare naturally occurring C29 steroidal glycoside. Ophiopogonin D is a CYP2J3 inducer that significantly inhibits Ang II induced NF-κB nuclear translocation, IκBα down-regulation, intracellular Ca 2+ overload and activation of pro-inflammatory cytokines by increasing the expression of CYP2J2/EETs and PPARα in human umbilical vein endothelial cells (HUVECs). Ophiopogonin D can inhibit isteoclastic differentiation in RAW264.7 cells. Ophiopogonin D has protective effect as an antioxidant in H2O2-induced endothelial injury. Ophiopogonin D blocks ERK signaling cascades. Ophiopogonin D alleviates high-fat diet-induced metabolic syndrome and changes the structure of gut microbiota in mice. Ophiopogonin D has been used against inflammatory, metabolic and cardiovascular diseases .

Aβ42 oligomers bind to various neuronal surface receptors (such as PrPc, mGluR5, NMDA receptors, etc.), triggering oxidative stress, calcium homeostasis imbalance, and synaptic toxicity via activating downstream signaling pathways, leading to neuronal dysfunction and death .
