- |||||||||| Preclinical, Journal: Liquiritin Alleviates Depression-Like Behavior in CUMS Mice by Inhibiting Oxidative Stress and NLRP3 Inflammasome in Hippocampus. (Pubmed Central) - Jan 26, 2022
However, liquiritin did not alter the thermal stability of NLRP3 in the cellular thermal shift assay (CETSA), suggesting that its inhibition of NLPR3 was not by direct targeting of NLRP3 protein. Liquiritin attenuates depression-like behavior of CUMS mice and inhibited cytokines levels triggered by NLRP3 inflammasome, suggesting the antidepressant action is, at least partially, associated with antioxidant stress and inhibition of NLRP3 inflammasome activation.

- |||||||||| Journal, IO biomarker: NLRP3 Inflammasome Inhibitor BAY-117082 Reduces Oral Squamous Cell Carcinoma Progression. (Pubmed Central) - Jan 20, 2022
Furthermore, the in vivo study demonstrated that BAY-117082 at doses of 2.5 and 5 mg/kg significantly decreased subcutaneous tumor mass, and also reduced NLRP3 inflammasome pathway activation. Therefore, based on these results, the use of BAY-117082 could be considered a promising strategy to counteract oral cancer progression, thanks its ability to modulate the NLRP3 inflammasome and apoptosis pathways.

Journal: Luxeptinib Disables NLRP3 Inflammasome-Mediated IL-1β release and Pathways Required for Secretion of Inflammatory Cytokines IL-6 and TNFα. (Pubmed Central) - Jan 20, 2022 It also inhibits the kinases p38MAPK, ERK1/2, SAPK/JNK and activation of transcription factor NF-κBp65 with a concentration profile similar to its inhibition of cytokine release. Implications: The ability of luxeptinib to inhibit the NLRP3-mediated release of IL-1β and pathways involved in the release of IL-6 and TNFα at concentrations which are well-tolerated in patients makes it a candidate for the treatment of inflammatory diseases and inflammation-associated resistance in cancer.
- |||||||||| Journal: Discovery of novel triazole compounds as selective IL-1β releasement inhibitors. (Pubmed Central) - Jan 19, 2022
In 20 μM, compound 19 exhibited IL-1β releasement inhibitory activity (IC =5.489 μM) which closed to the original compound, and 4.5-fold superior selectivity (SI =4.71) to the lead compound (SI = 0.82). A probable SAR model of triazole derivatives for IL-1β releasement inhibition and selectivity was also proposed, which might promote the discovery of more effective and specific IL-1β releasement inhibitors in the future.
- |||||||||| rosuvastatin / Generic mfg.
Journal, IO biomarker: Rosuvastatin corrects oxidative stress and inflammation induced by LPS to attenuate cardiac injury by inhibiting the NLRP3/TLR4 pathway. (Pubmed Central) - Jan 18, 2022 Administration of rosuvastatin reduced the increases in expression of NLRP3, ASC, pro-caspase-1, TLR4, and p65 and decreased the contents of TNF-α, IL-1β, IL-18 and IL-6, with a similar effect as MCC950 (NLRP3 inhibitor). In conclusion, inhibition of the inflammatory response and oxidative stress contributes to cardioprotection of rosuvastatin on cardiac injury induced by LPS, and the effect of rosuvastatin was achieved by inactivation of the NF-κB/NLRP3 pathway.
- |||||||||| Preclinical, Journal: NLRP3 inflammasome inhibitor cucurbitacin B suppresses gout arthritis in mice. (Pubmed Central) - Jan 18, 2022
Consistent with this, CuB pretreatment also ameliorated MSU-induced arthritis in vivo models of gout arthritis, manifested by reduced foot swelling and inflammatory cell infiltration. Taken together, our data provide the evidence that CuB is a NLRP3 inflammasome inhibitor with therapeutic potential for treating NLRP3 inflammasome-mediated diseases, especially gouty arthritis.
- |||||||||| Preclinical, Journal: Exercise Inhibits NLRP3 Inflammasome Activation in Obese Mice via the Anti-Inflammatory Effect of Meteorin-like. (Pubmed Central) - Jan 18, 2022
Exercise significantly enhanced the expression of METRNL in various muscle depots, and further in vitro analysis revealed that recombinant METRNL treatment inhibited IL-1β secretion in macrophages. In conclusion, exercise exerts its anti-inflammatory action by suppressing adipose tissue NLRP3 inflammasome, and this is, in part, associated with METRNL induction in muscle and its anti-inflammatory effects in macrophages.

Of translational significance, adeno-associated virus-mediated overexpression of Kindlin-2 inhibits ECM catabolism and cell apoptosis in primary human NP cells in vitro and alleviates coccygeal IVDD progression caused by mechanical stress in rat. Collectively, we establish critical roles of Kindlin-2 in inhibiting Nlrp3 inflammasome activation and maintaining integrity of the IVD homeostasis and define a novel target for the prevention and treatment of IVDD.

Collectively, we establish critical roles of Kindlin-2 in inhibiting Nlrp3 inflammasome activation and maintaining integrity of the IVD homeostasis and define a novel target for the prevention and treatment of IVDD. These results reveal that MCC950 exerts neuroprotective effects by reducing neuronal apoptosis, preserving the survival of the remaining neurons, attenuating the severity of the damage, and promoting the recovery of motor function after SCI.

Methyl gallate was also active ex vivo against ATP-treated PBMCs and synovial fluid mononuclear cells from patients with gout. In conclusion, methyl gallate has a nephroprotective effect against PO-induced HN through blocking the oligomerization of NLRP3 and then exerting anti-inflammatory activity in the NLRP3-driven diseases.
- |||||||||| Preclinical, Journal, IO biomarker: Shugan Hewei Decoction Alleviates Cecum Mucosal Injury and Improves Depressive- and Anxiety-Like Behaviors in Chronic Stress Model Rats by Regulating Cecal Microbiota and Inhibiting NLRP3 Inflammasome. (Pubmed Central) - Jan 7, 2022
SHD regulated the excessive expression of NLRP3, ASC, caspase-1, interleukin-1β (IL-1β), and IL-18 in the serum and cecum mucosa induced by CUS, as well as the activation of the Toll-like receptor 4/nuclear factor-κB signaling cascades. Our results reveal the pharmacological mechanisms of SHD and provide a validated therapeutic method for the treatment of depression, anxiety, and cecum mucosal injury.
- |||||||||| Journal: The E3 Ubiquitin Ligase TRIM65 Negatively Regulates Inflammasome Activation Through Promoting Ubiquitination of NLRP3. (Pubmed Central) - Jan 6, 2022
TRIM65-deficient mice had a higher production of IL-1β induced by lipopolysaccharide in sera, and more IL-1β secretion and neutrophil migration in the ascites, and more severity of joint swelling and associated IL-1β production induced by monosodium urate, suggesting that TRIM65 deficiency was susceptible to inflammation. Therefore, the data elucidate a TRIM65-dependent negative regulation mechanism of NLRP3 inflammasome activation and provide potential therapeutic strategies for the treatment of NLRP3 inflammasome-related diseases.
