Suppression of ZEB1 by Ethyl caffeate attenuates renal fibrosis via switching glycolytic reprogramming.

Renal fibrosis (RF) is a common endpoint of various chronic kidney diseases, leading to functional impairment and ultimately progressing to end-stage renal failure. Glycolytic reprogramming plays a critical role in the pathogenesis of fibrosis, which maybe a potential therapeutic target for treating renal fibrosis. Here, we revealed the novel role of ZEB1 in renal fibrosis, and whether targeting ZEB1 is the underlying mechanism for the anti-fibrotic effects of ethyl caffeate (EC) to regulate the glycolytic process.

ShaShen-MaiDong decoction attenuates bleomycin-induced pulmonary fibrosis by inhibiting TGF-β/smad3, AKT/MAPK, and YAP/TAZ pathways.

Ethnopharmacological Relevance: Pulmonary fibrosis (PF) is progressive and terminal lung disease, which is also the most common sequelae of Corona Virus Disease (2019) (COVID-19) survivors. Unfortunately, there is currently no cure for PF. ShaShen-MaiDong decoction (SMT), a traditional Chinese medicine, has been employed in treating various lung diseases, which may offer potential therapeutic benefits for PF.

Liver X receptor inverse agonist SR9243 attenuates rheumatoid arthritis via modulating glycolytic metabolism of macrophages.

Liver X receptors (LXRs) which link lipid metabolism and inflammation, were overexpressed in experimental rheumatoid arthritis (RA) rats as observed in our previous studies, while suppression of LXRα by silybin ameliorates arthritis and abnormal lipid metabolism. However, the role of LXRs in RA remains undefined. In this study, we investigated the inhibition role of LXRs in the polarization and activation of M1 macrophage by using a special LXRs inverse agonist SR9243, which led to ameliorating the progression of adjuvant-induced arthritis (AIA) in rats.

Novel nano-drug delivery system for natural products and their application.

The development of natural products for potential new drugs faces obstacles such as unknown mechanisms, poor solubility, and limited bioavailability, which limit the broadened applicability of natural products. Therefore, there is a need for advanced pharmaceutical formulations of active compounds or natural products. In recent years, novel nano-drug delivery systems (NDDS) for natural products, including nanosuspensions, nanoliposomes, micelle, microemulsions/self-microemulsions, nanocapsules, and solid lipid nanoparticles, have been developed to improve solubility, bioavailability, and tissue distribution as well as for prolonged retention and enhanced permeation.

Targeting abnormal lipid metabolism of T cells for systemic lupus erythematosus treatment.

Systemic lupus erythematosus (SLE) is an autoimmune disease in which the immune system attacks its own tissues and organs. However, the causes of SLE remain unknown. Dyslipidemia is a common symptom observed in SLE patients and animal models and is closely correlated to disease activity.

Sinomenine ameliorates collagen-induced arthritis in mice by targeting GBP5 and regulating the P2X7 receptor to suppress NLRP3-related signaling pathways.

Sinomenine (SIN) is an isoquinoline alkaloid isolated from Sinomenii Caulis, a traditional Chinese medicine used to treat rheumatoid arthritis (RA). Clinical trials have shown that SIN has comparable efficacy to methotrexate in treating patients with RA but with fewer adverse effects. In this study, we explored the anti-inflammatory effects and therapeutic targets of SIN in LPS-induced RAW264.

The Protective Effects of Hydrogen Sulfide New Donor Methyl -(4-Fluorobenzyl)--(3,4,5-Trimethoxybenzoyl)-l-Cysteinate on the Ischemic Stroke.

In this paper, we report the design, synthesis and biological evaluation of a novel -allyl-l-cysteine (SAC) and gallic acid conjugate -(4-fluorobenzyl)--(3,4,5-trimethoxybenzoyl)-l-cysteinate (MTC). We evaluate the effects on ischemia-reperfusion-induced PC12 cells, primary neurons in neonatal rats, and cerebral ischemic neuronal damage in rats, and the results showed that MTC increased SOD, CAT, GPx activity and decreased LDH release. PI3K and p-AKT protein levels were significantly increased by activating PI3K/AKT pathway.

The protective effects of hydrogen sulfide on the myocardial ischemia via regulating Bmal1.

Background: To investigate the effect of hydrogen peroxide (HS) on myocardial clock gene Bmal1 in ischemic cardiomyocytes.

Materials & Methods: Quantitative PCR (qPCR) was used to detect the expression of Bmal1 at the mRNA level in H9C2 rat cardiomyocytes. The protein expressions of Bax and Bcl-2, PI3K/Akt, caspase-3 were measured by western blotting.

Design, synthesis and biological evaluation of novel chromeno[4,3-c]pyrazol-4(2H)-one derivates containing sulfonamido as potential PI3Kα inhibitors.

A series of novel chromeno[4,3-c]pyrazol-4(2H)-one derivates contained sulfonamido were designed and synthesized, and their anticancer effects in vitro was evaluated to develop some new PI3Kα inhibitors. Most of desired compounds exhibited the better antiproliferative activities against four cancer cell lines than that of LY294002. Out of them, compound 4o displayed the potent antiproliferative activity and high selectivity against the PI3Kα protein and it can induce apoptosis of HCT116 in a dose-dependent manner.
