Tetradecyl 2,3-Dihydroxybenzoate Improves Cognitive Function in AD Mice by Modulating Autophagy and Inflammation Through IPA and Hsc70 Targeting.

Drug development for Alzheimer's disease (AD) treatment is challenging due to its complex pathogenesis. Tetradecyl 2,3-dihydroxybenzoate (ABG-001), a leading compound identified in our prior research, has shown promising NGF-mimicking activity and anti-aging properties. In the present study, both high-fat diet (HFD)-induced AD mice and naturally aging AD mice were used to evaluate anti-AD effects.

Mixture of Peanut Skin Extract, Geniposide, and Isoquercitrin Improves the Hepatic Lipid Accumulation of Mice via Modification of Gut Microbiota Homeostasis and the TLR4 and AMPK Signaling Pathways.

Metabolic-dysfunction-associated steatotic liver disease (MASLD, formerly known as NAFLD) is a global chronic liver disease, and no licensed drugs are currently available for its treatment. The incidence of MASLD is increasing, which could lead to a huge clinical and economic burden. As a multifactorial disease, MASLD involves a complex set of metabolic changes, and many monotherapies for it are not clinically effective.

A new gentiopicroside derivative improves cognitive deficits of AD mice via activation of Wnt signaling pathway and regulation of gut microbiota homeostasis.

Background: In our previous study, we found that gentiopicroside (GPS) isolated from Gentiana rigescens Franch has a significant antiaging activity via regulation of mitophagy and oxidative stress. In order to increase the anti-aging activity of GPS, several compounds based on the chemical structure of GPS were synthesized and evaluated for bioactivity with yeast replicative lifespan assay, and 2H-gentiopicroside (2H-GPS) as leading compound was selected for AD treatment.

Purpose And Methods: To investigate whether 2H-GPS has anti- Alzheimer's disease effects, we used D-galactose (Dgal)-induced model mice to evaluate the effect of 2H-GPS on AD mice.

Isoquercitrin from L. produces an anti-obesity effect on obese mice by targeting C-1-tetrahydrofolate synthase, carbonyl reductase, and glutathione -transferase P and modification of the AMPK/SREBP-1c/FAS/CD36 signaling pathway in mice .

In the present study, mice with high-fat-diet-induced obesity were used in investigating the anti-obesity effects of an aqueous extract and isoquercitrin from L. The aqueous extract and the signal molecule isoquercitrin significantly reduced the body weight gain, food intake, water consumption, and fasting blood glucose, plasma triglyceride and total cholesterol levels of the obese mice. Furthermore, the mechanism of action of isoquercitrin was explored through RT-PCR analyses and uptake experiments of adenosine 5'-monophosphate-activated protein kinase (AMPK) and sterol regulatory-element binding protein (SREBP-1c) inhibitors and glucose.

Gastrodin From Enhances Cognitive Function and Neuroprotection of AD Mice the Regulation of Gut Microbiota Composition and Inhibition of Neuron Inflammation.

Gastrodin (Gas) is known to exhibit neuroprotective effects in Alzheimer's disease (AD). However, the detailed mechanism of action is still unclear. In the present study, we focused on the microbiome-gut-brain axis to investigate the mechanism of action of Gas using a D-galactose (Dgal)-induced AD model.

Protocatechuic acid ameliorates neurobehavioral deficits via suppression of oxidative damage, inflammation, caspase-3 and acetylcholinesterase activities in diabetic rats.

Clinical and experimental data have demonstrated that diabetes is associated with neurological complications. Protocatechuic acid (PCA) is a phenolic phytochemical widely reported to possess antidiabetic property. However, there is no scientific information on the influence of PCA on diabetes-induced neurotoxicity.

Impact of prepubertal exposure to dietary protocatechuic acid on the hypothalamic-pituitary-testicular axis in rats.

Protocatechuic acid (PCA; 3, 4-dihydroxybenzoic acid) is a phenolic compound widely found in many edible fruits, vegetables, grape wine and plant-derived beverages. The present study investigated the impact of PCA on the hypothalamic-pituitary-testicular axis of rats orally treated with PCA during the period of prepubertal development to adulthood. Protocatechuic acid was administered to prepubertal male rats at doses of 0, 5, 10, 50 and 100 mg/kg body for 45 consecutive days.
