15 phenolic amides (PAs) have been synthesized and examinedin vitrousing four tests: (1) prevention of Cu2+-induced human low-density lipoprotein oxidation, (2) scavenging of stable radicals, (3) anti-inflammatory activity, and (4) scavenging of superoxide radicals.

Cholestin shows a protective effect against hepatotoxicity indices in ethanol-fed rats comparable to that of silymarin, as supported by the evaluation of liver histopathology. The data suggest that Cholestin exerts its hepatoprotective effect by decreasing lipid peroxidation and improving antioxidants status, thus proving itself as an effective antioxidant in ethanol-induced oxidative damage in rats.

A study was undertaken to investigate the dietary effect of taurine in chronic alcoholic patients. The 30 chronic alcoholic patients with 2 to 5 times greater than normal activities of aspartate transaminase (AST) or alanine transaminase (ALT) were selected and equally divided into taurine and control groups. In the taurine group, each patient took 6 g taurine per day, divided into 3 doses, for three months, and then stopped treatment for 1 month. In the control group, patients took a placebo without taurine for 4 months. It was found that the AST and ALT activities and levels of cholesterol, triglyceride (TG), bilirubin, and thiobarbituric acid reactive substances (TBARS) of serum plasma in the taurine group were all decreased, but increased alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activities and serum vitamins concentrations. Except for the level of TG, all were significantly different after taking taurine for 2 or 3 months. It indicated that taurine plays an important role in the properties of antioxidation and has some improvement on the liver tests of chronic alcoholic patients.

To investigate a high cholesterol diet in Alzheimer’s disease (AD) mice, they were fed with (2% cholesterol) in five groups with a control group, AD mice group, AD mice plus Meretrix lusoria group, AD mice plus Geloina eros group, and, AD mice plus Corbicula fluminea group for three months, and treated with the fatty acid profiles of clams by gas chromatography (GC). The results showed that treatment with clams for three months reduced Fas/L and Caspase-3 in the Meretrix lusoria and Geloina eros groups, but Fas-associated death domain (FADD) and Caspase-8 were strongly reduced in the Geloina eros group. For the mitochondria-dependent apoptotic pathway, the reduction of apoptosis proteins were observed in the hearts of clams-treated AD mice. BAK and Caspase-9 was reduced in the Meretrix lusoria group, but Caspase-3 and Cytochrome-c were reduced in Geloina eros group. Enhancement of survival proteins p-AKT, p-IGF1R, p-PI3K, Bcl-XL, Bcl2, and the longevity SIRT1 signaling proteins, p-AMPK-α, SIRT1, PGC1-α, p-FOXO3 were observed in clams-treated mice and even more strongly enhanced in the Meretrix lusoria, Geloina eros and Corbicula fluminea groups. This study observed that the ingestion of clams caused a reduction of apoptosis proteins and enhancement of survival and SIRT1 signaling proteins in the hearts.
