The purposes of this study were to identify physicochemical properties and evaluate bioactive compound levels and antioxidant characteristics at 30 day intervals during the 90 days of fermentation of fortified with five different varieties of red pepper: Juktoma pepper (RP1), facing heaven pepper (RP2), Thai chili pepper (RP3), bird's eye pepper (RP4), and red bell pepper (RP5). Physicochemicals properties, including reducing sugar, capsaicin, pH, β-carotene, and color parameters, of were evaluated. Antioxidant compounds of total polyphenols and total flavonoids were analyzed with antioxidant activities of DPPH and FRAP assays.

Gomisin A (GA), a lignan component contained in the fruit of Schisandra chinensis Baillon, improves hepatic cell degeneration, vasodilatory activity and insulin sensitivity. These effects also impact the immune system, including various inflammatory mediators and cytokines. In this study, the anti-inflammatory effect of GA on lipopolysaccharide-stimulated mouse peritoneal macrophages was studied.

In a previous study, we found that the 3,4-dihydroquinazoline derivative, 4-(Benzylcarbamoylmethyl)-2-(biphenyl-4-ylamino)-3-(5-tert-butyloxycarbamoyl-1-pentyl)-3,4-dihydroquinazoline (KYS05047), was a selective T-type Ca(2+) channel blocker with anti-proliferative effects against various cancer cells. However, the mechanism responsible for its effects has not been studied. In this study, we investigated the effect of KYS05047 on cell cycle arrest and the mechanisms involved in human lung adenocarcinoma A549 cells.
