gomisin a/schisandra

Following an initial cleaning-up step on the D101 macroporous resin, a preparative high-speed counter-current chromatography (HSCCC) with a two-phase solvent system composed of n-hexane-ethyl acetate-methanol-water (1:0.9:0.9:1, v/v) was used to isolate and separate schizandrin and gomisin A from

Gomisin A (GA) is a small molecular weight lignan present in Schisandra chinensis, and has been demonstrated to have vasodilatory activity. In the present study, we investigated the effect of GA on blood pressure (BP) in angiotensin II (Ang II)-induced hypertensive mice. C57/BL6 mice infused

The aim of the present study was to investigate the protective effects of gomisin A, a lignan compound isolated from Schisandra chinensis, against liver and kidney damage induced by CCl(4) exposure. We assessed alterations in organ weights, levels of serum biochemical indicators, and activation of

Gomisin A, isolated from the fruits of Schisandra chinensis, is one of the dibenzocyclooctadiene lignans. Application of 12-O-tetradecanoylphorbol-13-acetate (TPA, 1 microgram/ear), a tumor-promoting agent, to the ears of mice induces inflammation. Among seven dibenzocyclooctadiene lignans assayed,

Transient receptor potential (TRP) channel has critical actions as conditional sensors in primary afferent neurons. We studied the regulatory action of gomisin A on TRPV1 channel current in this report. Schisandra chinensis contains bioactive compounds such as the gomisin derivatives and their

Gomisin A (GA) is an active ingredient of the fruits of Schisandra chinensis which has been widely used as a tonic in traditional Korean medicine. GA induces not only endothelium-dependent but also endothelium-independent relaxation in an isolated rat's thoracic aorta. This study was aimed to

Schisandra chinensis (SC), a member of the Magnoliaceae family, has been used to improve the vascular health for postmenopausal women in Korea. In order to provide some scientific rationales for such effectiveness, this study investigated the vascular effects of gomisin A (GA) from SC. In the

OBJECTIVE Gomisin A (GA) is a small molecular weight lignan contained in Fructus Schisandrae, the dried seed of Schisandra chinensis which is widely used as a tonic in traditional Korean medicine. We previously demonstrated that GA induces endothelium-dependent and -independent relaxation in rat

OBJECTIVE This study evaluated the effects and molecular mechanisms of the Schisandra chinensis fruit extract (SC) and its major compound gomisin A (GA), on the contractility of rabbit penile corpus cavernosum smooth muscle (PCCSM). METHODS PCCSM was exposed to SC or GA after appropriate

Gomisin A (G.A) is a dietary lignan compound from Schisandra chinensis. In this study, the effect of G.A on the proliferation and metastasis of colorectal cancer (CRC) cells was investigated using several CRC cell lines and a lung metastasis mouse model. Both oral and intraperitoneal administration

Gomisin A from the fruit of Schisandra chinensis has many pharmacological properties, including hepato-protective, anti-diabetic, and anti-oxidative stress. However, the potential benefit of gomisin A is still not well understood, especially in aging progression. Therefore, the aim of this study was

Through an extensive herbal drug screening program, we found that gomisin A, a dibenzocyclooctadiene compound isolated from Schisandra chinensis, reversed multidrug resistance (MDR) in Pgp-overexpressing HepG2-DR cells. Gomisin A was relatively non-toxic but without altering Pgp expression, it

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

Gomisin A, a dibenzocyclooctadiene lignan isolated from the fruit of Schisandra chinensis, has been reported as an anti-cancer substance. In this study, we investigated the effects of gomisin A on cancer cell proliferation and cell cycle arrest in HeLa cells. Gomisin A significantly inhibited cell
