yakuchinone/inflammation

Certain medicinal plants contain anti-inflammatory and antioxidative substances that can exert chemopreventive effects. Our previous studies have demonstrated that the methanol extract of Alpinia oxyphylla Miquel (Zingiberaceae) inhibits tumor promotion in mouse skin. Two major diarylheptanoids

BACKGROUND Alpinia oxyphylla is a common remedy in traditional Chinese medicine. Yakuchinone A is a major constituent of A. oxyphylla and exhibits anti-inflammatory, antitumor, antibacterial, and gastric protective activities. METHODS Antioxidant and antitumor characteristics of yakuchinone A in

The benzylideneacetophenone derivative JC3 [(2E)-3-(4-hydroxy-3-methoxyphenyl)phenylpro-2-en-l-one] (JC3) was synthesized by modifying yakuchinone B obtained from the seeds of Alpinia oxyphylla, a member of the ginger family (Zingiberaceae), which are widely used as a folk remedy and as an

Toll-like receptor 4 (TLR4) pathway is one of the major pathways that mediate the inflammation in human body. There are different anti-inflammatory drugs available in the market which specifically act on different signaling proteins of TLR4 pathway but they do have few side effects and other

Alpinia oxphylla Miquel, which belongs to the ginger family (Zingiberaceae), has been used in Oriental herbal medicine. Our recent studies have revealed that the methanolic extract of A. oxyphylla suppresses mouse skin tumor promotion and induces apoptosis in cultured human promyelocytic leukemia

Alpinia oxyphylla is a traditional Chinese medicine widely used for treating diarrhea, ulceration, and enuresis. Moreover, A. oxyphylla is effective for cognitive function improvement and nerve regeneration. Multiple sclerosis (MS) is a chronic neuronal inflammatory autoimmune disease

Diarylheptanoids possess potent anti-inflammatory properties. However, the mechanism of their action is not fully understood. In this study, we found that three diarylheptanoids, 1-(3, 5-dimethoxy-4-hydroxyphenyl)-7-phenylhept-1-en-3-one (YPE-01), yakuchinone B and demethyl-yakuchinone B, reduced

The aim of the present study was to identify a new candidate anti-inflammatory compound for use in the active stage of thyroid-associated ophthalmopathy (TAO). Benzylideneacetophenone compound JC3 [(2E)-3-(4-hydroxy-3-methoxyphenyl)phenylpro-2-en-l-one] was synthesized based on a structural

Recently, considerable attention has been focused on identifying naturally occurring chemopreventive substances capable of inhibiting, retarding, or reversing the multi-stage carcinogenesis. A wide array of phenolic substances, particularly those present in dietary and medicinal plants, have been
