Diarylheptanoids belong to polyphenols, a group of plant secondary metabolites with multiple biological properties. Many of them display antioxidative, cytotoxic, or anticancer actions and are increasingly recognized as potential therapeutic agents. The aim of this study was to evaluate antioxidant

The antimicrobial properties of some traditional Carrier herbal preparations were evaluated using an agar dilution method. Pitch preparations were screened against known human pathogens: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Aspergillus fumigatus. The

Oregonin, a diarylheptanoid derivative from Alnus hirsuta Turcz, Betulaceae, was evaluated for its antitumor activity. Oregonin, known to have an antitumor function, and is a novel immunomodulator, which may augment macrophage activity. MTT assays and NO production tests were performed in order to

JNK and p38 are important mitogen-activated protein kinases (MAPKs) that respond to stress stimuli. The stress-activated MAPKs associated with apoptotic cell death play vital roles in mammalian cells. Alnus hirsuta, which contains abundant diarylheptanoids derivatives, is a valuable medicinal

Forty-eight extracts from 16 common Belgian trees from the Walloon Region forest were evaluated for in vitro growth inhibitory activity against the human LoVo colon cancer, PC3 prostate cancer, and U373 glioblastoma cell lines. Our study was performed with the aim of selecting plant candidates in

Alnus nitida is used for multiple disorders in norther areas of Pakistan. In this study we have evaluated methanol extract of leaf (ANL) and stem bark (ANB) of A. nitida against two lung cancer cell lines; A-549 and H460 (Human non-small lung cancer cell lines) during in vitro assays for growth

The leaves of the Japanese Alnus sieboldiana have been extracted with n-hexane and then with methanol. A bioactivity-guided approach based on MTT assay for growth inhibition and quantitative real-time PCR for TNF-α inhibitory activity was taken to identify the active compounds in EtOAc soluble

The diarylheptanoid, oregonin (ORE), which was isolated from the bark of Alnus japonica Steudel that grows natively in Korea, has been known to exert antioxidative, anti-inflammatory, anti-cancer and immune response inhibitory effects. The antioxidative effect of ORE was observed on the superoxide

BACKGROUND The low efficacy of cancer therapy for the treatment of patients with advanced disease makes the development of new anticancer agents necessary. Because natural products are a significant source of anticancer drugs, it is important to explore cytotoxic activity of novel compounds from

Diarylheptanoids represent a group of plant secondary metabolites that possess multiple biological properties and are increasingly recognized for their therapeutic potential. A comparative study was performed on structurally analogous diarylheptanoids isolated from the bark of green (Alnus viridis)

We investigated the antitumor activity of oregonin, a diarylheptanoid derivative purified from Alnus hirsuta Turcz, Betulaceae. Oregonin is a potential novel immunomodulator, which augments the activation of natural killer (NK) cells, and thereby leads to a powerful antitumor activity. To evaluate

Relationship between autophagy and endoplasmic reticulum (ER) stress and their application to treat cancer have been actively studied these days. Recently, a lignan [(-)-(2R, 3R)-1,4-O-diferuloylsecoisolariciresinol, DFS] from Alnus japonica has been found to reduce the viability of colon cancer

Although specific compounds found in some East Asian traditional medicines have been shown to exhibit bioactive properties, their molecular mechanisms of action remain elusive. The bark of the Alnus species has been used for the treatment of various pathological conditions including hemorrhage,

An extended study of minor diarylheptanoids from the bark of black alder has resulted in the isolation of twenty diarylheptanoids, ten of which have not previously been reported (14-18, 20-24). The structures and configurations of all compounds were elucidated by NMR, HRESIMS, UV, IR, and CD. The
