The search for new compounds effective against Mycobacterium tuberculosis is still a priority in medicine. The evaluation of microorganisms isolated from non-conventional locations offers an alternative to look for new compounds with antimicrobial activity. Endophytes have been successfully explored as source of bioactive compounds. In the present work we studied the nature and antimycobacterial activity of a compound produced by Streptomyces scabrisporus, an endophyte isolated from the medicinal plant Amphipterygium adstringens...

Amphipterygium adstringens is an endemic species in Mexico commonly known as "cuachalalate." Healers to treat gastritis, gastric ulcers, and gastrointestinal cancer have traditionally used the bark. We investigated the effects of alcoholic extract of A. adstringens (AaEE) in DSS-induced colitis in mice. The protective effect of AaEE was determined at 200 mg/kg by oral gavage for 10 days. We determine the effect of AaEE on clinical features (disease activity index), antioxidants, anti-inflammatory, and immunomodulatory activities in relation to the activity of SOD, CAT, and GPx, levels of proinflammatory cytokines, and changes both macroscopic and microscopic of the colonic mucosa...

Amphipterygium adstringens is a plant traditionally used to treat gingivitis, gastric ulcer and even gastric cancer but the mechanism involved in the regulation of the immune response is not elucidated yet. The 6-pentadecylsalicylic acid (6SA) is the main anacardic acid found in A. adstringens. In order to evaluate the immune-modulatory abilities of 6SA, we used mouse splenocytes and determined the phosphorylation of the transcription factor NF-κB and MAP kinases ERK1/2, JNK and p38 in helper and cytotoxic T cells, natural killer (NK) cells and F4/80(+) macrophages...

In Mexico, as in many other countries, traditional medicine is used for the treatment of several diseases. In particular, Amphipterygium adstringens infusion is used for gastritis, gastric ulcers, and gastric cancer. Extracts from this tree have microbicidal effects against Helicobacter pylori, an important risk factor for gastric cancer development. Anacardic acids are constituents of A. adstringens, and 6-pentadecyl salicylic acid (6-PSA) is the most abundant. However, there is a lack of information regarding the effects of 6-PSA on cancer cells...

Anacardic acid (6-pentadecylsalicylic acid, AA), a natural compound isolated from the traditional medicine Amphipterygium adstringens, has been reported to possess antitumor activities. However, its molecular targets have not been thoroughly studied. Here, we report that AA is a potent inducer of endoplasmic reticulum (ER) stress, leading to apoptosis in hepatoma HepG2 and myeloma U266 cells. Induction of ER stress by AA was supported by a dose- and time-dependent increase in expression of the ER signaling downstream molecules, such as GRP78/BiP, phosphorylated eIF2α, ATF4 and CHOP in both HepG2 and U266 cell lines...

Anacardic acid (6-pentadecylsalicylic acid), a natural inhibitor of histone acetyltransferase from Amphipterygium adstringens, has been shown to have anti-inflammatory, anticancer, antioxidative, and antimicrobial functions. However, whether this salicylic acid could block angiogenesis has not been elucidated to date. Here, we postulate that anacardic acid affects multiple steps of tumor angiogenesis to contribute to tumor inhibition. In this study, we found that vascular endothelial growth factor (VEGF)-induced cell proliferation, migration, and adhesion and capillary-like structure formation of primary cultured human umbilical vascular endothelial cells (HUVECs) could all be significantly suppressed by anacardic acid in vitro, without detectable cellular toxicity...
