Gedunin, a natural limonoid from Meliaceae species, has been previously described as an antiinflammatory compound in experimental models of allergic inflammation. Here, we report the antiinflammatory and antinociceptive effects of gedunin in an acute model of articular inflammation induced by
Activation of toll-like receptors (TLRs) by pathogen-associated molecular patterns (PAMPs) triggers an innate immune response, via cytokine production and inflammasome activation. Herein, we have investigated the modulatory effect of the natural limonoid gedunin on TLR activation in vitro and in
Recognition of bacterial lipopolysaccharide (LPS) by innate immune system is mediated by the cluster of differentiation 14/Toll-like receptor 4/myeloid differentiation protein 2 (MD-2) complex. In this study, we investigated the modulatory effect of gedunin, a limonoid from species of the Meliaceae
Gedunin is an important limonoid present in several genera of the Meliaceae family, mainly in seeds. Several biological activities have been attributed to gedunin, including antibacterial, insecticidal, antimalarial, antiallergic, anti-inflammatory, anticancer, and neuroprotective effects. The
Alzheimer's disease (AD) is a neurodegenerative disorder and the leading cause of dementia in aged populations worldwide. The deposition of toxic protein aggregates such as amyloid beta (Aβ) is a hallmark of AD, and there is growing awareness that a key driver of AD pathogenesis is the
Seventy-three limonoids isolated from three Meliaceae plants, Azadirachta indica, A. indica var. siamensis, and Melia azedarach, or semi-synthesized from the Meliaceae limonoids, were evaluated for their inhibitory activity against nitric oxide (NO) production in mouse macrophage RAW 264.7 cells
Oleum azadirachti consists of the oil obtained from dried seeds of Azadirachta indica A. Juss. (family: Meliaceae). Local names of Azadirachta indica A. Juss. are Abodua, aforo-oyinbo, anwe egyane, arista, azad dirakht, azadarakht, azedarach and bead tree. Indigenous to India, and widely distributed
Carapa guianensis Aublet (Meliaceae), also known as andiroba, is used in popular medicine in Brazil and other countries encompassing the Amazon rainforest. Virtually all parts of the andiroba tree are utilized, including the seed's oil, which is employed to treat inflammation and infections. The
A new andirobin, thaimoluccensin A (1), and two new phragmalin-type limonoids, thaimoluccensins B (2) and C (3), were isolated from seeds of a Thai mangrove plant, Xylocarpus moluccensis, together with eight known compounds. The structures of these compounds were elucidated on the basis of
Neem (Azadirachta indica A. Juss) is one of the most versatile medicinal plants, widely distributed in the Indian subcontinent. Neem is a rich source of limonoids that are endowed with potent medicinal properties predominantly antioxidant, anti-inflammatory, and anticancer activities. Azadirachtin,
In this study, limonoids isolated from Xylocarpus plants were tested for their in vitro anti-inflammatory effects. The results demonstrated that only 7-deacetylgedunin (1), a gedunin-type limonoid, significantly inhibited lipopolysaccharide- and interferon-γ-stimulated production of nitric oxide in
Azadirachta indica, commonly known as neem, is an evergreen tree of the tropics and sub-tropics native to the Indian subcontinent with demonstrated ethnomedicinal value and importance in agriculture as well as in the pharmaceutical industry. This ancient medicinal tree, often called the
Epithelial-to-mesenchymal transition (EMT) is a self-regulated physiological process required for tissue repair that, in non-controled conditions may lead to fibrosis, angiogenesis, loss of normal organ function or cancer. Although several molecular pathways involved in EMT regulation have been
