  • Oligomeric flavanoids. Part 13. Synthesis of profisetinidins based on (−) robinetinidol and (+) -epifisetinidol
    作者:Johannes C.S. Malan、Jacobus A. Steenkamp、Desmond A. Young、Daneel Ferreira

    (−)-robinetinidol[(2R,3S)-2,3-trans-flavan-3,3′,4′,5′,7-pentaol] afforded a novel series of bi-, tri-, and tetraflavanoid profisetinidins. They are accompanied by (−)-fisetinidol-(4α,2′)-(−)-robinetinidol which results from the pyrogallol B-ring of (−)-robinetinidol serving as nucleophile competing with its resorcinol A-ring in coupling with a C-4 carbocationic intermediate. Similar condensation with
    (+)-molacacacidin-[(2 R,3 S,4 R)-2,3- trans-3,4 - trans -flavan-3,3',4,4',7-戊醇的酸催化缩合]与过量的(-)-robinetinidol [(2 R,3 S)-2,3-反式黄酮-3,3',4',5',7-戊醇]提供了一系列新的双,三和四黄酮类prosetsetindins。它们伴随有(-)-菲塞蒂尼多-(4α,2')-(-)-罗比替尼醇,其起因于(-)-罗比替尼醇的邻苯三酚B环与亲和性间苯二酚A环竞争并与间苯二酚A环竞争。 C-4碳阳离子中间体。与(+)-epifisetinidol [(2S,3S)-2,3-cis-flavan-3,3',4',7-四醇]的类似缩合导致[4,6]-黄烷间键的排他性形成,与(-)-罗比替尼同系物的“分支”性质相反,这些单元以“线性”方式排列在四类黄酮类似物中。

    The invention encompasses compositions and methods for effectively treating and/or preventing the development and/or progression of osteoarthritis and rheumatoid arthritis and for promoting overall joint health. This is accomplished by totally addressing the key multiple biochemical processes and mechanisms that lead to such disorders. The invention includes compositions comprising a combination of natural agents that safely and effectively suppress, regulate or interfere with the various biochemical processes and mechanisms that increase the risk for or lead to the development and/or progression of OA and RA. The present compositions are holistically formulated to be effective in preventing/arresting loss of and/or damage to the articular cartilage (AC) by suppressing (a) extracellular matrix (ECM) degradation, (b) chondrocyte apoptosis, and (c) inflammation of synovium through modulation of mechanisms that involve transcription factors, growth factors, kinases, antiapoptotic/apoptotic factors and deacetylases. The active agents used herein are natural materials, in particular phytonutrients (or phytochemicals), minerals and/or vitamins.

This is accomplished by addressing multiple key mechanisms that lead to such disorders. The invention includes compositions comprising a combination of agents having biological activities that effectively suppress, regulate or interfere with the various key biochemical processes and mechanisms that increase the risk for development and/or progression of osteoporosis. The present compositions and methods simultaneously promote bone formation and reduce bone resorption by (a) stimulating osteoblast formation and osteogenesis; (b) suppressing adipocyte differentiation; (c) inhibiting osteoclast formation; and (d) increasing apoptosis of osteoclasts. The inventive compositions used for administration to human and other mammalian subjects having or at risk for development of osteoporosis comprise (1) at least one agent capable of modulating expression and/or activity of one or more of peroxisome activated protein receptor gamma (PPAR-γ), CAAT/enhancer binding protein-α (C/EBPα) and Sterol Regulatory Element-Binding Protein (SREBP-1); (2) at least one agent that activates expression and/or activity of one or more of the osteogenic transcription factors (Runx2/Cbfα1, Dlx5, Osterix, Msx2); (3) at least one agent that activates expression and/or activity of one or more of bone morphogenetic proteins (BMPs: BMP 2 and 4), alkaline phosphatase (ALP), and osteocalcin; (4) at least one agent capable of activating Wnt/β-catenin signaling pathway; (5) at least one agent that inhibits the activity of pro-oxidants including reactive nitrogen species and reactive oxygen species (ROS); (6) at least one agent that suppresses one or more of inflammatory mediators including interleukins IL-1α, IL-1β, IL-6, NF-κB, TNF-α, matrix metalloproteinases (MMPs) and prostaglandin E2 (PGE2); and (7) at least one agent that induces the expression of and/or activates one or more of adenosine monophosphate-activated protein kinase (AMPK), sirtuin (SIRT1) and adiponectin (AP).
