Description

【0001】
【発明の属する技術分野】
本発明は、アミド化合物を含有する、コラーゲン蓄積促進及び/又は減少抑制のための組成物等に関する。
【0002】
【従来の技術】
体の中で最も大量に存在するタンパク質であるコラーゲン、特にその中で存在量の最も多いI型コラーゲンの主たる役割は、線維性成分としての力学的支持性である。各種臓器の構成細胞の1つである線維芽細胞は、コラーゲン、エラスチン、フィブロネクチン等の線維状タンパク質やヒアルロン酸等のグリコサミノグルカン等を産生し、これら細胞外マトリックスが3次元的な構造を形成することにより、組織が保持、維持されている。そのため、コラーゲンの質的量的な変化は力学的支持体としてのコラーゲン線維の機能的変化をもたらし、例えば、I型コラーゲンが有機成分の中心を占める骨基質ではコラーゲン量の減少に伴い、その脆弱化が起こると考えられている。また、加齢や紫外線等によって皮膚に生じるしわ等の組織容態や、異常創傷治癒、歯周病、骨粗しょう症、慢性関節リウマチ等の疾患においては、コラーゲン合成の低下とコラーゲン分解の促進とがそれら疾患又は組織容態の遷延に影響している(例えば、非特許文献1乃至5参照)。
実際、レチノイン酸、ビタミンC類、1α,25−ジヒドロキシビタミンD、安息香酸化合物等の公知のコラーゲン合成促進剤を外用剤として用いることにより、しわ等の組織容態が改善されることがすでに報告されている(例えば、非特許文献6及び非特許文献7、並びに特許文献1参照)。また、骨粗しょう症等の疾患を改善させるエストロゲンは、骨芽細胞のコラーゲン合成を促進し、しかもマトリックスメタロプロテアーゼ(MMP)−1(以下、MMP−1と記載することもある。)の産生を抑制することがすでに報告されている(例えば、非特許文献8及び非特許文献9参照)。
【0003】
組織中のコラーゲン量は、合成と分解とのバランスにより既定されるが、それらは種々の細胞増殖因子、サイトカイン、低分子化合物等によって調節されている。例えば、サイトカインの1種であるTGF−βはよく知られたコラーゲン等の細胞外マトッリクスの発現促進因子であるが、一方では、コラーゲンの分解を触媒する各種マトリックスメタロプロテアーゼ(MMPs)の発現抑制因子でもある。具体的には、例えば、TGF−βはヒト肺線維芽細胞のI、III、V型コラーゲンの産生や、ヒト胎児線維芽細胞のフィブロネクチンの産生を高める一方、MMP−1、MMP−2及びMMP−9の産生を抑制する(例えば、非特許文献10及び非特許文献11参照)。
また動物個体レベルにおける研究において、TGF−βトランスジェニックマウスでは創傷治癒の促進が起こり、さらに、TGF−β遺伝子をリウマチモデル動物に導入したところ、当該疾患が改善したことが報告されている(例えば、非特許文献12参照)。
以上のことから、コラーゲン合成の促進とコラーゲン分解の抑制により、コラーゲン蓄積促進及び/又は減少抑制の効果を有する低分子化合物は、しわ、異常創傷治癒、歯周病、骨粗しょう症、慢性関節リウマチ等の組織中のコラーゲン量の減少を伴う疾患又は組織容態を改善させ、その結果、当該化合物を有効成分として含有する医薬品、医薬部外品、化粧品、食品等の開発につながる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a composition for promoting and / or suppressing the accumulation of collagen and the like, which contains an amide compound.
[0002]
[Prior art]
A major role of collagen, the most abundant protein in the body, and particularly type I collagen, the most abundant of it, is its mechanical support as a fibrous component. Fibroblasts, one of the constituent cells of various organs, produce fibrous proteins such as collagen, elastin and fibronectin, and glycosaminoglucans such as hyaluronic acid, and these extracellular matrices have a three-dimensional structure. The formation holds and maintains the tissue. Therefore, qualitative and quantitative changes in collagen result in functional changes in collagen fibers as a mechanical support.For example, in a bone matrix in which type I collagen is the center of the organic component, as the amount of collagen decreases, its fragility increases. Is thought to occur. In addition, in tissue conditions such as wrinkles that occur in the skin due to aging and ultraviolet rays, and in diseases such as abnormal wound healing, periodontal disease, osteoporosis, and rheumatoid arthritis, a decrease in collagen synthesis and promotion of collagen degradation may occur. It affects the prolongation of those diseases or tissue conditions (for example, see Non-Patent Documents 1 to 5).
In fact, it has already been reported that the use of known collagen synthesis promoters such as retinoic acid, vitamin Cs, 1α, 25-dihydroxyvitamin D 3 , and benzoic acid compounds as external preparations improves tissue conditions such as wrinkles. (See, for example, Non-Patent Documents 6 and 7, and Patent Document 1). Estrogen that improves diseases such as osteoporosis promotes collagen synthesis of osteoblasts and also produces matrix metalloprotease (MMP) -1 (hereinafter sometimes referred to as MMP-1). Suppression has already been reported (for example, see Non-Patent Documents 8 and 9).
[0003]
The amount of collagen in tissues is determined by the balance between synthesis and degradation, which are regulated by various cell growth factors, cytokines, low molecular weight compounds, and the like. For example, TGF-β, one of cytokines, is a well-known factor for promoting the expression of extracellular matrix such as collagen, while, on the other hand, a factor for suppressing the expression of various matrix metalloproteases (MMPs) that catalyzes the degradation of collagen. But also. Specifically, for example, TGF-β enhances the production of type I, III, and V collagen in human lung fibroblasts and the production of fibronectin in human fetal fibroblasts, while MMP-1, MMP-2 and MMP -9 production is suppressed (for example, see Non-Patent Documents 10 and 11).
In studies at the animal individual level, it has been reported that wound healing was promoted in TGF-β transgenic mice, and that the disease was improved when the TGF-β gene was introduced into a rheumatoid model animal (for example, , Non-Patent Document 12).
Based on the above, low-molecular compounds having the effect of promoting collagen synthesis and suppressing collagen degradation to promote and / or reduce collagen accumulation can be used for wrinkles, abnormal wound healing, periodontal disease, osteoporosis, and rheumatoid arthritis. And the like, which leads to the development of drugs, quasi-drugs, cosmetics, foods and the like containing the compound as an active ingredient.
