BACKGROUND
種々の急性及び慢性炎症において、 共通して認められる病態は炎症組織 への白血球の浸潤である。 生理的状態で血液中の白血球はリンパ球を除い て血管から外へ出ること、 すなわち組織へ浸潤することはなく、 炎症のよ うな病態が生じた場合のみ白血球は血管壁を通り抜けて、 組織へ浸潤する ことが可能である。 In a variety of acute and chronic inflammations, a common condition is the infiltration of leukocytes into inflamed tissues. Leukocytes in blood exclude lymphocytes under physiological conditions It does not escape from blood vessels, ie, does not invade tissues, and leukocytes can penetrate the blood vessel walls and infiltrate tissues only when a condition such as inflammation occurs.
白血球の浸潤は、 サイ ト力イン、 ケモカイン、 リピッ ド及び補体等によ つて惹起される。 これらの物質によって活性化した白血球は、 同様に活性 化した血管内皮細胞上をころがり(rolling), 強固に接着し(adhes i on)、そ して血管内皮細胞間隙を通り抜けて組織へ浸潤して行く(transmigration) この白血球と血管内皮細胞との相互作用の過程にはセレクチンファミリ一、 インテグリンファミリ一、 ィムノグロブリンフアミリーと呼ばれる細胞接 着分子が関与している。 細胞接着分子は白血球及び血管内皮細胞の両方に 発現していて、 互いに特異的な組み合わせで結合することができる [Springer TA, Cell, 76, 301-314 (1994) ) 0 血管内皮細胞に発現する細胞 接着分子のうち、 E—セレクチン及び V CAM— 1は生理的状態では発現 していないが、 例えば TN F— α、 I L_ 1、 リポポリサッカライ ド等の 炎症性の刺激を受けると急速に細胞表面に発現する。 一方、 白血球の表面 にはひ鎖と /3鎖から構成されるへテロダイマーであるィンテグリンが発現 していて、 炎症性の刺激によって立体構造を変化させることにより、 血管 内皮細胞に発現する細胞接着分子と結合することが可能となる。 また、 好 中球に発現しているインテグリン Mac- 1は炎症性刺激によって発現が増大 し、 血管内皮細胞への接着を増強する 〔Carlos TM ら, Blood, 84, 2068- 2101 (1994)〕。 Leukocyte infiltration is triggered by site force, chemokines, lipids and complement. Leukocytes activated by these substances roll on the similarly activated vascular endothelial cells, adhere tightly, and infiltrate the tissue through the vascular endothelial cell gap. Transmigration In the process of interaction between leukocytes and vascular endothelial cells, cell adhesion molecules called selectin family 1, integrin family 1, and immunoglobulin family are involved. Cell adhesion molecules are expressed on both leukocytes and vascular endothelial cells, [Springer TA can be coupled with each other specific combinations, Cell, 76, 301-314 (1994 )) expressed on 0 endothelial cells Among cell adhesion molecules, E-selectin and VCAM-1 are not expressed in physiological conditions, but rapidly when exposed to inflammatory stimuli such as TNF-α, IL_1, and lipopolysaccharide. Is expressed on the cell surface. On the other hand, leucocytes express integrins, which are heterodimers composed of splice chains and / 3 chains, on the surface.The cell adhesion molecule expressed on vascular endothelial cells by changing the three-dimensional structure by inflammatory stimulation Can be combined. In addition, the expression of integrin Mac-1 expressed in neutrophils is increased by inflammatory stimuli and enhances adhesion to vascular endothelial cells [Carlos ™ et al., Blood, 84, 2068-2101 (1994)].
また、 癌の転移は癌組織から離脱した癌細胞が標的臓器の血管内皮細胞 に接着し、 組織内へ浸潤することで成立すると考えられていて、 種々の細 胞接着分子が関与していることが報告されている 〔BevilacquaMP, Annual Review Immunology, 11, 767-804 (1993) ] 0 以上のことから、 炎症組織において炎症性刺激によって誘導される種々 の細胞接着分子の発現を抑制する物質は、 種々の急性及び慢性炎症疾患及 び癌の転移に対して有効な薬剤になると考えられる。 In addition, cancer metastasis is thought to be established by cancer cells detached from cancer tissue adhering to vascular endothelial cells of the target organ and infiltrating into the tissue, and various cell adhesion molecules are involved. [BevilacquaMP, Annual Review Immunology, 11, 767-804 (1993)] 0 Based on the above, it is considered that substances that suppress the expression of various cell adhesion molecules induced by inflammatory stimuli in inflamed tissues will be effective drugs for various acute and chronic inflammatory diseases and cancer metastasis .

The test compound was dissolved in Hanks' solution (Nissui Pharmaceutical) and added to HUVEC one hour before the addition of LPS (final concentration of test compound was 50 ^ g / ml). To the collected HUVEC, a mouse anti-human E-selectin antibody (IgGl) (Seikagaku Corporation) was added as a primary antibody, and the mixture was left on ice for 30 minutes. After washing, a phycoerythrin-conjugated hidge anti-mouse IgG antibody (Cosmo Bio) was added as a secondary antibody, and allowed to stand on ice for 30 minutes for labeling. E-selectin expression was measured using a flow cytometer (Corta-1). The inhibition rate was determined by using the average fluorescence intensity of HUVEC stimulated with LPS (a) and the average fluorescence intensity of non-stimulated HUVEC (c) as the maximum and minimum expression levels, respectively, using LPS stimulation in the presence of the test compound. The average fluorescence intensity of HUVEC (b) was calculated according to the following formula, and the results are shown in Table 1 below.
抑制率 (%) = [l-(b-c)÷(a-c)] X 100  Suppression rate (%) = [l- (b-c) ÷ (a-c)] X 100
