In particular, it is involved in binding to extracellular matrix adhesion factors as a receptor on the cell membrane in cell adhesion, and transmits extracellular information into cells. In recent years, it has also been shown that intracellular information is transmitted outside the cell, and integrins are considered to be one of the important molecules in physiological phenomena.
インテグリンスーパ一ファミリ一の一員である ανβ3 インテグリン (以後 ανβ3 と略す) は、 内皮細胞、 平滑筋細胞、 破骨細胞、 メラノーマ細胞等に発 現し、 細胞—細胞外マトリックス間の接着に関わっている。 ανβ3 は、 細胞上 のビトロネクチン受容体として同定されたが、 ビトロネクチンの他にフイブ リノ一ゲン、 フィブロネクチン等もリガンドとして結合することが示された。 ανβ3と細胞外マトリックスは、 接着因子の Arg- Gly- Asp (RGD)配列を介して 結合することが知られている。 RGD配列はフイブロネクチンの細胞接着に必要 な最小配列として同定された。 その後、 フイブリノ一ゲン、 フォンヴィルブ ランド因子、 ビトロネクチンその他の接着因子にも RGD配列が存在し、 その 配列を介して細胞に結合する。 また、 RGD 配列を認識するインテグリンも ανβ3以外に α5β1、 al lbp3、 ανβ5、 ανβΐ等の存在が知られている。  Ανβ3 Integrin (hereafter avβ3), a member of the integrin superfamily, is expressed on endothelial cells, smooth muscle cells, osteoclasts, melanoma cells, etc., and is involved in cell-extracellular matrix adhesion. ανβ3 was identified as a vitronectin receptor on cells, but it was shown that fibrinogen, fibronectin, etc. also bind as ligands in addition to vitronectin. It is known that ανβ3 and extracellular matrix bind via the Arg-Gly-Asp (RGD) sequence of the adhesion factor. The RGD sequence was identified as the minimal sequence required for fibronectin cell adhesion. Subsequently, the RGD sequence is also present in fibrinogen, von Willebrand factor, vitronectin and other adhesion factors, and binds to cells via that sequence. It is also known that integrins that recognize the RGD sequence include α5β1, allbp3, ανβ5, ανβΐ, etc. in addition to ανβ3.
血管内皮細胞が細胞外マトリックス上を移動することが血管新生のメカ二 ズムの一つであり、 その際インテグリンと細胞外マトリックスの結合が重要 な働きを果たしている。 創傷部位の血管内皮細胞において ανβ3 が高発現して おり、 実際に正常の血管に比べ腫瘍あるいは炎症部位の新生血管で ανβ3 が高 発現している (Brooks et al., Science. 264, 569-571, 1994) 。 ανβ3 阻害 抗体並びに ανβ3 を阻害する RGD含有ペプチドは、 鶏卵しょう尿膜の血管新生 を阻害し、 その作用は ανβ3 の阻害により内皮細胞がアポトーシスを起こすた めと考えられた (Brook et al, Cell, 79 (1994), 1157-1164) 。 ανβ3 の阻害 は、 血管新生を阻害するとともに腫瘍のサイズを小さくし (Brook et al, Cell, 79(1994), 1157-1164) 、 ανβ3 阻害抗体が担癌ヌードマウスで癌増殖 抑制作用を示した (Brooks et al., J. Clin. Invest. 96, 1815-1822,One of the mechanisms of angiogenesis is that vascular endothelial cells migrate on the extracellular matrix, and the binding of integrin to the extracellular matrix is important. Playing a role. Ανβ3 is highly expressed in vascular endothelial cells at the wound site, and ανβ3 is actually highly expressed in neovascular vessels at tumor or inflamed sites compared to normal blood vessels (Brooks et al., Science. 264, 569-571). , 1994). ανβ3 inhibitory antibodies and RGD-containing peptides that inhibit ανβ3 inhibit angiogenesis of the chicken allantois membrane, and its action is thought to be due to the inhibition of ανβ3 causing apoptosis of endothelial cells (Brook et al, Cell, 79 (1994), 1157-1164). Inhibition of ανβ3 inhibits angiogenesis and reduces tumor size (Brook et al, Cell, 79 (1994), 1157-1164), and ανβ3 inhibitory antibody has shown a tumor growth inhibitory effect in tumor-bearing nude mice (Brooks et al., J. Clin. Invest. 96, 1815-1822,
1995) 。 また、 マウス網膜症モデルにおいて ανβ3を阻害する RGD含有べプチ ドが網膜での血管新生を抑制した (Ha匪 es et al., Nature Med. 2, 529-533,1995). In addition, in a mouse retinopathy model, an RGD-containing peptide that inhibits ανβ3 suppressed angiogenesis in the retina (Ha Bandes et al., Nature Med. 2, 529-533,
1996) 。 これらの報告から、 ανβ3 阻害剤はその病態に血管新生の関与する、 癌、 関節炎、 リウマチ、 網膜症、 乾癬などの疾患の治療薬として期待されて いる。 1996). Based on these reports, ανβ3 inhibitors are expected to be used as therapeutic agents for diseases involving angiogenesis in their pathology, such as cancer, arthritis, rheumatism, retinopathy, and psoriasis.
ανβ3 は癌細胞の転移に関与することから (Firaldo et al., J. Cell. Biol. 130, 441-450, 1995) 、 ανβ3 阻害剤は癌転移抑制剤となる可能性があ る。  Since ανβ3 is involved in metastasis of cancer cells (Firaldo et al., J. Cell. Biol. 130, 441-450, 1995), ανβ3 inhibitors have the potential to become cancer metastasis inhibitors.
ανβ3は破骨細胞にも発現誘導され、 ανβ3阻害抗体が破骨細胞と骨の結合を 阻害し、 骨の再吸収を阻害することが報告されている (Ross et al., J. Biol. Chei. , 268, 9901-9907, 1993) 。 また、 ανβ3 を阻害する RGD含有べ プチドが破骨細胞の接着を阻害した (Wong et al., Mol. Pharmacol. 50, 529-537, 1996) 。 ανβ3 阻害抗体並びに RGD含有ペプチドは、 甲状、 副甲状 腺を切除したラットの PTHrP 誘発高カルシウム血症モデルにおいて骨再吸収 を阻害し (Clippes et al., Endocrnology. 137, 918-924, 1996) 、 RGDをミ ミックした合成ペプチドは卵巣摘出ラットの PTHrP 誘発高カルシウム血症モ デルにおいて骨再吸収を阻害し、 骨粗鬆症を抑制した (Engleman et al., J. Clin. Invest. 99, 2284-2292, 1997) 。 これらの報告から、 ανβ3 阻害剤は 破骨細胞における骨再吸収が関与する、 骨粗鬆症、 高カルシウム血症、 変形 性骨炎、 関節炎等の治療薬として期待されている。 経皮的冠動脈形成術 (PTCA) 後の慢性期において 30-50%の頻度で再狭窄が 起こり、 傷害部位での血管平滑筋細胞の遊走、 増殖が再狭窄の成因の一つで あると考えられている。 ανβ3 は動脈硬化巣の内膜に高発現しており (Hoshiga et al., Circ. Res. 77, 1129-1135, 1995) 、 ανβ3 の阻害は平滑 筋細胞の遊走を阻害する (Bilato et al., J. Clin. Invest. 100, 693-704, 1997) 。 また、 バルーンカテーテルによる血管障害モデルにおいて、 ανβ3 を 阻害する RGD 含有ペプチドが内膜肥厚を抑制した (Choi et. al, J. Vase. Surg. 19, 125-134, 1994) 。 よって、 ανβ3 阻害剤は平滑筋細胞の遊走を阻 害し、 血管の内膜肥厚、 PTCA後の再狭窄の予防剤として期待されている。 また、 ανβ3 は細菌やウィルスが細胞に侵入する際のレセプ夕一としても作 用する (Current Biology, Vol.3(9), 596-599, 1993) ことから、 ανβ3 阻害 剤は抗ウィルス剤として有用である可能性がある。ανβ3 is also induced in osteoclasts, and it has been reported that ανβ3 inhibitory antibodies inhibit the binding of osteoclasts to bone and inhibit bone resorption (Ross et al., J. Biol. Chei , 268, 9901-9907, 1993). Also, RGD-containing peptides that inhibit ανβ3 inhibited osteoclast adhesion (Wong et al., Mol. Pharmacol. 50, 529-537, 1996). ανβ3 inhibitory antibody and RGD-containing peptide inhibited bone resorption in a PTHrP-induced hypercalcemia model in thyroid- and parathyroidectomy rats (Clippes et al., Endocrnology. 137, 918-924, 1996). Synthetic peptides mimicking RGD inhibited bone resorption and inhibited osteoporosis in PTHrP-induced hypercalcemic models in ovariectomized rats (Engleman et al., J. Clin. Invest. 99, 2284-2292, 1997). From these reports, ανβ3 inhibitors are expected to be used as therapeutic agents for osteoporosis, hypercalcemia, osteoarthritis, arthritis, etc., which involve bone resorption in osteoclasts. Restenosis occurs at a frequency of 30-50% in the chronic phase after percutaneous coronary angioplasty (PTCA), and migration and proliferation of vascular smooth muscle cells at the injury site are considered to be one of the causes of restenosis. Have been. ανβ3 is highly expressed in the intima of atherosclerotic lesions (Hoshiga et al., Circ. Res. 77, 1129-1135, 1995), and inhibition of ανβ3 inhibits smooth muscle cell migration (Bilato et al. , J. Clin. Invest. 100, 693-704, 1997). Further, in vascular injury model by balloon catheter, RGD-containing peptides that inhibit the alpha Nyubeta3 is inhibited intimal thickening (Choi et. Al, J. Vase . Surg. 19, 125-134, 1994). Thus, alpha Nyubeta3 inhibitors impair inhibitory migration of smooth muscle cells, intimal hyperplasia of a blood vessel, is expected as restenosis preventive agent after PTCA. Ανβ3 also acts as a receptor for bacteria and viruses to enter cells (Current Biology, Vol. 3 (9), 596-599, 1993) .Therefore, ανβ3 inhibitors are used as antiviral agents. Could be useful.
