Description
本發明係關於一種高分子組成物,且特別關於一種具有鋅離子親和力之高分子組成物,而此高分子組成物具有基質金屬蛋白酶(matrix metalloproteinases,MMPs)抑制功效,可直接以塊狀形式作為慢性傷口敷料或可用以處理醫療器材之表面,以使病患使用此慢性傷口敷料或醫療器材之時可改善組織發炎症狀及/或促進傷口癒合。
目前已知高活性及濃度之基質金屬蛋白酶(matrix metalloproteinases,MMPs)是造成慢性傷口遲遲未癒的主因。傷口的感染及發炎會引起組織大量分泌基質金屬蛋白酶以分解與移除傷口床死亡的細胞與細菌,但基質金屬蛋白酶活性過高也會新生組織的分解和生長因子的損傷,使傷口再度回到發炎期,而形成惡性循環無法癒合。上述情形於糖尿病患或其他病源性慢性病患之傷口十分常見,乃至造成病患之傷口惡化甚至截肢。此時具有基質金屬蛋白酶抑制效果之敷料可降低局部基質金屬蛋白酶活性,促進傷口癒合。
又,於各式炎症反應,如類風濕性關節炎(rheumatoid arthritis)及骨性關節炎(osteoarthritis)也均有組織大量分泌基質金屬蛋白酶的情形。高活性之基質金屬蛋白酶表現往往啟動多種生化機制,為致病機轉之一,造成軟骨破壞。此外於冠狀動脈疾病(如冠心病)和心肌損傷時,所產生
具有活性之基質金屬蛋白酶往往又進一步降解細胞外基質導致斑塊和血管壁變薄乃至破裂。此時具有基質金屬蛋白酶抑制效果之材料可作為緩解病症之功效。
此外,通常於血管新生、細胞遷移、組織新生重建時須有基質金屬蛋白酶的生成以協助細胞外基質材料的降解。然而於腫瘤生成時,過量基質金屬蛋白酶的活性表現會導致細胞外基底膜降解,而因此促進腫瘤的侵犯能力與移轉能力隨之上升,造成腫瘤細胞的擴散。此時具有抑制基質金屬蛋白酶活性之抑制劑及材料之開發可有助於減少腫瘤血管新生與轉移。
基質金屬蛋白酶為一群含有鋅離子,可分解大多數細胞外基質的多肽內切酶。其結構上含前區(prodomain)、催化中心、類血紅素結合蛋白(hemopexin)作用區段及跨膜(transmembrane)四個作用區段(domain)所組成。現今已經發現超過25種之基質金屬蛋白酶,其可約略分為四型,包括(1)膠原蛋白酶;(2)明膠酶;(3)基質溶素;與(4)膜型基質金屬蛋白酶。可有效分解人體組織中富含的明膠、膠原蛋白、與蛋白多醣等,並且與組織形成、組織新陳代謝及發炎反應有關。基質金屬蛋白酶於分泌生成時期,此時其活化位置的鋅原子與胱氨酸結合,為非活化之狀態,當多肽被切割之後打開,基質金屬蛋白酶則成為有活性之形式。
目前研究針對基質金屬蛋白酶的抑制方法主要有三種方法:(1)使用金屬蛋白酵素的組織抑制因子(tissue
inhibitor of metalloproteinase)與基質金屬蛋白酶血紅素結合蛋白形成可逆、非共價鍵結合的複合物使其失去活性;(2)以胜肽或抗體方式直接抑制基質金屬蛋白酶的活性表現;以及(3)使用與鋅離子間具有高親和性之分子以鍵結使酵素失活。其螯合鋅離子進而使基質金屬蛋白酶失去活性的機制,係藉由磷、氮、硫、氧等帶有未鍵結電子對(lone pair electrons)之原子非常容易與過渡金屬元素形成配位(coordination)形式。
由文獻及近年相關產品研發方向顯示,慢性傷口先進敷料開始訴求抑制基質金屬蛋白酶活性以促進傷口床重建癒合。此類產品以開發和傷口床接觸可抑制基質金屬蛋白酶活性的生醫材料為第三種抑制方法。以Systagenix公司的Promogran慢性傷口敷料為例,其氧化纖維素與膠原蛋白之組合基材可有效吸收傷口床滲出液,且藉由氧化纖維素酸根和鋅離子的親和力抑制酵素活性。Smith & Nephew公司亦推出慢性傷口敷料Biostep其抑制機制乃是於基材中添加具有螯合锌離子作用之EDTA,由於基質金屬蛋白酶必須藉由與鋅離子的結合來維持其活化之狀態,因此基材中游離之EDTA可有效降低鋅離子濃度,甚而吸附含鋅之基質金屬蛋白酶使之失活。然而此一螯合分子乃游離態存在,因此作用時間與效能易受限制。
因此目前亟需一種新的材料,其可長效抑制基質金屬蛋白酶之活性。
