Abstract
大腸癌在所有癌症中的死亡人數排名第二,發展新的治療方法以降低其致死率已成為緊迫課題。基於水膠的藥物遞送系統可精準控制抗癌分子在病灶處的釋放。然而,具備組織形狀適應性和強組織黏附性的抗癌水膠仍然缺乏。羥丁基幾丁聚醣(HBCS)具有溫度敏感性,可在接近人體溫度時原位成膠,適合用於不規則組織的形狀適應。改質柑橘果膠(MCP)是一種經過化學或酶處理的天然多醣體,在大腸癌治療中能與半乳凝集素-3(Gal-3)結合來抑制其作用,抑制癌細胞增殖、誘導凋亡並阻止其轉移。本研究進一步將MCP進行氧化開環並改質為含兒茶酚的多醣,模擬貽貝黏附蛋白結構,期望賦予水膠與組織表面產生穩定交互作用的潛力。精胺酸(Arg)作為氧化石墨烯(GO)的還原劑制備出rGO-Arg奈米複合物,除了能提升GO在近紅外光區(808 nm)之吸收能力,增強光熱療法效果外,還能在腫瘤微環境中釋放具生理活性濃度的一氧化氮(NO),有助於促進血管新生與細胞修復,為術後癒合提供潛在輔助效益。5-氟尿嘧啶(5-Fu)預先包覆於MIL-100(Fe)金屬有機框架中,並整合進水膠中,賦予水膠藥物裝載能力。綜合上述,HBCS/oxMCP-DA/rGO-Arg/5-Fu@MIL-100(Fe)水膠具備多模組功能整合潛力,為未來應用於大腸直腸癌術後局部修復與多功能治療平台的開發提供基礎。
