Abstract
光敏感性是藥物常見的不良影響,本研究第一部份為尼卡迪平的光分解反應,尼卡迪平暴露於汞燈下,以LC/MS鑑定共8個光分解產物,主產物為4-(3'-硝基苯基)吡啶衍生物(NIC-7)。尼卡迪平於照光後進行一系列的硝基還原反應,並提出其可能的反應途徑。

研究第二部份目的是選擇特定之非固醇類抗發炎藥物(氟白普洛芬與吲哚美洒辛)在醇類溶媒中以汞燈照射探討其光解情形,以GC/MS與LC/MS進行其光解產物結構之鑑定,並檢查吲哚美洒辛及其產物一些藥理作用。總計以GC/MS與LC/MS光譜分析氟白普洛芬與吲哚美洒辛於甲醇溶媒中之光分解,各鑑定出10個與4個光解產物,並進而推測其反應途徑。在藥理研究方面,吲哚美洒辛比較其所衍生之光解產物,具有最強的氫氧自由基與黃嘌呤氧化酵素抑制活性,IC50各為 65 µM與86 µM。此外,吲哚美洒辛甲基酯衍生物(IN-3)其在LPS刺激RAW 264.7巨噬細胞誘導發炎的實驗模式中具有優於IN的抑制NO及PGE2生成與iNOS及COX-2蛋白表現的能力,類似一般NSAIDs的作用。對HL-60之細胞毒殺效果是以MTT法檢驗,結果顯示HL-60細胞毒殺IC50為36.9 g/mL,效果強於IN。再者,由生化檢驗發現IN-3會引起HL-60細胞凋亡、DNA 裂解,並增強PARP與pro-caspase 3的裂解作用,以上結果支持光解產物IN-3具有優於母藥吲哚美洒辛的抗發炎(LPS刺激RAW 264.7巨噬細胞)及細胞毒殺(HL-60)效果。
