Abstract
本論文主要探討台灣鼠李Rhamnus formosana Matsum的中草藥中的主要成分Frangulin B抑制人類肺部纖維母細胞(WI-38) 受thrombin、endothelin-1 (ET-1)和bradykinin (BK) 引發之connective tissue growth factor (CTGF)表現之機制研究。細胞前處理Frangulin B (1-10 ?嵱) 再給予thrombin、endothelin-1 (ET-1)或bradykinin (BK)刺激,發現Frangulin B會以濃度相關方式分別抑制thrombin、ET-1和BK 所引發CTGF表現。進一步實驗證實Frangulin B沒有細胞毒性,Frangulin B (1-100 ?嵱)不會影響細胞存活率。Frangulin B (1-10 ?嵱)以濃度相關方式抑制thrombin和ET-1所誘導的signal transducer and activator of transcription 3 (STAT-3)和Janus kinase 2 (JAK-2)的磷酸化反應。然而,Frangulin B (1-10 ?嵱)卻無法抑制thrombin誘導Mitogen-activated protein kinases (MAPKs)的磷酸化反應。此外,Frangulin B (1-10 ?嵱)也以濃度相關方式抑制thrombin誘導collagen I 和alpha smooth muscle actin (??-SMA)的表現。綜合以上實驗結果顯示,Frangulin B可抑制thrombin誘導的纖維化物質產生,且經由抑制JAK-2蛋白激酶的活性而來。這些結果顯示,Frangulian B 是一個新的JAK-2的抑制劑可以發展成一種有效抑制肺部纖維化的藥物。
