Telbivudine

替比夫定
Mechanism of action:
Telbivudine 是一種核苷類反轉錄酶抑制劑(nucleoside reverse transcriptase inhibitor),屬於胸苷(thymidine)類似物。Telbivudine 進入細胞後,依序被細胞的激酶磷酸化為有活性的 telbivudine triphosphate。Telbivudine triphosphate 會與 dTTP 競爭,被摻入病毒 DNA 中,抑制 HBV 的 DNA 聚合酶(DNA polymerase)或 HIV 反轉錄酶(reverse transcriptase),導致病毒 DNA 延長終止,使病毒無法完成複製。
