Description
本發明係關於一種木棉花水萃物的用途,特別關於一種木棉花水萃物應用於製備抗藥性B型肝炎治療用藥物的用途。
B型肝炎(hepatitis B)係為一種國人常見之疾病,成人中約有15%體內帶有B型肝炎病毒(hepatitis B virus),且B型肝炎病毒造成之慢性肝病、肝硬化(cirrhosis)及肝癌(hepatocellular carcinoma)等衍生疾患,更是位居國人十大死因之榜首。
肝安能(Lamivudine)為一種用以治療B型肝炎之習用藥物,肝安能係屬於胞苷類似物(cytidine analogue),可以抑制B型肝炎病毒之反轉錄酶,進而抑制B型肝炎病毒之複製。惟,肝安能用於治療慢性B型肝炎時,卻容易因為療程較長,使B型肝炎病毒發生突變,而產生抗藥性病毒株,可能會使肝安能之治療效果變得不佳,是以,確實仍有必要發展新的抗B型肝炎藥物。
為解決上述問題,本發明提供一種木棉花水萃物的用途,係將萃取自木棉花之活性成分,應用於製備B型肝炎治療用的藥物者。
本發明之木棉花水萃物的用途,係應用於製備抗藥性B型肝炎治療用的藥物,其中,該木棉花水萃物係水於115~125℃之溫度、0.35~0.5Kg/cm2G之壓力下萃取1.5~3小時所獲得,且該抗藥性B型肝炎係由對肝安能具有抗藥性之抗藥性B型肝炎病毒株所誘發;如此藉由萃取自
木棉花之活性成分,可以抑制抗藥性B型肝炎病毒之複製,清除體內之抗藥性B型肝炎病毒,因而可以應用於製備抗藥性B型肝炎治療用的藥物,為本發明之功效。
第1圖:投予本發明木棉花水萃物對野生型B型肝炎病毒株之e抗原的影響結果柱狀圖。
第2圖:投予本發明木棉花水萃物對抗藥性B型肝炎病毒株之e抗原的影響結果柱狀圖。
為讓本發明之上述及其他目的、特徵及優點能更明顯易懂,下文特舉本發明之較佳實施例,並配合所附圖式,作詳細說明如下:
本發明所述之「木棉(Bombax malabaricum DC.)」,係指木棉科(Bombacaceae)木棉屬(malabaricum)的植物,其花朵(即,木棉花)清熱解毒,常被用於煲湯。
本發明之木棉花水萃物,係可以抑制抗藥性B型肝炎病毒之複製,清除體內之抗藥性B型肝炎病毒,因而可以應用於製備抗藥性B型肝炎治療用的藥物,該木棉花水萃物與醫藥學上可以接受之載劑或賦形劑組合形成一醫藥組合物,其中,該木棉花水萃物係可以製備成任何方便食用之型式,如錠劑、膠囊、粉劑、粒劑或液劑等,或者將該木棉花水萃物與其他食品或飲料組合,以適於食用之樣態供生物體以口服方式服用。
其中,該木棉花水萃物較佳係可以藉由一包含以下步驟之方法所製得:提供一木棉花樣品;以水作為一萃取溶劑萃取該木棉花樣品;及將木棉花粗萃液進行濃縮,以獲得該木棉花水萃物。
詳而言之,係可以預先將該木棉花樣品於110~120℃之溫度
下進行乾燥(將100克木棉花樣品乾燥至20克),得到一木棉花乾燥物;此外,該木棉花樣品亦可以預先碎成粉粒(粒徑約為1~2mm),以增加該木棉花樣品與該萃取溶劑之接觸表面積,藉此提升後續萃取之萃取效率。
舉例而言,每4.8kg之木棉花樣品係能夠混合該萃取溶劑,使二者總體積達80L,並於115~125℃之溫度、0.35~0.5Kg/cm2G之壓力下進行萃取1.5~3小時,上述萃取亦可以重複數次,使該木棉花樣品所富含之活性成分可以完整溶出於該萃取溶劑,此為本發明所屬技術領域中具有通常知識者所廣泛應用,在此不加以贅述。
前述之木棉花粗萃液可以經過減壓濃縮及冷凍乾燥,以獲得該木棉花水萃物,藉由此一程序,係可以使該木棉花水萃物之活性成分更加濃縮,是以僅需使用少量之該木棉花水萃物即可以發揮最佳療效。
為證實本發明之木棉花水萃物係可以清除B型肝炎病毒,遂進行以下試驗,其中,以下試驗除選用野生型B型肝炎病毒株外,另選用對習用藥物肝安能具有抗藥性之抗藥性B型肝炎病毒株進行試驗,於此先行敘明。
(A)木棉花水萃物清除野生型B型肝炎病毒之效果
請參照第1表所示,本試驗係分別以不同濃度之木棉花水萃物處理野生型B型肝炎病毒株48小時後,以ELISA之方式偵測各組培養液之e抗原(HBeAg)含量,其結果如第1圖所示。
請參照第1圖所示,無論是添加濃度為6.25~50μL/mL之木棉花水萃物,對於野生型B型肝炎病毒株均有良好之抑制效果,顯示本發明之木棉花水萃物係可以抑制該野生型B型肝炎病毒株之複製,以達到清除B型肝炎病毒之功效。
(B)木棉花水萃物清除抗藥性B型肝炎病毒之效果
請參照第1表所示,本試驗係分別以不同濃度之木棉花水萃物處理抗藥性B型肝炎病毒株48小時後,以ELISA之方式偵測各組培養液之e抗原(HBeAg)含量,其結果如第2圖所示。
請參照第2圖所示,無論是添加濃度為6.25~25μL/mL之木棉花水萃物,對於抗藥性B型肝炎病毒株均有良好之抑制效果,顯示本發明之木棉花水萃物係可以抑制該抗藥性B型肝炎病毒株之複製,以達到清除抗藥性B型肝炎病毒之功效。
綜合上述試驗結果,木棉花水萃物可以有效抑制B型肝炎病毒株之複製,因而可以清除生物體內之B型肝炎病毒,以達到治療B型肝炎之功效;此外,針對抗藥性B型肝炎病毒株,木棉花水萃物仍可以抑制其複製,進而可以作為肝安能之第二線藥物,於肝安能之投藥導致抗藥性
病毒株之產生後,仍可以有效抑制該抗藥性病毒株之複製,而可以有效治療抗藥性B型肝炎,降低抗藥性B型肝炎之發生率。
綜合上述,本發明之木棉花水萃物的用途係藉由萃取自木棉花之活性成分,可以抑制抗藥性B型肝炎病毒之複製,清除體內之抗藥性B型肝炎病毒,因而可以應用於製備抗藥性B型肝炎治療用的藥物,為本發明之功效。
再者,本發明之木棉花水萃物的用途,係藉由萃取自木棉花之活性成分,有效減少生物體被抗藥性B型肝炎病毒感染的風險,進而可以預防慢性肝病、肝硬化、肝代償不全及肝癌等疾病的衍生,為本發明之功效。
雖然本發明已利用上述較佳實施例揭示,然其並非用以限定本發明,任何熟習此技藝者在不脫離本發明之精神和範圍之內,相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇,因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。
