以脂質和酒精為主材料而形成的液胞結構即稱為乙醇體(ethosome),研究證實其可促進藥物滲透率。本研究致力於發展類乙醇體陰陽離子液胞(ethosome-like catanionic vesicle)作為藥物經皮傳輸用之載體;首先利用沉澱法形成三種類脂質結構的離子對雙親分子(ion-pair-amphiphile, IPA),分別為DeTMA-DS、DeTMA-TS以及DTMA-DS,藉由乙醇為共溶劑的半自發製程,在pH值為7.4的緩衝溶液環境中製備三種類乙醇體陰陽離子液胞;此外,以液胞包覆維他命E醋酸酯(dl-α-tocopheryl acetate, α-TA),並利用具疏水基團修飾的水溶性高分子作為增稠劑,模擬藥物傳輸的潛力與應用性。
實驗結果顯示,添加膽固醇可以增加三組液胞系統的穩定性;藉由示差掃描熱卡計(differential scanning calorimetry)可獲得三種IPA系統的雙層膜相轉移溫度,配合螢光偏極化(fluorescence polarization)實驗,發現具相對較低相轉移溫度的DeTMA-DS與DeTMA-TS系統而言,其雙層膜剛性(membrane rigidity)隨膽固醇濃度增加而增加;反之,具有相對較高相轉移溫度DTMA-DS系統,其雙層膜剛性隨膽固醇濃度增加而些微下降。進一步研究發現,維他命E醋酸酯的包覆效率和釋放速率分別與雙層膜剛性呈現正和負相關的趨勢。另外,藉由動態流變儀分析液胞與疏水性高分子膠化後之流變性質,當雙層膜剛性越強時,液胞雙層膜疏水性也越強,進而提升包覆效率。而藥物釋放驅動力可能是藉由雙層膜內外藥物濃度梯度而擴散出去,若雙層膜處於較規則排列狀態時,藥物透過雙層膜擴散至外界的阻力較大,因而抑制釋放效率。
A carrier for enhancing skin delivery of drugs had been discovered and named ‘‘ethosome,’’ which was phospholipid vesicular system embodying ethanol in relatively high concentrations. This work aimed at developing competent ethosome-like catanionic vesicles for dermal drug delivery. Three kinds of lipid-like ion-pair-amphiphiles, IPAs, were prepared by the precipitation method. They were DeTMA-DS, DeTMA-TS and DTMA-DS, respectively, and were thereafter used as the new raw materials to prepare the ethosome-like catanionic vesicles with the aid of ethanol as the cosolvent in aqueous buffer solution whose pH value was 7.4 by a simple semispontaneous process. In addition, the potential applications of the catanionic vesicles as nano-carriers in dermal drug delivery were demonstrated by the encapsulation of vitamin E acetate (α-tocopherol acetate, α-TA) and used a kind of water-soluble polymer with hydrophobic modification as a thickener to improve the viscosity of vesicular dispersion.
The experimental results revealed that the vesicle stability could be enhanced by the addition of cholesterol. The bilayer membrane phase transition temperatures of three kinds of IPAs were detected via DSC. Cooperating with the results of fluorescence polarization analysis, we find that the bilayer membrane rigidity for DeTMA-DS and DeTMA-TS systems with relatively lower phase transition temperatures increased with the addition of cholesterol. On the other hand, the bilayer membrane rigidity for DTMA-DS system with relatively higher phase transition temperatures slightly decreased with the addition of cholesterol. Moreover, the encapsulation efficiency and released rate of Vitamin E acetate positively and negatively, respectively, correlated to the bilayer membrane rigidity. Finally, analyze the rheological properties by dynamic rheometer to study the hydrophobic interaction between vesicles and polymers. The more rigid bilayer membrane resulted in the stronger hydrophobic interactions, indicating that the more rigid bilayer membrane possessed the stronger bilayer hydrophobicity as well as the higher encapsulation efficiency. As to the driving force of releasing drug might be the concentration gradient of Vitamin E acetate. The more rigid bilayer membrane could hinder the diffusion of drugs and result in the lower released rate.
