「基孔肯雅病」是現今廣泛流行的傳染性疾病之一，且近年有從非洲和南亞蔓延到歐洲和日本的趨勢。目前世上還未有防治此症的疫苗或藥物，治療方式只能減輕該症狀。我們合成出具有抗「基孔肯雅病毒」的「香荳素共軛含氮鹼基化合物」，並成功的運用「聚乳酸–甘醇酸」（poly(lactic-co- glycolic acid)，即PLGA）包覆形成奈米粒子，作為藥物載體。
合成出的「香荳素共軛含氮鹼基化合物」抗「基孔肯雅病毒」之EC50最佳值為12.3 μM，本人使用24.4–40.6 KD、40.6–57.8 KD和49.67–69.58
KD三種不同分子量大小的PLGA做為包覆材料，利用「奈米沉澱法」（nanoprecipitation）製備包覆有「香荳素共軛化合物」PLGA奈米粒子大小，形成為200–450 nm之微胞，最高包覆效率（encapsulation efficiency，即EE）達55.3%。
本人測試發現被包覆之藥物濃度比「香荳素共軛化合物」在水中之濃度多達82–207倍，最多達兩個量級，此結果可以提高「香荳素共軛化合物」在作為口服藥的使用效率。
