Accordingly, the invention discloses compounds with enhanced bioavailability for the prevention and treatment of anti-human immunodeficiency virus (HIV), anti-tuberculosis (TB), anti-Alzheimer or anti-cancer. The invention also discloses the method in synthesizing these compounds wherein the steps includes mixing curcumin, isatin derivatives or ninhydrin and proline in 20 mL methanol. The mixture was then refluxed with a solvent on a water bath and excess solvent was removed under vacuum. The residue subjected to flash column chromatography using petroleum ether: ethyl acetate mixture (4:1) as eluent to afford the product. The ratio for curcumin: isatin derivative/ninhydrin:proline is 1 :1 :2 and 1 :2:4.
因此,该发明揭示了增强生物利用度的化合物,用于预防和治疗抗人类免疫缺陷病毒(HIV)、抗结核病(TB)、抗阿尔茨海默病或抗癌症。该发明还揭示了合成这些化合物的方法,其中步骤包括将姜黄素、异色草酮衍生物或萘酚和脯氨酸混合在20毫升甲醇中。然后将混合物在水浴上用溶剂回流,并在真空下去除过量溶剂。残留物经过闪蒸柱层析,使用石油醚:乙酸乙酯混合物(4:1)作为洗脱剂,得到产物。姜黄素:异色草酮衍生物/萘酚:脯氨酸的比例为1:1:2和1:2:4。
