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 pipecolinic acid in 20 m L 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: pipecolinic acid is 1:1:2 and 1:2:4.
因此,本发明揭示了一种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。本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、异色烟酰肼衍生物或吡啶甲酸混合在20毫升甲醇中。然后将混合物在水浴上用溶剂回流,并在真空下去除多余的溶剂。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:异色烟酰肼衍生物/吡啶甲酸的比例为1:1:2和1:2:4。
