Disclosed herein are simple and unique methods of methods of preparing liposomal compositions of N-(4-hydroxyphenyl) retinamide (4HPR) and/or other retinoids. Also disclosed are liposomal 4HPR compositions prepared by such methods, and use of such compositions in the treatment of diseases, such as breast cancer. This invention further provides methods for improving the efficacy of N-(4-hydroxyphenyl) retinamide (4HPR) as a chemopreventive agent in the presence of agents that potentiates its ability increase the expression of inducible nitric oxide synthase (iNOS, and NO production in cells.
本文披露了制备N-(4-羟基苯基)视黄酰胺(4HPR)和/或其他视黄醇脂质体组合物的简单且独特的方法。还披露了通过这些方法制备的脂质体4HPR组合物,并将这种组合物用于治疗疾病,如乳腺癌。本发明还提供了一种方法,通过增强诱导型一氧化氮合酶(iNOS)和细胞内NO产生的能力,提高N-(4-羟基苯基)视黄酰胺(4HPR)作为化学预防剂的功效。
