Lycopene is a carotenoid drug that has demonstrated several properties, including antioxidant and anti-inflammatory activity. The absorption in human body is very low (10-30 % only). In order to increase the bioavailability, lycopene nanoemulsion was formulated and characterized (atomic force microscopy, thermogravimetric analysis dynamic light scattering and differential scanning calorimetry). Also in vitro assay to evaluate the at-binding with MPR1 was performed. Finally, in vivo assay in animals inducted with rheumathoid arthritis were performed. The results showed that the formulated nanolycopene had superior efficacy when compared with the conventional lycopene (not nano-formulated) in inducted animals (rheumatoid arthritis). The results support the use of nanolycopene as an anti-inflammatory agent for rheumatoid arthritis therapy.
番茄红素是一种类胡萝卜素药物,具有多种特性,包括抗氧化和抗炎活性。人体对其的吸收率非常低(仅有 10-30%)。为了提高其生物利用度,制备并表征了番茄红素纳米乳(原子力显微镜、热重分析、动态光散射和差示扫描量热法)。还进行了体外试验以评估与 MPR1 的结合。最后,在诱导类风湿关节炎的动物体内进行了试验。结果表明,与常规番茄红素(非纳米制剂)相比,所制备的纳米番茄红素在诱导的动物(类风湿关节炎)中具有更好的疗效。这些结果支持将纳米番茄红素用作类风湿关节炎治疗的抗炎药物。
