Abstract

A complex of curcumin and lecithin developed to improve the solubility of curcumin, enhanced its chondroprotective effect via an anti-inflammatory mechanism. In macrophage, proinflammatory cytokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, prostaglandin E2 (PGE2), and nitric oxide (NO) were quantified. In addition, the activity of nuclear factor (NF)-κB was examined. With chondrocytes, inflammatory mediators were assessed by measuring the secretion levels of IL-6, IL-8, and PGE2, also the mRNA expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS). Metalloproteinases (MMPs), tissue inhibitor of metalloprotease (TIMP)-1, type II collagen (COL2), proteoglycan (PG), and hyaluronic acid (HA) were measured with respect to the articulation surface. The complex promoted the anti-inflammatory effect by the inhibition of inflammatory mediators. In addition, mRNA expression levels ameliorated. Furthermore, it was effective in decreasing extracellular secretion of polypeptides, also corresponding intracellular MMPs and TIMP-1. In conclusion, the complex may be developed as a functional supplement to maintain articulation health.

摘要

一种为提高姜黄素溶解度而研发的姜黄素与卵磷脂复合物,通过抗炎机制增强了其软骨保护作用。在巨噬细胞中,对促炎细胞因子进行了定量分析,如肿瘤坏死因子(TNF)-α、白细胞介素(IL)-1β、IL-6、前列腺素E2(PGE2)和一氧化氮(NO)。此外,还检测了核因子(NF)-κB的活性。对于软骨细胞,通过测量IL-6、IL-8和PGE2的分泌水平,以及环氧化酶-2(COX-2)和诱导型一氧化氮合酶(iNOS)的mRNA表达来评估炎症介质。针对关节表面测量了金属蛋白酶(MMPs)、金属蛋白酶组织抑制剂(TIMP)-1、II型胶原蛋白(COL2)、蛋白聚糖(PG)和透明质酸(HA)。该复合物通过抑制炎症介质促进了抗炎作用。此外,mRNA表达水平得到改善。此外,它在减少多肽的细胞外分泌以及相应的细胞内MMPs和TIMP-1方面有效。总之,该复合物可开发成为一种维持关节健康的功能性补充剂。
