Curcumin, the bioactive component of turmeric, Curcuma longa has an exceptionally wide spectrum of activities including antioxidant, anti-inflammatory and anti-cancer properties, and is currently under different phases of clinical trials for various types of soft tissue cancers. However, although in vitro and animal studies have shown anticancer activities of curcumin for virtually all types of human cancers, its poor bioavailability in the human body has severely limited its application to these diseases. Methods to increase its oral bioavailability are a subject of intense current research. Reconstituting curcumin with the non-curcuminoid components of turmeric has been found to increase the bioavailability substantially. In the present clinical study to determine the bioavailability of curcuminoids, a patented formulation, BCM-95((R))CG was tested on human volunteer group. Normal curcumin was used in the control group. Curcumin content in blood was estimated at periodical intervals. After a washout period of two weeks the control group and drug group were crossed over BCM-95((R))CG and curcumin, respectively. It was also compared with a combination of curcumin-lecithin-piperine which was earlier shown to provide enhanced bioavailability. The results of the study indicate that the relative bioavailability of BCM-95((R))CG (Biocurcumax) was about 6.93-fold compared to normal curcumin and about 6.3-fold compared to curcumin-lecithin-piperine formula. BCM-95((R))CG thus, has potential for widespread application for various chronic diseases.
姜黄素是姜黄(Curcuma longa)的生物活性成分,具有极为广泛的活性,包括抗氧化、抗炎和抗癌特性,目前正处于针对各类软组织癌的不同临床试验阶段。然而,尽管体外和动物研究表明姜黄素对几乎所有类型的人类癌症都具有抗癌活性,但其在人体中的低生物利用度严重限制了它在这些疾病中的应用。提高其口服生物利用度的方法是当前研究的热点。已发现将姜黄素与姜黄的非姜黄素类成分复配可大幅提高生物利用度。在本项测定姜黄素类生物利用度的临床研究中,一种专利配方BCM-95((R))CG在人类志愿者组中进行了测试。对照组使用普通姜黄素。定期测定血液中的姜黄素含量。经过两周的洗脱期后,对照组和药物组分别交叉使用BCM-95((R))CG和姜黄素。还将其与先前显示能提高生物利用度的姜黄素-卵磷脂-胡椒碱组合进行了比较。研究结果表明,与普通姜黄素相比,BCM-95((R))CG(Biocurcumax)的相对生物利用度约为6.93倍,与姜黄素-卵磷脂-胡椒碱配方相比约为6.3倍。因此,BCM-95((R))CG在各种慢性疾病中具有广泛应用的潜力。
