products from herbal medicines and dietary plants constitute the main source of lead compounds for the development of the new drug. 4,4-Dimethylcurcumin (DMCU) is a synthetic curcumin derivative and exhibits anticancer activities against breast, colon, lung, and liver cancers. However, further development of DMCU is limited by unfavorable compound properties such as very low aqueous solubility and moderate
来自草药和食用植物的天然酚类产品构成了开发新药的先导化合物的主要来源。4,4-二甲基姜黄素( DMCU ) 是一种合成姜黄素衍生物,对乳腺癌、结肠癌、肺癌和肝癌具有抗癌活性。然而,DMCU 的进一步开发受到不利的化合物性质的限制,例如极低的水溶性和中等稳定性。以增加其溶解度,我们要么安装或两者的乙烯碳酸酯连接的L-缬氨酸侧链的DMCU酚基团和产生的有针对性的1 -三氟乙酸(1-TFA)和2 -三氟乙酸( 2-TFA )衍生物。已知碳酸亚乙酯连接侧链的末端 L-缬氨酸是 L 型氨基酸转运蛋白 1 (LAT1) 识别元件,因此,预计这两种衍生物很容易进入表达 LAT1 的癌细胞。在实践中,1-TFA或2-TFA是由DMCU分四步合成的,总产率为 34-48%。根据相应的 LC-MS 分析,DMCU、1-TFA和2-TFA在室温 (25 ± 1 °C) 下的水溶性分别为 0.018、249.7 和
