being mainly distributed in the OP. Therefore, D‐SCAKG produced a stable form of esterified butyric acid as M‐SCAKG after in vitro intestinal digestion, unlike TB. Additionally, such a product would integrate both bioactive compounds, butyric acid and alkylglycerol, within the same molecule. Free butyric acid and AKG would be also released, which are lipid products of interest as well.
丁酸由于其生物活性而在去年受到了广泛的关注。然而,丁酸酯的潜在优势受到达到足够血浆浓度的问题的限制。因此,已提出前药可以替代天然丁酸酯。2,3-地丁油-1- O体外肠内消化的比较研究进行了十八酸甘油(D-SCAKG)和三丁酸甘油酯(TB)作为丁酸的潜在前药的研究。在消化的不同时间取等分试样以研究两种底物的水解程度和速率。分离消化介质中形成的胶束相(MP)和油相(OP),并分析它们在脂质产物中的组成。最初,通过以橄榄油作为标准脂质进行测试,证实了体外模型可再现生理结果。D‐SCAKG的体外肠道消化进程比TB慢。TB完全水解成丁酸,而D-SCAKG主要产生2-丁醛油-1- O-十八烷基甘油(M-SCAKG),其次是丁酸和1- O十八烷基甘油(AKG)。来自两种底物的MP主要由丁酸组成。D-SCAKG水解后,MP中还发现了少量的M-SCAKG和AKG,M-SCAKG主要分布在OP中。因此,与
