Aspirin is one of the most widely used drugs in the treatment of inflammation, pain and fever. It has more recently found application in the prevention of heart attacks and stroke and is being studied as a cancer chemopreventative agent. Despite its value aspirin continues to be underutilized because it causes gastric bleeding. The technology under development potentially removes this problem. It is designed to reduce contact between the drug and the intestinal lining. An isosorbide aspirinate prodrug compound is thus provided. The compound has the general structure as shown in general formula (I) wherein Y is a C1 - C8 alkyl ester, a C1 - C8 alkoxy ester, a C3 - C10 cycloalkyl ester, an arylester, a C1 - C8 alkylaryl ester or -C(O)ORring, wherein Rring is a 5-membered aromatic or nonaromatic 5-member ring having at least one heteroatom substituted for a carbon of the ring system, which can be unsubstituted or substituted with at least one nitric oxide releasing group.
阿司匹林是治疗炎症、疼痛和发热最广泛使用的药物之一。它最近在预防心脏病和中风方面找到了应用,并且正在作为抗癌化学预防剂进行研究。尽管阿司匹林具有价值,但由于它会导致胃出血,因此其使用仍然不足。正在开发中的技术可能解决了这个问题。该技术旨在减少药物与肠粘膜的接触。因此,提供了一种异山梨醇阿司匹林前药化合物。该化合物的通用结构如通用公式(I)所示,其中Y是C1 - C8烷基酯,C1 - C8烷氧基酯,C3 - C10环烷基酯,芳基酯,C1 - C8烷基芳基酯或-C(O)ORring,其中Rring是具有至少一个杂原子代替环系统中的碳的5元芳香或非芳香5元环,该环可以是未取代的或至少取代有一个释放一氧化氮的基团。
