[structure: see text] The objective of this work was to synthesize cyclic prodrugs 1a and 1b from Aggrastat 2a and its analogue 2b, respectively, to improve their membrane permeation. Cyclic prodrugs 1a and 1b were formed using an ester bond between the -COOH group of Aggrastat or its analogue and the phenylpropionic acid linker 3 and an amide bond between the piperidinylamine and the -COOH group of
[结构:见正文]这项工作的目的是分别从Aggrastat 2a及其类似物2b合成环状前药1a和1b,以改善其膜渗透性。如方案中所述,分别使用Aggrastat或其类似物的-COOH基团与苯基丙酸连接基3之间的酯键和哌啶子胺与连接基3的-COOH基团之间的酰胺键形成环状前药1a和1b。 4。
