This study aimed to synthesize phenylpyruvic acid like structures that fit the molecular requirements of MIF with respect to keto/enol tautomerism and E/Z isomerism of the enol forms. The synthesis of 2,4-difluorophenylpyruvic acid and its azlactone precursor as potential ligands to interact with the active site of MIF is reported here. Both the E and Z isomers of the azlactone of 2,4-difluorobenzaldehyde
巨噬细胞迁移抑制因子 (MIF) 是一种与多种疾病有关的重要细胞因子,目前是药物开发的目标。本研究旨在合成符合 MIF 分子要求的苯基丙酮酸样结构,即烯醇形式的酮/烯醇互变异构和 E/Z 异构。本文报道了 2,4-二氟苯基丙酮酸及其吖内酯前体作为与 MIF 活性位点相互作用的潜在配体的合成。使用不同的合成方法合成了 2,4-二氟苯甲醛的吖内酯的 E 和 Z 异构体。这些异构吖内酯的水解产生了类似的 2,4-二氟苯基丙酮酸的烯醇/酮互变异构混合物,其中烯醇形式占主导地位。核磁共振光谱用于确认这些化合物的结构,
