isolated from Paecilomyces sp. FKI-6801 for its selective IMP-1 MBL inhibitory activity. The first total synthesis of 1 from the commercially available compound was achieved in 9 steps with 28% overall yield. Introduction of catechol to the maleic anhydride of 1 improved the IC50 toward IMP-1 MBL and the inhibitory activity against IMP-1 MBL-producing P. aeruginosa. Treatment of the maleic anhydride scaffold
3Z,5E-Octa-3,5-diene-1,3,4-tricarboxylic acid-3,4-anhydride (ODTAA, 1 ) 从拟青霉属分离。FKI-6801 具有选择性的 IMP-1 MBL 抑制活性。从市售化合物中首次全合成1分 9 步完成,总收率为 28%。将儿茶酚引入1的马来酸酐提高了对 IMP-1 MBL 的 IC 50和对产生 IMP-1 MBL 的铜绿假单胞菌的抑制活性。用胺处理马来酸酐支架表明,需要 β-羰基-α,β-不饱和羧酸部分作为 IMP-1 MBL 抑制的药效团。
