Discovery and Structural Modification of Inhibitors of Methionine Aminopeptidases from Escherichia coli and Saccharomyces cerevisiae
摘要:
A series of pyridine-2-carboxylic acid derivatives were synthesized according to the leads from the screening, and potent inhibitors have been obtained by structural modification. They have shown submicromolar inhibition of the enzymes (for example, for 9n, IC50 = 130 nM for EcMetAP1 and IC50 = 380 nM for ScMetAP1). They represent small-molecule MetAP inhibitors with novel structures different from alkylating fumagillin derivatives and peptidic bestatin-based MetAP inhibitor.

4]diazepine-2,5-diones 9, is reported using the condensation of α-aminoacid methyl esterderivatives with 1H-pyrido[3,2-d][1,3]oxazine-2,4-dione and 1H-pyrido[2,3-d][1,3]oxazine-2,4-dione. Compounds 8 and 9 were also synthesized by peptide coupling of α-aminoacid methyl esterderivatives with β-amino acids (2 or 3) followed by the cyclisation in tetrahydrofuran with sodium hydride (NaH).
一系列吡啶并[3,2- e ] [1,4]-二氮杂-2,5-二酮8和吡啶并[2,3- e ] [1,4]二氮杂-2,5-二酮的便捷合成9,是使用α-氨基酸甲基酯衍生物的缩合用1报道ħ -吡啶并[3,2- d ] [1,3]恶嗪-2,4-二酮和1- ħ -吡啶并[2,3- d ] [1,3]恶嗪-2,4-二酮。还通过将α-氨基酸甲酯衍生物与β-氨基酸(2或3)进行肽偶联来合成化合物8和9,然后在四氢呋喃中用氢化钠(NaH)环化。
