Novel sialidase inhibitors 11 having an α-acylaminoamido group at the C-4 position of Neu5Ac2en 1 against human parainfluenza virus type 1 (hPIV-1) were synthesized using one-pot isocyanide-based four-component condensation, and their inhibitory activities against hPIV-1 sialidase were studied. Compound 11b showed inhibitory activity (IC50=5.1 mM) against hPIV-1 sialidase. The degree of inhibition of 11b was much weaker than that of 1 (IC50=0.3 mM).
采用基于异氰酸酯的四组分缩合法,在 Neu5Ac2en 1 的 C-4 位合成了具有α-酰氨基的新型硅烷化物酶抑制剂 11,并研究了它们对 hPIV-1 硅烷化物酶的抑制活性。化合物 11b 对 hPIV-1 sialidase 具有抑制活性(IC50=5.1 mM)。11b 的抑制程度远远弱于 1(IC50=0.3 mM)。
