the synthesis and biological investigation of three series of novel monocyclic β-lactam derivatives bearing a morpholine ring substituent on the nitrogen. The resulting β-lactam adducts were synthesized via Staudinger's [2 + 2]-ketene-imine cycloaddition reaction. New synthesized products were fully characterized by spectral data and elemental analyses, and then evaluated for anti-inflammatory activity
该研究报道了在氮上带有吗啉环取代基的三系列新型单环β-内酰胺衍生物的合成和生物学研究。通过Staudinger's [2 + 2]-乙烯酮-亚胺环加成反应合成所得的β-内酰胺加成物。通过光谱数据和元素分析充分表征了新合成的产物,然后评估了对人诱导型一氧化氮合酶(iNOS)的抗炎活性和对HepG2细胞系的细胞毒性。化合物3e,3h,3k,5c,5f,6c,6d和6f与参考化合物地塞米松的消炎比值为32相比,抗炎比值分别为38、62、51、72、51、35、55和99时显示出更高的活性。因此,这些化合物可以被认为是有效的iNOS抑制剂。相比之下,它们的IC50值分别为0.48±0.04 mM,0.51±0.01 mM,0.22±0.02 mM,0.12±0.00 mM,0.25±0.05 mM,0.82±0.07 mM,0.44±0.04 mM和0.60±0.04 mM。与阿霉素(IC50 <0
