Matrix metalloproteinases (MMPs) belong to a family of closely related calcium- and zinc-dependent endopeptidases involved in the degradation and remodeling of extracellular matrix (ECM) proteins that are associated with the tumorigenic processes. MMPs promote tumor invasion and metastasis, regulating host defense mechanisms and normal cell function. Thus,(More)
XK469 is identified as a potent quinoxaline antineoplastic agent based on its significant clinical efficacy. It probably exerts its activity via DNA topoisomerase II (topo II) inhibition. To obtain more effective antineoplastic agents, a spectrum of peptidomimetic-type quinoxaline analogues of XK469 was herein designed, synthesized, and evaluated. Few(More)
As our ongoing work on research of gelatinase inhibitors, an array of hydrazide-containing peptidomimetic derivatives bearing quinoxalinone as well as spiro-heterocyclic backbones were designed, synthesized, and assayed for their in vitro enzymatic inhibitory effects. The results demonstrated that both the quinoxalinone (series I and II) and(More)
