Abstract

NEDD8 activating enzyme (NAE) plays an important role in regulating intracellular proteins with key parts in a broad array of cellular functions. On the basis of previously work, a series of 2H-chromen-2-one based NAE inhibitors were designed and synthesized. Through enzyme-based and cell-based assays, LP0040 was identified as a non-nucleoside NAE/UAE dual inhibitor. It could inhibit NAE/UAE activities and downregulated degradations of related substrates in AGS cells, promoting apoptosis in low micromole concentrations. LP0040 possessed anti-proliferation activities with IC50 values of 0.76-3.29 μM against multiple human cancer lines and had synergistic effect with bortezomib. Thus LP0040 represented valuable starting points for future development of NAE/UAE dual inhibitors.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
