Abstract

Cancer cells subvert multiple properties of normal cells, including escaping strict cell cycle regulation, gaining resistance to cell death, and remodeling the tumor microenvironment. The hallmarks of cancer have recently been updated and summarized. Nuclear factor erythroid 2-related factor 1 (NFE2L1, also named NRF1) belongs to the cap'n'collar (CNC) basic-region leucine zipper (bZIP) family. It acts as a transcription factor and is indispensable for maintaining both cellular homoeostasis and organ integrity during development and growth, as well as adaptive responses to pathophysiological stressors. In addition, NFE2L1 mediates the proteasome bounce-back effect in the clinical proteasome inhibitor therapy of neuroblastoma, multiple myeloma, and triple-negative breast cancer, which quickly induces proteasome inhibitor resistance. Recent studies have shown that NFE2L1 mediates cell proliferation and metabolic reprogramming in various cancer cell lines. We combined the framework provided by "hallmarks of cancer" with recent research on NFE2L1 to summarize the role and mechanism of NFE2L1 in cancer. These ongoing efforts aim to contribute to the development of potential novel cancer therapies that target the NFE2L1 pathway and its activity. [ABSTRACT FROM AUTHOR]

Abstract

Phosphine‐catalyzed chemodivergent reactions of para‐quinone methides (p‐QMs) affording a wide variety of diarylmethyl thioether derivatives have been reported. In the transformation presented in this work, P(4‐FC6H4)3 catalyzed the direct 1,6‐addition of p‐QMs with thiols, whereas P(4‐MeC6H4)3 promoted the tandem addition/self‐aldol condensation reactions of p‐QMs with 1,4‐dithiane‐2,5‐diol. Moreover, some of the obtained products were screened against cancer cell lines HepG2, NB4, and K562, and one was found to inhibit the proliferation of all the tested cancer cell types.
