Abstract
Based on a clinical staged small molecular hClpP activator ONC201, a class of novel hClpP agonists with a [1,8]naphthyridinone scaffold were designed, synthesized and evaluated in a series of biochemical and biological assays. Mechanism studies for the representative compound F20 indicated that it can potently bind to and activate hClpP, efficiently promote the degradation of hClpP substrates, robustly induce ATF4/CHOP regulated integrated stress responses, strongly inhibit cell growth and effectively induce apoptosis in a subset of cancer cell lines. F20 showed good PK profiles when dosed by intravenous injection and exhibited moderate oral bioavailability in mice.
期刊介绍：
Quality research. Outstanding publications. With an impact factor of 3.124 (2019), ChemMedChem is a top journal for research at the interface of chemistry, biology and medicine. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
ChemMedChem publishes primary as well as critical secondary and tertiary information from authors across and for the world. Its mission is to integrate the wide and flourishing field of medicinal and pharmaceutical sciences, ranging from drug design and discovery to drug development and delivery, from molecular modeling to combinatorial chemistry, from target validation to lead generation and ADMET studies. ChemMedChem typically covers topics on small molecules, therapeutic macromolecules, peptides, peptidomimetics, and aptamers, protein-drug conjugates, nucleic acid therapies, and beginning 2017, nanomedicine, particularly 1) targeted nanodelivery, 2) theranostic nanoparticles, and 3) nanodrugs.
