reaction intermediate. A diverse array of phosphonates was converted to phosphine oxides using a variety of Grignard reagents for direct carbon–phosphorus functionalization. This new methodology especially simplifies the synthesis of dimethylphosphino (RPMe2)-type phosphines by using air-, water-, and silica-stable intermediates. To highlight this reaction, a new Buchwald-type ligand ([1,1′-biphenyl]-
One possible strategy for modulating autophagy is to disrupt the critical protein–proteininteractions (PPIs) formed during this process. Our attention is on the autophagy-related 12 (ATG12)–autophagy-related 5 (ATG5)–autophagy-related 16-like 1 (ATG16L1) heterotrimer complex, which is responsible for ATG8 translocation from ATG3 to phosphatidylethanolamine. In this work, we discovered a compound with
The present application describes a substituted aryl compound used as an RAD51 inhibitor and a pharmaceutically acceptable salt thereof. The compound has the structure as represented by Formula (I) and has the substituents and structural features as described in the present application. Furthermore, the present application describes a pharmaceutical composition containing the compound as represented by Formula (I) or the pharmaceutically acceptable salt thereof, and the use of the compound as represented by Formula (I) or the pharmaceutically acceptable salt thereof and the pharmaceutical composition containing same in the preparation of a drug for preventing or treating RAD51 mediated diseases.
The disclosure relates to compounds of Formulae (I)-(IX), which are formyl peptide 2 (FPR2) receptor agonists and/or formyl peptide 1 (FPR1) receptor agonists. The disclosure also provides compositions and methods of using the compounds, for example, for the treatment of atherosclerosis, heart failure, chronic obstructive pulmonary disease (COPD), and related diseases.
