Abstract:
A straightforward and efficient methodology has been developed for the synthesis of 3-cyano-2-pyridones via the C–C and C–N bond formation processes. A total of 51 diverse 3-cyano-2-pyridone derivatives were obtained in moderate to excellent yields. This reaction featured advantages such as a metal-free process, wide functional group tolerance, simple operation, and mild conditions. A plausible mechanism for the reaction was proposed. 3-cyano-2-pyridones as ricinine analogues for insecticidal properties were evaluated, and the compound 3ci (LC50 = 2.206 mg/mL) showed the best insecticidal prop

Abstract:
The Caf1/CNOT7 nuclease is a catalytic component of the Ccr4-Not deadenylase complex, which is a key regulator of post-transcriptional gene regulation. In addition to providing catalytic activity, Caf1/CNOT7 and its paralogue Caf1/CNOT8 also contribute a structural function by mediating interactions between the large, non-catalytic subunit CNOT1, which forms the backbone of the Ccr4-Not complex and the second nuclease subunit Ccr4 (CNOT6/CNOT6L). To facilitate investigations into the role of Caf1/CNOT7 in gene regulation, we aimed to discover and develop non-nucleoside inhibitors of the enzyme

Abstract:
ABSTRACTHIV-1 maturation inhibitors are a novel class of antiretroviral compounds that consist of two structurally distinct chemical classes: betulinic acid derivatives and the pyridone-based compound PF-46396. It is currently believed that both classes act by similar modes of action to generate aberrant noninfectious particles via inhibition of CA-SP1 cleavage during Gag proteolytic processing. In this study, we utilized a series of novel analogues with decreasing similarity to PF-46396 to determine the chemical groups within PF-46396 that contribute to antiviral activity, Gag binding, and th

Glycogen Phosphorylase (GP) is the regulatory enzyme that catalyses the first step in glycogen degradation and is a potential enzyme target for therapeutic intervention in the treatment of diabetes. The 16 amino acid C-terminal sequence of human Gl is the only known targeting subunit that binds to GPa. Blocking the interactions between Gl and GPa should reduce high blood glucose levels in a diabetic person. A segment of the 16 amino acid segment was chosen for a small molecule peptidomimetric approach, and de nova design from this segment identified the pyridone ring as apotential scaffold. Th

An introduction to the use of oligonucleotides as antigene or antisense therapeutic agents is presented. This includes an analysis of the major areas of structural change implemented to improve the stability, specificity, nuclease resistance and cellular delivery of oligonucleotides. The synthetic aspect of the project concerns the preparation of two novel 'pyridinestretched' heterocyclic bases principally designed to improve base stacking.

Abstract:
The chemistry of pyridine and its derivatives is of considerable importance in the synthesis of intermediates leading to biologically active compounds and novel materials. Generally, derivatives of pyridine are stable and relatively unreactive but can be attacked by electrophiles at ring nitrogen and certain carbon atoms. Pyridines undergo radical substitution reactions preferentially at the 2-position. Simple pyridines and their benzo derivatives are weak bases that form salts with strong acids. Various Lewis acids form complexes with pyridine and its benzo derivatives. The quaternization of

The impetus for research in this area comes from the enormous number of plant-derived natural products based on the benzopyrilium, coumarin, and chromone structures.
