Pantothenate kinase (PANK) is the critical regulator of intracellular levels of CoA and has emerged as an attractive target for treating neurol. and metabolic disorders. This report describes the optimization, synthesis, and full structure-activity relationships of a new chem. series of pantothenate competitive PANK inhibitors. Potent drug-like mols. were obtained by optimizing a high throughput screening hit, using lipophilic ligand efficiency (LipE) derived from human PANK3 IC50 values to guide ligand development. X-ray crystal structures of PANK3 with index inhibitors from the optimization were determined to rationalize the emerging structure activity relationships. The anal. revealed a key bidentate hydrogen bonding interaction between pyridazine and R306′ as a major contributor to the LipE gain observed in the optimization. A tractable series of PANK3 modulators with nanomolar potency, excellent LipE values, desirable physicochem. properties, and a well-defined structural binding mode was produced from this study. In the experiment, the researchers used many compounds, for example, 3,6-Dichloropyridazine (cas: 141-30-0Recommanded Product: 3,6-Dichloropyridazine).
3,6-Dichloropyridazine (cas: 141-30-0) belongs to pyridazine derivatives. Pyridazines are rare in nature, possibly reflecting the scarcity of naturally occurring hydrazines, common building blocks for the synthesis of these heterocycles. The activity depends upon the changes of substituted groups in the pyridazine ring system resulting in different biological activities. In addition, the natural pyrimidine bases uracil, thymine, and cytosine, which are constituents of the nucleic acids, are found to be the most important naturally occurring diazines.Recommanded Product: 3,6-Dichloropyridazine
