LipE guided discovery of isopropylphenyl pyridazines as pantothenate kinase modulators

Pantothenate kinase (PANK) is the critical regulator of intracellular levels of coenzyme A and has emerged as an attractive target for treating neurological and metabolic disorders. This report describes the optimization, synthesis, and full structure–activity relationships of a new chemical series of pantothenate competitive PANK inhibitors. Potent drug-like molecules 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 analysis 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 physicochemical properties, and a well-defined structural binding mode was produced from this study.

Orally active 7-substituted (4-benzylphthalazin-1-yl)-2-methylpiperazin-1- yl]nicotinonitriles as active-site inhibitors of sphingosine 1-phosphate lyase for the treatment of multiple sclerosis

Sphingosine 1-phosphate (S1P) lyase has recently been implicated as a therapeutic target for the treatment of multiple sclerosis (MS), based on studies in a genetic mouse model. Potent active site directed inhibitors of the enzyme are not known so far. Here we describe the discovery of (4-benzylphthalazin-1-yl)-2-methylpiperazin-1-yl]nicotinonitrile 5 in a high-throughput screen using a biochemical assay, and its further optimization. This class of compounds was found to inhibit catalytic activity of S1PL by binding to the active site of the enzyme, as seen in the cocrystal structure of derivative 31 with the homodimeric human S1P lyase. 31 induces profound reduction of peripheral T cell numbers after oral dosage and confers pronounced protection in a rat model of multiple sclerosis. In conclusion, this novel class of direct S1P lyase inhibitors provides excellent tools to further explore the therapeutic potential of T cell-targeted therapies in multiple sclerosis and other autoimmune and inflammatory diseases.

An expedient Pd/DBU mediated cyanation of aryl/heteroaryl bromides with K4[Fe(CN)6]

A practical Pd(PPh3)4/DBU catalytic system for the synthesis of pharmaceutically relevant aminopyridine nitrile intermediates, as well as a variety of other aryl nitriles using non-toxic K4[Fe(CN) 6] has been developed. The key features of our new protocol for cyanation lie in that the reaction can be carried out with readily available Pd(PPh3)4 under mild and green conditions, even without the assistance of other ligands.
