Synthesis of functionalized pyridazin-3(2 H)-ones via nucleophilic substitution of hydrogen (SNH)

Reaction of 2-benzyl-5-halopyridazin-3(2H)-ones (3) with Grignard reagents followed by quenching with electrophiles unexpectedly yielded 4,5-disubstituted pyridazin-3(2H)-ones instead of 5-substituted pyridazin-3(2H)-ones. These reactions represent the first examples of cine substitution in which the anionic sigmaH-adduct is quenched by electrophiles (other than a proton) before elimination takes place. Insight into the reaction mechanism led to the direct transformation of 2-benzylpyridazin-3(2H)-one (7) and 2-benzyl-6-chloropyridazin-3(2H)-one (9) into the corresponding C-4 alkyl and aryl derivatives (when Br2 was used as the electrophile).

The discovery of benzoxazine sulfonamide inhibitors of NaV1.7: Tools that bridge efficacy and target engagement

The voltage-gated sodium channel NaV1.7 has received much attention from the scientific community due to compelling human genetic data linking gain- and loss-of-function mutations to pain phenotypes. Despite this genetic validation of NaV1.7 as a target for pain, high quality pharmacological tools facilitate further understanding of target biology, establishment of target coverage requirements and subsequent progression into the clinic. Within the sulfonamide class of inhibitors, reduced potency on rat NaV1.7 versus human NaV1.7 was observed, rendering in vivo rat pharmacology studies challenging. Herein, we report the discovery and optimization of novel benzoxazine sulfonamide inhibitors of human, rat and mouse NaV1.7 which enabled pharmacological assessment in traditional behavioral rodent models of pain and in turn, established a connection between formalin-induced pain and histamine-induced pruritus in mice. The latter represents a simple and efficient means of measuring target engagement.

Use of small-molecule crystal structures to address solubility in a novel series of g protein coupled receptor 119 agonists: Optimization of a lead and in vivo evaluation

G protein coupled receptor 119 (GPR119) is viewed as an attractive target for the treatment of type 2 diabetes and other elements of the metabolic syndrome. During a program toward discovering agonists of GPR119, we herein describe optimization of an initial lead compound, 2, into a development candidate, 42. A key challenge in this program of work was the insolubility of the lead compound. Small-molecule crystallography was utilized to understand the intermolecular interactions in the solid state and resulted in a switch from an aryl sulphone to a 3-cyanopyridyl motif. The compound was shown to be effective in wild-type but not knockout animals, confirming that the biological effects were due to GPR119 agonism.

Design, synthesis, and antidiabetic activity of 4-phenoxynicotinamide and 4-phenoxypyrimidine-5-carboxamide derivatives as potent and orally efficacious TGR5 agonists

4-Phenoxynicotinamide and 4-phenoxypyrimidine-5-carboxamide derivatives as potent and orally efficacious TGR5 agonists are reported. Several 4-phenoxynicotinamide derivatives were found to activate human and mouse TGR5 (hTGR5 and mTGR5) with EC50 values in the low nanomolar range. Compound 23g, with an EC50 value of 0.72 nM on hTGR5 and an EC 50 value of 6.2 nM on mTGR5, was selected for further in vivo efficacy studies. This compound exhibited a significant dose-dependent glucagon-like peptide-1 (GLP-1) secretion effect. A single oral dose of 23g (50 mg/kg) significantly reduced blood glucose levels in db/db mice and caused a 49% reduction in the area under the blood glucose curve (AUC)0-120min following an oral glucose tolerance test (OGTT) in imprinting control region (ICR) mice. However, 23g stimulated gallbladder filling, which might result in side effects to the gallbladder.

Chiral imidazole derivatives synthesis from enantiopure N-protected alpha-amino acids

A route to the preparation of enantiopure ligands based on a 2-phenylimidazol ring is described. The stereogenic centre is placed into the chain bonded to the fourth carbon of the imidazole ring. The synthesis starts from inexpensive and readily available N-protected alpha-amino acids, as the source of chirality, which are converted into appropriate alpha-diazoketones and, consequently, into alpha-bromoketones. These alpha-bromoketones are good precursors for reactions with amidines to provide the imidazole ring. The deprotection into the final products was carried out using hydrogen.
