A new two-step procedure for functionalized-3(2H)-pyridazinones through homolytic substitution of 3-chloropyridazines

The homolytic substitution of protonated 3-chloro-6-methylpyridazine 1a, followed by hydrolysis with AcOH affords 4- or 4,5-functionalized pyridazinones 3a-c. Less reactivity is found for 3-chloro-6-phenylpyridazine 1b. Hypotheses about these different behaviour patterns are proposed and discussed.

Development of a novel therapeutic suppressor of brain proinflammatory cytokine up-regulation that attenuates synaptic dysfunction and behavioral deficits

We report the development of a novel, aqueous-soluble, safe, small molecule, experimental therapeutic that suppresses injury-induced, proinflammatory cytokine increases in the brain, with resultant attenuation of synaptic protein biomarker loss and improvement in hippocampus-dependent behavioral deficits. A GMP production scheme for the active pharmaceutical ingredient, compound 17, is presented. The development and large-scale availability of this novel compound allow exploration of new, potentially disease-modifying, therapeutic approaches to CNS disorders.
