Nitroketene dithioacetal chemistry. Part 2: Synthesis of novel 4-(alkylsulfanyl)-2-[1-nitromethylidene]-1,3-dithioles from the dipotassium salt of 2-nitro-1,1-ethylenedithiol

The reaction of the dipotassium salt of 2-nitro-1,1-ethylenedithiol with long chain alkyl halides in acetonitrile medium furnished the novel heterocyclic, 4-(alkylsulfanyl)-2-[1-nitromethylidene]-1,3-dithioles.

Design, synthesis and biological evaluation of novel inosine 5′-monophosphate dehydrogenase (IMPDH) inhibitors

This study is based on our attempts to further explore the structure-activity relationship (SAR) of VX-148 (3) in an attempt to identify inosine 5′-mono-phosphate dehydrogenase (IMPDH) inhibitors superior to mycophenolic acid. A five-point pharmacophore developed using structurally diverse, known IMPDH inhibitors guided further design of novel analogs of 3. Several conventional as well as novel medicinal chemistry strategies were tried. The combined structure- and ligand-based approaches culminated in a few analogs with either retained or slightly higher potency. The compounds which retained the potency were also checked for their ability to inhibit human peripheral blood mononuclear cells proliferation. This study illuminates the stringent structural requirements and strict SAR for IMPDH II inhibition.

Heterocyclic Sulfonamide Derivatives

The present invention relates to compounds of Formula I where R1a, R1b, X, R2a, R2b, W, R3, R4, and R5 are as defined herein as well as pharmaceutically acceptable salts thereof.
