3,5-Bis(trifluoromethyl)pyrazoles: A Novel Class of NFAT Transcription Factor Regulator
摘要:
A series of bis(trifluoromethyl)pyrazoles (BTPs) has been found to be a novel inhibitor of cytokine production. Identified initially as inhibitors of IL-2 synthesis, the BTPs have been optimized in this regard and even inhibit IL-2 production with a 10-fold enhancement over cyclosporine in an ex vivo assay. Additionally, the BTPs show inhibition of IL-4, IL-5, IL-8, and eotaxin production. Unlike the IL-2 inhibitors, cycloseorine and FK506, the BTPs do not directly inhibit the dephosphorylation of NFAT by calcineurin.

The design, synthesis, and biological evaluation of a series of epothiloneanalogues with novel side chains equipped with an amino group are described. Their design facilitates potential conjugation to selective drug delivery systems such as antibodies. Their synthesis proceeded efficiently via Stille coupling of a readily available vinyl iodide and heterocyclic stannanes. Cytotoxicity studies and
