Cantharidin and norcantharidin display anticancer activity against a broad range of tumor cell lines. In this study, we have synthesized a series of norcantharidin derivatives and evaluated their cytotoxic effects on four human tumor cell lines together with the genetically normal human diploid fibroblast line WI-38. One of our compounds (1S,4R)-3-((4-(4-(4-fluorophenyl)piperazin-1-ylsulfonyl) phenyl)carbamoyl)-7-oxa-bicyclo[2.2.1]heptane-2-carboxylic acid (12) exhibited potent cytotoxic effects on the tumor cell lines A-549, HepG2, HeLa, and HCT-8, whereas it was less toxic to WI-38 cells than its parent compound, norcantharidin. In addition, this compound inhibited protein phosphatase-1 activity and microtubule formation in HeLa cells, and it also interacts with calf thymus DNA.

We describe a method for the synthesis of sulfonamides through the combination of an organometallic reagent, a sulfur dioxide equivalent, and an aqueous solution of an amine under oxidative conditions (bleach). This simple reaction protocol avoids the need to employ sulfonyl chloride substrates, thus removing the limitation imposed by the commercial availability of these reagents. The resultant method allows access to new chemical space, and is also tolerant of the polar functional groups needed to impart favorable physiochemical properties required for medicinal chemistry and agrochemistry. The developed chemistry is employed in the synthesis of a targeted 70 compound array, prepared using automated methods. The array achieved a 93% success rate for compounds prepared. Calculated molecular weights, lipophilicities, and polar surface areas are presented, demonstrating the utility of the method for delivering sulfonamides with drug-like properties.

Herein we disclose the synthesis and SAR of a series of 4-(phenylsulfamoyl)phenylacetamide compounds as mGlu4 positive allosteric modulators (PAMs) that were identified via a functional HTS. An iterative parallel approach to these compounds culminated in the discovery of VU0364439 (11) which represents the most potent (19.8 nM) mGlu4 PAM reported to date.
NOVEL ADENOSINE A3 RECEPTOR AGONISTS
-
Page/Page column 34, (2008/06/13)
The invention realizes that a series of sulfonamido derivatives with a conserved uronamide group at the 5' position provide superior A3 receptor affinity as well as selectivity. These new adenosine agonists are sulfonamido deritatives N-substituted with aliphatic groups (cyclic or linear) or aromatic radicals.
