A series of 4-substituted 2-thiophenesulfonamides was prepared from 3-thiophenecarboxaldehyde using metalation chemistry developed for 3-furaldehyde. Several of these compounds inhibit carbonic anhydrase II in vitro at concentrations of less than 10 nM. In addition, none of these compounds exhibit sensitization

We have synthesized acetal and ketal derivatives of 4'-demethylepipodophyllotoxin-beta-D-glucoside (DMEPG) and epipodophyllotoxin-beta-D-glucoside (EPG) with a number of different aldehydes (viz. acetaldehyde, propionaldehyde, 2-thiophenecarboxaldehyde, 3-thiophenecarboxaldehyde, 2-furancarboxaldehyde, benzaldehyde, phenylacetaldehyde, hydrocinnamaldehyde) and acetone. The cross resistance of these compounds towards a set of

Chicken ovalbumin upstream promoter-transcription factor I (COUP-TFI) is an orphan receptor and member of the nuclear receptor superfamily. Among a series of methylene substituted diindolylmethanes (C-DIMs) containing substituted phenyl and heteroaromatic groups, we identified 1,1-bis(3'-indolyl)-1-(4-pyridyl)-methane (DIM-C-Pyr-4) as an activator of
