Considering phenols and coumarins as lead molecules for obtaining non-sulfonamide inhibitors of carbonic anhydrases (CAs, EC 4.2.1.1), we screened a large number of compounds possessing diverse chemotypes, but structural features which resemble the two chemical classes. Here we report an

A series of coumarins incorporating tert-butyl-dimethylsilyloxy- or allyoxy- moieties in positions 4-, 6 or 7 of the heterocyclic ring have been synthesized and then converted to the corresponding 2-thioxo-coumarins. Other derivatives incorporating hydroxyethyloxy-, tosylethoxy- and 2-fluroethyloxy- moieties in position 7

Two series of disubstituted coumarins incorporating ether and acetyl/propionyl moieties in positions 6,7- and 7,8- of the heterocyclic ring were synthesized investigated for the inhibition of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). All these coumarins were very weak

To report the results of the Dutch randomized trial comparing standard catheter-directed and ultrasound-accelerated thrombolysis (UST) for the treatment of arterial thromboembolic occlusions. The DUET study ( controlled-trials.com ; identifier ISRCTN72676102) was designed to assess whether UST can reduce therapy
