Ammonium chloride-catalyzed four-component sonochemical synthesis of novel hexahydroquinolines bearing a sulfonamide moiety

Ammonium chloride as a very inexpensive and readily available reagent efficiently catalyzes one-pot four-component condensation of dimedone with aromatic aldehyde, malononitrile or ethyl cyanoacetate, and sulfonamide derivatives in ethanol at 70°C under ultrasonic irradiation to afford the corresponding 2-amino-4-aryl-1,4,5,6,7,8-hexahydroquinolines bearing a sulfonamide moiety in high yields. In comparison to conventional methods, high yields, easy work-up, and short reaction time are advantages of this sonochemical procedure. The effects of the catalyst, solvent, and temperature are assessed.

In this paper we report the design, synthesis and pharmacological evaluation of a series of N-phenyl-acetamide sulfonamide derivatives (5a-g), planned by structural modification on the prototype paracetamol (1). In this series (5a-g), compound LASSBio-1300 (5e; ID50 = 5.81 μmol/kg) stands out as a new non-hepatotoxic analgesic drug candidate. The increase of area, volume and eletrostatic potential of paracetamol's analogues seems to be beneficial to the analgesic activity. Unlike paracetamol (1) and the other analogues (5a, 5d-g), compounds 5b and 5c presented an important anti-hypernociceptive activity associated to inflammatory pain.
NOVEL ADENOSINE A3 RECEPTOR AGONISTS

Page/Page column 27, (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.
