Compounds of formulae (IA) and (IB) or pharmaceutically or veterinarily acceptable salts thereof, or pharmaceutically or veterinarily acceptable solvates of either entity, wherein R1 is C1 to C3 alkyl substituted with C3 to C6 cycloalkyl, CONR5R6 or a N-linked heterocyclic group; (CH2)nHet or (CH2)nAr; R2 is C1 to C6 alkyl; R3 is C1 to C6 alkyl optionally substituted with C1 to C4 alkoxy; R4 is SO2NR7R8; R5 and R6 are each independently selected from H and C1 to C4 alkyl optionally substituted with C1 to C4 alkoxy, or, together with the nitrogen atom to which they are attached, form a 5- or 6-membered heterocyclic group; R7 and R8, together with the nitrogen atom to which they are attached, form a 4-R10-piperazinyl group; R10 is H or C1 to C4 alkyl optionally substituted with OH, C1 to C4 alkoxy or CONH2; H is an optionally substituted C-linked 5- or 6-membered heterocyclic group; Ar is optionally substituted phenyl; and n is 0 or 1; are potent and selective cGMP PDE5 inhibitors useful in the treatment of, inter alia, male erectile dysfunction and female sexual dysfunction.
Synthesis and Physicochemical Studies on 1,2-Bisazolylethanes
Torres, J.,Lavandera, J. L.,Cabildo, P.,Claramunt, R. M.,Elguero, J.
, p. 771 - 782 (2007/10/02)
Twenty symmetrical and asymmetrical 1,2-bisazolylethanes have been obtained from azoles and 1,2-dibromoethane or 1-chloro-2-(pyrazol-1-yl)ethane by phase transfer catalysis (PTC).The 1H and 13C nmr properties are reported and the chemical shifts of the ethylene carbon atoms discussed using an additive model.
