摘要:
Isoxazolecarboxamide derivatives (I) (R=alkyl, alkoxy, polyfluoroalkoxy, OH or CF3SO2O; each of R1 and R2 independently =H, halogen, polyfluoroalkoxy or alkoxy; R3 = one or more substituents selected from H, halogen, alkyl, alkoxy, NO2, NH2, NHacyl, CN, alkoxycarbonyl, carboxamido; R4 = H, alkyl or aralkyl; an n is 0, 1 or 2) and their N-oxides and pharmaceutically acceptable salts are endowed with adrenergic antagonist activity and high selectivity toward the αla adrenergic receptor with respect to the 5-HTlA receptor. This activity profile suggests the use of these derivatives in the treatment of obstructive syndromes of the lower urinary tract, including BPH, without side effects associated with hypotensive activity being present.

Benzopyran derivatives (I) (R = phenyl, alkoxycarbonyl, alkylcarbonyl, CONH2, CONH(alkyl), CON(alkyl)2, CN or alkoxycarbonylamino; R2 = alkyl, alkoxy, polyfluoroalkoxy, OH or CF3SO2O; each of R4 and R5 independently = H, halogen, polyfluoroalkyl, polyfluoroalkoxy, CN or CONH2; n is 0, 1 or 2; but if R = Ph and both of R4 and R5 = H or hologen atoms, then R2 = polyfluoroalkoxy or CF3SO2O) and their N-oxides and pharmaceutically acceptable salts are endowed with adrenergic antagonist activity and, in particular, with high selectivity for the α1-adrenergic receptor as compared to the 5-HT1A receptor. This activity profile suggests the use of these benzopyran derivatives in the treatment of obstructive syndromes of the lower urinary tract, including BPH, without side-effects associated with hypotensive activity.

摘要:
Compounds (I) (R = aryl, cycloalkyl or polyhaloalkyl, R1 = alkyl, alkoxy, polyfluoroalkoxy, hydroxy or trifluoromethanesulphonyloxy, each of R2 and R3 independently = H, halogen, alkoxy or polyfluoroalkoxy, n is 0, 1 or 2) and their N-oxides or pharmaceutically acceptable salts are endowed with enhanced selectivity for the α1 adrenergic receptor and a low activity in lowering blood pressure. This activity profile makes these compounds useful in the treatment of obstructive syndromes of the lower urinary tract, including benign prostatic hyperplasia (BPH), in lowering intraocular pressure, in the treatment of cardiac arrhythmia and erectile and sexual dysfunction, and in the treatment of lower urinary tract symptoms (LUTS) and neurogenic lower urinary tract dysfunction (NLUTD). Compounds (I) per se, pharmaceutical compositions containing compounds (I) and medical uses of compounds (I) are claimed.
摘要:
There are disclosed compounds of general formula (I). Y is a linking group, chosen from a wide range, but including -COO-, -CH2COO-, -CONH-, -CON(CH3)-, -CH2CONH-, -SO2NH-, -SO2N(CH3)- and -PO(OC2H5)NH-. W is an alkylene chain. A is a substituted phenyl group or a benzofuran or benzodioxan group. R and R1 may have many values, but R is preferably a bulky group. These compounds and their prodrugs, enantiomers, diastereoisomers, N-oxides and pharmaceutically acceptable salts block α1A-adrenergic receptors and are thus useful for the prevention of contractions of the prostate, urethra and lower urinary tract, without affecting blood pressure.

Compounds (I) (R 1 is an optionally substituted C 1 -C 13 heteromonocyclic, heterobicyclic or heterotri cyclic group containing from 1 to 5 heteroatoms selected from N, O and S; R 2 is H, an optionally substituted monocyclic aromatic group, or a C 1 -C 5 heteroaromatic group containing from 1 to 4 heteroatoms selected from N, O and S; R 3 is an optionally substituted C 1 -C 13 heteromonocyclic, heterobicyclic or heterotri cyclic group containing from 1 to 5 heteroatoms selected from N, O and S; an optionally substituted mono-, bi- or tricyclic C 6 -C 14 aryl group, an optionally substituted C 3 -C 6 cycloalkyl group, or an optionally substituted C 3 -C 6 cycloalkenyl group; each R 4 , independently for each position capable of substitution, is H or C 1 -C 6 alkyl; R 5 is H, halogen or C 1 -C 6 alkyl; m is 0, 1 or 2; n is 0, 1 or 2; p is 0, 1, 2, 3, 4, 5, or 6; and --- is an optional double bond) and their enantiomers, diastereomers, N-oxides and pharmaceutically acceptable salts, and pharmaceutical compositions containing them, are useful for the treatment of neuromuscular dysfunction of the lower urinary tract and also for the treatment of gastrooesophageal reflux disease; anxiety disorder; abuse, substance dependence and substance withdrawal disorders; neuropathic pain disorder, migraine and fragile X syndrome disorders.
摘要:
The administration to a mammal of a combination of compounds, at least one of which is an α2δ calcium channel subunit (A2d) ligand and at least one of which is a non-steroidal anti-inflammatory drug (NSAID), provides a surprising and potent inhibition of the micturition reflex, superior to that obtained by treatment with an A2d ligand or NSAID alone. Combinations of A2d ligand and NSAIDs are thus useful for treatment of lower urinary tract disorders and symptoms thereof. Preferred A2d ligands are gabapentin and pregabalin. Preferred NSAIDs are celecoxib, diclofenac, diflunisal, flurbiprofen, naproxen, nimesulide or sulindac.

Further uses include the treatment of migraine; gastroesophageal reflux disease (GERD); anxiety disorder; abuse, substance dependence and substance withdrawal disorder; neuropathic pain disorder; and fragile X syndrome disorders.
