A renal flow system and method direct fluid into renal arteries from a location within the aorta. A renal flow assembly has a tapered tube that is adjustable between a radially collapsed condition for delivery to the location through a delivery sheath and a radially expanded condition that divides aortic flow into exterior and interior paths. The tube's wall is made from a sheet of flexible material, such as PTFE or ePTFE. Two, nickel-titanium rings radially support the tube's ends and are connected by a longitudinal spine support. A fluid delivery assembly injects drug to flow along the exterior flow path and the tubular wall directs the agent into the renal artery ostium. The tube's taper has localized shape for circumferential agent mixing to infuse both kidneys' renals. The flow assembly allows an interventional device, e.g. delivery catheter, to advance across the location while directing blood into the renals and perfusing downstream circulation. The renal flow assembly and distal device are used within a common guide sheath through a single puncture wound. Vasodilators, antioxidants, or diuretics are delivered to the kidneys to treat / prevent RCN, CHF, or ARF.

This invention provides novel compounds according to general formula (1) wherein A is a bicyclic or tricyclic azepine derivative, V1 and V2 are both H, OMe or F, or one of V1 and V2 is Br, Cl, F, OH, OMe, OBn, OPh, O-acyl, N3, NH2, NHBn or NH-acyl and the other is H, or V1 and V2 together are ═O, —O(CH2)pO— or —S(CH2)pS—; W1 is either O or S; X1 and X2 are both H, or together are ═O or ═S; Y is OR5 or NR6R7; R1, R2, R3 and R4 are independently selected from H, lower alkyl, lower alkyloxy, F, Cl and Br; R5 is selected from H and lower alkyl; R6 and R7 are independently selected from H and lower alkyl, or together are —(CH2)n—; n=3, 4, 5, 6; and p is 2 or 3. The compounds are agonists at the vasopressin V2 receptor and are useful as antidiuretics and procoagulants. The invention further comprises pharmaceutical compositions incorporating these vasopressin agonists, which compositions are particularly useful in the treatment of central diabetes insipidus, nocturnal enuresis and nocturia.

The sulfonamide or carboamide derivatives of the formula (I) and a pharmaceutical composition which comprise them as an active ingredient: (wherein A ring, B ring is carbocyclic ring, heterocyclic ring; Z1 is -COR1, -CH=CH-COR1 etc.; Z2 is H, alkyl etc.; Z3 is single bond, alkylene; Z4 is SO2, CO; Z5 is alkyl, phenyl, heterocyclic ring etc.; R2 is CONR8, O, S, NZ6, Z7-alkylene, alkylene etc.; R3 is H, alkyl, halogen, CF3 etc.; R4 is H, (substituted) alkyl etc.; n, t is 1-4). The compounds of the formula (I) can bind to receptors of PGE2 and show antagonistic activity against the action thereof or agonistic activity. Therefore, they are considered to be useful as medicine for inhibition of uterine contraction, analgesics, antidiarrheals, sleep inducers, medicine for increase of vesical capacity or medicine for uterine contraction, cathartic, suppression of gastric acid secretion, antihypertensive or diuretic agents.

The invention describes novel compositions and kits comprising at least one nitric oxide enhancing diuretic compound, or pharmaceutically acceptable salts thereof, and, optionally, at least one nitric oxide enhancing compound and / or at least one therapeutic agent. The invention also provides methods for (a) treating conditions resulting from excessive water and / or electrolyte retention; (b) treating cardiovascular diseases; (c) treating renovascular diseases; (d) treating diabetes; (e) treating diseases resulting from oxidative stress; (f) treating endothelial dysfunctions; (g) treating diseases caused by endothelial dysfunctions; (h) treating cirrhosis; (j) treating pre-eclampsia; (k) treating osteoporosis; (l) treating nephropathy; (m) treating peripheral vascular diseases; (n) treating portal hypertension; (o) treating central nervous system disorders; (p) treating metabolic syndrome; (q) treating sexual dysfunctions; and (r) hyperlipidemia. The nitric oxide enhancing diuretic compounds comprise at least one nitric oxide enhancing group linked to the diuretic compound through one or more sites such as carbon, oxygen and / or nitrogen via a bond or moiety that cannot be hydrolyzed.
