Cinnamoylanthranilates including tranilast have been identified as promising antifibrotics that can reduce fibrosis occurring in the kidney during diabetes, thereby delaying and/or preventing kidney dysfunction. Structure-activity relationships aimed at improving potency and metabolic stability have led to the discovery of FT061. This compound, which bears a bis-difluoromethoxy catechol, attenuates TGF-beta-stimulated production of collagen in cultured renal mesangial cells (approx 50% at 3 mu M). When dosed orally at 20 mg/kg to male Sprague Dawley rats, FT061 exhibited a high bioavailability (73%), C-max of 200 mu M and T-max of 150 min, and a half-life of 5.4 h. FT061 reduced albuminuria when orally dosed in rats at 200 mg kg/day in a late intervention study of a rat model of progressive diabetic nephropathy. (C) 2013 Elsevier Ltd. All rights reserved.
