  3′,4′-Bis-difluoromethoxycinnamoylanthranilate (FT061): An orally-active antifibrotic agent that reduces albuminuria in a rat model of progressive diabetic nephropathy

  摘要：

  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.

• Synthesis of benzylaminopyrimidines and their fungicidal activities against wheat brown rust and barley powdery mildew

  DOI：10.1002/(sici)1096-9063(1998110)54:3<223::aid-ps814>3.0.co;2-r

  日期：1998.11

  Members of a new class of fungicide containing benzyl-aminopyrimidine as a core structure were synthesized and their fungicidal potencies against wheat brown rust, Puccinia recondita, and barley powdery mildew, Erysiphe graminis, were assessed. Among these fungicides, N-(fluoroalkoxy or fluorophenoxybenzyl)-4-pyrimidinamines showed notable preventive activities. The potency of the new pyrimidines was increased when a difluoromethoxy or tetrafluorophenoxy group was introduced at the 4- or 3-position of the phenyl moiety and a methyl or ethyl group was introduced at the benzyl position. Structure-activity relationships are discussed. (C) 1998 Society of Chemical Industry.
