Rational design of 6-(2,4-diaminopyrimidinyl)-1,4-benzoxazin-3-ones as small molecule renin inhibitors.
N.A.Powell, F.L.Ciske, C.Cai, D.D.Holsworth, K.Mennen, C.A.Van Huis, M.Jalaie, J.Day, M.Mastronardi, P.McConnell, I.Mochalkin, E.Zhang, M.J.Ryan, J.Bryant, W.Collard, S.Ferreira, C.Gu, R.Collins, J.J.Edmunds.
We report the design and synthesis of a series of 6-(2,4-diaminopyrimidinyl)-1,4-benzoxazin-3-ones as orally bioavailable small molecule inhibitors of renin. Compounds with a 2-methyl-2-aryl substitution pattern exhibit potent renin inhibition and good permeability, solubility, and metabolic stability. Oral bioavailability was found to be dependent on metabolic clearance and cellular permeability, and was optimized through modulation of the sidechain that binds in the S3(sp) subsite.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
