  QSAR study for a novel series of ortho disubstituted phenoxy analogues of α1-adrenoceptor antagonist WB4101

  摘要：

  On the basis of the affinities at the alpha(1a)-, alpha(1b)- and alpha(1d)-adrenoceptors and the 5-HT1A receptor of a previous series of sixteen 2-[(2-phenoxyethyl)aminomethyl]-1,4-benzodioxanes ortho monosubstituted at the phenoxy moiety, a number of ortho disubstituted analogues were designed, synthesized in both the enantiomeric forms and tested in binding assays on the same receptors. The affinity values of the new compounds 1-11 were compared with those of the enantiomers of the 2,6-dimethoxyphenoxy analogue, the well-known alpha 1 antagonist WB4101, and of the ortho monosubstituted derivatives, suggesting some distinctive aspects of the interaction of the phenoxy moiety, in particular with the alpha 1a-AR and the 5-HT1A receptor, of the monosubstituted and the disubstituted compounds. A classical quantitative structure-activity relationship (Hansch) analysis was applied to the whole set of the S enantiomers of the ortho mono- and disubstituted WB4101 analogues (26 compounds), finding a very good correlation for the a,, affinity. For this latter, a significant parabolic relationship was also found with the volume of the two ortho substituents. Diametrically opposite, the same relationships for the 5-HT1A exhibit low or insignificant correlation coefficients. (c) 2006 Elsevier SAS. All rights reserved.

  We previously reported the identification of (2S)-((2-benzoylphenyl)amino)-3-4-[2-(5-methyl-2-phenyloxazol-4-yl)ethoxy]phenyl}propanoic (2) (PPAR gamma pK(i) = 8.94, PPAR gamma, pEC(50) = 9.47) as a potent and selective PPAR gamma agonist. We now report the expanded structure-activity relationship around the phenyl alkyl ether moiety by pursuing both a classical medicinal chemistry approach and a solid-phase chemistry approach for analogue synthesis. The solution-phase strategy focused on evaluating the effects of oxazole and phenyl ring replacements of the 2-(5-methyl-2-phenyloxazol-4-yl)ethyl side chain of 2 with several replacements providing potent and selective PPAR gamma agonists with improved aqueous solubility. Specifically, replacement of the phenyl ring of the phenyloxazole moiety with a 4-pyridyl group to give 2(S)-((2-benzoylphenyl)amino)-3-4-[2-(5-methyl-2-pyridin-4-yloxazol-4-yl)ethoxy]phenyl}propionic acid (16) (PPAR gamma pK(i) = 8.85, PPAR gamma pEC(50) = 8.74) or a 4-methylpiperazine to give 2(S)-((2-benzoylphenyl)amino)-3-(4-2-[5-methyl-2-(4-methylpiperazin-1-yl)thiazol-4-yl]ethoxy}pheynyl)propionic acid (24) (PPAR gamma pK(i) = 8.6, PPAR gamma pEC(50) = 8.89) provided two potent and selective PPAR gamma agonists with increased solubility in pH 7.4 phosphate buffer and simulated gastric fluid as compared to 2. The second strategy took advantage of the speed and ease of parallel solid-phase analogue synthesis to generate a more diverse set of phenyl alkyl ethers which led to the identification of a number of novel, high-affinity PPAR gamma ligands (PPAR gamma pK(i)'s 6.98-8.03). The combined structure-activity data derived from the two strategies provide valuable insight on the requirements for PPAR gamma binding, functional activity, selectivity, and aqueous solubility.
