  Synthesis of Imidazo[1,2-a]pyridines as Antiviral Agents

  摘要：

  The synthesis of original imidazo[1,2-a]pyridines bearing a thioether side chain at the 3 position and their antiviral activity are reported. From the synthesized compounds, 4, 15, and 21 were highly active against human cytomegalovirus with a therapeutic index superior to 150. These compounds also showed pronounced activity against varicella-zoster virus. Their structure-activity relationship is discussed.

  hydroxymethylation or methylenation of imidazo-heteroarenes with formaldehyde, generated in situ via the oxidative cleavage of ethylene glycol or glycerol (renewable reagents) through the Malaprade reaction. In the presence of ethylene glycol, a series of 3-hydroxymethyl-imidazo-heteroarenes was obtained in good to excellent yields. These compounds are important intermediates to access pharmaceutical drugs

  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.
