• Synthesis and ocular effects of imidazole nitrolic acid and amidoxime esters

  Esters of 1-(H)-imidazole-5-nitrolic acid and 1-methyl-imidazole-5-carboxamide oxime were prepared to study the effect of esterification on the ocular effects of these compounds. Esterifications were performed with acid chloride. Acid chloride also reacts with the ring nitrogen of 1-(H)-imidazole-5-nitrolic acid, but the desired esters could be selectively prepared by adjustment of the reaction conditions. Esterification led to loss of the ocular effects exhibited by the parent compounds. (C) 2006 Elsevier Ltd. All rights reserved.

  Novel 1-R-imidazole-5-amidoximes and I-R-5-cyano-imidazole-4-amidoximes (R: H, Me, Bn) were prepared from their corresponding nitriles and were tested for their efficacy to lower intraocular pressure (IOP) in rabbits. The ability of these compounds to donate nitric oxide (NO) was studied by observing the stimulation of formation of cyclic guanosine-3',5'-monophosphate (cGMP) in the incubation of porcine iris-ciliary body. In the incubation experiments, 1-methylimidazole-5-amidoxime and 1(H)-imidazole-4(5)-amidoxime stimulated formation of cGMP indicating NO donating ability of these compounds. 1-Methylimidazole-5-amidoxime lowered IOP significantly after intravitreal injection.

  One-pot synthesis of 3,5-disubstituted 1,2,4-oxadiazoles from carboxylic acids and nitriles was optimized to parallel chemistry. The method was validated on a 141 member library; the desired products were recovered with a high success rate and in moderate yields. Practical application of the approach was demonstrated in the synthesis of bioactive compound pifexole and agonists of free fatty acid receptor
