  Synthesis and Antibacterial Activity of 3-Substituted-6-(3-ethyl-4-methylanilino)uracils

  摘要：

  Numerous 3-substituted-6-(3-ethyl-4-methylanilino)uracils (EMAU) have been synthesized and screened for their capacity to inhibit the replication-specific bacterial DNA polymerase IIIC (pol IIIC) and the growth of Gram+ bacteria in culture. Direct alkylation of 2-methoxy-6-amino-4-pyrimidone produced the N3-substituted derivatives, which were separated from the byproduct 4-alkoxy analogues. The N3-substituted derivatives were heated with a mixture of 3-ethyl-4-methylaniline and its hydrochloride to effect displacement of the 6-amino group and simultaneous demethylation of the 2-methoxy group to yield target compounds in good yields. Certain intermediates, e.g. the 3-(iodoalkyl) compounds, were converted to a variety of (3-substituted-alkyl)-EMAUs by displacement. Most compounds were potent competitive inhibitors of pol IIIC (K(i)s 0.02-0.5 mu M), and those with neutral, moderately polar 3-substituents had potent antibacterial activity against Gram+ organisms in culture (MICs 0.125-10 mu g/mL). Several compounds protected mice from lethal intraperitoneal (ip) infections with S. aureus (Smith) when given by the ip route. A water soluble derivative, 3-(4-morpholinylbutyl)-EMAU hydrochloride, given subcutaneously, prolonged the life of infected mice in a dose dependent manner.

  Methods of preparing N3-substituted-4-pyrimidones are disclosed. The methods include combining a 4-pyrimidone and a non-aqueous base, followed by an alkylating agent, for a time sufficient for the pyrimidone and the alkylating agent to react. Methods of preparing an N3-substituted-6-(substituted amino)uracil are also disclosed. The methods include (a) combining an N3-substituted-2-alkoxy-6-amino-4-pyrimidone with an amine compound selected from the group consisting of an amine salt and the corresponding free amine, to form a reaction mixture; and (b) heating the reaction mixture to at least 80° C. for a time sufficient for the N3-substituted-2-alkoxy-6-amino-4-pyrimidone and the amine compound to react to form the final product.
