2,4-Diamino-5-benzylpyrimidines and analogs as antibacterial agents. 9. Lipophilic trimethoprim analogs as antigonococcal agents
摘要:
Lipophilic analogues of trimethoprim (1) bearing 3,5-dialkyl-4-hydroxy substituents in the benzene ring are much more active in vitro against Neisseria gonorrhoeae than is 1. The 3,5-diisopropyl-4-hydroxy derivative (2) was selected as a candidate for clinical evaluation as an antigonococcal agent, and as part of the preliminary evaluation it was submitted to extended pharmacokinetic and metabolism studies in dogs. Although the compound was not extensively conjugated by metabolic enzymes, one of the methyl groups was metabolized to produce a 3-isopropyl-4-hydroxy-5-(alpha-carboxyethyl)benzyl derivative (43), which was rapidly excreted. Related analogues were likewise extensively metabolized.

Pharmaceutical compositions containing 2,4-diamino-5-(3. 5-dialkyl-4-hydroxybenzyl) pyrimidines wherein the alkyl groups contain from 2 to 4 carbon atoms are useful in the treatment of bacterial infections. The first medical use of such compounds, novel chemical compounds wherein the alkyl groups are propyl or butyl, except the di-i-propyl compound, a process for preparing the novel compounds and chemical intermediates used in their preparation are also disclosed.
