Synthesis of new trimethoprim analogs. Antibacterial structure-activity relationship
Calas,Barbier,Giral,et al.
, p. 497 - 504 (2007/10/02)
The authors describe the synthesis of a set of 2,4-diamino 5-(substituted benzyl) pyrmidines analogous of the trimethoprim and estimate the antibacterial activities of these compounds. Some are very specific of Gram + germs. Quantitative structure-activit
