Formula: C4H5N3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-Aminopyrimidine, is researched, Molecular C4H5N3, CAS is 591-54-8, about Discovery of piperazic acid peptide deformylase inhibitors with in vivo activity for respiratory tract and skin infections. Author is Spletstoser, Jared T.; Dreabit, Jason; Knox, Andrew N.; Benowitz, Andrew; Campobasso, Nino; Ward, Paris; Cui, Guanglei; Lewandowski, Thomas; McCloskey, Lynn; Aubart, Kelly M..
The discovery of a novel series of peptide deformylase inhibitors incorporating a piperazic acid amino acid found in nature is described. These compounds demonstrated potent in vitro enzymic potency and antimicrobial activity. Crystal structure anal. revealed the piperazic acid optimized a key contact with the PDF protein that accounted for the increased enzymic potency of these compounds We describe lead optimization of the P3′ region of the series that resulted in a compound with good potency against three target organisms. One mol. showed in vivo efficacy in a rat respiratory infection model but ultimately did not meet candidate progression criteria.
