A novel series of 7beta-[2-(2-amino-5-chloro-thiazol-4-yl)-2(Z)-((S)-1-carboxyethoxyimino)acetamido]cephalosporins bearing various pyridinium groups at the C-3? position were synthesized and their in vitro antibacterial activities against Gram-negative pathogens including Pseudomonas aeruginosa and several Gram-positive pathogens were evaluated. Among the cephalosporins prepared, we found that a cephalosporin bearing the 2-amino-1-(3-methylamino-propyl)-1H-imidazo[4,5-b]pyridinium group at the C-3? position (8a) showed potent and well-balanced antibacterial activities against P. aeruginosa and other Gram-negative pathogens including the strains which produce class C beta-lactamase and extended spectrum beta-lactamase (ESBL). Compound 8a also showed efficacious in vivo activity and high stability against AmpC beta-lactamase. These findings indicate that 2-aminoimidazopyridinium having an aminoalkyl group at the 1-position as a C-3? side chain is suitable for cephalosporins bearing an aminochlorothiazolyl moiety and a carboxyethoxyimino moiety on the C-7 side chain.

Fluorescent tryptophan analogs, like azatryptophan, offer an advantage for exploring protein and peptide structure and dynamics. The chromophoric moieties, azaindole, of the azatryptophan analogs are investigated for their potential as fluorescent probes. The photophysical properties of 4-azaindole (4AI) and 5-azaindole (5AI) and their tautomers are characterized through computational and experimental methods. Both 4AI and 5AI undergo excited state tautomerization in the presence of 1 M NaOH. The protonated forms of 4AI and 5AI have a fluorescence emission of 415 and 410 nm, respectively, while the tautomers of 4AI and 5AI have a fluorescent emission of 480 and 450 nm, respectively. Gas phase computations (B3LYP/6-31+G**) show that the N1H azaindole tautomer is lower in energy in the ground state by as much as 12.5 kcal mol-1, while the N?H azaindole tautomer is lower in energy in the excited state by as much as 18.1 kcal mol-1. Solvent effects on the tautomer energy differences were computed using the isodensity polarized continuum model (IPCM). The polarity of the solvent helps to reduce the energy difference between the tautomers in the ground state by as much as 5.8 kcal mol-1, but not enough to reverse the ground state tautomer preference.

A novel series of C12 vinyl erythromycin derivatives have been discovered which exhibit in vitro and in vivo potency against key respiratory pathogens. The C12 modification involves replacing the natural C 12 methyl group in the erythromycin core with a vinyl group via chemical synthesis. From the C12 vinyl macrolide core, a series of C12 vinyl ketolides was prepared. Several compounds were found to be potent against macrolide-sensitive and -resistant bacteria. The C12 vinyl ketolides 6j and 6k showed a similar antimicrobial spectrum and comparable activity to the commercial ketolide telithromycin. However, the pharmacokinetic profiles of C12 vinyl ketolides 6j and 6k in rats differ from that of telithromycin by having higher lung-to-plasma ratios, larger volumes of distribution, and longer half-lives. These pharmacokinetic differences have a pharmacodynamic effect as both 6j and 6k exhibited better in vivo efficacy than telithromycin in rat lung infection models against Streptococcus pneumoniae and Haemophilus influenzae.

Direct synthesis of N-(hetero)arylated heteroarenes has been realized through Cu-mediated C?N coupling of NH azaheterocycles with aryl C?H bonds under aerobic conditions. This method features a broad scope of both heterocyclic arenes (pyridine, quinoline, pyrazole, imidazole, furan, thiophene, benzofuran, and indole) and NH azaheterocycles (imidazole, pyrazole, indole, azindole, purine, indazole, benzimidazole, pyridone, carbazole), providing a versatile method for the synthesis of pharmaceutically important N-(hetero)arylated heteroarenes. The versatility of this reaction was further demonstrated through late-stage modification of marketed drugs and the synthesis of a key intermediate for accessing a class of angiotensin II receptor 1 antagonists.

7-Methyl-6-azaindole, 7-acetamido-4-azaindole, the substituted 4-amino-, 2-methyl- and 6-methyl-7-azaindole, and the parent 4-, 5-, 6-, and 7-azaindole systems (as anions in dimethylformamide) were alkylated with a variety of primary alkylating agents.The relative importance of charge, product development, and steric approach control in determining the alkylation pattern (pyrrole versus pyridine ring alkylation) are discussed within a framework of variable SN2 transition state structures.Frontier orbital factors appear to be relatively insignificant.The charge distribution, orbitals and energetics of these heterocyclic systems were modelled by ab initio molecular orbital calculations (STO-3G level).Specific association, involving hydrogen bonding between adjacent groups and the alkylating agent, is important in determining the alkylation pattern in some cases.
