We explored the properties of corallopyronin A (CorA), a poorly characterized inhibitor of bacterial RNA polymerase (RNAP). It displayed a 50% inhibitory concentration of 0.73 μM against RNAP, compared with 11.5 nM for rifampin. The antibacterial activity of CorA was also inferior to rifampin, and resistant mutants of Staphylococcus aureus were easily selected. The mutations conferring resistan...

The time has come for a global commitment to develop new antibacterial drugs. Current data document the impending disaster due to the confluence of decreasing investment in antibacterial drug research and development concomitant with the documented rapid increase in the level of resistance to currently licensed drugs. Despite the good faith efforts of many individuals, professional societies, a...

Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections.Chitosan polyelectrolyte complex...

The pattern of using antibiotics in community pharmacies in Portharcourt city was investigated with a view of measuring the existing practices in the consumer use of antibacterial drugs. This will serve as a guide to health policy makers to improve rational use of drugs. The parameters investigated are the pattern of sale of antibacterial drugs, pharmacist-patient communication at the point of ...

Purpose: To synthesize and characterize some new gabapentin Schiff base derivatives, to assess their antibacterial, antioxidant antiepileptic activities.Methods: Four derivatives of gabapentin, termed G1, G2, G3 G4, were synthesized by condensation with benzoin, vanillin, acetophenone, benzophenone, respectively. Their chemical identities established FTIR, 1 H NMR 13C techniques. The compounds ...

Cecropin is a cationic antibacterial peptide composed of 35-39 residues. This peptide has been identified as possessing strong antibacterial activity and low toxicity against eukaryotic cells, and it has been claimed that some types of the cecropin family of peptides are capable of killing cancer cells. In this study, the host effect of cloning antibacterial peptide cecropinB2 was investigated....

The development of new antibacterial agents, particularly those with unique biological targets, is essential to keep pace with the inevitable emergence of drug resistance in pathogenic bacteria. We identified the minimal structural component of the cyclic acyldepsipeptide (ADEP) antibiotics that exhibits antibacterial activity. We found that N-acyldifluorophenylalanine fragments function via th...
