The pharmacokinetics of the quinolone enoxacin were studied after a 600-mg oral dose was given to each of six male volunteers. The levels of the compound were measured in serum, blister fluid, and urine. Absorption was variable, with peak levels (mean, 3.7 micrograms/ml) being attained between 0.75 and 3.0 h (mean, 1.9 h). The serum elimination half-life was 6.2 h, and 71.6% of the drug was rec...
Certain pathogenic bacteria produce and release toxic peptides to ensure either nutrient availability or evasion from the immune system. These peptides are also toxic to the producing bacteria that utilize dedicated ABC transporters to provide self-immunity. The ABC transporter McjD exports the antibacterial peptide MccJ25 in Escherichia coli Our previously determined McjD structure provided so...
Peptides are part of the host defense system against bacteria and fungi in species right across the evolutionary scale. However, endogenous antibacterial peptides are often composed of 25 residues or more and, therefore, are not ideal for therapeutic use. Hence it is of considerable interest to design and engineer short peptides having antimicrobial activity. Peptides composed of 18 amino acids...
Aurein 1.2 is a 13-residue amphipathic peptide with antibacterial and anticancer activity. Aurein1.2 and its retro analog were synthesized to study the activity of the peptides in relation to their structure. The antibacterial test result showed the retro-analog is inactive. The secondary structural analysis by CD spectra indicated that both of the peptides at TFE/Water adopt alpha-helical conf...
