This knowledge regarding the lipid bilayer disturbing effect is order oxcarbazepine 600mg without prescription, however order 600 mg oxcarbazepine free shipping, based on studies of model membranes 300mg oxcarbazepine with visa, which leaves many questions regarding the precise mechanism of the bacteria-killing activity. Several hundred peptides of this kind have now been described and classified according to structural characteristics; they include alpha- and beta-defensins, cathelicidines, cecropins, magainins, bactenecins, and protegrins. Those that are called cathelicidines and defensins dominate within the group of ver- tebrates. Cathelicidines in an active form vary in size between 12 and about 80 amino acid residues and appear in various ter- tiary structures. Amino acid sequences are given for the two peptides and for the human betade- fensin, also the intramolecular cystine disulfide bridges mentioned in the text. Defensins and other antimicrobial peptides are possible candidates to be pharmaceutical preparations for use in the clinical treatment of bacterial infections. A rather recently published example of such a candidate peptide is plectasin, an antimicrobial defensin isolated from the mold Pseudoplectania nigrella. It was reported that the plectasin- producing gene could be transferred to another fungus, which could produce and excrete plectasin in large amounts. This could be a solution to a serious problem with antibacterial peptides, which is to produce them in sufficient amounts and in a way that is economically defendable. The mice test is a parallel to the historically famous experiment with penicillin by Howard Florey in May 1940. In a recent report it was found, astonishingly, that the plectasin peptide of 40 amino acid residues with its amphipathic nature does not compromise bacterial membrane integrity as do similar defensins with the characteristic intramolecular cystine disulfide bridges stabiliz- ing their tertiary structures. Instead, it was actually found to interfere with bacterial cell wall synthesis, which was originally observed as severe cell-shaped deformations occurring in its presence. In more detail, the action of plectasin was more like the glycopeptide antibiotics (such as vancomycin, Chapter 5) found to form a stoichiometric complex with an intermediate in the biosynthetic pathway of cell wall formation. This intermediate is the glycopeptide–lipid complex, which translocates across the cytoplasmic membrane to the outside, where the glycopeptide is incorporated into the peptidoglycan polymer through the activity of transglycosylases and transpeptidases (see Chapter 4). It can be concluded that plectasin is a promising substance for further drug development. The results obtained seem to show that in the future, antibacterial peptides could play an important role in the treatment of infectious disease. One obstacle is that they are peptides susceptible to degradation in the gastrointestinal tract. This could, for example, be to inhibit the adhesion of bacteria to the epithelial cells of the ureters in the urinary tract in severe infections in the upper parts of this tract. This complexity and the fact that trans- port through the syringe needle requires energy makes it likely that the proper secretion mechanism could be inhibited without interfering with the growth of the bacterium. Small molecular inhibitors with this effect have been identified and ought to be developed into anti-infectious remedies. The new and important aspect of this approach is that only the pathogenicity is inter- fered with; bacterial growth and survival are unaffected. This is different from other antibacterial agents and eliminates the immediate risk of resistance development. Bacterial growth is normal, which means that mutations affecting the pathogenic- ity inhibition are not selected. Inhibition of Bacterial Fatty Acid Synthesis Pharmaceutical companies have to a large extent retreated from the field of antibacterial drugs, concentrating instead on chronic diseases, which has market advantages. Earlier, there was a cooperation between the health care and pharmaceuti- cal industries, which has now ceased, particularly regarding antibacterial agents. It was therefore very encouraging that the Merck pharmaceutical company took on the work of character- izing and developing a new approach to antibacterial action. As it turned out, it also became a good illustration of the great risks involved with developing a new antibacterial agent. This particular approach began with a report about a new antibiotic produced by the soil bacterium Streptomyces platensis isolated from a soil sample from South Africa. The finding was the result of a large screening program involving 250,000 extracts from drug-producing microorganisms. Itturnedouttobe a small molecule (molecular mass: 441 Da), consisting of two distinct structural elements: 3-amino-2,4-dihydroxybenzoic acid and lipophilic pentacyclic ketolide, linked together by an amide bond. Platensimycin showed a new mechanism of action, inter- fering selectively with the enzymatic elongation mechanism at the bacterial synthesis of fatty acids, which in sizes of 8 to 18 carbon atoms build bacterial membranes and cell surfaces. It ought to be pointed out here that inhibition of bacterial fatty acid synthesis for antibacterial action was used before in the action of the tuberculostatic agent of isoniazid, discussed in Chapter 9. So far, platensimycin has only been tested in vitro and in preliminary animal experiments with mice, where it showed inhibiting effects against staphylococci and pneumococci similar to those of penicillin against susceptible strains of these bacteria. There is still a long way to a clinically useful agent, and there would be a risk of resistance by mutational enzyme changes. Again it is interesting that the extensive research work regarding platensimycin was performed and the cost defrayed by a large pharmaceutical company, which by economic con- siderations seems to continue research regarding antibacterial agents. To explain the scarcity of new antibacterial agents and the risks involved in their development, the future potential of platensimycin is important to assess.
