Chemobiosynthesis of new antimalarial macrolides.

Macrolides in dermatology

Erythromycin was the first macolide discovered in 1952. In 1990s new macrolides including clarithromycin, azithromycin, and dirithromycin were introduced to the market. We provide a review of their structure, pharmacokinetics, mechanisms of action, and indications in dermatology.

In vitro activities of antibiotics against Plasmodium falciparum are inhibited by iron.

The in vitro activities of cyclines (tetracycline, doxycycline, minocycline, oxytetracycline, and rolitetracycline), macrolides (erythromycin, spiramycin, roxithromycin, and lincomycin), quinolones (norfloxacin and ofloxacin), rifampin, thiamphenicol, tobramycin, metronidazole, vancomycin, phosphomycin, and cephalosporins (cephalexin, cefaclor, cefamandole, cefuroxime, ceftriazone, cefotaxime, ...

10-membered macrolides from the insect pathogenic fungus Cordyceps militaris BCC 2816.

Three new 10-membered macrolides (1-3) have been isolated from the entomopathogenic fungus Cordyceps militaris BCC 2816, together with six known compounds, cepharosporolides C (4), E (5), and F (6), 2-carboxymethyl-4-(3'-hydroxybutyl)furan (7), cordycepin (8), and pyridine-2,6-dicarboxylic acid. The structures were determined by analysis of NMR data, and an X-ray analysis was performed to confi...

Antimalarial Activity of the Myxobacterial Macrolide

Cryptolepine and development of new antimalarial agents

Natural product-derived drugs exemplified by quinine, isolated from South American Cinchona species and artemisinin discovered in China are of immense importance for the treatment of malaria. Although malaria parasites resistant to artemisinin have not yet been found in malaria patients, the need for new antimalarial agents remains. The burden of malaria is heaviest in Africa where over a milli...
