The inexorable rise of antibiotic resistance in clinically important bacteria makes it vital not only to identify new classes of antimicrobial compounds but also to develop new derivatives of existing compounds that can extend their effective use.
This means planning the development of a product family upon a platform, which allows shorter lead times in developing new derivative models.
The results demonstrated that the lipophilicity of the tested compounds was not the sole parameter affecting antimycobacterial activity, as well as the potential and importance of developing new fluoroquinolone derivatives against mycobacterial infections.
Following our studies of the melatoninergic receptors, we have developed new tetrahydronaphthalenic derivatives of melatonin that have been tested as selective melatonin receptors ligands.
Background: The genetic engineering of antibiotic-producing Streptomyces strains is an approach that became a successful methodology in developing new natural polyketide derivatives.
As a part of our ongoing program of developing novel influenza virus inhibitors, some new derivatives of oseltamivir were prepared by modifying the amino group with glycyl, acetyl, benzyl and prolyl moieties.
However novel antimicrobials (new derivatives of previously developed antimicrobials or newly developed antimicrobials) for effective monotherapy or at least inclusion in new dual antimicrobial therapy regimens (combined with previously developed antimicrobials or novel antimicrobials) will likely be required.
However, novel antimicrobials (new derivatives of previously developed antimicrobials or newly developed antimicrobials) for effective monotherapy or at least inclusion in new dual antimicrobial therapy regimens (combined with previously developed antimicrobials or other novel antimicrobials) will ultimately be required if the upturn seen in 2013 is sustained into future years.
Herein, we report a facile synthesis procedure for some new derivatives of the newly developed isoxazoline, pyrrolo[3,4-d]isoxazole-4,6-dione pyrrolo[3,4-d]isoxazole-4,6-dione pyrrolo[3,4-d]isoxazole-4,6-dione pyrrolo[3,4-d]isoxazole-4,6-dione
