The Journal of Antibiotics
|September 1, 1979
Summary
Researchers converted fortimicin E into novel 4-N-aminoacylfortimicins E. These new compounds exhibited limited antimicrobial activity against common bacteria.
Area of Science:
- Microbiology
- Medicinal Chemistry
Background:
- Fortimicin E is a minor metabolite produced by Micromonospora olivoasterospora.
- The same fermentation also yields fortimicin A and fortimicin B.
Purpose of the Study:
- To chemically synthesize novel derivatives of fortimicin E.
- To evaluate the antimicrobial potential of these new compounds.
Main Methods:
- Chemical modification of fortimicin E.
- Synthesis of four distinct 4-N-aminoacylfortimicins E.
- Antimicrobial susceptibility testing against Gram-negative and Gram-positive bacteria.
Main Results:
- Successfully synthesized four 4-N-aminoacylfortimicins E from fortimicin E.
- The synthesized compounds demonstrated weak antimicrobial activity.
- Activity was observed against a range of Gram-negative and Gram-positive microorganisms.
Conclusions:
- The conversion of fortimicin E to 4-N-aminoacylfortimicins E is feasible.
- These novel derivatives possess limited antimicrobial efficacy.
- Further research may be needed to enhance their antibacterial properties.
