چکیده

Baumycin-negative mutants of Streptomyces coeruleorubidus ME130-A4 do not convert daunomycinone to daunomycin and baumycins. They biosynthesize daunomycin from aklavinone and e-rhodomycinone, indicating the glycosidation of the aglycone before the synthesis of daunomycinone. The biosynthetic pathway from a-rhodomycinone to daunomycin was further confirmed by studying the bioconversion of anthracyclinones and anthracyclines, which are presumed to be intermediates.

Microbial metabolism of anthracycline antibiotics daunomycin and adriamycin.

It has been shown that the antitumor antibiotics daunomycin (1) and adriamycin (4) are metabolized by microorganisms in a fashion similar to their metabolism by mammalian cells. Both the fungus Mucor spinosus and its cell-free extracts reduce the 13-keto group of daunomycin to give daunomycinol (2) by a TPNH-dependent process. Cell-free extracts of Streptomyces steffisburgensis convert adriamyc...

Antimutagenic Effect of Green Tea Extracts in Reverse Mutation Assay

In the present investigation, antimutagenic effect of petroleum ether, chloroform, methanol and water extracts of green tea was evaluated in Salmonella typhimurium TA-98 and TA-100 strains. Well known mutagens like sodium azide and daunomycin were added at a concentration of 10µl and 6µl per plate respectively resulted in the induction of histidine revertant colonies. However addition of 10 µl ...

IMMOBILIZATION OF MICROBIAL CELLS FOR THE PRODUCTION OF ORGANIC ACIDS

Techniques of immobilization of microbial- cells have been established by multifunctional reagents such as glutaraldehyed on a solid support. Immobilized cell reactor was designed to demonstrate stability of cross linking of whole cells for the production of organic acids. An eighty-six percent conversion of glucose was obtained for an eight hour retention time. The immobilized cell reacto...

Characteristics of uptake and cytotoxicity of a low-density lipoprotein-daunomycin complex in P388 leukemic cells.

We have investigated the in vitro drug-cell interaction and therapeutic effects of a low-density lipoprotein (LDL)-daunomycin complex as compared to free daunomycin. Uptake and retention of daunomycin were significantly enhanced in sensitive and resistant P388 leukemia cells when they were perfused with LDL-daunomycin complex relative to free drug. The interaction of the LDL-daunomycin complex ...
