摘要:
The present invention relates to novel compounds DC-92B and DC-92D having anthraquinone moiety and represented by the following planar structural formula (I) and to a process for producing the same. These compounds can be produced by culture of a microorganism belonging to the genus Actinomadura, and are useful as medicaments because of their antibacterial and anti-tumor activities. ##STR1## wherein R is a group represented by formula (II) or formula (III): ##STR2##
摘要:
New antibiotic compounds, Fortimicin factors KF and KG are produced by fermentation of microorganisms belonging to the genus Micromonospora. The antibiotic compounds are accumulated in the culture liquor and are isolated therefrom.

Phenazine compounds represented by the formula: ##STR1## wherein R is a hydrogen atom, an unsubstituted or substituted lower alkanoyl group, or an unsubstituted or substituted arylcarbonyl group have antibacterial and anti-tumor activities.Some of these compounds are produced by incubation of a microorganism.
摘要:
Disclosed is novel compound UCT-1003 represented by the following formula: ##STR1## and having anti-tumor activity. UCT-1003 is produced by culturing a microorganism belonging to the genus Paecilomyces.
摘要:
The sealed nonaqueous electrolyte secondary battery includes a nonaqueous electrolyte containing a gas generator that is decomposed to generate a gas when a prescribed battery voltage is exceeded, and a battery case that includes a current interrupt device that operates when the pressure within the battery case rises accompanying the gas generation. A positive electrode (10) has a positive electrode mixture layer (14) that contains at least a positive electrode active material (16). This positive electrode mixture layer (14) contains, as conductive agents, electroconductive carbon particles (18) and an expanded graphite (17) that has an average pore diameter of 0.2 μm to 0.5 μm.
