The present invention relates to new mitomycin derivatives having excellent anti-tumour activities and which are of interest in the preparation of anti-tumour compositions. It is known that mitomycins have, in general, excellent anti-tumour activities. Examples of these mitomycins include mitomycin

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a new antitumor antibiotic substance and to its production. More particularly, it relates to a new antitumor antibiotic substance designated macracidmycin and to processes for the preparation thereof by the fermentation

BACKGROUND OF THE INVENTION This invention relates to a new substance having anti-tumour activity, a process for producing the same by fermentation and an antitumour composition containing the same. It was previously known to produce mitomycin A and/or B by fermentation, which process comprises

TECHNICAL FIELD A method of treating cancer, including carcinomas and sarcomas is claimed. The pharmaceutical composition containing compounds is also claimed. BACKGROUND OF THE INVENTION Cancers are a leading cause of death in animals and humans. The exact cause of cancer is not known, but links

BACKGROUND OF THE INVENTION The present invention relates to a novel compound, compositions containing the compound, the use of the compound in inhibiting the growth of malignant neoplasms in mammals, and a method of preparing the compound. A number of chemicals that inhibit the growth or otherwise

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to new anthracycline glycoside antitumor antibiotics, to processes for their preparation and to pharmaceutical compositions containing them. More, particularly, it relates to new antitumor antibiotics designated MA

SUMMARY OF THE INVENTION Tice.RTM. substrain BCG is used clinically as an immunotherapeutic agent against superficial bladder cancer. A boiling water extract of this BCG showed antitumor activity against a murine S180 sarcoma model and was fractionated into three fractions, A, B and C, by the use of

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a novel polysaccharide RBS substance and antitumor agent containing said substance as the effective component. 2. Description of the Prior Art As is known in the art, polysaccharides are obtained from various sources,

BACKGROUND OF THE INVENTION Approximately twenty percent of deaths from all causes in the United States are cancer-related. Although chemotherapy is a principal means of cancer treatment, the rate at which effective new drugs have become available for use in cancer chemotherapy has not increased
