[Antitumor activity of bacterial fractions and related synthetic compounds]. 1984

I Azuma, and Y Yamamura

We have purified the cell-wall skeletons (CWS) of Mycobacterium bovis BCG, Nocardia rubra, Propionibacterium acnes and Listeria monocytogenes as the adjuvant-active principles of these bacterial cells. These cell-wall skeleton preparations were shown to have antitumor activities in experimental tumor systems. Especially BCG-CWS and N. rubra-CWS were applied for the treatment of human cancer. The synthetic immunoadjuvants such as cord factor, mycoloyl and quinonyl derivatives of N-acetylmuramyldipeptides were prepared and their immunological properties were investigated. The effectiveness of synthetic adjuvants on the stimulation of nonspecific host resistance against bacterial and viral infections was also discussed.

UI	MeSH Term	Description	Entries
D007251	Influenza, Human	An acute viral infection in humans involving the respiratory tract. It is marked by inflammation of the NASAL MUCOSA; the PHARYNX; and conjunctiva, and by headache and severe, often generalized, myalgia.

D008087	Listeria	A genus of bacteria which may be found in the feces of animals and man, on vegetation, and in silage. Its species are parasitic on cold-blooded and warm-blooded animals, including man.
D009369	Neoplasms	New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.

D009615	Nocardia	A genus of gram-positive, aerobic bacteria whose species are widely distributed and are abundant in soil. Some strains are pathogenic opportunists for humans and animals.	Micropolyspora
D002473	Cell Wall	The outermost layer of a cell in most PLANTS; BACTERIA; FUNGI; and ALGAE. The cell wall is usually a rigid structure that lies external to the CELL MEMBRANE, and provides a protective barrier against physical or chemical agents.	Cell Walls,Wall, Cell,Walls, Cell
D003311	Cord Factors	Toxic glycolipids composed of trehalose dimycolate derivatives. They are produced by MYCOBACTERIUM TUBERCULOSIS and other species of MYCOBACTERIUM. They induce cellular dysfunction in animals.	Trehalose Dimycolates,Cord Factor,Trehalose-6,6'-Dimycolate,Dimycolates, Trehalose,Factor, Cord,Factors, Cord,Trehalose 6,6' Dimycolate
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000276	Adjuvants, Immunologic	Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

D001500	BCG Vaccine	An active immunizing agent and a viable avirulent attenuated strain of MYCOBACTERIUM BOVIS, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.
