PURPOSE:To provide an antitumor agent containing lipoteichoic acid as an active component. CONSTITUTION:Lipoteichoic acid (LTA) is extracted from the whole bacterial cell of Gram-positive bacteria (e.g. bacterial strain of Streptococcus genus, Micrococcus genus, Lactobacillus genus, Staphylococcus genus, Bacillus genus, etc.), or an cell envelope containing cell wall and cell membrane separated from the cell of the above strain, by conventional extraction process. The objective antitumor agent is prepared by using the LTA as an active component. Since LTA is amphiphatic, soluble in both water and oily solvents and stable, it can be used as an agent for oral or parenteral administration. Dose: 0.1-100mg, preferably 1-20mg for each person. |
