    • The invention concerns a new lipoteichoic acid which can be isolated from the new Streptococcus sp DSM 8747. The new LTA is called LTA-T. It has a lipid anchor, which is a galacto-furanosyl-beta-1-3-glycerol with different rests of fatty acids esterified to the two adjacent hydroxy groups in the glycerol moiety and a non-glycosylated, linear, unbranched GroP chain with an unusual short hydrophilic GroP chain. The hydrophilic backbone consists of only 10 glycerophosphate units esterified with D-alanine in an extent of 30 %. The invention further concerns a pharmaceutical composition with the new LTA-T, optionally together with a monokine and/or hyaluronidase, a method of treating cancer comprising administration of an antitumor effective amount thereof, a method of producing the new compound and the new pharmaceutical composition, two degradation products of the new LTA-T and their use, and the new Streptococcus strain from which the new compound can be isolated.
    • 本发明涉及可以从新型链球菌DSM 8747中分离的新的脂磷壁酸。新的LTA称为LTA-T。 它具有脂质锚,其是半乳糖 - 呋喃糖基-β-1-3-甘油,其中不同的脂肪酸残基被酯化到甘油部分中的两个相邻羟基和非糖基化,线性,无支链的GroP链,其具有 不寻常的短亲水性GroP链。 亲水性主链由只有10%D-丙氨酸酯化的10个甘油磷酸酯单元组成。 本发明还涉及具有新的LTA-T,任选地与单核因子和/或透明质酸酶一起使用的治疗癌症的方法的药物组合物,包括施用抗肿瘤有效量的方法,制备新化合物的方法和新的药物组合物 ,新的LTA-T的两种降解产物及其用途,以及可以从其中分离出新化合物的新型链球菌菌株。
