Abstract
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 in 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.
