摘要:
The present invention relates to a D 25 polysaccharide compound whose lipid has been partially removed and to its derivatives, wherein at least 85% by weight, preferably 90% of the compound, exists in aqueous solution in monomeric form. The 30 kD molecular weight polysaccharide compound extracted from the membrane proteoglycan of the bacterium Klebsiella pneumoniae is mentioned in particular. The amount of palmitic fatty acids which is bound to it in esterified form does not exceed 0.01% by weight of the compound and the amount of palmitic fatty acids which is associated with it in the free form does not exceed 0.1% by weight of the compound.
摘要:
The present invention relates to an aerosol composition containing a carrier agent capable of recognizing and binding to inflammatory and tumor foci mobilizing macrophages in their immediate environment, and an aerosol substrate, characterized in that the said carrier agent consists of a polysaccharide compound selected from the compound D 25, extracted from the membrane proteoglycans of the bacterium Klebsiella pneumoniae and having a molecular weight of 30.+-.0.10 Kd, and the compound oxidized D 25 in which the galactofuranoser residue (Gal.sub.f) of the linear polysaccharide chain of D 25 has been converted to arabinose, and their amide, ester or ether type derivatives, as well as their quaternary ammonium derivatives and salts, and also the derivatives obtained by grafting of phosphatides.
