    摘要: N-acetylcarboxymethylchitosan derivatives are provided by the present invention. They are represented by the following formula (I): ##STR1## wherein R.sub.1 and R.sub.2 individually mean H or carboxymethyl group; P denotes a group R.sub.3 CO--, a group R.sub.4 NH-- or a group R.sub.5 O-- with assuming that R.sub.3 COOH denotes a compound having carboxyl group, R.sub.4 NH.sub.2 denotes a compound having amino group and R.sub.5 OH denotes an alcohol compound; Q stands for H or a group --OH; X represents a peptide chain containing same or different, one to ten amino acids; a.sub.1 and a.sub.2 individually represent zero or a positive integer, provided that both of a.sub.1 and a.sub.2 are not zero at the same time, and b stands for a positive integer; and having the following characteristic values (1)-(4):______________________________________ (1) carboxymethylation degree: 0.5-1.2 (2) molecular weight (as measured 3,000-300,000 by gel filtration method): (3) a/(a + b): 0.01-1 [provided that a = a.sub.1 + a.sub.2 ] (4) P/X ratio (molar ratio): 0.1-1 ______________________________________ P in the formula (I) can be the residue of a pharmaceutical compound. In this case, the substances of the formula (I) are derivatives of the pharmaceutical compound, which derivatives have been improved in the properties such as organotropism in vivo.P in the formula (I) can also be protective groups. In this case, removal of the protective groups from the substances of the formula (I) by deprotection makes it possible to provide such N-acetylcarboxymethylchitosan derivative which is useful as carrier for pharmaceutical compounds and which has the terminals of the so deprotected peptide chains capable of being linked with a pharmaceutical compound.There are further obtained such derivatives of the substances of the formula (I), in which derivatives some of the N-acetylcarboxymethylglucosamine units have been replaced by units having a high solubility in water.

    摘要: A carboxymethylmannoglucan comprising tetrasaccharide units represented by the following general formula (I) and salt thereof. Further, the invention discloses a carboxymethylmannoglucan derivative and salt thereof produced by subjecting part or the whole of mannose of the tetrasaccharide units to ring opening and subjecting part or the whole of glucose which constitute the main chain but have no mannose as a branch ##STR1## wherein R.sup.1 to R.sup.12 each represent a hydrogen atom or a carboxymethyl group.The compounds are useful as carrier for delaying the disappearance of a drug in the blood and for enhancing the organotropism of the drug for a carcinoma.
