An object of the present invention is to provide a novel and useful galactose derivative, which is a constituent of a drug carrier, capable of improving the directivity to the liver and efficiently expressing the drug effect, a drug carrier containing the derivative, and the carrier and pharmaceutical It is providing the pharmaceutical composition containing these. The present invention relates to a galactose derivative represented by the following general formula (I), a drug carrier containing the derivative and a cationic lipid, and the carrier and a pharmaceutical (preferably, double-stranded RNA, double-stranded DNA, oligonucleic acid ). [Chemical 6] In Formula (I), R 1 represents hydrogen, optionally substituted alkyl having 1 to 10 carbon atoms, or 1- (D) -deoxylacto-1-yl. R 2 represents a saturated or unsaturated fatty acid residue having 10 to 30 carbon atoms. [Selection figure] None |
