  • AMINOOXYLIPIDS FOR THE CONSTRUCTION OF SELF-ASSEMBLING LIPOSOMAL SYSTEMS ENABLING THEIR SUBSEQUENT MODIFICATION BY BIOLOGICALLY FUNCTIONAL MOLECULES
    Publication number: 20210292275
    Abstract: New aminooxylipids of general formula I, wherein n1=5-30 and X is polymethylene linker of the general formula II where n2=2-10, or X is polyethylene glycol linker of the general formula III, wherein n3=1-14 are provided. A method of preparation of the aminooxylipids of general formula I characterized in that the acylation of N-tert-butoxycarbonyl-polymethylenediamine {(CH3)3C—O—(C?O)—HN—(CH2)n—NH2, n=2-13}, or N-tert-butoxycarbonyl-polyethyleglycoldiamine {(CH3)3C—O—(C?O)—HN—(CH2)2—[O—(CH2)]n—O—(CH2)2NH2, n=1-14} with in position C(2) symmetrically branched fatty acids of general formula IV, wherein n1=5-30, in the presence of condensation reagent, or from acid of general formula IV derived acylchloride of general formula V wherein n1=5-30, produces N-Boc-aminolipids of general formula VI, wherein n1=5-30 a X is polymethylene linker of the general formula II or X is polyethylene glycol linker of the general formula III.
