摘要:
The present invention provides a pH-responsive lipid derivative represented by a structure represented by the following formula (i):
(in the above-mentioned formula, each symbol is as described in the specification), and a pH-responsive transport carrier which is useful as a transport carrier for safely and efficiently performing delivery of low-molecular-weight drugs and the like to tumor tissues.
摘要:
The present invention relates to the field of polymers used to form coatings on support surfaces. More particularly, the invention relates to a polymer having adherence properties, including to an organic or inorganic support, characterized in that it comprises at least one and preferably a plurality of consecutive or non-consecutive structural units, of formula (I) in which: - B represents a carbonyl or -NR'- unit, where R' represents a hydrogen atom, a C 1 to C 6 alkyl radical, a C 5 to C 6 acyl, carbamate or aryl radical; and - R represents: - a hydrogen atom, - a C 1 to C 6 , which is linear or branched, saturated or unsaturated and, if appropriate, substituted by one or more halogen atoms, - a C 5 to C 6 aryl radical, or - an acyl, acyloxy, alcoxycarbonyl or cyano radical.
