摘要:
Symmetrically and asymmetrically branched homopolymers are modified at the surface level with functional groups that enable forming aggregates with water insoluble or poorly water soluble pharmaceutically active agents (PAA). The aggregates formed are specifically induced by interaction of PAA and homopolymer and are different from aggregates that are formed by the polymer alone in the absence of the PAA or by the PAA alone in the absence of the polymer. Such aggregates can be used to improve drug solubility, stability, delivery and efficacy.
摘要:
Modified symmetrically branched polymers are combined with bioactive agents for a variety of purposes including drug delivery and conjugation to one member of a binding pair for use in an assay.
摘要:
A conjugate of a modified randomly branched asymmetric polymer without a core and a member of a binding pair is described. The modified randomly branched asymmetric polymer can contain chain branches, terminal branches or both. The modified randomly branched asymmetric polymer can contain random asymmetric branches or random asymmetric junctions. The binding pair can be an antibody, antigen or a ligand. The conjugate includes a drug.
