Dendritic Poly-[N-(2-Hydroxyethyl)-L-Glutamine] as Potential Drug Carrier

Abstract: Dendritic poly-[N-(2-hydroxyethyl)-L-glutamine] (PHEG) with different molecular weights were synthesized by aminolysis of dendritic poly-(γ-benzyl-L-glutamate) (PBG), which was obtained by polymerization of the corresponding N-carboxyanhydride (NCA) with poly(amido amine) (PAMAM, starburst ® ) of the fourth generation as initiator. Dynamic light scattering (DLS) was used to determine the size of the polymeric carriers and to compare the dendritic polymer to the linear analogue. The body distribution and blood … Show more

“…[200] Six publications deal with grafting of NCAs on dendritic or hyperbranched "core polymers". [201][202][203][204][205][206] One research group used dendrimers of the poly(amide amine) type (PAMAM, 74), third generation, as the initiator for O-(b-d-glucopyranosyl)-l-Ser-NCA. The feed ratio was selected so that, on the average, one NCA reacted with one amino group.…”

“…In this way, ball-like oligomers with an outer sphere of tetraacetylglucose units was obtained, which were nicknamed "sugar balls". [201] The same type of dendrimers, but the fourth generation, was used for grafting gBzl-l-Glu-NCA, [202] and the benzyl ester groups were reacted with an excess of 2-aminoethanol. The resulting water-soluble globular poly(N e -hydroxyethyl-l-glutamine)s were claimed to be useful as drug carriers, and both blood compatibility and body distribution were studied.…”

“…[200] In sechs Publikationen wurde über das Pfropfen von Peptidketten auf hochverzweigte oder dendritische Polymere berichtet. [201][202][203][204][205][206] Eine Arbeitsgruppe verwendete Dendrimere des Poly(amidamin)-Typs (PAMAM, 74) der 3. Generation als Initiatoren für O-(b-d-Glucopyranosyl)-l-Ser-NCA.…”

“…[201] Dieselbe Art von Dendrimeren -nun die 4. Generationwurde für das Aufwachsen von g-Bzl-l-Glu-NCA verwendet, [202] und die g-Estergruppen wurden mit Aminoethanol umgesetzt. Die resultierenden wasserlöslichen Poly(N e -hydroxyethyl-l-glutamine) wurden als Pharmakaträger empfohlen.…”
