The Uses of gamma-Benzyl L-glutamate
L-Glutamic acid γ-benzyl ester is commonly used in the synthesis of polymers for biological applications. Some of the examples are:
- Synthesis of bioreducible block copolymers based on poly(ethylene glycol) and poly(γ-benzyl L-glutamate) for Intracellular drug delivery.
- Synthesis of biodegradable poly(L-glutamic acid)-b-polylactide for magnetic resonance imaging (MRI)-visible drug delivery system.
- Synthesis of pH and temperature-responsive diblock copolymers based on poly(L-glutamic acid).
Purification Methods
Recrystallise the ester from H2O and store it at 0o. [Estrin Biochemical Preparations 13 25 1971, Beilstein 6 IV 2538.]
