Although viridins like wortmannin (Wm) have long been examined as anticancer agents, their ability to self-activate has only recently been recognized. Here, we describe the cytostatic effects of a self-activating viridin (SAV), which is an inactive, polymeric prodrug. SAV self-activates to generate a bioactive, fluorescent viridin NBD-Wm with a half-time of 9.2 hours. With cultured A549 cells, ...
Poly(ethylene glycol)-block-poly(aspartate-hydrazide) (PEG-p(Asp-Hyd)) was modified using either levulinic acid (LEV) or 4-acetyl benzoic acid (4AB) attached via hydrazone bonds. Paclitaxel (PTX) conjugated to the linkers formed PEG-p(Asp-Hyd-LEV-PTX) and PEG-p(Asp-Hyd-4AB-PTX). PEG-p(Asp-Hyd-LEV-PTX) and PEG-p(Asp-Hyd-4AB-PTX) assemble into unimodal polymeric micelles with diameters of 42 nm a...
A polymeric prodrug of prostaglandin E(1) (PGE(1)) was synthesized using galactosylated poly(L-glutamic acid hydrazide) (Gal-HZ-PLGA) as a biodegradable and targetable carrier to hepatocytes. Poly(L-glutamic acid hydrazide) was prepared by reacting poly(gamma-benzyl-L-glutamate) with hydrazine monohydrate, followed by reaction with 2-imino-2-methoxyethyl-1-thiogalactosides to obtain Gal-HZ-PLGA...
