Document Type and Number:
WIPO Patent Application WO/2009/033406
Kind Code:
A1
Abstract:
Provided is a kind of modified recombinant human endostatin that has the structure of CH3O-(CH2CH2O)m-CH2CH2CH2-NαH-Endostar, wherein the average molecular weight of CH3O-(CH2CH2O)m-CH2CH2CH2 is 20-40kD. The modified recombinant human endostatin enhances the stability in vivo, improves blood drug concentration, prolongs half-life, markedly increases the activity of inhibiting the endothelial cells proliferation, thus reduces drug dosage and decreases administration frequency. Its application for preparing anti-tumor pharmaceutical compositions is also provided.
