Document Type and Number:
WIPO Patent Application WO/2020/103175
Kind Code:
A1
Abstract:
Disclosed are a combretastatin derivative lyophilized powder injection and a preparation method therefor. The lyophilized powder injection is constituted by a combretastatin derivative phospholipid complex, a stabilizer, and a lyophilized protective agent. The preparation method comprises: the preparation of the combretastatin derivative phospholipid complex; pressurized homogenization; and freeze drying. The lyophilized powder injection is dissolved in a 5% glucose or 0.9% saline injection for use, and is applicable in intravenous injection, intravenous infusion, or direct oral administration to treat non-small-cell lung cancer, liver cancer, and colon cancer. The lyophilized powder injection prepared per the present invention has a high drug-to-lipid ratio and low toxic side effects, improves the hydrophilicity and lipophilicity of a combretastatin derivative, provides a certain degree of sustained-release effect and passive targeting, increases oral bioavailability, reduces the dosage for intravenous administration, enhances attenuation, and has great resolubility; moreover, the preparation method has a simple process and is easy for industrial production.
