Abstract: Provided is a kind of modified recombinant human endostatin that has the structure of CH3O—(CH2CH2O)m—CH2CH2CH2—N?H-Endostar, wherein the average molecular weight of CH3O—(CH2CH2O)m—CH2CH2CH2— is 20-40 kD. 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.

Abstract: This invention relates to a pharmaceutical composition used for treating cardiovascular diseases and a method for preparing it. The pharmaceutical composition mainly contains polysacchrides, saponins and amino acids extracted from Radix ginseng, Radix ophiopogonis and Fructus schisandrae chinensis. The method of preparing it includes the following steps: Radix ginseng, Radix ophiopogonis and Fructus schisandrae chinensis are decocted together in water; water extract or eluate is precipitated with alcohol or acetone, treated with macroporous adsorption resin and with ion exchange resin, and then separated to obtain pharmaceutical composition containing effective fractions of polysacchrides, saponins and amino acids. The above mentioned pharmaceutical composition can be formed into various preparations by mixing with any pharmaceutically acceptable auxiliary materials.
