Abstract:
A drug combination with antitumor effects, contains styrene acid derivatives and antitumor medicaments with same or different specifications of unit preparations that can be simultaneously or separately administrated, as well as pharmaceutically acceptable carriers. The joint use of trans-styrene acid derivatives and antitumor drugs provides synergistic action, and the use of trans-styrene acid derivatives combined with a part of antitumor drugs can further exert the toxicity attenuation effects, showing a good clinical application prospect.

Claim (Index 9):
A method for preparing the drug combination of  claim 1 , comprising mixing a trans-styrene acid derivative, an antitumor medicament, and a pharmaceutically acceptable carrier,\n wherein the styrene acid derivatives has formula (I): Wherein, R 1 , R 2 , R 3 , R 4 , and R 5  are preferably hydrogen, hydroxyl group, and methoxyl group, in which R 1  is more preferably hydrogen, R 2  is hydroxyl group, R 3  is methoxyl group, R 4  is hydrogen, and R 5  is hydrogen. Said styrene acid derivatives have a cis- or trans-structure, in which trans-structure is preferable.
