The present invention relates to imidazole, oxazole and thiazole derivatives of tumor-targeted drug combretastatin A4, and phosphate esters, sulfonate esters or pharmaceutically acceptable salts, glycoside derivatives, solvates thereof, wherein the A-ring comprises a 3,5-dimethoxyphenyl group having a substituent at the 4-position. The pharmacological activity assays have demonstrated that the compounds of the present invention have good in vitro anti-tumor activity and excellent tubulin inhibitory effect.
摘要:
Techniques for realizing interactive information through multimedia are described to solve the problem in the prior art that a server can-not be accessed directly through a multimedia advertisement in multimedia. One embodiment of the techniques includes: a user terminal configured to parse and play the multimedia file to obtain the interactive information in the multimedia file. The user terminal accesses the server upon the trigger of the interactive information by the user. The techniques can be used to access the server through the interactive information in multimedia, and enables the transaction with the server more convenient and quickly.
摘要:
A method and system for realizing the interactive information through the multimedia are used to solve the problem in the prior art that it can not access the server through the multimedia advertisement. The applied method includes: A. user terminal parses and plays the multimedia file, which contains the interactive information carrying the communication sign (S101); B. the said user terminal accesses the server based on the trigger of the communication sign carried in the interactive information by the user (S102). A system for realizing the interactive information through the multimedia is also disclosed. The invention is used to access the server through the interactive information of the multimedia, and enables the transaction of the user more convenient and quick.
