Abstract

This invention relates to a cytotoxic phenylallyl phenylacrylate as shown in formula (1) and its analogs or phenylpropyl phenylpropionate as shown in formula (2), its analogs and its offcinal salts or solvates. This invention also relates to the preparation method for these compounds and the intermediates for preparation. Besides, this invention still relates to the pharmacological use of these compounds and their blended composites. The compounds in this invention have growth inhibitory activity towards tumor cells and are estimated to be used as antineoplastics.

Description

field of invention [0001] The present invention relates to the field of organic chemistry, medicinal chemistry and pharmacology, specifically, the present invention relates to phenylpropenyl phenylacrylate and phenylpropyl phenylpropionate and phenylpropionate propylphenyl ester compounds and their key intermediates and their preparation Methods and their use as medicines. Background of the invention [0002] At present, due to environmental pollution and other problems brought about by industrial development, the quality of human living environment continues to decline, and the incidence and mortality of tumor diseases are also increasing. However, the specific drugs for the treatment of tumor diseases are not satisfactory, and the malignant killing of normal cells caused by the low selectivity of cytotoxic drugs currently used in anti-tumor clinics limits the general applicability of such drugs. Therefore, searching for and discovering new highly selective cytotoxic antit...
