One kind of hydroxamic acids and their use different cancer cell proliferation and / or treatment of cancer in the preparation of inhibition

The present invention relates to the field of pharmaceutical chemistry A hydroxamic acids and their use different cancer cell proliferation and / or treatment of cancer in the preparation of inhibition. Hydroxamic acid compounds of the present invention is provided with the ability to inhibit proliferation of cancer cells, so as to achieve the purpose of the treatment of cancer. In particular, the inhibition of human skin melanoma cells (A375), human lung cancer cells (A549), human gastric cancer cells (MGC80-3), human esophageal cancer cells (TE-1) and human hepatoma cells (of HepG2) having excellent inhibition of cancer cells proliferative activity.
