A novel water-soluble gossypol derivative increases chemotherapeutic sensitivity and promotes growth inhibition in colon cancer.
Compound 1 ((-)-gossypol) has been long known as a chemical anticancer agent. With its low water solubility and toxicity, it is not widely used as a commercial drug. To overcome these disadvantages, several novel derivatives of gossypol were designed, synthesized, and analyzed. One of the derivatives, compound 7 (6-aminopenicillanic acid sodium-gossypolone), was identified with great water solubility and anticancer property, suggested by inducing a dramatically decrease in Bcl-2 and Bcl-xL protein expression level found in vitro and growth inhibition of murine colon tumor in vivo. Furthermore, it was also recognized with less toxicity than compound 1 in vivo and significantly increased chemotherapeutic sensitivity against colon cancer in combination with traditional chemotherapeutic agent 5-fluorouracil. Therefore, it is concluded that compound 7 is superior to parent compound 1, and further preclinical studies of compound 7 is necessary for colon cancer therapy.
