The invention relates to novel compounds for use in the treatment or prophylaxis of cancers and other proliferative conditions that are for example characterized by cells that express cytochrome P450 1B1 (CYP1B1) and allelic variants thereof. The invention also provides pharmaceutical compositions comprising one or more such compounds for use in medical therapy, for example in the treatment of prophylaxis of cancers or other proliferative conditions, as well as methods for treating cancers or other conditions in human or non-human animal patients. The invention also provides methods for identifying novel compounds for use in the treatment of prophylaxis of cancers and other proliferative conditions that are for example characterized by cells that express CYP1B1 and allelic variants thereof. The invention also provides a method for determining the efficacy of a compound of the invention in treating cancer.

The present invention provides the use of an siRNA and paclitaxel composition in the preparation of a drug for treating hepatocellular carcinoma, wherein the composition is composed of siCYP1B1, siP-gp and paclitaxel in a ratio of 1:1:1. Based on research on increased expression of CYP1B1 and P-gp proteins in hepatocellular carcinoma under hypoxia and reduced drug sensitivity of hepatocellular carcinoma to paclitaxel under hypoxia, the present invention seeks siRNA that can target and knock down CYP1B1 and P-gp. The present invention uses siRNA to target and knock down CYP1B1 and P-gp, thereby reducing the expression of CYP1B1 and P-gp, reversing the drug resistance of hepatocellular carcinoma to paclitaxel, and enhancing the cell cycle arrest mediated by paclitaxel.
