Anticancer Drug Coming Out on TOPK
TOPK (T–lymphokine-activated killer cell–originated protein kinase) is a protein that is found in a wide range of human cancers and is believed to work as an oncogene, promoting tumor growth. Now, Matsuo et al. have developed a drug that can inhibit TOPK and can be delivered by multiple routes. The oral form of this drug was well tolerated by mice and allowed convenient and effective treatment. An intravenous form was even more effective, and providing it as a liposomal formulation was successful in eliminating hematological side effects while simultaneously promoting complete regression of the tumors. These results suggest that the TOPK inhibitor may be a viable anticancer agent, although human trials will be required before this drug can be used in the clinic.
Abstract
TOPK (T–lymphokine-activated killer cell–originated protein kinase) is highly and frequently transactivated in various cancer tissues, including lung and triple-negative breast cancers, and plays an indispensable role in the mitosis of cancer cells. We report the development of a potent TOPK inhibitor, OTS964 {(R)-9-(4-(1-(dimethylamino)propan-2-yl)phenyl)-8-hydroxy-6-methylthieno[2,3-c]quinolin-4(5H)-one}, which inhibits TOPK kinase activity with high affinity and selectivity. Similar to the knockdown effect of TOPK small interfering RNAs (siRNAs), this inhibitor causes a cytokinesis defect and the subsequent apoptosis of cancer cells in vitro as well as in xenograft models of human lung cancer. Although administration of the free compound induced hematopoietic adverse reactions (leukocytopenia associated with thrombocytosis), the drug delivered in a liposomal formulation effectively caused complete regression of transplanted tumors without showing any adverse reactions in mice. Our results suggest that the inhibition of TOPK activity may be a viable therapeutic option for the treatment of various human cancers.
