Definitions

• the invention generally relates to triterpenequinone and triterpenephenol derivatives blocking the biosynthesis of phosphorylcholine by means of the selective blocking of the choline kinase enzyme in tumor cells or in cells affected by parasitic infection, and which are consequently applicable in the treatment of tumors and parasitic diseases or diseases caused by viruses, bacteria and fungi in animals, including human beings, as well as to a method for preparing the compounds of the invention.
• Choline kinase is the first enzyme of the Kennedy pathway or the phospatidylcholine (PC) synthesis pathway, and it phosphorylates choline to phosphorylcholine (PCho) using adenosine 5' -triphosphate (ATP) as a phosphate group donor.
• Ras genes form a family of the so-called oncogenes which have been widely studied since they are activated in 25-30% of all human tumors and in several of them in 90%. Ras proteins have an important role in the transmission of intracellular signals due to their involvement in the regulation of cell proliferation, terminal differentiation and senescence.
• Hemicholinium-3 (HC-3) as a relatively potent and selective blocking agent [Cuadrado A., Carnero A., Dolfi F., Jimenez B. and Lacal J. C. Oncogene 8, 2959-2968 (1993); Jimenez B., del Peso L., Montaner S., Esteve P. and Lacal J. C. J. Cell Biochem. 57, 141-149 (1995); Hernandez-Alcoceba, R., Saniger, L., Campos, J., Nunez, M. C., Khaless, F., Gallo, M. A., Espinosa, A., Lacal, J. C.
• Bisquaternized symmetric compounds derived from pyridinium have also been used and their ability to inhibit PCho production in entire cells has been evaluated (WO98/05644) . However, these derivatives have high toxicity levels limiting their extended therapeutic application.
• celastrol and pristimerin formed by a pentacyclic triterpene structure, induce apoptosis, said activity having been proved in human models with leukemia [Nagase, M., Oto, J., Sugiyama, S., Yube, K., Takaishi, and Sakato, N., Biosci. Biotechnol. Biochem 67, 1883 (2003)]. Nevertheless, these compounds show a serious toxicity at cell level which makes their development as useful drugs in the treatment of tumor conditions impossible. In this sense, application US 2004/0220267 describes celastrol and pristimerin derivatives which allow improving the toxicity problem.
