Definitions
- the present invention provides a telomerase-inhibiting ENA oligonucleotide conjugate or a pharmacologically acceptable telomerase that suppresses the action of telomerase specifically expressed in cancer cells and is effective in treating and preventing diseases such as cancer.
- Salts, pharmaceutical compositions containing them as an active ingredient, use of these compounds or pharmaceutically acceptable salts thereof for producing the pharmaceutical compositions, or those compounds or pharmaceutically acceptable salts thereof The present invention relates to a method for preventing or treating a disease, which comprises administering a pharmacologically effective amount of a salt to a warm-blooded animal (particularly a human).
- telomeres The ends of chromosomes are called "telomeres". During cell division, telomeres shorten due to incomplete replication of chromosomal DNA during mitosis. When the telomeres reach a critical length, the remaining DNA becomes unstable and cells containing the shortened DNA typically enter senescence and eventually die. Such senescence and cell death are not observed in cells containing telomerase. Telomerase is a ribonucleoprotein enzyme that synthesizes one strand of telomeric DNA using the sequence contained in the RNA component of the enzyme as type III. Cells with telomerase activity typically do not undergo senescence and are therefore likely to remain immortal.
- Telomerase activity was measured in skin, connective tissue, accumulated fat, breast, lung, stomach, spleen, ovary, cervix, uterus, kidney, bladder, colon, prostate, central nervous system, retina and blood tumor cell lines. It is found in more than 85% of all malignancies, and in most cases is not found in normal cells (Feng et al., 1995, Science, 269: 1236-1241; Kim et al. 1994, Science, 266: 2011-2014; and PCT Application No. 93/23572, published November 25, 1993).
