摘要:
Nucleoside chemical compounds, which interact with specific structures of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) are disclosed. The compounds interfere with the activities of telomerase and reverse transcriptase, and are useful as antivirals, antibacterials and anticancer agents. Methods of treating or preventing cancers in patients involving administration of a therapeutically effective amount of a composition having an inhibitor or antagonist of the reverse transcriptases (RTs) expressed in cells of the patients are also disclosed. Method of using nucleoside analogs and other inhibitors of RTs in conjunction with DNA damaging agents such as genotoxic agents or radiation or photodynamic therapy or combinations these for the treatment of various cancers are also disclosed.
摘要:
An object of the present invention is to offer novel purine derivatives which exhibit an inhibitory action to nasal mucus secretion and are useful as pharmaceuticals, etc. and pharmaceutically acceptable salts thereof. The purine derivatives of the present invention are novel compounds which are represented by the following general formula (I). [In the formula, R is alkyl or cycloalkyl, or optionally-substituted phenyl or phenylalkyl; R' is hydrogen or -COOX; and X is alkyl, alkenyl, alkoxyalkyl, phenyl or phenylalkyl] The compounds of the present invention are useful as therapeutic and preventive agents to various types of rhinitis accompanied by acceleration of nasal mucus secretion and by sneezing reflex such as allergic rhinitis. Moreover, the compounds of the present invention are able to be administered orally and exhibit low toxicity, little side effect and high safety. Accordingly, a continuous administration for long term is possible and they have a very high utility as the drugs.
