The present technology provides triazolones, tetrazolones, and imidazolones, or pharmaceutically acceptable salts thereof, preparation processes thereof, pharmaceutical compositions comprising the same, and uses thereof. The triazolones, tetrazolones, and imidazolones or their pharmaceutically acceptable salts exhibit inhibitory activity on VAP-1 and therefore can be usefully applied, e.g., for the treatment and prophylaxis of nonalcoholic hepatosteatosis (NASH).

The invention addresses radioresistance in cancer treatment involving radiotherapy and, in particular, limitations associated with the use of the drug sulfasalazine. Specifically, it provides a series of compounds for use as radiosensitizers in the treatment of cancers such as glioblastomas which are lethal and inherently resistant to radiotherapy. In one embodiment, the invention provides compounds of general formula (I), their stereoisomers and pharmaceutically acceptable salts for use as radiosensitizers in the treatment of cancer:

##STR00001##
