A process for the production of a compound of formula (I), or a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable prodrug ester thereof, comprising cleaving a lactam of formula (II) wherein the symbols are as defined, with a base; and precursors therefor and processes for the preparation of the precursors. The compounds of formula (I) are pharmaceutically active compounds which are selective inhibitors of Cyclooxygenase (II).
The invention relates to a combination which comprises (a) a cyclooxygenase-2 inhibitor ('COX-2 inhibitor') and (b) a histone deacetylase inhibitor ('HDAI') for simultaneous, concurrent, separate or sequential use, especially for use in the treatment of pre-malignant colon lesions or a colon cancer or other malignancies in a mammal, particularly a human. The invention also relates to pharmaceutical compositions comprising such a combination and to a method of treating pre-malignant colon lesions (e.g.polyps)and colon cancer, as well as other malignancies, in a mammal, particularly a human, with such a combination. The present invention further also relates to a commercial package or product comprising such a combination.
