摘要:
The present application relates to compounds represented by general formula (I), general formula (II) or general formula (III), and pharmaceutically acceptable salts or hydrates thereof, preparation methods thereof, and pharmaceutical compositions thereof. The compounds represented by general formula (I), general formula (II) or general formula (III) have inhibitory activities against isocitrate dehydrogenase 2 (IDH2), thereby being capable of treating IDH2 mutation-induced cancers.
摘要:
A process for the production of phenylalanine derivatives having quinazolinedione rings as represented by the general formula (1) or pharmaceutically acceptable salts thereof: (1) which comprises the following steps (a), (b) and (c): the step (a) of reacting an acylphenylalanine derivative represented by the general formula (2): (2) with a carbonyl-introducing agent and a specific anthranilic acid derivative to form a corresponding carboxy asymmetric urea derivative, the step (b) of converting the carboxy asymmetric urea derivative into a corresponding quinazolinedione in the presence of a carboxyl-activating agent, and the optional step (c) comprising the N-alkylation step of replacing the hydrogen atom attached to the nitrogen atom constituting the quinazoline- dione ring by an alkyl group with an N-alkylating agent and/or the deblocking step of deblocking R3' (a group corresponding to R3) when R3' is in a protected state. According to the process, phenylalanine derivatives having quinazolinedione skeletons can be produced in high yield favorable for industrialization.
