A class of substituted phenylpyrimidine compounds are disclosed which are potent inhibitors of the excitatory amino acid, glutamate. Such compounds are useful in the treatment or prevention of a range of CNS disorders including cerebral ischaemic damage and epilepsy.
wherein:
R1 is piperazinyl;
R2 is amino;
R3 is hydrogen, C1-C6 alkyl, trifluoromethyl, C1-C6 alkoxy, C1-C6 alkylthio, (C1-C6 alkyl)thio(C1-C6 alkyl), di[(C1-C6 alkyl)oxy] (C1-C6 alkyl), or CH2X wherein X is C1-C6 alkoxy, phenoxy or benzyloxy;
each of R4, R5, R7 and R8 is the same or different and is selected from hydrogen and halo, or
R4 and R5 together denote -CH=CH-CH=CH- in which case both R7 and R8 are hydrogen;
R6 is hydrogen, halo, nitro or amino;
and pharmaceutically acceptable acid addition salts thereof.
本研究公开了一类取代苯基嘧啶化合物,它们是兴奋性氨基酸谷氨酸的强效抑制剂。此类化合物可用于治疗或预防一系列中枢神经系统疾病,包括脑缺血损伤和癫痫。
