The present invention relates to novel co-crystals of pyrazolopyrimidines and a co-crystal former, wherein the co-crystal former is an organic carboxylic acid, preferably selected from the group of gentisic acid, succinic acid and xinafoic acid. The pyrazolopyrirnidkes, and in particular compound A are potent mGluR5 modulators and are useful for the prevention and treatment of acute and chronic neurological disorders, in particular CNS (central nervous system) disorders, which involve excessive glutamate induced excitation.
本发明涉及吡唑吡嘧啶的新型共晶体及共晶体形成剂,其中共晶体形成剂为有机羧酸,优选选自龙胆酸、琥珀酸和西那酸组。吡唑吡嘧啶,特别是化合物A是有效的mGluR5调节剂,可用于预防和治疗急性和慢性神经系统疾病,特别是涉及过度谷氨酸诱导兴奋的中枢神经系统疾病。
