The present disclosure relates generally to the field of phosphodiesterase 10 (PDE10) enzyme inhibition by cinnoline compounds of Formulas: (I) and (II); wherein R'-R3 and R15-R18 are as defined herein. Still further, the present invention provides methods for synthesizing compounds with such activity and selectivity, as well as methods of and corresponding pharmaceutical compositions for treating a patient, e.g., mammals, including humans, in need of PDE inhibition. Treatment is preferably for a disease state that involves elevated intracellular PDE10 levels or decreased cAMP and/or cGMP levels, e.g., involving neurological or psychiatric syndromes, especially those states associated with psychoses, most especially schizophrenia or bipolar disorder, obsessive-compulsive disorder, and/or Parkinson’s disease. In particular, such psychoses, obsessive-compulsive disorder, and/or Parkinson’s disease are due at least in part to catabolism of intracellular cAMP and/or cGMP levels by PDE10 enzymes or where such an impaired condition can be improved by increasing cAMP and/or cGMP levels.
本公开涉及
磷酸二酯酶10(PDE10)酶被Formula(I)和(II)的
喹啉类化合物抑制;其中R'-R3和R15-R18如本文所定义。此外,本发明提供了合成具有此类活性和选择性的化合物的方法,以及用于治疗需要PDE抑制的患者,例如哺乳动物,包括人类的方法和相应的药物组合物。治疗最好用于涉及细胞内PDE10
水平升高或c
AMP和/或cGMP
水平降低的疾病状态,例如涉及神经系统或精神症候群,尤其是与精神病、强迫症、帕
金森病有关的状态。特别是这些精神病、强迫症和/或帕
金森病至少部分是由PDE10酶分解细胞内c
AMP和/或cGMP
水平引起的,或者这种受损状态可以通过增加c
AMP和/或cGMP
水平来改善。
