The invention relates to ethynyl-substituted tetrahydroquinolinone derivatives as well as their pharmaceutically acceptable salts. The invention further relates to a process for the preparation of such compounds. The compounds of the invention are group I mGluR modulators and are therefore useful for the control and prevention of acute and/or chronic neurological disorders.

effect of the fluorinated N-benzamide enaminone analogs on the T-type Ca2+ channel subunits Cav3.2 and Cav3.3. The meta-trifluoromethyl N-benzamide enaminone lead analogs altered the steady-state inactivation of Cav3.2 T-type Ca2+ channels, which resulted in a significant increase in the inactivation recovery time of the channels. There was no effect of fluorinated N-benzamide enaminone analogs on the gating
三氟甲基化的N-苯甲酰胺烯胺酮已被确定为治疗耐药性癫痫的潜在抗惊厥药。T型Ca 2+通道是抗癫痫药物的重要靶点。我们的实验室开发了几种氟化N-苯甲酰胺烯胺酮类似物,通过它们靶向T型 Ca 2+通道的能力进行了评估。使用全细胞电压钳记录,我们确定了两种对T型 Ca 2+通道具有显着抑制作用的间三氟甲基N-苯甲酰胺烯胺酮。这些化合物对电压激活的 Na 没有影响+频道。我们还评估了氟化N-苯甲酰胺烯胺酮类似物对T型 Ca 2+通道亚基 Cav3.2 和 Cav3.3 的影响。间-三氟甲基N-苯甲酰胺烯胺酮铅类似物改变了Cav3.2 T型Ca 2+通道的稳态失活 ,导致通道失活恢复时间显着增加。氟化N-苯甲酰胺烯胺酮类似物对T型 Ca 2+通道的门控机制没有影响,这可以通过对 Ca 的活化和失活时间常数的影响得到证明2+电流。相反,间-三氟甲基N-苯甲酰胺烯胺酮铅类似物改变了Cav3.3 T-型Ca
explored as a precursor for the synthesis of benzo-cyclohepta-quinolinone (BCQ) analogues following a domino reaction. The vinyl bromide-substituted benzocycloheptene was synthesized from himachalenes, extracted fromCedrusdeodara oil. The reaction proceeds through C-C bond formation followed by palladium catalyzed C-N cross-coupling and dehydrogenative aromatization in a consecutive and atom-economic approach
