Disclosed are compounds of the formula:
wherein
Ar is optionally substituted aryl or heteroaryl
R1 is hydrogen or alkyl;
R7 is hydrogen or alkyl;
R2 is hydrogen, halogen, alkyl or alkoxy; or
R1 and R2 taken together with the ring to which they are attached form a 5-9 membered saturated or aromatic ring optionally having a hetero atom selected from oxygen, sulfur or nitrogen;
R3 and R4 are independently hydrogen, alkyl, cycloalkyl, aryl or heteroaryl groups; or
R3 and R4 together with the nitrogen atom to which they are attached form a 5-8 membered ring; and
R5 is hydrogen, halogen, straight or branched chain lower alkyl having 1-6 carbon atoms, or straight or branched chain lower alkoxy or thioalkoxy having 1-6 carbon atoms,
which compounds are highly selective partial agonists or antagonists at human Corticotropin-Releasing Factor 1 (CRF1) receptors and are useful in the diagnosis and treatment of treating stress related disorders such as post trumatic stress disorder (PTSD) as well as depression, headache and anxiety.
揭示的化合物的结构如下:其中Ar是可选择取代的芳基或杂环芳基;R1是氢或烷基;R7是氢或烷基;R2是氢、卤素、烷基或烷氧基;或者R1和R2与它们附着的环一起形成一个5-9成员饱和或芳香环,该环可选择包含氧、
硫或氮等杂原子;R3和R4分别是氢、烷基、环烷基、芳基或杂环芳基;或者R3和R4与它们附着的氮原子一起形成一个5-8成员环;R5是氢、卤素、1-6个碳原子的直链或支链低烷基,或者1-6个碳原子的直链或支链低烷氧基或
