The present invention describes new pyrazolo-pyrimidine derivatives of formula (I) or a pharmaceutically acceptable salt thereof; (I) wherein, R1 is halogen, cyano, or C1-C3alkyl optionally substituted by halogen; R2 is C1-C6alkyl optionally substituted one or more times by C1-C6alkyl, C2-C6alkenyl, hydroxyl, N,N-di-C1-C6alkyl amino, N-mono-C1-C6alkyl amino, O-Rg, Rg, phenyl, or by C1-C6alkoxy wherein said alkoxy again may optionally be substituted by C1-C6alkoxy, N,N-di-C1-C6alkyl amino, Rg or phenyl; C3-C6cycloalkyl optionally substituted by C1-C6alkyl, N,N-di-C1-C6alkyl amino or C1-C6alkoxy-C1-C6alkyl, and/or two of said optional substituents together with the atoms to which they are bound may form an annulated or spirocyclic 4 - 6 membered saturated heterocyclic ring comprising 1 - 2 O atoms; phenyl optionally substituted by C1-C6alkoxy; a 5 - 6 membered heteroaryl ring having 1 to 3 heteroatoms selected from N and O said ring being optionally substituted by C1-C6alkyl which may be optionally substituted by amino or hydroxy; Rg; or N,N-di-C1-C6alkyl amino carbonyl; and R is phenyl independently substituted two or more times by Ra, 2-pyridyl independently substituted one or more times by Rb, 3-pyridyl independently substituted one or more times by Rc, or 4-pyridyl independently substituted one or more times by Rd; which are generally interacting with MALT1 proteolytic and/or autoproteolytic activity, and in particular which may inhibit said activity. The present invention further describes the synthesis of said new pyrazolo-pyrimidine derivatives, their use as a medicament, especially by interacting with MALT1 proteolytic and/or autoproteolytic activity.
本发明描述了新的吡唑基嘧啶衍生物(I)或其药学上可接受的盐;(I)其中,R1是卤素、氰基或由卤素取代的C1-C3烷基;R2是C1-C6烷基,可选地由C1-C6烷基、C2-C6烯基、羟基、N,N-二C1-C6烷基氨基、N-单C1-C6烷基氨基、O-Rg、Rg、苯基或由C1-C6烷氧基取代的C1-C6烷基取代一次或多次,其中该烷氧基再次可选地由C1-C6烷氧基、N,N-二C1-C6烷基氨基、Rg或苯基取代;C3-C6环烷基,可选地由C1-C6烷基、N,N-二C1-C6烷基氨基或C1-C6烷氧基-C1-C6烷基取代,和/或两个可选取代基与它们连接的原子一起可以形成1-2个氧原子的环化或螺环4-6成员饱和杂环环,包括苯基,可选地由C1-C6烷氧基取代;具有1至3个异原子(N和O)的5-6成员杂环环,该环可选地由C1-C6烷基取代,该烷基可选地由氨基或羟基取代;Rg;或N,N-二C1-C6烷基氨基羰基;R独立地由Ra取代两次或两次以上,独立地由Rb取代一次或多次的2-吡啶基,独立地由Rc取代一次或多次的3-吡啶基,或独立地由Rd取代一次或多次的4-吡啶基;这些基本上与MALT1蛋白酶和/或自体蛋白酶活性相互作用,特别是可能抑制该活性。本发明进一步描述了所述新的吡唑基嘧啶衍生物的合成,它们作为药物的用途,特别是通过与MALT1蛋白酶和/或自体蛋白酶活性相互作用。
