Page/Page column 78; 79, (2015/12/31)
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.

Replacement of the piperazine sulfonamide portion of the PI3Kα inhibitor AMG 511 (1) with a range of aliphatic alcohols led to the identification of a truncated gem-dimethylbenzylic alcohol analog, 2-(5-(4-amino-6-methyl-1,3,5-triazin-2-yl)-6-((5-fluoro-6-methoxypyridin-3-yl)amino)pyridin-3-yl)propan-2-ol (7). This compound possessed good in vitro efficacy and pharmacokinetic parameters and demonstrated an EC50 of 239 ng/mL in a mouse liver pharmacodynamic model measuring the inhibition of hepatocyte growth factor (HGF)-induced Akt Ser473 phosphorylation in CD1 nude mice 6 h post-oral dosing.
