Provided herein are spirocyclic aminoquinolones of formula I and compositions containing the compounds. The compounds and compositions provided herein are useful in the prevention, amelioration or treatment of GSK- 3 inhibitors mediated diseases. In Formula (I): X1 is O or NR8; A is bond or substituted or unsubstituted C1-C2 alkylene, wherein the substituents when present are selected from one to four Q2 groups; where Q2 is alkyl or haloalkyl; p is 0 or 1; and q is an integer of 0 to 2.

economical process for the synthesis of a fused 2′,3′-dihydro-5’H-spiro[cyclopropane-1,4′-pyrido[3,2-b][1,4]oxazepine]-8′-carboxylic acid 1 on multikilogram scales is described. The synthesis features a streamlined isolation process from the Mitsunobu reaction by using one solvent system for a two-step process. Furthermore, a robust palladium-catalyzed intramolecular amination for the seven-membered heterocycle
The design, synthesis, and evaluation of 6-6-7 tricyclic quinolones containing the strained spirocycle moiety aiming at the GSK-3 beta inhibitor were described. Among the synthesized compounds, 44, having a cyclobutane ring on a spirocycle, showed excellent GSK-3b inhibitory activity in both cell-free and cell-based assays (IC50 = 36 nM, EC50 = 3.2 mu M, respectively). Additionally, 44 decreased the plasma glucose concentration dose-dependently after an oral glucose tolerance test in mice. (C) 2011 Elsevier Ltd. All rights reserved.
