Bis-aryl Urea Derivatives as Potent and Selective LIM Kinase (Limk) Inhibitors
摘要:
The discovery/optimization of bis-aryl ureas as Limk inhibitors to obtain high potency and selectivity and appropriate pharmacokinetic properties through systematic SAR studies is reported. Docking studies supported the observed SAR. Optimized Limk inhibitors had high biochemical potency (IC50 < 25 nM), excellent selectivity against ROCK and JNK kinases (>400-fold), potent inhibition of cofilin phosphorylation in A7r5, PC-3, and CEM-SS T cells (IC50 < 1 mu M), and good in vitro and in vivo pharmacokinetic properties. In the profiling against a panel of 61 kinases, compound 18b at 1 mu M inhibited only Limk1 and STK16 with >= 80% inhibition. Compounds 18b and 18f were highly efficient in inhibiting cell-invasion/migration in PC-3 cells. In addition, compound 18w was demonstrated to be effective on reducing intraocular pressure (IOP) on rat eyes. Taken together, these data demonstrated that we had developed a novel class of bis-aryl urea derived potent and selective Limk inhibitors.
Copper-catalyzed N-Arylation of 2-Oxazolidinones. An Expeditious Route to Toloxatone
摘要:
3-Aryl-2-oxazolidinones are obtained in excellent yields through the copper-catalyzed N-arylation of 2-oxazolidinones with a variety of aryl iodides. With aryl halides containing both iodo and bromo substituents, a high C-I/C-Br selectivity can be achieved. The procedure has been successfully applied to the preparation of a key intermediate in the synthesis of linezolid and to develop an expeditious route to toloxatone.

catalytic amounts of an organosuperbase such as Barton's base enables this transformation to proceed with high yields and exquisite substrate functional‐group tolerance under ambient CO2 pressure and mild temperature. This report also provides the first proof‐of‐principle for the single‐operation synthesis of elusive seven‐membered ring cyclic urethanes.
