needed for labelling acyclic ureas with carbon-11 (t1/2=20.4 min) as potential radiotracers for biomedical imaging with positronemissiontomography (PET). Herein, we describe the rapid and high-yield syntheses of unsymmetrical acyclic [11C]ureas under mild conditions (room temperature and within 7 min) using no-carrier-added [11C]carbonyl difluoride with aliphatic and aryl amines. This methodology is compatible

k inact/K i value of 2.3 ± 0.3 and 5.5 ± 0.4 × 10-3 μM-1 min-1, respectively. The library was also evaluated for minimum inhibitory concentration (MIC) againsttwo strains of Mtb, Mycobacterium smegmatis, and Mycobacteriumabscessus. Compounds 4a and 4c were activeagainst Mtb H37Rv mc26206 with MIC values of 3.12 and 1.5 μM, respectively. Closely related 4e showed similar activity against Mtb H37Rv
The present invention provides compounds for modulating protein kinase enzymatic activity for modulating cellular activities such as proliferation, differentiation, programmed cell death, migration and chemoinvasion. Compounds of the invention inhibit, regulate and/or modulate kinases, particularly Tie-2. Methods of using the compounds and pharmaceutical compositions thereof to treat kinase-dependent diseases and conditions are also an aspect of the invention.
