title: Multistep solid-phase synthesis of an antibiotic and receptor tyrosine kinase inhibitors using the traceless phenylhydrazide linker.
abstract: The hydrazide group is an oxidatively cleavable traceless linker for solid-phase chemistry. This linker technology was used to develop a multistep solid-phase synthesis of an antibiotic that is active against Mycobacterium tuberculosis. Furthermore, we describe an efficient method for the traceless synthesis of 2-aminothiazoles that display dual inhibitory activity against the receptor tyrosine kinases VEGFR-2 and Tie-2. The synthesis method proceeds through 9 steps on the solid phase and should give access to a much larger library of 2-aminothiazoles, from which a new class of anti-angiogenesis drugs may be developed.
