Neurogenesis in Skeletal Muscle

This week in JACS, Korean guys have published a very interesting paper concerning the induce neurogenesis of human skeletal muscle cells.
Upon Neurodazine (Nz) treatment of C2C12 cells (skeletal muscle cells) develop a neuronal phenotype, they have shown also using a mouse 20K DNA chips that Nz upregulated in particular gene which is involved in inducing neuronal differentiation.

From a chemical point a view, these guys have synthesized an imidazole library with different substituents in 1,2, 4 and 5 on solid support (Wang resin), with amino-conjuguated diethylene glycol, more than 300 imidazoles have been obtained with a purity >70%. Three different polymer supported platforms have been realized, you will see below only one example using a benzylamine derivative. The imidazole ring has been synthesized with the classical multicomponent reaction with an aldehyde (R1CHO) , an 1,2-dicarbonyl compound (R2COCOR3) , and with ammonium acetate.



R1, R2, and R3 are mainly aromatic compounds
To see the other platforms, chemistry and biological tests see Supporting info.
