The reaction mechanism of thiourea dioxides with ammonia and primary aliphatic amines involves direct nucleophile (ammonia or amine) reactions with thiourea dioxides, followed by dissociation of the resulting adduct to form the sulfoxylate ion.
Two new guanidinylation reagents, N,N′-bis(ortho-chloro-Cbz)-S-methylisothiourea and N,N′-bis(ortho-bromo-Cbz)-S-methylisothiourea, were compared with the already known N,N′-bis(Boc)-S-methylisothiourea and N,N′-bis(Cbz)-S-methylisothiourea. The new reagents proved to be superior to the known reagents. The reactions with all the new reagents were accelerated by addition of DMAP. N,N′-Bis(ortho-chloro-Cbz)- and N,N′-bis(ortho-bromo-Cbz)guanidines are stable when treated with trifluoroacetic acid and can be converted to guanidines by hydrogenolysis.

The discovery and optimization of a series of tetrahydropyridopyrimidine based extracellular signal-regulated kinase (Erks) inhibitors discovered via HTS and structure based drug design is reported. The compounds demonstrate potent and selective inhibition of Erk2 and knockdown of phospho-RSK levels in HepG2 cells and tumor xenografts. (C) 2014 Elsevier Ltd. All rights reserved.
