Coupling of thiol and urea-type –NHC(X)NH2 (X = O or NH) groups is effective in promoting oxidative protein folding. In particular, a thiol compound coupled with a guanidyl (X = NH) group significantly accelerates the rates of folding processes and enhances the yields of native proteins.

The synthesis and antibacterial activity of a series of nocathiacin I derivatives (4-20) containing polar water solubilizing groups is described. Thiol-Michael adducts containing acidic polar groups have reduced antibacterial activity whereas those with basic polar groups have retained very good antibacterial activity. (c) 2005 Elsevier Ltd.
