a-Factor from Saccharomyces cerevisiae is a farnesylated dodecapeptide involved in mating. The molecule binds to a G-protein coupled receptor and hence serves as a simple system for studying the interactions between prenylated molecules and their cognate receptors. Here, we describe the preparation of a-factor and two photoactive analogues via Fmoc solid-phase peptide synthesis using hydrazinobenzoyl AM NovaGel (TM) resin; the structure of the synthetic a-factor was confirmed by MS-MS analysis and NMR; the structures of the analogues were confirmed by MS-MS analysis. Using a yeast growth arrest assay, the analogues were found to have activity comparable to a-factor itself. (C) 2010 Elsevier Ltd. All rights reserved.
