Increasing or decreasing the pH may bring the peptide into aqueous  
solution by increasing the number of charged amino acids. If that doesn't  
work, you have to experiment. Methanol or acetonitrile would be obvious  

Why do you want to replace the DMSO in the first place? That reason may  
well limit your options with other solvents as well.
