L-NMMA stability

[Stanislaw Kahl]

Hi,
Does anyone have the information about the stability in water or buffer 
solutions of two inducible nitric oxide synthase (iNOS) inhibitors: 
N(G)-monomethyl-L-arginine (L-NMMA) and S-methylisothiurea sulfate.  What 
are the best conditions (temperature, concentration) to store the stock 
solutions?  Thanks in advance for any information.
                                               St. Kahl
