Triethylamine → HCID 44299404, compound

Participants

Reaction Steps

3.0 mg of DPDPE (Tyr-D-Pen-Gly-Phe-D-Pen) was dissolved in 5 ml of anhydrous acetonitrile. A 20% molar excess of PEG reagent (either mPEG-SPA 5K [27.9 mg] or mPEG-SPA 2K [11.1 mg]) and triethylamine (0.8 μl) was added to the DPDPE. The reaction was allowed to proceed at room temperature under an argon atmosphere for 2 days. The sample was diluted to 15 ml with deionized water and lyophilized. The PEG-DPDPE powder was reconstituted in 5 ml of deionized water and purified on a Superdex 30 size exclusion column. The pertinent fractions were pooled together, dialyzed against water and frozen until in situ perfusion experiments.
