PEG conjugates of potent I-4 integrin inhibitors, maintaining sustained levels and bioactivity in vivo, following subcutaneous administration
Mitsunobu reactions were employed to link t-butyl esters of I-4 integrin inhibitors at each of the termini of a three-arm, 40 kDa, branched PEG. Cleavage of the t-butyl esters using HCO2H provided easily isolated PEG derivatives, which are potent I-4 integrin inhibitors, and which achieve sustained...

Summary: | Mitsunobu reactions were employed to link t-butyl esters of I-4 integrin inhibitors at each of the termini of a three-arm, 40 kDa, branched PEG. Cleavage of the t-butyl esters using HCO2H provided easily isolated PEG derivatives, which are potent I-4 integrin inhibitors, and which achieve sustained levels and bioactivity in vivo, following subcutaneous administration to rats. |
