ABSTRACT:
The present invention provides a compound having a formula: where R1is selected from the group consisting of alkyl, CH2(OC2H4)OCH3, and —(OC2H4)OCH3; n is 0-4; Olig is an oligomer having a formula:in-line-formulae description="In-line Formulae" end="lead"?-L-O-PAGR.R2]qin-line-formulae description="In-line Formulae" end="tail"?where L is a optional linker moiety selected from the group consisting of —CH2O—, —CH2OX—, —OX—, —C(O)—, —C(O)X, —NH—, —NHC(O)—, —XNHC(O)—, —NHC(O)X—, —C(O)NH—, —C(O)NHX—, andwhere X is alky1-6or is not present, Y is N or O or is not present, and R3is alkyl1-6; PAG is a linear or branched polyalkylene glycol moiety; R2is an alkyl1-22capping moiety if X is present or alkyl2-22if X is not present; and q is a number from 1 to the maximum number of branches on PAG; and m is 1-5.
