Patent ID: 8394755

Claim:
A compound characterized by the following Formula I: wherein: Z is a polynucleophile remnant derived from methyl glucoside, sorbitan, diglycerol, or triglycerol; each G is an independently selected (poly)glyceryl group; each (Hphob) is an independently selected hydrophobic moiety; each L is an independently selected primary linking group; each L′ is an independently selected primary linking group; each L″ is an independently selected secondary linking group; each (Nu) is an independently selected nucleophilic group; x is from 1 to 5; h is from 0 to 4; y is from 0 to 5; a is from 0 to 4; the sum of x+h+a is from 4 to 5; and the sum of h+y is from 1 to 5, provided that if Z is a polynucleophile remnant derived from sorbitan, then x is from 1 to 3, h=1, a is from 0 to 2, and y is from 1 to 3, or if Z is a polynucleophile remnant derived from methyl glucoside, then the compound comprises greater than 3 glyceryl units.
