WebThe C17-THP derivative of 7α-(11-azidoundecanyl)-estradiol (4) was synthesized and coupled to an aminomethyl resin via a photolabile o-nitrobenzyl linker. Reduction of the azide by the Staudinger reaction to its corresponding amine followed by acylation using four activated NFmoc protected amino acids gave a first level of diversity. Subsequent … Webreceptor comprising 3β-cholesterylamine linked to the antibiotic vancomycin and bearing two glutamic acid residues in the linker region significantly enhanced the uptake of a fluorophore linked to a L-Lys-D-Phe-D-Ala tripeptide.
