The utility of the nasal route for the systemic delivery of 17β-estradiol was studied using watersoluble prodrugs of 17β-estradiol. This delivery method was examined to determine if it will result in preferential delivery to the brain. Several alkyl prodrugs of 17β-estradiol were prepared and their physicochemical properties were determined. In vitro hydrolysis rate constants in buffer, rat plasma,...
Chloramine-T (CAT) is commonly used in radiolabeling of bioactive molecules by halogenation. CAT is used to release radioactive elemental iodine by oxidation of its salts. Unfortunately, CAT is a strong oxidizing agent and can cause significant damage to peptides and proteins. This may lower the yield of the iodination reaction and may produce undesirable side products. Recently, it was found that...
