标题:A sortase-click reaction suite for synthesis of multivalent dendrimeric protein assembly

摘要:The present invention relates to synthesis of bio-conjugates and well-defined multivalent protein dendrimer assembly by a general and straightforward chemo- enzymatic method. The method involves a simple two-step process in which proteins appended with an orthogonal label by facile sortase-mediated ligation are conjugated to a multivalent dendritic scaffold using the versatile copper-catalyzed azide-alkyne cycloaddition reaction. The 'Sortase-Click' strategy produces satisfactory yield of dendrimers under mild conditions from readily available His6 -tagged proteins and serves as a powerful general strategy for covalent assembly of bio-conjugates and protein dendrimers.

摘要:A method for the synthesis of 1,3-di(chloropropyl)-5-tert-butyl benzene includes the steps of conducting Friedl-Crafts alkylation of 1,3-diisopropyl benzene by tert-butyl chloride in the presence of an alkylation catalyst to obtain 1-tert-butyl-3,5-diisopropylbenzene; peroxidizing the 1-tert-butyl-3,5-diisopropyl benzene by gaseous oxygen in the presence of a peroxidation catalyst in a basic solution to obtain 1,3-di(peroxypropyl)-5-tert-butylbenzene; reducing the 1,3-di(peroxypropyl)-5-tert-butylbenzene with a reducing agent to 1,3-di(hydroxylpropyl)-5-tert-butylbenzene; and chlorinating the 1,3-di(hydroxypropyl)-5-tert-butylbenzene to obtain 1,3-di(chloropropyl)-5-tert-butyl benzene.
