What is TERT-BUTYL 12-HYDROXY-4 7 10-TRIOXA-?
Description
Hydroxy-PEG3-t-butyl ester is a PEG linker containing a hydroxyl group with a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The t-butyl protected carboxyl group can be deprotected under acidic conditions.
Biological Activity
Tert-Butyl-12-hydroxy-4,7,10-trioxadodecanoate is an ADC linker for the synthesis of antibody drug conjugates (ADC), it is derived from patent WO2004008101A2 (compound 196). It can also be used as a PROTAC linker for PROTAC synthesis. .
in vitro
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
