Description

SC239 is a cleavable 2-aminophenyl hemiasterlin agent-linker. SC239 can be as the agent-linker for ADC[1]. SC239 is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.

In Vitro

SC239 is composed of a tubulin-targeting 3-aminophenyl hemiasterlin warhead, SC209 (HY-144880), and a cleavable valine citrulline p-aminobenzyl carbamate linker functionalized with dibenzocyclooctyne (DBCO)[1].
The SC239 drug-linker is conjugated via a cleavable valine citrulline p-aminobenzyl carbamate linker functionalized with dibenzocyclooctyne (DBCO)[1].
SC239 conjugates exhibits better cytotoxic activity on Igrov1 cells which have lower expression levels of FolRα[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
