DBCO-PEG4-Biotin (ADIBO-NH-PEG2-Biotin) is an azadibenzocyclooctyne-biotin derivative containing a biotin moiety and 4 PEGs.

Cosyntropin (acetate) stimulates the release of corticosteroids such as cortisol from the adrenal gland.

KL-50 is a selective toxin toward tumors that lack the DNA repair protein O6-methylguanine-DNA-methyltransferase (MGMT), which reverses the formation of O6-alkylguanine lesions. KL-50 activates DNA damage response pathways and cycle arrest in MGMT-cells, independent of mismatch repair (MMR). KL-50 is promising for research of brain tumors that lack the DNA repair protein MGMT.
