Gemtuzumab ozogamicin
Based on 2 publication(s) in Google Scholar
Gemtuzumab ozogamicin is an antibody-drug conjugate (ADC) consisting of a humanized immunoglobulin (IgG4) antibody directed against CD33 that is conjugated to the cytotoxic agent Calicheamicin (HY-19609). The antibody portion is Gemtuzumab (HY-P99971), and the drug-linker conjugate for ADC is N-Ac-γ-Calicheamicin-AcBut-NHS ester (HY-103688). Gemtuzumab ozogamicin can be used for the research of acute myeloid leukemia (AML).

Biological Activity
Description
In Vitro
Gemtuzumab ozogamicin (1-250 ng/mL ; 72 hours) has cell cytotoxicity in CD33-positive cells[1].
Gemtuzumab ozogamicin is an ADC. After binding of the antibody to CD33 and subsequent internalization, Calicheamicin mediates cytotoxicity to CD33-positive myeloid cells primarily through induction of DNA damage and subsequent apoptosis[1].
Gemtuzumab ozogamicin iproduces significant inhibition of colony formation in cultures of adult leukemic bone marrow cells[3].
Gemtuzumab ozogamicin (5-100 μg/L) suppressed the cell growth of HL-60, NOMO-1, NB-3 and NKM-1 cell lines in a dose-dependent manner[3].
Gemtuzumab ozogamicin (Compound GO) (1-100 nM, 24 h) induces dose-dependent capase activation at 10 and 100 nM in HL-60 cells[4].
Gemtuzumab ozogamicin (1 nM-1 μM, 72 h) kills 95.05% of HL-60 and 42.61% of K-562 cells[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:CD33-positive and CD33-deficient cells (HL60, HL60R, Kasumi-1, MV4-11, MV4-11R, primary CD34-positive HSPCs and primary AML blasts)
-
Concentration:0, 1, 5, 10, 25, 50, 100, 250 ng/mL
-
Incubation Time:72 hours
-
Result:Wildtype HL60 exhibited the highest sensitivity to GO (IC50=1.37 ng/mL), and almost all HL60 cells died at 5 ng/mL concentration.
HL60R, Kasumi-1, MV4-11 and MV4-11R showed similar sensitivity, with IC50s of 2.28, 3.19, 3.63 and 5.36 ng/mL, respectively.
IC50 in CD33-negative HL60R, Kasumi-1, MV4-11 and MV4-11R cells also increased significantly to 95.53, 50.78, 72.74 and 66.8 ng/mL, respectively.
