Gal-ARV-771
Gal-ARV-771 is a galactose-modified derivative of ARV-771 (HY-100972). Gal-ARV-771 is activated in cells expressing SA-β-Gal, thereby releasing ARV-771. Gal-ARV-771 selectively induces Apoptosis. ARV-771 is a BET PROTAC degrader. Gal-ARV-771 can be used in the research of lung adenocarcinoma (Gal+linker: Gal-PAB (HY-188142); PROTAC: ARV-771 (HY-100972)).
For research use only. We do not sell to patients.

In Vitro
Gal-ARV-771 (100 μM; 16-24 h) is stable for 24 h in full cell culture medium, and is fully converted to active ARV-771 after 16 h of combined action of esterase and β-galactosidase[1].
Gal-ARV-771 (72 h) shows potent selective cytotoxicity towards senescent A549 cells with 5.17-fold higher activity relative to non-senescent A549 cells, with an IC50 of 640 nM for senescent A549 cells[1].
Gal-ARV-771 (1 μM; 24 h) induces selective apoptosis in senescent A549 cells, with minimal induction of apoptosis in non-senescent A549 cells[1].

Animal Model:NOD.Cg-Prkdcscid/J (female, 5 weeks old, severe combined immunodeficient, SCID)[1]
-
Dosage:20 mg/kg
-
Administration:i.p.; 5 days on / 2 days off; 19 days
-
Result:Produced a 74% tumor growth inhibition (TGI) when administered in combination with etoposide.
Did not produce comparable tumor growth inhibition as a single agent.
Significantly reduced tumor BRD4 protein expression levels when combined with etoposide.
Reduced tumor cell proliferation as measured by Ki-67 staining when combined with etoposide.
Increased apoptosis as measured by cleaved caspase-3 staining when combined with etoposide.
Reduced expression of the senescent biomarker p21 in tumors compared to etoposide alone when combined with etoposide.
Showed no significant toxicity, as evidenced by stable body weights throughout the study period.
