Osimertinib (GMP Like)
Osimertinib (AZD-9291; Mereletinib) GMP Like is the GMP Like level of Osimertinib (HY-15772). GMP Like small molecules works appropriately as an auxiliary reagent for cell research manufacture. Osimertinib GMP Like is an inhibitor that selectively targets EGFRT790M and activated EGFR mutants. Osimertinib GMP Like exerts multiple anti-tumor mechanisms, including radiosensitization, induction of apoptosis and ferroptosis, as well as inhibition of cancer stemness. Osimertinib GMP Like suppresses EGFR nuclear translocation and downstream survival signaling pathways, significantly reduces cell viability and lipid droplet content, and also exerts synergistic effects with radiotherapy or specific targeted agents to effectively overcome drug resistance and radioresistance. Formulations of Osimertinib GMP Like modified with liposomes or iRGD enable sustained release, tumor-specific accumulation, and breakthrough of the blood-brain barrier limitation. Osimertinib GMP Like can be used in research related to radioresistant glioblastoma and non-small cell lung cancer.

Combination GMP Like with Osimertinib (500-2500 nM; 72 h) and Ganetespib (HY-15205) or Luminespib (HY-10215) enhances the inhibitory effect on cell viability of Osimertinib (HY-15772)-resistant non-small cell lung cancer cell lines PC9-OR2 and PC9-OR4, as well as the parental PC9 and H1975 cell lines[2].
Combination GMP Like with Osimertinib (50 nM; 12 d) and Luminespib significantly reduces the colony-forming ability of PC9, H1975, PC9-OR2 and PC9-OR4 non-small cell lung cancer cell lines[2].

Animal Model:BALB/c nude (4- to 6-week-old female; intracranial orthotopic xenograft model of radioresistant glioblastoma)[1]
-
Dosage:60 μl per 10 g body weight
-
Administration:i.v.; every 48 h
-
Result:Reduced tumor flux values significantly lower than control, saline + IR, free osimertinib/bortezomib + IR, iRGD-LP + IR, and Non-OB-LP + IR groups by day 15.
Extended median survival to 53.5 days, which was significantly longer than the 39.5 days observed in the saline + IR group (p < 0.0001) and the 48 days observed in the Non-OB-LP + IR group (p < 0.01).
Suppressed phosphorylated EGFR, phosphorylated ATM, and phosphorylated DNA-PKcs in tumor tissues harvested 2 h post-irradiation compared to other treatment groups.
-
Animal Model:BALB/cAJcl-nu/nu nude mice (7-week-old male; intracranial stereotactic implantation of 1×104 patient-derived GS-Y03 glioma stem cells)[3]
-
Dosage:5 mg/kg
-
Administration:p.o.; 5 times a week
-
Result:Improved survival compared to control mice, though survival was significantly shorter than in mice treated with the combination of osimertinib and brexpiprazole.
Did not cause notable adverse effects or reduce mouse body weight.
-
Animal Model:BALB/c A-nu (6-week-old female)[4]
-
Dosage:20 mg/L
-
Administration:p.o.; continuous via drinking water; 4 weeks
-
Result:Induced significant tumor shrinkage compared to vehicle control, with final mean tumor volume lower than control and chloroquine-only groups.
Increased Beclin-1 phosphorylation and slightly decreased ALDH1A1 and SOX2 protein expression in tumor tissue.
Caused no overt weight loss during the 4-week period.
Combination with chloroquine resulted in significantly greater tumor shrinkage than osimertinib alone (P < 0.05).
