Lazertinib (YH25448; GNS-1480) is an orally active, blood-brain barrier permeable third-generation EGFR tyrosine kinase inhibitor, as well as an ABCB1/ABCG2 inhibitor and a TRPA1 activator. Lazertinib exhibits IC₅₀ values of 0.4 mM and 0.2 mM against human ABCB1 and ABCG2, respectively. By inhibiting mutant EGFR signaling, EGFR phosphorylation and the downstream ERK/AKT pathway, as well as upregulating surface expression of EGFR/MET, Lazertinib induces cell cycle arrest, apoptosis, spontaneous calcium responses, hyperexcitability of dorsal root ganglion (DRG) neurons, and TRPA1-dependent pain-like behaviors. Lazertinib competitively binds to the substrate-binding sites of ABCB1/ABCG2, stimulates their ATPase activity without altering their expression or plasma membrane localization, thereby enhancing ADCC activity, acting as a chemosensitizer, and reversing ABCB1-mediated multidrug resistance. It exerts antitumor activity as a single agent or in combination with other drugs. Lazertinib is applicable to research related to non-small cell lung cancer, multidrug-resistant cancers, and paresthesia.

In Vitro

Lazertinib (0.1-1000 nM; 3 d) inhibits the viability of Ba/F3 cells expressing various rare EGFR mutations, with IC₅₀ values ranging from 3.5 nM to 108.3 nM^[1].
Lazertinib (10 nM (YUO-139 PDOs); 100 nM (YU-1092 PDCs); 72 h) upregulates EGFR expression on the surface of EGFR^G719S-mutant YUO-139 patient-derived organoids and EGFR^L861Q-mutant YU-1092 patient-derived cells after 72 h of treatment^[1].

Lazertinib (0.01-3.0 μM; 7 d, medium changed every 72 h) inhibits the long-term proliferation of PC-9 EGFR-mutant NSCLC cells in a concentration-dependent manner within 7 days, but fails to achieve complete growth inhibition at the tested concentrations^[2].
Lazertinib (100 nM; 4 h; 72 h) inhibits the phosphorylation of EGFR, ERK and AKT in PC-9 and HCC4011 EGFR-mutant NSCLC cells, but its inhibitory effects on ERK and AKT disappear by 72 h^[2].

It reduces the IC₅₀ values of Vincristine (HY-N0488A), Doxorubicin (HY-15142A), Mitoxantrone (HY-13502), and Topotecan (HY-13768), respectively, but shows no significant effect on Cisplatin (HY-17394)^[3].

In Vivo

Lazertinib (10 mg/kg; p.o.; once daily; days 27-29) achieves 26.3% and 141% tumor growth inhibition in Ba/F3 EGFR^G719S and YUO-139 EGFR^G719S xenograft models of non-small cell lung cancer, respectively^[1].

Dosage:

1 mM, 20 μL
Administration:

intraplantar; single dose

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
