Erlotinib Hydrochloride Mechanism of Action
Erlotinib reversibly binds the ATP-binding site of EGFR, inhibiting its autophosphorylation and downstream signaling (PI3K/Akt, RAS/RAF/MEK/ERK), which reduces tumor proliferation and survival. It’s effective against both wild-type and mutant EGFR in NSCLC and pancreatic models.pubmed.ncbi.nlm.nih.gov+5ncbi.nlm.nih.gov+5go.drugbank.com+5
Research & Pharmacology Context
-
Approved by China’s NMPA (HJ20170143) since 2019, mirroring global approvals in NSCLC and pancreatic cancer.
-
STATPEARLS summarizes its use as a first- to third-line therapy in EGFR?mutant NSCLC and in combination with gemcitabine for pancreatic cancer.
-
Clinically relevant pharmacokinetics: ~59% bioavailability, 36?h half-life, high protein binding—ideal for research dose modeling.
Research Applications
-
NSCLC and pancreatic cancer models, especially those with EGFR mutations
-
Kinase pathway assays targeting EGFR phosphorylation and downstream signals
-
Drug interaction studies involving CYP3A4 substrates/inhibitors
-
Resistance research comparing erlotinib with osimertinib or combination therapies
-
PK/PD modeling and biomarker exploration relating to rash or biologic response
