Erlotinib is a directly acting inhibitor EGFR tyrosine kinase inhibitor with an IC50 of 2 nM for human EGFR. Erlotinib D6 is a deuterium labeled Erlotinib .
Erlotinib-13C6 (CP-358774-13C6) is a 13C-labeled Erlotinib. Erlotinib is a directly acting EGFR tyrosine kinase inhibitor, with an IC50 of 2 nM for human EGFR[1].
Erlotinib reduces EGFR autophosphorylation in intact tumor cells with an IC50 of 20 nM. Erlotinib is used for the treatment of non-small cell lung cancer[1].Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process[2].

Erlotinib is an epidermal growth factor receptor inhibitor. Erlotinib binds in a reversible fashion to the adenosine triphosphate (ATP) binding site of the receptor.
TM608 is a potent selective c-Met inhibitor that targets mitochondria and kills erlotinib-resistant lung cancer cells, rapidly accumulates in mitochondria, and inhibits MET activation in high MET expression, erlotinib-resistant HCC827B cells (total cell l
WZ4002-hydroxyl is a WZ4002 derivative or WZ4002 analogue in which methoxy is replaced by hydroxyl and can be detected in 50% of patients with clinical resistance to gefitinib or erlotinib. WZ4002 has a basic chemical skeleton (covalent pyrimidine) that d
4-Chloro-6,7-bis(2-methoxyethoxy)quinazoline is a building block and synthetic intermediate.1,2,3,4,5It has been used as a precursor in the synthesis of receptor tyrosine kinase (RTK) inhibitors, dual RTK and histone deacetylase (HDAC) inhibitors, and anticancer compounds.1,2,3It is also a synthetic intermediate in the synthesis of EGFR inhibitors, including erlotinib , with antiproliferative activity.4,5
SB02024 is a VPS34 inhibitor. SB02024 activates cGAS-STING signaling and sensitizes tumors to STING agonist. SB02024 blocked autophagy in vitro and reduced xenograft growth of two breast cancer cell lines, MDA-MB-231 and MCF-7, in vivo. Vps34 inhibitor significantly potentiated cytotoxicity of Sunitinib and Erlotinib in MCF-7 and MDA-MB-231 in vitro in monolayer cultures and when grown as multicellular spheroids. Our data suggests that inhibition of autophagy significantly improves sensitivity to Sunitinib and Erlotinib and that Vps34 is a promising therapeutic target for combination strategies in breast cancer.
