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].

CP-457493 is a bio-active chemical.

Erlotinib is an epidermal growth factor receptor inhibitor. Erlotinib binds in a reversible fashion to the adenosine triphosphate (ATP) binding site of the receptor.

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

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

CH5164840 is a potent and selective HSP90 inhibitor. CH5164840 showed remarkable antitumor activity against NSCLC cell lines and xenograft models. CH5164840 has potent antitumor activity and is highly effective in combination with erlotinib against NSCLC tumors with EGFR overexpression and mutations.

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.
