摘 要:OBJECTIVE Lung cancer is the leading cause of cancer death *** growth factor receptor(EGFR)mutation(s)is/are common in non-small cell lung cancer(NSCLC)in Asian population,resulting in lung tumor formation.L858 Rsubstitution mutation on exon 21 and in-flame deletion mutation on exon 19 are the two most common forms of EGFR *** targeted therapy using tyrosine kinase inhibitor(TKI)targeting EGFR shows promising initial response,however drug resistance is ***,it is needed to identify new inhibitors to tackle *** this study,we aim to investigate the effect of multiple single purified compounds derived from Chinese herbal medicines(CMHs)on a panel of NSCLC cell lines with different EGFR mutational statuses and TKI *** also examine the biological functional effect and drug action mechanism of these cell lines after drug *** We have reviewed the literature and selected ten single purified compounds derived from CMHs which exhibited the highest potential of cancer suppression effect in *** have recruited three EGFR-dependent NSCLC cell lines for drug screening using cytotoxicity assay.A549 is used as EGFR wild-type *** TKI-resistant NSCLC cell lines were used,H1975 harbors double mutation(EGFRL858R+T790M)and H1650 harbors EGFRexon 19 deletion.H2228is a NSCLC cell line which harbours EML4-ALK fusion gene and was used as EGFR-independent cell line *** assay was used to determine the drug efficacy and IC50 *** functional assays including cell cycle arrest analysis and apoptosis assay was used to determine the biological effect after drug *** MTT assay revealed that six out of ten candidate agents showed significant cancer-inhibiting effects in H1650 and *** compounds exhibited IC50 value at micro-molar levels while another three compounds exhibited IC50 at as low as nano-molar *** compound exhibited specificity on EGFR-dependent NSCLC
