SRC and lung carcinoma: 2013; Soverini et al. 2018). The ability of stachydrine in targeting multiple RTKs makes it advantageous over Bcrl-Abl TKI. We previously identified that gallic acid, a plant extract from TCM, is effective against acute myeloid leukaemia (Gu et al. 2018). It is of interest to note that gallic acid also inhibits Bcr-Abl and Src signalling pathways in leukaemia and lung cancer (Chandramohan Reddy et al. 2012; Phan et al. 2016). Stachydrine and gallic acid are bioactive component of TCM. Increasing evidence has shown the various therapeutic activities of TCM in cancer (Xiang et al. 2019).
