For instance, CFTRact-J027 is a safe and efficient CFTR (cystic fibrosis transmembrane conductance regulator) activator which increases intestinal fluid secretion (Cil et al., 2016), and ML281 is a nanomolar STK33 inhibitor that selectively kills KRAS cancers (Weïwer et al., 2012). Here, CFTR is linked to cancer.
