Bis-(3'-5')-cyclic dimeric adenosine monophosphate (c-di-AMP) is a bacterial second messenger implicated in the control of cell wall metabolism, osmotic stress responses and sporulation. Detection of c-di-AMP by the host cytoplasmic surveillance pathway (CSP) is known to elicit type I IFN responses through a signaling axis that involves STING, TBK1 and IRF3 [1, 2]. Involvement of the helicase DDX41 in the recognition of c-di-AMP has been suggested [3]. Recent studies have also demonstrated that c-di-AMP exerts strong adjuvant activities when delivered by the mucosal route [4, 5].

EMI1 (EGFR MaMTH Inhibitor 1) is a novel EGFR ex19del/T790M/C797S inhibitor.EMI1, while potently reducing the interaction of EGFR triple mutant with Shc1 in our MaMTH-DS assay, did not behave as a TKI and displayed no inhibition of the kinase activity of EGFR triple-mutant protein invitro.EMI1 did, however, more strongly inhibit the viability and increase the caspase 3/7 activ-ity of PC9 EGFR ex19del/T790M/C797S triple-mutant cells than noncancerous human bronchial epithelial (HBE) cells, as well as potently reduce PC9 EGFR ex19del/T790M/C797S organ-oid viability.EMI1 had a similar inhibi-tory effect on microtubule plus-end growth in both EGFR-WT and EGFR-C797S triple-mutant cells at 50–100 nM concentration. At 1 µM concentration, EMI1 strongly depolymerized inter-phase microtubules, perturbed spindle formation and induced strong mitotic block in PC9 EGFR ex19del/T790M/C797S cells after 20 h of treatment. EMI1 inhibited interaction of both proteins with EGFR at a level similar to that observed with Shc1, indicating it is not a specific inhibitor of the EGFR-Shc1 PPI interface. Rather, the loss of interaction mediated by EMI1 appears to be due to a more general alteration in EGFR activity.EMI1 induced EGFR degradation, and inhibited the activation of EGFR, ERK, AKT and S6 in PC9-ex19del and PC9-ex19del/T790M cells.

ABBV-744 is a BDII-selective BET bromodomain inhibitor that is being investigated to treat AML and metastic castration-resistant prostate cancer.BBV-744, a highly potent and selective inhibitor of the BD2 domain of BET family proteins with drug-like properties. In contrast to the broad range of cell growth inhibition induced by DbBi, the antiproliferative activity of ABBV-744 was largely, but not exclusively, restricted to cell lines of acute myeloid leukaemia and prostate cancer that expressed the full-length androgen receptor (AR). ABBV-744 retained robust activity in prostate cancer xenografts, and showed fewer platelet and gastrointestinal toxicities than the DbBi ABBV-07514.Analyses of RNA expression and chromatin immunoprecipitation followed by sequencing revealed that ABBV-744 displaced BRD4 from AR-containing super-enhancers and inhibited AR-dependent transcription, with less impact on global transcription compared with ABBV-075. These results underscore the potential value of selectively targeting the BD2 domain of BET family proteins for cancer therapy.
