MedKoo CAT#: 200491

CAS#: 915019-65-7 (free base)

Description: Dactolisib, also known as BEZ235, is an orally bioavailable phosphatidylinositol 3-kinase (PI3K) inhibitor with potential antineoplastic activity. PI3K inhibitor BEZ235 specifically inhibits PIK3 in the PI3K/AKT kinase (or protein kinase B) signaling pathway, which may trigger the translocation of cytosolic Bax to the mitochondrial outer membrane, increasing mitochondrial membrane permeability; apoptotic cell death may ensue. Bax is a member of the proapoptotic Bcl2 family of proteins.

More Info: BEZ235 is a dual phosphatidylinositol 3-kinase (PI(3)K)/mammalian target of rapamycin (mTOR) inhibitor that is orally available and that has been shown to be effective in several malignancies in vitro. Recently, BEZ235 entered clinical trials for solid tumors.  

Biological target: Dactolisib (BEZ235) is a dual pan-class I PI3K and mTOR kinase inhibitor with IC50s of 4 nM/5 nM/7 nM/75 nM, and 20.7 nM for p110α/p110γ/p110δ/p110β and mTOR, respectively.
In vitro activity: BEZ235 reduced cell viability in a dose-dependent manner, as shown by CCK8 assays (Figure 1A). The IC50 values of BEZ235 for HL-60/VCR and K562/ADR cells were 66.69 nmol/L and 71.44 nmol/L, respectively. After treatment with different concentrations of BEZ235 for 24 h, the migration of both cell lines significantly decreased (Figure 1B). BEZ235 also induced apoptosis in the HL-60/VCR and K562/ADR cells in a dose-dependent manner (Figure 1C). Reference: Acta Pharmacol Sin. 2017 Mar; 38(3): 382–391. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5342661/
In vivo activity: Subsequently, the peeled tumors were subjected to paraffin embedded sections. The protein expressions of p53 and p21 in tumor sections were tested by IHC assays. In both K1 and C643 tumors, p21 expression was higher in NVP-BEZ235 treated mice compared with the controls, since an increased percent and stronger staining of p21 positive cells were observed. While only the mice bearing K1 tumors displayed greater portion and stronger staining of p53 positive cells, rather than C643 tumors. These results suggested a p53-independent mechanism of p21 up-regulation in NVP-BEZ235 treated C643 xenograft tumors, which was consistent with the results of in-vitro studies. Moreover, the mitotic cell marker, Ki67 was shown much weaker in the NVP-BEZ235 treated tumors than the control tumors, further suggested NVP-BEZ235 suppresses thyroid cancer cell proliferation (Figure 7C). Taken together, these results indicated that NVP-BEZ235 treatment inhibited tumor growth in mice injected with K1 cells or C643 cells and substantiate our findings that NVP-BEZ235 inhibits thyroid cancer growth independent of TP53 status.
