Anti-metastatic activity of MPT0G211, a novel HDAC6 inhibitor, in human breast cancer cells in vitro and in vivo
Biochim Biophys Acta Mol Cell Res 2019 Jun;1866(6):992-1003.PMID:30867138DOI:10.1016/j.bbamcr.2019.03.003.
Triple-negative breast cancer (TNBC) is associated with an increased risk of metastasis and a poor prognosis. The invasive ability of TNBC relies on actin reorganization and is regulated by histone deacetylase 6 (HDAC6). The present study aimed to examine the effect of MPT0G211, a novel HDAC6 inhibitor, on cell migration and microtubule association in both in vitro and in vivo models of TNBC. Here MPT0G211 more selectively and potently targeted and inhibited HDAC6, compared with tubastatin A, another selective HDAC6 inhibitor. In vitro, MPT0G211 decreased the migration of the TNBC cell line MDA-MB-231, particularly when administered together with paclitaxel, and increased heat shock protein 90 (Hsp90) acetylation, leading to the dissociation of Hsp90 from aurora-A and proteasomal degradation. Furthermore, MPT0G211 significantly disrupted F-actin polymerization by increasing cortactin acetylation and downregulating slingshot protein phosphatase 1 (SSH1) and active cofilin expression. In vivo, MPT0G211 treatment significantly ameliorated TNBC metastasis. In conclusion, our results demonstrate that MPT0G211 reduces TNBC cell motility by promoting cortactin acetylation and aurora-A degradation, and inhibiting the cofilin-F-actin pathway via HDAC6 activity attenuation. MPT0G211 therefore demonstrates therapeutic potential for invasive TNBC.
The anticancer effects of MPT0G211, a novel HDAC6 inhibitor, combined with chemotherapeutic agents in human acute leukemia cells

Background: There are some limitations of standard chemotherapy for acute leukemia. Vincristine and doxorubicin are commonly used for acute leukemia, but they may induce serious side effects such as cardiomyopathy and neurotoxicity. Furthermore, chemotherapy resistance occurs more and more frequently. Therefore, effective treatment strategies are needed. Histone deacetylase 6 inhibition is considered as a potential therapeutic strategy for acute leukemia, since it is observed that HDAC6 is overexpressed in acute leukemia and regulates tumor survival. Combination therapy for cancer is used to minimize adverse drug effects, reduce drug dosage, enhance efficacy, and prevent drug resistance. In order to improve efficacy of chemotherapy agents of acute leukemia, this study will investigate the effects of combination MPT0G211, a novel histone deacetylase 6 inhibitor, with doxorubicin or vincristine on human acute leukemia cells. Results: MPT0G211 combined with doxorubicin induces DNA damage response on human acute myeloid leukemia cells. MPT0G211 can additionally increase Ku70 acetylation and release BAX to mitochondria. Ectopic expression of HDAC6 successively reversed the apoptosis triggered by the combined treatment. Moreover, co-treatment of MPT0G211 and vincristine may alter microtubule dynamics, triggering acute lymphoblastic leukemia cells arrest in mitotic phase followed by induction of the apoptotic pathway. Finally, MPT0G211 plus doxorubicin or vincristine can significantly improve the tumor growth delay in a tumor xenograft model. Conclusions: Collectively, our data highlighted that MPT0G211 in combination with chemotherapy drugs has significant anticancer activity, suggesting a novel strategy for the treatment of acute leukemia.
The novel histone de acetylase 6 inhibitor, MPT0G211, ameliorates tau phosphorylation and cognitive deficits in an Alzheimer's disease model
Cell Death Dis 2018 May 29;9(6):655.PMID:29844403DOI:10.1038/s41419-018-0688-5.
Alzheimer's disease (AD) is a dreadful neurodegenerative disease that leads to severe impairment of cognitive function, leading to a drastic decline in the quality of life. The primary pathological features of AD include senile plaques (SPs) and intracellular neurofibrillary tangles (NFTs), comprising aggregated amyloid β (Aβ) and hyperphosphorylated tau protein, respectively, in the hippocampus of AD patients. Histone deacetylase 6 (HDAC6) is a key enzyme in this neurodegenerative disease, in particular, as it relates to tau hyperphosphorylation. This study aimed to investigate the protective effects and mechanism of the novel HDAC6 inhibitor, MPT0G211, using an AD model. Our results indicated that MPT0G211 significantly reduced tau phosphorylation and aggregation, the processes highly correlated with the formation of NFTs. This HDAC6 inhibitory activity resulted in an increase in acetylated Hsp90, which decreased Hsp90 and HDAC6 binding, causing ubiquitination of phosphorylated tau proteins. In addition, a significant increase of phospho-glycogen synthase kinase-3β (phospho-GSK3β) on Ser9 (the inactive form) through Akt phosphorylation was associated with the inhibition of phospho-tau Ser396 in response to MPT0G211 treatment. In AD in vivo models, MPT0G211 appeared to ameliorate learning and memory impairment in animals. Furthermore, MPT0G211 treatment reduced the amount of phosphorylated tau in the hippocampal CA1 region. In summary, MPT0G211 treatment appears to be a promising strategy for improving the AD phenotypes, including tau hyperphosphorylation and aggregation, neurodegeneration, and learning and memory impairment, making it a valuable agent for further investigation.
