Discovery of 4-((3,4-dichlorophenyl)amino)-2-methylquinolin-6-ol derivatives as EGFR and HDAC dual inhibitors. Eur J Pharmacol 2023; 960:176114. [PMID: 37863412 DOI: 10.1016/j.ejphar.2023.176114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 10/04/2023] [Accepted: 10/11/2023] [Indexed: 10/22/2023]
Abstract
In patients with non-small cell lung cancer (NSCLC), the standard therapy consists of selective tyrosine kinase inhibitors that target epidermal growth factor receptors (EGFR). Nonetheless, their clinical utility is primarily limited by the development of resistance to drugs. HDAC inhibitors have been shown in studies to reduce the level of EGFR that is expressed and downregulate the EGFR-induced phosphorylation of AKT and ERK. Therefore, dual inhibitors of EGFR and HDAC provide a potential approach as combination treatment synergistically inhibited the growth of NSCLC. Herein, we examined the EGFR inhibition effect of twenty compounds which designed and synthesized by us previously. Among them, compounds 12c and 12d exhibited powerful antiproliferative activity against the NCI-H1975 cell line with IC50 values of 0.48 ± 0.07 and 0.35 ± 0.02 μM, correspondingly. In cell-free kinase assays, both 12c and 12d demonstrated target-specific EGFR inhibition against wild type (EGFRwt). Furthermore, the expression of EGFR and phosphorylation of the EGF-induced pathways were significantly suppressed under the treatment of 12c and 12d. Besides, both histones H3 and H4 exhibited increased levels of acetylation following 12c and 12d treatment. The animal experiments shown that 12d could prevent the growth of tumor, inhibited the expression of EGFR and the phosphorylation levels of p70 S6K, AKT and p38 MAPK in vivo, and did not cause organ damage to the mice during the experiment. Overall, the results illustrated that compound 12c and 12d could serve as effective EGFR and HDAC dual inhibitors in NSCLC cells. Our work offers an alternative strategy for NSCLC therapy.

Abstract
INTRODUCTION Histone deacetylase inhibitors (HDACIs) inhibit human osteosarcoma growth and cause apoptosis. Previously, we reported that HDACIs induce autophagy via the FOXO1 pathway. Whether there is involvement of autophagy in anti-osteosarcoma activity of HDACIs is still unknown. MATERIAL AND METHODS Confocal microscopy was performed to determine the formation of GFP-LC3 puncta. Western blotting was conducted to measure FOXO1, and autophagy-related protein levels. Small interference RNA (siRNA) specific for FOXO1 was transfected into U2OS cells to knock down FOXO1 expression level. Flow cytometry was performed to quantify cell death. RESULTS In this study, we first observed that trichostatin A (TSA) induces autophagy in human osteosarcoma cells. Moreover, we found that TSA treatment inhibits the mammalian target of rapamycin (mTOR) signaling pathway and enhances forkhead box O1 (FOXO1) transcriptional activity, which is responsible for the increased autophagy level, while suppression of FOXO1 function by siRNA knockdown markedly decreases TSA-induced autophagy. CONCLUSIONS We found that inhibition of autophagy, either by autophagy inhibitors or ATG gene knockdown, markedly enhances TSA-caused cell death. Taken together, our studies reveal the function of autophagy in HDACI-caused osteosarcoma cell death and thus support the development of a novel therapeutic strategy by combining HDACIs and autophagy inhibitors in osteosarcoma treatment.

Abstract
INTRODUCTION Neuropathic pain induced by brachial plexus avulsion (BPA) is a pathological condition. We hypothesized that inhibition of histone deacetylase (HDAC) could suppress BPA-induced neuropathic pain through inhibition of transient reception potential (TRP) overexpression and protein kinase B (Akt)-mediated mammalian target of rapamycin (mTOR) activation. METHODS We generated a rat BPA model; administered HDAC inhibitor tricostatin A (TSA) for 7 days postsurgery; and assessed the effects on HDAC expression, Akt phosphorylation, neuroinflammation, and mTOR activation. RESULTS TSA treatment alleviated BPA-induced mechanical hyperalgesia, suppressed Akt phosphorylation, and increased HDAC. We found suppressed proinflammatory cytokine levels, TRPV1 and TRPM8 expression, and mTOR activity in TSA-treated BPA rats. DISCUSSION Our results suggest that altered HDAC and Akt signaling are involved in BPA-induced neuropathic pain and that inhibition of HDAC could be an effective therapeutic approach in reducing neuropathic pain.

Abstract
Mangiferin functions as a perfect anti-oxidative compound in the diabetic heart, however, the exact mechanism remains to be elucidated. Here, we show the cardioprotective effect of mangiferin under high glucose-induced cardiotoxic condition mainly contributed to enhanced autophagy via suppressing mTORC1 downstream signal transduction. Primary neonatal rat cardiomyocytes were cultured to detect myocytes injury, autophagy, and related signal transduction under different doses of glucose and mangiferin treatment. High glucose (30 mM) reduced autophagic flux, and increased myocyte apoptosis and death compared with normal glucose (5.5 mM) as determined by variation of autophagy markers LC3-II, p62, parkin, GFP-LC3, or mRFP-LC3 fluorescence puncta, cell viability, cleaved caspase 3, cleaved PARP apoptosis indices, reactive oxygen species (ROS), MAO, and PI death indices. Conversely, mangiferin inhibited hyperglycemia associated oxidative stress by reducing ROS, MAO, cleaved caspase 3, and cleaved PARP generation, reestablishing cell viability, mitochondrial membrane potential, and enhancing autophagic flux, thereby preventing myocytes from high glucose-induced toxicity. Furthermore, cardioprotection with mangiferin was potentially related to the decreased mTOR phosphorylation and suppression of mTORC1 downstream signaling pathway. These data indicated the valuable effects of mangiferin on regulation of cardiac autophagy and pointed to the promising utilization for hyperglycemia control.
