Biomed Pharmacother 2024; 171:116101. [PMID: 38228032 DOI: 10.1016/j.biopha.2023.116101] [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: 09/25/2023] [Revised: 12/18/2023] [Accepted: 12/26/2023] [Indexed: 01/18/2024] Open
Abstract
OBJECTIVE Idiopathic pulmonary fibrosis (IPF) is a progressive and irreversible interstitial lung disease with a poor prognosis. Alpinetin (ALP), derived from Alpinia katsumadai Hayata, has shown potential as a therapeutic measure of various diseases. However, the utilization of ALP in managing pulmonary fibrosis and its underlying mechanisms are still not fully understood. METHODS A well-established mouse model of pulmonary fibrosis induced by bleomycin (BLM) was used in this study. The antifibrotic effects of ALP on histopathologic manifestations and expression levels of fibrotic markers were examined. Subsequently, the impact of ALP on fibroblast differentiation, proliferation, apoptosis, and associated signaling pathways was investigated to elucidate the underlying mechanisms. RESULTS In the present study, we observed that ALP effectively mitigated BLM-induced pulmonary fibrosis in mice, as evidenced by histopathological manifestations and the expression levels of fibrotic markers. Furthermore, the in vitro experiments demonstrated that ALP treatment attenuated the ability of fibroblasts to differentiate into myofibroblasts. Mechanically, our findings provided evidence that ALP suppressed fibroblast-to-myofibroblast differentiation by repressing TGF-β/ALK5/Smad signaling pathway. ALP was found to possess the capability of inhibiting fibroblast proliferation and promoting apoptosis of fibroblasts induced by TGF-β. CONCLUSION In general, ALP may exert therapeutic effects on pulmonary fibrosis by modulating the differentiation, proliferation, and apoptosis of fibroblasts. Although its safety has been demonstrated in mice, further studies are required to investigate the efficacy of ALP in treatment of patients with IPF.

Abstract
Abstract
Background
During cell apoptosis, the C-terminus of BAP31 is cleaved by caspase-8 and generates p20BAP31, which has been shown to induce an apoptotic pathway between the endoplasmic reticulum (ER) and mitochondria. However, the underlying mechanisms of p20BAP31 in cell apoptosis remains unclear.
Methods
We compared the effects of p20BAP31 on cell apoptosis in six cell lines and selected the most sensitive cells. Functional experiments were conducted, including Cell Counting Kit 8 (CCK-8), reactive oxygen species (ROS), and mitochondrial membrane potential (MMP) assay. Then, cell cycle and apoptosis were investigated by flow cytometry and verified by immunoblotting. Next, NOX inhibitors (ML171 and apocynin), ROS scavenger (NAC), JNK inhibitor (SP600125), and caspase inhibitor (Z-VAD-FMK) were used to further investigate the underlying mechanisms of p20BAP31 on cell apoptosis. Finally, apoptosis-inducing factor (AIF) translocation from the mitochondria to the nuclei was verified by immunoblotting and immunofluorescence assay.
Results
We found that overexpression of p20BAP31 indeed induced apoptosis and had a much greater sensitivity in HCT116 cells. Furthermore, the overexpression of p20BAP31 inhibited cell proliferation by causing S phase arrest. Further study revealed that p20BAP31 reduced MMP, with a significant increase in ROS levels, accompanied by the activation of the MAPK signaling pathway. Importantly, the mechanistic investigation indicated that p20BAP31 induces mitochondrial-dependent apoptosis by activating the ROS/JNK signaling pathway and induces caspase-independent apoptosis by promoting the nuclear translocation of AIF.
Conclusions
p20BAP31 induced cell apoptosis via both the ROS/JNK mitochondrial pathway and AIF caspase-independent pathway. Compared with antitumor drugs that are susceptible to drug resistance, p20BAP31 has unique advantages for tumor therapy.

Abstract
Hexafluoropropylene oxide dimer acids (HFPO-DA) and hexafluoropropylene oxide trimer acids (HFPO-TA) are alternatives to perfluorooctanoic acid (PFOA). However, little information on the comparison of their toxicities is available. Here, zebrafish embryos were exposed to PFOA, HFPO-DA, and HFPO-TA with exposure concentrations of 5 and 500 μg/L. Behavioral abnormal, enzyme activities and gene expression profiles in zebrafish embryos were determined. Results showed that exposure to PFOA and its alternatives increased heart rates and inhibited locomotor activity of zebrafish embryos. Further, their exposures changed the enzyme activities (acetylcholinesterase and oxidative stress-related enzymes), ATP content, and expressions of genes related to hypothalamic-pituitary-thyroid (HPT) axis, apoptosis, and lipid metabolism. Comparison analyses found that PFOA, HFPO-TA, and HFPO-DA exposures induced different effects on the embryonic development of zebrafish, which indicates the different modes of action. The HFPO-DA exposure induced specific effects on the disorder of lipid metabolism, HPT axis, and neurodevelopment. The HFPO-TA exposure also induced different effects from the PFOA exposure, which focused on lipid metabolism. The current data shows that the HFPO-DA and HFPO-TA might not be safe alternatives to PFOA. This study provides a new understanding of the biological hazards of PFOA alternatives in aquatic organisms, which can guide their usage.

Mitochondrial tRNAGln 4394C>T Mutation May Contribute to the Clinical Expression of 1555A>G-Induced Deafness. Genes (Basel) 2022; 13:genes13101794. [PMID: 36292680 PMCID: PMC9602358 DOI: 10.3390/genes13101794] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 09/08/2022] [Accepted: 09/12/2022] [Indexed: 11/17/2022] Open
Abstract
The mitochondrial 1555A>G mutation plays a critical role in aminoglycoside-induced and non-syndromic hearing loss (AINSHL). Previous studies have suggested that mitochondrial secondary variants may modulate the clinical expression of m.1555A>G-induced deafness, but the molecular mechanism has remained largely undetermined. In this study, we investigated the contribution of a deafness-associated tRNAGln 4394C>T mutation to the clinical expression of the m.1555A>G mutation. Interestingly, a three-generation family with both the m.1555A>G and m.4394C>T mutations exhibited a higher penetrance of hearing loss than another family harboring only the m.1555A>G mutation. At the molecular level, the m.4394C>T mutation resides within a very conserved nucleotide of tRNAGln, which forms a new base-pairing (7T-66A) and may affect tRNA structure and function. Using trans-mitochondrial cybrid cells derived from three subjects with both the m.1555A>G and m.4394C>T mutations, three patients with only the m.1555A>G mutation and three control subjects without these primary mutations, we observed that cells with both the m.1555A>G and m.4394C>T mutations exhibited more severely impaired mitochondrial functions than those with only the m.1555A>G mutation. Furthermore, a marked decrease in mitochondrial RNA transcripts and respiratory chain enzymes was observed in cells harboring both the m.1555A>G and m.4394C>T mutations. Thus, our data suggest that the m.4394C>T mutation may play a synergistic role in the m.1555A>G mutation, enhancing mitochondrial dysfunctions and contributing to a high penetrance of hearing loss in families with both mtDNA pathogenic mutations.

Abstract
Methylglyoxal (MGO) is a reactive carbonyl species that can cause cellular damage and is closely related to kidney disease, especially diabetic nephropathy. The toxic effect of MGO (0.5, 1, and 2 mM) on human embryonic kidney (HEK293) cells and its underlying mechanism were explored in this study. Cell viability, apoptosis and the signaling pathways were measured with MTT, fluorescent staining and western blot experiments, the results showed that MGO could induce oxidative stress and cell inflammation, the level of reactive oxygen species (ROS) increased, and p38MAPK, JNK and NF-κB signaling pathways were activated. Meanwhile, MGO also induced DNA damage. The expression of DNA oxidative damage marker 8-hydroxy-2'-deoxyguanosine (8-OHdG) increased, the expression of double-strand break marker γH2AX increased significantly, and ATM/Chk2/p53 DNA damage response signaling pathway was activated. Furthermore, the expression of the receptor for advanced glycation end products (RAGE) also increased. Finally, mitochondrial membrane potential (MMP) decreased, fluorescence intensity of Hoechst33258 increased, and the protein expression ratio of Bax/Bcl-2 increased significantly after the treatment of MGO. These results demonstrated that MGO might induce HEK293 cells damage by regulating oxidative stress, inflammation, DNA damage, and cell apoptosis, which revealed the specific mechanism of MGO-induced damage to HEK293 cells.

Abstract
Introduction Septic cardiomyopathy is a common complication of sepsis with high morbidity and mortality, but lacks specific therapy. This study aimed to reveal the role of circTLK1 and its potential mechanisms in septic cardiomyopathy. Materials and Methods The in vitro and in vivo models of septic cardiomyopathy were established. Cell viability and apoptosis were detected by CCK8, TUNEL and flow cytometry, respectively. LDH, CK, SOD, MDA, ATP, 8‐OHdG, NAD+/NADH ratio, ROS level, mitochondrial membrane potential and cytochrome C distribution were evaluated using commercial kits. qRT‐PCR and western blotting were performed to detect RNA and protein levels. Mitochondrial DNA (mtDNA) copy number and transcription were assessed by quantitative PCR. Dual‐luciferase assay, RNA immunoprecipitation and co‐immunoprecipitation were performed to verify the interaction between circTLK1/PARP1 and miR‐17‐5p. Results CircTLK1, PARP1 and HMGB1 were up‐regulated in the in vitro and in vivo models of septic cardiomyopathy. CircTLK1 inhibition restrained LPS‐induced up‐regulation of PARP1 and HMGB1. Moreover, circTLK1 knockdown repressed sepsis‐induced mtDNA oxidative damage, mitochondrial dysfunction and consequent cardiomyocyte apoptosis by inhibiting PARP1/HMGB1 axis in vitro and in vivo. In addition, circTLK1 enhanced PARP1 expression via sponging miR‐17‐5p. Inhibition of miR‐17‐5p abolished the protective effects of circTLK1 silencing on oxidative mtDNA damage and cardiomyocyte apoptosis. Conclusion CircTLK1 sponged miR‐17‐5p to aggravate mtDNA oxidative damage, mitochondrial dysfunction and cardiomyocyte apoptosis via activating PARP1/HMGB1 axis during sepsis, indicating that circTLK1 may be a putative therapeutic target for septic cardiomyopathy.

Abstract
PURPOSE This study aimed to investigate the relationship between miR-141-3p and B lymphocyte-2 gene (Bcl2) gene and its biological behavior on colon cancer cell line SW480. METHODS qRT-PCR was used to detect the expression level of miR-141-3p in colon cancer tissues and adjacent tissues, as well as in colon cancer cell line and normal human colonic epithelial cell line FHC. MTT assay, wound assay, and Transwell demonstrated the effects of miR-141-3p on colon cancer proliferation, migration and invasion. Targetscan7.1 predictive software and dual luciferase reporter assays were used to detect the targeted regulation of miR-141-3p on the apoptosis-related gene Bcl2. MTT assay, wound assay, Transwell and flow cytometry were used to detect the effect of Bcl2 on miR-141-3p on colon cancer proliferation, migration, invasion and apoptosis. RESULTS Compared with adjacent tissues, the expression of miR-141-3p in colon cancer tissues was significantly down-regulated. Colon cancer patients with low expression of miR-141-3p had poorer prognosis. Compared with normal colonic epithelial cells, miR-141-3p expression was significantly down-regulated in colon cancer cell lines, and overexpression of miR-141-3p significantly attenuated the proliferation, migration and invasion of colon cancer cells. Knockdown of miR-141-3p significantly promoted the proliferation, migration and invasion of colon cancer cells. miR-141-3p targets the negative regulation of Bcl2. Knockdown of Bcl2 significantly attenuated the promotion of miR-141-3p inhibitor on proliferation, migration and invasion of colon cancer cells and inhibition of apoptosis. Knockdown of Bcl2 significantly enhanced the inhibition effect of miR-141-3p inhibitor on proliferation, migration and invasion of colon cancer cells. CONCLUSIONS In conclusion, miR-141-3p can inhibit the cancer by regulating Bcl2, and miR-141-3p has the potential to become a potential therapeutic target for colon cancer.

Abstract
Background Pyrazoles have attracted particular attention due to the diverse biological activities associated with this heterocyclic system, and some have been shown to be cytotoxic to several human cell lines. Several drugs currently on the market have this heterocycle as the key structural motif, and some have been approved for the treatment of different types of cancer. Results 4,4ʹ-(Arylmethylene)bis(1H-pyrazol-5-ols) derivatives 3a–q were synthetized by a three components reaction of 3-methyl-1-phenyl-5-pyrazolone (1) with various benzaldehydes 2 catalyzed by sodium acetate at room temperature. The structures of all synthesized compounds were characterized by physicochemical properties and spectral means (IR and NMR) and were evaluated for their radical scavenging activity by DPPH assay and tested in vitro on colorectal RKO carcinoma cells in order to determine their cytotoxic properties. All 4,4ʹ-(arylmethylene)bis(1H-pyrazol-5-ols) derivatives 3a–q were synthetized in high to excellent yield, and pure products were isolated by simple filtration. All compounds have good radical scavenging activity, and half of them are more active than ascorbic acid used as standard. Conclusion Several derivatives proved to be cytotoxic in the RKO cell line. In particular, compound 3i proved to be a very potent scavenger with an IC50 of 6.2 ± 0.6 µM and exhibited an IC50 of 9.9 ± 1.1 μM against RKO cell. Autophagy proteins were activated as a survival mechanism, whereas the predominant pathway of death was p53-mediated apoptosis.

Abstract
Background Natural products, especially those with high contents of phytochemicals, are promising alternative medicines owing to their antitumor properties and few side effects. In this study, the effects of a plant-based medicinal food (PBMF) composed of six medicinal and edible plants, namely, Coix seed, Lentinula edodes, Asparagus officinalis L., Houttuynia cordata, Dandelion, and Grifola frondosa, on gastric cancer and the underlying molecular mechanisms were investigated in vivo. Methods A subcutaneous xenograft model of gastric cancer was successfully established in nude mice inoculated with SGC-7901 cells. The tumor-bearing mice were separately underwent with particular diets supplemented with three doses of PBMF (43.22, 86.44, and 172.88 g/kg diet) for 30 days. Tumor volumes were recorded. Histopathological changes in and apoptosis of the xenografts were evaluated by hematoxylin and eosin staining and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining, respectively. Serum levels of TNF-α, MMP-2, and MMP-9 were detected by enzyme-linked immunosorbent assay. The mRNA expression levels of β-catenin, GSK-3β, E-cadherin, N-cadherin, MMP-2/9, Snail, Bax, Bcl-2, Caspase-3/9, and Cyclin D1 were evaluated via real-time quantitative polymerase chain reaction. The protein expression levels of GSK-3β, E-cadherin, N-cadherin, and Ki-67 were determined by immunohistochemistry staining. Results PBMF treatment efficiently suppressed neoplastic growth, induced apoptosis, and aggravated necrosis in the xenografts of SGC-7901 cells. PBMF treatment significantly decreased the serum levels of MMP-2 and MMP-9 and significantly increased that of TNF-α. Furthermore, PBMF treatment notably upregulated the mRNA expression levels of GSK-3β, E-cadherin, Bax, Caspase-3, and Caspase-9 but substantially downregulated those of β-catenin, N-cadherin, MMP-2, MMP-9, Snail, and Cyclin D1 in tumor tissues. The Bax/Bcl-2 ratio was upregulated at the mRNA level. Moreover, PBMF treatment remarkably increased the protein expression levels of GSK-3β and E-cadherin but notably reduced those of Ki-67 and N-cadherin in tumor tissues. Conclusions The PBMF concocted herein exerts anti-gastric cancer activities via epithelial–mesenchymal transition reversal, apoptosis induction, and proliferation inhibition. The underlying molecular mechanisms likely rely on suppressing the Wnt/β-catenin signaling pathway.

Almutairi FM, Ali AG, Abdelhamid AO, Alalawy AI, Bishr MK, Mohamed MS. The Identification of a Novel Unsymmetrical Azine as an Apoptosis Inducer in Colorectal Cancer. Anticancer Agents Med Chem 2021; 21:406-413. [PMID: 32838724 DOI: 10.2174/1871520620666200824095314] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 06/25/2020] [Accepted: 07/31/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Defects in the physiological mechanisms of apoptosis are one of the pivotal factors implicated in carcinogenesis. Thus, the development of novel compounds that target various apoptotic pathways has provided promising anticancer therapeutic opportunities. OBJECTIVE This study explores the cytotoxic effects of a novel unsymmetrical azine against specific cancer cell lines and investigates the mechanism of cytotoxicity. METHODS Molecular modeling was used to test the binding affinity of four new unsymmetrical azines to a model of an apoptosis inhibitor protein (XIAP). The compound with the highest binding affinity, C4, was further tested on different cell lines. Real-time Polymerase Chain Reaction (PCR) and Transmission Electron Microscope (TEM) were used to study apoptosis induction biochemically and morphologically. RESULTS In comparison to cisplatin as a control, the compound C4 exhibited notable cytotoxicity against all tested cancer cell lines, especially the human colorectal carcinoma cell line (HCT-116). Furthermore, C4-treated cells demonstrated marked overexpression of the pro-apoptotic proteins Bax and caspase-3 as well as the tumor suppressor p53. On the other hand, the expression of the anti-apoptotic protein Bcl-2 was inhibited. On TEM examination, C4-treated HCT-116 cells showed classical structural signs of apoptosis. CONCLUSION This study identifies a novel azine (C4), which induces remarkable cytotoxicity against the colorectal carcinoma cell line, mediated through apoptosis induction. These novel insights suggest C4 as a promising therapeutic agent in colorectal cancer.

Abstract
Identification of potent anticancer agents with high selectivity and low toxicity remains on the way to human health. Pyridazine featuring advantageous physicochemical properties and antitumor potential usually is regarded as a central core in numerous anticancer derivatives. There are several approved pyridazine-based drugs in the market and analogues currently going through different clinical phases or registration statuses, suggesting pyridazine as a promising drug-like scaffold. The current review is intended to provide a comprehensive and updated overview of pyridazine derivatives as potential anticancer agents. In particular, we focused on their structure-activity relationship (SAR) studies, design strategies, binding modes and biological activities in the hope of offering novel insights for further rational design of more active and less toxic anticancer drugs.

Ther Adv Chronic Dis 2020; 11:2040622320940185. [PMID: 32843954 PMCID: PMC7418478 DOI: 10.1177/2040622320940185] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Accepted: 06/15/2020] [Indexed: 12/19/2022] Open
Abstract
Introduction Idiopathic pulmonary fibrosis (IPF) is a progressive and irreversible interstitial pulmonary disease that has a poor prognosis. Scutellarein, which is extracted from the traditional Chinese medicine Erigeron breviscapus, is used to treat a variety of diseases; however, the use of scutellarein for the treatment of pulmonary fibrosis and the related mechanisms of action have not been fully explored. Methods This study was conducted using a well-established mouse model of pulmonary fibrosis induced by bleomycin (BLM). The antifibrotic effects of scutellarein on histopathologic manifestations and fibrotic marker expression levels were examined. The effects of scutellarein on fibroblast differentiation, proliferation, and apoptosis and on related signaling pathways were next investigated to demonstrate the underlying mechanisms. Results In the present study, we found that scutellarein alleviated BLM-induced pulmonary fibrosis, as indicated by histopathologic manifestations and the expression levels of fibrotic markers. Further data demonstrated that the ability of fibroblasts to differentiate into myofibroblasts was attenuated in scutellarein-treated mice model. In addition, we obtained in vitro evidence that scutellarein inhibited fibroblast-to-myofibroblast differentiation by repressing TGF-β/Smad signaling, inhibited cellular proliferation by repressing PI3K/Akt signaling, and increased apoptosis of fibroblasts by affecting Bax/Bcl2 signaling. Discussion In general, scutellarein might exert therapeutic effects on pulmonary fibrosis by altering the differentiation, proliferation, and apoptosis of fibroblasts. Although scutellarein has been demonstrated to be safe in mice, further studies are required to investigate the efficacy of scutellarein in patients with IPF.

Abstract
A novel biomacromolecule was prepared for a stabilizer sustained anticancer drug release system. Colloidal immunoglobulin G (IgG) nanoparticles (IgGNP) were synthesized and then characterized using FT-IR, SEM, zeta sizer, and AFM. Moreover, the formation of spherical shape IgGNP with an appropriate average size (144.56 ± 2 nm) and a narrow distribution for the drug release was confirmed. Also, the conjugation of oxaliplatin (OX) to IgGNP (OX@IgGNP) was demonstrated via the combination of spectroscopy and physical analyses. In this regard, the interaction was spantaneous with static quenching mechanism. OX caused well dispersity with no agglomeration on IgGNP with an average size of 142.31 ± 4 nm. Furthermore, the encapsulation efficiency (%EE) and drug loading (%DL) percentages were determined. Accordingly, the release behavior indicated that OX was sustained from IgGNP more than IgG (approximately 150 h) and the highest release amount of OX (100 %) was obtained at acidic medium (pH 5.5). Notably, the kinetic model was zero order and release mechanism followed by diffusion and Fick's model at neutral medium and combination of diffusion and swelling controlled and non-Fickian model at acidic medium. In addition, the anticancer effect of OX@IgGNP was evaluated on the human breast cancer cell lines, MCF-7 using MTT assay and DAPI staining that showed a remarkable efficacy, while the cytotoxicity in human fibroblast cell lines, HFFF2 has decreased. In this study, gene expression was investigated using real time PCR, which verified IgGNP induced programmed cell death in MCF-7 breast cancer cell more effectively than free OX. Subsequently, a novel nano scale biological macromolecule can be introduced as a sustained and prolonged anticancer drug release.

Abstract
New thiazolo[4,5-d]pyrimidine analogues were synthesized and biologically assessed in-vitro for their antineoplastic activity. The growth inhibitory effects of these compounds were assessed through the National Cancer Institute-United States of America (NCI-USA) anticancer screening program. Compound5(7-Chloro-3-(2,4-dimethoxyphenyl)-5-methylthiazolo[4,5-d]pyrimidine-2(3H)-thione) was found to have a potent and broad-spectrum cytotoxic action against NCI panel with GI50 (50% growth inhibition concentration) mean graph midpoint (MG-MID) = 2.88 µM. MTT assay was used to determine IC50 values of the most potent agent against HCT-116 colorectal carcinoma and WI-38 human lung fibroblast cell lines; 5.33 µM ± 0.69 and 21.69 µM ± 1.04, respectively. Flow cytometric analysis revealed that compound5triggered apoptosis and G2/M cell cycle arrest. The ability of compound5to inhibit CDK1 (Cyclin-Dependent Kinase 1)/Cyclin B complex was evaluated, and its IC50 value was 97 nM ± 2.33. Moreover, according to the gene expression analysis, compound5up-regulated p53, BAX, cytochrome c, caspases-3,-8 and-9 besides down-regulated Bcl-2. In conclusion, compound5exerted a potent pro-apoptotic activity through the activation of the intrinsic apoptotic pathway and arrested the cell cycle at the G2/M phase.

Abstract
The present study examined the apoptotic effects and the underlying mechanism of sappanchalcone, a major bioactive compound isolated from Caesalpinia sappan L. on human colon cancer cells. To achieve this, we used two different colon cancer cell lines, namely HCT116 (as wild-type p53 cells) and SW480 (as p53-mutant cells) cells. Our results illustrated that sappanchalcone treatment decreased the proliferation and further promoted apoptosis in HCT116 cells compared with the findings in SW480 cells. Sappanchalcone triggered phosphorylation of p53, which is involved in the activation of caspases and increased expression of Bax in HCT116 cells. Conversely, sappanchalcone-treated SW480 cells displayed no change in p53 phosphorylation or caspase activation. In addition, sappanchalcone further increased reactive oxygen species (ROS) levels and apoptosis-inducing factor (AIF) release in both HCT116 and SW480 cells. These data suggest that sappanchalcone induces apoptosis through caspase-dependent and caspases-independent mechanisms that were characterized by decreased Bcl-2 expression, mitochondrial targeting, and altered ROS production and AIF translocation to the nuclei.

Abstract
A new anticancer N-containing heterocyclic scaffold was designed and 30 pyridazino[1,6-b]quinazolinone derivatives were synthesized and characterized. Antiproliferation evaluation in vitro against four human cancer cell lines including SK-OV-3(ovarian cell), CNE-2(nasopharyngeal cell), MGC-803(gastric cell) and NCI-H460(lung cell) indicated that most of them exhibited potent anticancer activity and the IC50 value of the most potent compound lowered to sub-μM. DNA interaction assay indicated that compounds 4e, 4g, 6o, 6p, 8o can intercalate into DNA. Compounds 6 and 8 also demonstrated potent topoisomerase I (topo I) activity. Annexin V- FITC/propidium iodide dual staining assay and cell cycle analysis indicated that 2-(4-bromophenyl)-4-((3-(diethylamino)propyl)amino) -10H-pyridazino [1,6-b]quinazolin- 10-one (8p) could induce arrest cell cycle at G2 phase and apoptosis in MGC-803 cells in a dose-dependent manner. The in vivo antitumor efficiency of compound 8p was also evaluated on MGC-803 xenograft nude mice, and the relative tumor growth inhibition was up to 55.9% at a dose of 20 mg/kg per two days. The results suggested that pyridazino[1,6-b]-quinazolinones might serve as a promising novel scaffold for the development of new antitumor agents.

Abstract
BACKGROUND Lung cancer is one of the most prevalent malignancies and thus the development of novel therapeutic agents for managing lung cancer is imperative. Tetrandrine, a bis-benzyltetrahydroisoquinoline alkaloid isolated from Stephania tetrandra S. Moore, has been found to exert cytotoxic effects on cancerous cells. METHODS A series of 5-alkynyltetrandrine derivatives was synthesized via the Sonogashira cross-coupling reactions and evaluated as potential anti-tumor agents. The anti-tumor activities of 12 compounds on lung cancer cells (A549) were evaluated using the MTT method. The population of apoptotic cells was measured using a TUNEL assay. Real-time PCR quantified the gene expression levels of Bcl-2, Bax, survivin and caspase-3. The content of Cyt-C was detected using a Human Cyt-C ELISA kit. RESULTS Most of these compounds exhibited better activities than tetrandrine itself on A549 cells. Among them, compound 7 showed the highest cytotoxicity among the tested compounds against human lung adenocarcinoma A549 cells with an IC50 of 2.94 µM. Preliminary mechanistic studies indicated that compound 7 induced apoptosis of human lung cancer A549 cells and increased the level of the proapoptotic gene Bax, release of Cyt-C from mitochondria and activation of caspase-3 genes. CONCLUSION The results suggest that compound 7 exerts its antitumor activity against A549 cells through the induction of the intrinsic (mitochondrial) apoptotic pathway. These findings will contribute to the future design of more effective anti-tumor agents in lung cancer therapy.

Abstract
Hepatocellular carcinoma is the second most common cause of cancer death in the world and its incidence has dramatically increased worldwide in the past two decades. Syringic acid (SA) has been studied for its hepatoprotective, anti-inflammatory, immunomodulatory, free radical scavenging, and antioxidant activities. We aimed to evaluate the cytotoxic effect of SA against human hepatoma HepG2 cell line. Cytotoxicity was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. HepG2 cells were treated with SA at concentration ranges of 25, 50, and 100 µM for 24 h. Reactive oxygen species (ROS) expression was investigated by dichlorofluorescein staining assay. Morphological changes of SA-treated HepG2 cells were evaluated by acridine orange (AO) and ethidium bromide (EB) dual staining. Apoptotic marker gene expressions were evaluated by qPCR. SA treatment caused significant cytotoxicity and liberation of ROS in HepG2 cells. AO and EB staining showed membrane blebbing and distortion in SA-treated cells. Apoptotic markers such as caspases 3 and 9, cytochrome c, Apaf-1, Bax, and p53 gene expressions were significantly increased upon SA treatment indicating the possibility of apoptosis induction in HepG2 cells. This treatment also caused significant downregulation of Bcl-2 gene expression. SA has a cytotoxic effect on human HepG2 cell line, and this might be a promising agent in anticancer research.
