Abstract
Having continued our recent study on the synthesis and DNase I inhibition of several monosquaramides, two new chloro-substituted pyridine squaramates were synthesized and their structure was identified by X-ray. Their inhibitory properties towards deoxyribonuclease I (DNase I) and xanthine oxidase (XO) were evaluated in vitro. 3-(((6-Chloropyridin-3-yl)methyl)amino)-4-ethoxycyclobut-3-ene-1,2-dione (compound 3a) inhibited DNase I with an IC50 value of 43.82 ± 6.51 μM, thus standing out as one of the most potent small organic DNase I inhibitors tested to date. No cytotoxicity to human tumor cell lines (HL-60, MDA-MB-231 and MCF-7) was observed for the tested compounds. In order to investigate the drug-likeness of the squaramates, the ADME profile and pharmacokinetic properties were evaluated. Molecular docking was performed to reveal the binding mode of the studied compounds on DNase I.

Abstract
Herein we report an assessment of 24 1,2,3,4-tetrahydroisoquinoline derivatives for potential DNase I (deoxyribonuclease I) inhibitory properties in vitro. Four of them inhibited DNase I with IC50 values below 200 μM. The most potent was 1-(6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolin-1-yl)propan-2-one (2) (IC50 =134.35±11.38 μM) exhibiting slightly better IC50 value compared to three other active compounds, 2-[2-(4-fluorophenyl)-1,2,3,4-tetrahydroisoquinolin-1-yl]-1-phenylethan-1-one (15) (IC50 =147.51±14.87 μM), 2-[2-(4-fluorophenyl)-1,2,3,4-tetrahydroisoquinolin-1-yl]cyclohexan-1-one (18) (IC50 =149.07±2.98 μM) and 2-[6,7-dimethoxy-2-(p-tolyl)-1,2,3,4-tetrahydroisoquinolin-1-yl]cyclohexan-1-one (22) (IC50 =148.31±2.96 μM). Cytotoxicity assessment of the active DNase I inhibitors revealed a lack of toxic effects on the healthy cell lines MRC-5. Molecular docking and molecular dynamics simulations suggest that interactions with Glu 39, His 134, Asn 170, Tyr 211, Asp 251 and His 252 are an important factor for inhibitors affinity toward the DNase I. Observed interactions would be beneficial for the discovery of new active 1,2,3,4-tetrahydroisoquinoline-based inhibitors of DNase I, but might also encourage researchers to further explore and utilize potential therapeutic application of DNase I inhibitors, based on a versatile role of DNase I during apoptotic cell death.

DNaseI protects lipopolysaccharide-induced endometritis in mice by inhibiting neutrophil extracellular traps formation. Microb Pathog 2020; 150:104686. [PMID: 33309847 DOI: 10.1016/j.micpath.2020.104686] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Revised: 11/27/2020] [Accepted: 11/30/2020] [Indexed: 12/16/2022]
Abstract
Endometritis is an inflammatory of the inner lining of the uterus caused by bacterial infections that affect female reproductive health in humans and animals. Neutrophil extracellular traps (NETs) have the ability to resist infections that caused by pathogenic invasions. It has been proved that the formation of NETs is related to certain inflammatory diseases, such as mastitis and chronic obstructive pulmonary disease (COPD). However, there are sparse studies related to NETs and endometritis. In this study, we investigated the role of NETs in lipopolysaccharide (LPS)-induced acute endometritis in mice and evaluated the therapeutic efficiency of DNaseI. We established LPS-induced endometritis model in mice and found that the formation of NETs can be detected in the mice uterine tissues in vivo. In addition, DNaseI treatment can inhibit NETs construction in LPS-induced endometritis in mice. Moreover, myeloperoxidase (MPO) activity assay indicated that DNaseI treatment remarkably alleviated the inflammatory cell infiltrations. ELISA test indicated that the treatment of DNaseI significantly inhibited the expression of the proinflammatory cytokines TNF-α, and IL-1β. Also, DNaseI was found to increase proteins expression of the uterine tissue tight junctions and suppress LPS-induced NF-κB activation. All the results indicated that DNaseI effectively inhibits the formation of NETs by blocking the NF-κB signaling pathway and enhances the expression of tight junction proteins, consequently, alleviates inflammatory reactions in LPS-induced endometritis in mice.

Abstract
Aim: Eight new benzocyclobutane-2,5-diones (1a–1h) were synthesized, and their inhibitory properties against bovine pancreatic DNase I were examined in vitro. Methods & results: Compounds 1a–1h were synthesized using photocycloaddition of duroquinone with various phenyl-substituted ethylenes in the presence of 18W compact fluorescent lamp (visible light). Two compounds, 1,3,4,6-tetramethyl-7-phenylbicyclo[4.2.0]oct-3-ene-2,5-dione (1a) and 1,3,4,6-tetramethyl-7-p-tolylbicyclo[4.2.0]oct-3-ene-2,5-dione (1b) inhibited DNase I in a noncompetitive manner with IC50 values below 150 μM and showed to be more potent DNase I inhibitors than crystal violet, used as a positive control. In order to analyze potential binding sites for the studied compounds with DNase I, molecular docking study was performed. Conclusion: The studied benzocyclobutane-2,5-diones offer a good starting point for a design of new DNase I inhibitors.

Increased formation of neutrophil extracellular traps is associated with gut leakage in patients with type 1 but not type 2 diabetes. J Diabetes 2019; 11:665-673.

Abstract
BACKGROUND The aim of this study was to investigate the association of the formation of neutrophil extracellular traps (NETs) with gut leakage in type 1 (T1D) and type 2 diabetes (T2D). METHODS In all, 105 subjects (56 T1D, 49 T2D) were included in the study. Eight biomarkers of NET formation and gut leakage (ie, protein arginine deiminase type 4 [PAD4], neutrophil elastase [NE], proteinase 3 [PR3], complement 5a [C5a], α1 -antitrypsin [AAT], DNase I, zonulin, and lipopolysaccharide [LPS]) were measured in serum samples by ELISA. Neutrophils were isolated and stimulated by phorbol myristate acetate to form NETs in vitro. Neutrophil intracellular contents were then collected and used as antigens to detect anti-neutrophil cytoplasmic antibodies (ANCA) in the serum. RESULTS There was an increase in NET-associated proteins (PAD4, NE, PR3, C5a, AAT and DNase I) in new-onset T1D patients but not in those with T2D. Of PAD4, NE, and PR3, PAD4 was found to be the most sensitive biomarker for the diagnosis of T1D. Furthermore, circulating levels of zonulin and LPS were not only increased, but were also strongly correlated with NET formation and ANCA generation in T1D patients. CONCLUSIONS This study provides evidence that increased formation of NETs, particularly PAD4, is closely associated with gut leakage in T1D but not T2D, and suggests that microorganisms and the release of neutrophil cytoplasmic antigen during the formation of NETs may be involved in the pathogenesis of T1D.

Abstract
Diabetic kidney disease (DKD) is the leading cause of end-stage kidney disease, and satisfactory therapeutic strategies have not yet been established. The Shen-Yan-Fang-Shuai Formula (SYFSF) is a traditional Chinese formula composed of Astragali radix, Radixangelicae sinensis, Rheum officinale Baill, and four other herbs. It has been widely used as an effective treatment for DKD patients in China. However, little is known about the molecular mechanisms underlying SYFSF's renoprotection. In this study, we compared the protective effect of SYFSF to irbesartan on the histology and renal cells in type 2 DKD rat model and high-glucose (HG) cultured mesangial cells, respectively. We found that SYFSF could significantly decrease urinary albumin, cholesterol, and triglyceride. And a decrease in serum creatinine was also found in SYFSF-treated group compared with irbesartan-treated rats. In addition, SYFSF inhibited the interstitial expansion and glomerulosclerosis in diabetic rats. Notably, SYFSF markedly downregulated the expression of MCP-1, TGF-β1, collagen IV, and fibronectin in diabetic rat models and HG-induced mesangial cell models. The renoprotection was closely associated with a reduced expression of TNF-α and phosphorylated NF-κBp65. Our study suggests that SYFSF may ameliorate diabetic kidney injury. The observed renoprotection is probably attributable to an inhibition of inflammatory response and extracellular matrix (ECM) accumulation mediated by TNF-α/NF-κBp65 signaling pathway.

We herein describe an innovative method for a universal fluorescence turn-on enzyme assay, which relies on the target enzyme-triggered DNA polymerase activity. In the first target recognition step, the target enzyme is designed to destabilize detection probe derived from an aptamer specific to DNA polymerase containing the overhang sequence and the complementary blocker DNA, which consequently leads to the recovery of DNA polymerase activity inhibited by the detection probe. This target-triggered polymerase activity is monitored in the second signal transduction step based on primer extension reaction coupled with TaqMan probe. Utilizing this design principle, we have successfully detected the activities of two model enzymes, exonuclease I and uracil DNA glycosylase with high sensitivity and selectivity. Since this strategy is composed of separated target recognition and signal transduction modules, it could be universally employed for the sensitive determination of numerous different target enzymes by simply redesigning the overhang sequence of detection probe, while keeping TaqMan probe-based signal transduction module as a universal signaling tool.

Abstract
Deoxyribonuclease I (DNase I) is an endonuclease responsible for the destruction of chromatin during apoptosis. However, its role in diabetes remains unclear. The aim of the current study was to investigate the role of DNase I combined with high glucose levels in β-cell apoptosis. Human samples were collected and the DNase I activity was examined. High glucose-cultured INS-1 cells were transfected with DNase I small interfering RNA (siRNA) and the cell apoptosis was examined by western blotting and flow cytometry. Cell viability was analyzed by the Cell Counting Kit-8 assay. Cell apoptosis resulting from 50 mU/μl DNase I was also observed by flow cytometry, terminal deoxynucleotidyl transferase dUTP nick-end labeling stain and western blotting. Compared with healthy controls, the serum DNase I activity of patients with diabetes was significantly increased (P<0.05). In addition, DNase I expression was observed to be significantly increased in human pancreatic tissues. The addition of high glucose upregulated the cell apoptotic rate, whereas DNase I knockdown significantly reduced apoptosis in cells treated with high glucose. In addition, the western blotting results indicated that caspase-3 was increased subsequent to treatment of cells with 30 mM high glucose, however, this increase can be reversed by transfection with DNase I siRNA (P<0.05). Compared with cells cultured in normal conditions and high glucose, 50 mU/μl DNase I was able to significantly increase the cell apoptotic rate and level of caspase-3. DNase I activity was observed to be increased in type 2 diabetes, and high glucose combined with increased DNase I is suggested to aggravate β-cell apoptosis.

Abstract
Objective Inflammation and fibrosis are essential promoters in the pathogenesis of diabetic nephropathy (DN) in type 2 diabetes. The present study examined the anti-inflammation and anti-fibrosis effect of Tangshen Formula (TSF), a traditional Chinese medicine, on DN. Research Design and Methods Protective role of TSF in DN was examined in a rat model of type 2 DN that was established by high-fat diet-fed and low-dose-streptozotocin injection. TSF was suspended in 0.5% CMC-Na solution and delivered by oral gavage at a dosage of 1.67g/Kg body weight/day. The therapeutic effects and mechanisms of TSF on diabetic kidney injury were examined. Results We found that TSF treatment for 20 weeks attenuated DN by significantly inhibiting urinary excretion of albumin and renal histological injuries. These beneficial effects were associated with an inactivation of NF-κB signaling, thereby blocking the upregulation of pro-inflammatory cytokines (IL-1β, TNFα), chemokine (MCP-1), and macrophage infiltration in the TSF-treated rats with type 2 DN. In addition, TSF treatment also inactivated TGF-β/Smad3 signaling and therefore suppressed renal fibrosis including expressions of fibronectin, collagen I, and collagen IV. Further studies revealed that the inhibitory effect of TSF on TGF-β/Smad3 and NF-κB signaling in DN was associated with inhibition of Smurf2-dependent ubiquitin degradation of Smad7. Conclusions The present study reveals that TSF has therapeutic potential for type 2 DN in rats. Blockade of NF-κB-driven renal inflammation and TGF-β/Smad3-mediated renal fibrosis by preventing the Smurf2-mediated Smad7 degradation pathway may be mechanisms through which TSF inhibits type 2 DN.

Abstract
Diabetes is associated with dire peripheral sequelae including foot ulcers and amputations. A recent article by Wong et al. demystifies this connection by demonstrating that the neutrophil defense mechanism of extruding decondensed chromatin, termed NETosis, mediates delayed wound healing in diabetes and provides a therapeutic strategy for this indication.

Abstract
Emerging evidence suggests a potential role of neutrophil extracellular traps (NETs) in linking sterile inflammation and thrombosis. We hypothesized that NETs would be induced during myocardial ischemia-reperfusion (I/R), and NET-mediated microthrombosis may contribute to myocardial "no-reflow". Male Wistar rats were randomly divided into I/R control, DNase (DNase I, 20 μg/rat), recombinant tissue-type plasminogen activator (rt-PA, 420 μg/rat), DNase + rt-PA, and sham control groups after 45-min myocardial ischemia. In situ NET formation, the anatomic "no re-flow" area, and infarct size were evaluated immediately after 3 h of reperfusion. Long-term left ventricular (LV) functional and histological analyses were performed 45 days after operation. Compared with the I/R controls, the DNase + rt-PA group exhibited reduced NET density [8.38 ± 1.98 vs. 26.86 ± 3.07 (per 200 × field), P < 0.001] and "no-flow" area (15.22 ± 0.06 vs. 34.6 ± 0.05%, P < 0.05) in the ischemic region, as well as reduced infarct size (38.39 ± 0.05 vs. 71.00 ± 0.03%, P < 0.001). Additionally, compared with the I/R controls, DNase + rt-PA treatment significantly ameliorated I/R injury-induced LV remodeling (LV ejection fraction: 64.22 ± 3.37 vs. 33.81 ± 2.98%, P < 0.05; LV maximal slope of the LV systolic pressure increment: 3,785 ± 216 vs. 2,596 ± 299 mmHg/s, P < 0.05). The beneficial effect was not observed in rats treated with DNase I or rt-PA alone. Our study provides evidence for the existence of NETs in I/R-challenged myocardium and confirms the long-term benefit of a novel DNase-based reperfusion strategy (DNase I + rt-PA), which might be a promising option for the treatment of myocardial I/R injury and coronary no-reflow.
