Development of fluorine-substituted NH2-biphenyl-diarylpyrimidines as highly potent non-nucleoside reverse transcriptase inhibitors: Boosting the safety and metabolic stability

Our recent studies for nonnucleoside reverse transcriptase inhibitors identified a highly potent compound JK-4b against WT HIV-1 (EC50 = 1.0 nmol/L), but the poor metabolic stability in human liver microsomes (t 1/2 = 14.6 min) and insufficient selectivity (SI = 2059) with high cytotoxicity (CC50 = 2.08 μmol/L) remained major issues associated with JK-4b. The present efforts were devoted to the introduction of fluorine into the biphenyl ring of JK-4b, leading to the discovery of a novel series of fluorine-substituted NH2-biphenyl-diarylpyrimidines with noticeable inhibitory activity toward WT HIV-1 strain (EC50 = 1.8-349 nmol/L). The best compound 5t in this collection (EC50 = 1.8 nmol/L, CC50 = 117 μmol/L) was 32-fold in selectivity (SI = 66,443) compared to JK-4b and showed remarkable potency toward clinically multiple mutant strains, such as L100I, K103N, E138K, and Y181C. The metabolic stability of 5t was also significantly improved (t 1/2 = 74.52 min), approximately 5-fold higher than JK-4b in human liver microsomes (t 1/2 = 14.6 min). Also, 5t possessed good stability in both human and monkey plasma. No significant in vitro inhibition effect toward CYP enzyme and hERG was observed. The single-dose acute toxicity test did not induce mice death or obvious pathological damage. These findings pave the way for further development of 5t as a drug candidate.

lncR-GAS5 upregulates the splicing factor SRSF10 to impair endothelial autophagy, leading to atherogenesis / 医学前沿

Long noncoding RNAs (lncRNAs) play a critical role in the regulation of atherosclerosis. Here, we investigated the role of the lncRNA growth arrest-specific 5 (lncR-GAS5) in atherogenesis. We found that the enforced expression of lncR-GAS5 contributed to the development of atherosclerosis, which presented as increased plaque size and reduced collagen content. Moreover, impaired autophagy was observed, as shown by a decreased LC3II/LC3I protein ratio and an elevated P62 level in lncR-GAS5-overexpressing human aortic endothelial cells. By contrast, lncR-GAS5 knockdown promoted autophagy. Moreover, serine/arginine-rich splicing factor 10 (SRSF10) knockdown increased the LC3II/LC3I ratio and decreased the P62 level, thus enhancing the formation of autophagic vacuoles, autolysosomes, and autophagosomes. Mechanistically, lncR-GAS5 regulated the downstream splicing factor SRSF10 to impair autophagy in the endothelium, which was reversed by the knockdown of SRSF10. Further results revealed that overexpression of the lncR-GAS5-targeted gene miR-193-5p promoted autophagy and autophagic vacuole accumulation by repressing its direct target gene, SRSF10. Notably, miR-193-5p overexpression decreased plaque size and increased collagen content. Altogether, these findings demonstrate that lncR-GAS5 partially contributes to atherogenesis and plaque instability by impairing endothelial autophagy. In conclusion, lncR-GAS5 overexpression arrested endothelial autophagy through the miR-193-5p/SRSF10 signaling pathway. Thus, miR-193-5p/SRSF10 may serve as a novel treatment target for atherosclerosis.

Research progress on damage and repair of blood vessels by central venous access devices / 中国实用护理杂志

The central venous access device (CVAD) is widely used in infusion of intravenous high nutrient solution, chemotherapy drugs, rapid infusion, blood transfusion, etc. CVAD is left in the patient′s blood vessels for a long time, although it has certain advantages in intravenous therapy, but also risks associated with it. In the past 20 years, many studies have focused on the mechanism of CVAD on vascular injury, trying to explore its mechanism from a different perspective at the microscopic level of pathophysiology. This article will review the three aspects of acute damage to the blood vessel caused by CVAD catheterization and chronic changes caused by indwelling catheters, analysis of the causes of vascular injury caused by CVAD catheterization, and research on preventing vascular injury caused by CVAD catheterization, aiming at providing reference for clinical intravenous therapy.

Up-regulation of glycolipid transfer protein by bicyclol causes spontaneous restriction of hepatitis C virus replication

Bicyclol is a synthetic drug for hepatoprotection in clinic since 2004. Preliminary clinical observations suggest that bicyclol might be active against hepatitis C virus (HCV) with unknown mechanism. Here, we showed that bicyclol significantly inhibited HCV replication and in hepatitis C patients. Using bicyclol as a probe, we identified glycolipid transfer protein (GLTP) to be a novel restrictive factor for HCV replication. The GLTP preferentially bound host vesicle-associated membrane protein-associated protein-A (VAP-A) in competition with the HCV NS5A, causing an interruption of the complex formation between VAP-A and HCV NS5A. As the formation of VAP-A/NS5A complex is essential for viral RNA replication, up-regulation of GLTP by bicyclol reduced the level of VAP-A/NS5A complex and thus inhibited HCV replication. Bicyclol also exhibited an inhibition on HCV variants resistant to direct-acting antiviral agents (DAAs) with an efficacy identical to that on wild type HCV. In combination with bicyclol, DAAs inhibited HCV replication in a synergistic fashion. GLTP appears to be a newly discovered host restrictive factor for HCV replication, Up-regulation of GLTP causes spontaneous restriction of HCV replication.

Acoustic response characteristics of posterior intralaminar nucleus of auditory thalamus in mice / 中华耳鼻咽喉头颈外科杂志

Objective@#To study the response characteristics of the posterior intralaminar nucleus (PIN) of auditory thalamus in VGluT2-Cre transgenic adult mice when exposed to white noise and 10K pure tone stimulation.@*Methods@#All adult male Vglut2-Cre mice (8-12 weeks) were used in this study between Oct, 2017 and Oct, 2018. Using the calcium signal fiber photometry method, optic fiber was employed to locate on PIN by injecting AAV-hSyn-DIO-GCaMP6m virus, and thereafter, the activity of the target cluster neurons during different acoustic stimuli was recorded. Matlab was used for data processing and statistical analysis.@*Results@#(1)In both white noise and 10 kHz pure tone as a continuous three-second stimulation, the peak amplitude of calcium signal activity generated in PIN by white noise was superior to that of pure tone, the statistic result showed significantly difference (n=6, t=2.404, P=0.037 1) . (2)In addition, when white noise and 10K pure tone played as consecutive 3 or 5 pips within three-second stimulation, the stimulus-following ability in a consecutive 3 pulses play within 3 seconds was far better than a consecutive 5 pips play within 3 seconds (in both white noise and 10 kHz pure tone), yet consecutive 3 pips play showed greater signal attenuation speed than that in consecutive 5 pips play, the statistic result showed significantly difference (n=6, t=2.748 P=0.033 4) .(3)Regardless of the intra-group comparisons between white noise and 10 kHz pure tone stimulation, PIN showed better signal response in a consecutive 3 pips play than consecutive 5 pips play or a continuous three-second stimulation. When came to the statistical analysis, the acoustic response degree of a continuous three-second stimulation was an intermediate between two others, both consecutive 3 or 5 pips play showed significantly difference.@*Conclusions@#The results suggest that under the same acoustic intensity, VGluT2-Cre transgenic adult mice′s PIN shows greater signal response in white noise than pure tone. PIN shows greater signal attenuation to repetition play of 10 kHz pure tone, which implies PIN shows stronger adaptation to 10 kHz pure tone than to white noise. Lastly, PIN is more responsive to a complex sound information (white noise) than to simple sound information (pure tone).

Objective To investigate clinical efficacy of N-acetylcysteine (NAC) in the adjuvant treatment of patients with acute exacerbation of asthma-chronic obstructive pulmonary disease overlap (ACO). Methods One hundred and forty-six patients with acute exacerbation of ACO admitted to department of respiratory and critical care medicine of Henan provincial people′s hospital from March 2016 to August 2018 were divided into control group and observation group according to random number table, with 73 patients in each group. The control group was given clinical treatment such as bronchodilator, inhaled glucocorticoid and low- flow oxygen inhalation during hospitalization, and inhalation of budesonide/formoterol fumarate powder combined with tiotropium was continued after discharge. The treatment lasted for 4 weeks. The observation group was added with NAC 600 mg, twice daily, totally for 4 weeks on the basis of the control group. Baseline data and duration of hospital stay were collected. Before and after treatment, blood routine, c-reactive protein (CRP), forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) and FEV1% pred were recorded. Clinical efficacy and adverse drug reaction were compared between the two groups. Results The white blood cell count, eosinophil count, neutrophil count, CRP, FEV1/FVC and FEV1% pred of two groups were significantly ameliorative after treatment compared with those before treatment, and the difference was statistically significant (P < 0.05). The white blood cell count, eosinophil count, neutrophil count and CRP after treatment in observation group were significantly lower than those in control group: (7.40 ± 1.12)×109/L vs. (8.34 ± 1.56) ×109/L, (0.30 ± 0.15) ×109/L vs. (0.42 ± 0.18) ×109/L, (3.76 ± 1.49) ×109/L vs. (4.58 ± 1.72) × 109/L, (5.33 ± 1.65) mg/L vs. (5.95 ± 1.74) mg/L, and the differences were statistically significant (P<0.05). There were no statistical differences in FEV1/FVC and FEV1%pred after treatment between observation group and control group (P > 0.05). The total effective rate after treatment in observation group was significantly higher than that in control group: 94.52% (69/73) vs. 82.19% (60/73), and the difference was statistically significant (P<0.05). During the treatment, duration of hospital stay in observation group was shorter than that in control group: (5.82 ± 2.29) d vs. (7.25 ± 3.05) d, and the difference was statistically significant (P<0.05). The incidence of adverse reactions in observation group was compared with control group: 10.96% (8/73) vs.5.48% (4/73), and the difference was not statistically significant (P > 0.05). Conclusions NAC has a significant effect in adjuvant treatment of acute exacerbation of ACO, which can significantly inhibit the level of inflammation and shorten the length of hospital stay.

The Expression and Relationship of CD68-Tumor-Associated Macrophages and Microvascular Density With the Prognosis of Patients With Laryngeal Squamous Cell Carcinoma

OBJECTIVES: We sought to identify the expression of CD68-tumor-associated macrophages (TAMs) and CD34-microvascular density (MVD) in laryngeal squamous cell carcinoma (LSCC), to study the relationship with clinical pathological parameters and to determine whether their expression is predictive of disease. METHODS: Pathologically confirmed 45 LSCC tissue and 20 peritumoral non-tumor tissue were examined. Immunohistochemical studies were used to detect the expression of CD68-TAMs and CD34-MVD. RESULTS: The positive expression rate of CD68 in LSCC tissue was 82% (37/45), which was higher than the 10% (2/20) expression rate of the peritumoral tissue (P<0.05). The CD34-MVD positive expression rate in the LSCC tissue was 26.5±6.4, which obviously higher than 12.2±4.0 expression rate of the peritumoral tissue (P<0.05). The positive expression rates of both CD68 and CD34-MVD were higher in the lymph node metastasis (LNM) positive group than in the LNM negative group. The expression of CD68 had positive correlation with CD34-MVD. The 5-year disease-free survival rate in the group with the low CD68 expression was significantly higher than that in the group with high CD68 expression (76% vs. 42%, respectively). CONCLUSION: The high expression of CD68-TAMs in LSCC and its positive correlation with CD34-MVD illustrates that both play an important role in promoting the metastasis and angiogenesis of this cancer. Their expression was also positively correlated with the prognoses of these patients, suggesting that they could be used as important prognostic markers for LSCC.

The expression rate of CD34-MVD in laryngeal squamous carcinoma tissue( 26.52 +/- 6.36 )is higher than that in peritumoral tissue (12.23 +/- 4.01) (P < 0.05). In lymph node metastasis group, the positive expression rates of CD68 and MMP-7 are higher than those in the group without lymph node metastasis. MMP-7 showed no correlation with cancer stage, and CD68 was related with cancer stage; CD68, MMP-7 and CD34- MVD have positive correlation.@*CONCLUSION@#The high level of expression of TAMs and MMP-7 in laryngeal cancer tissue and the positive correlation with MVD illustrate that both of the markers play important roles in promoting laryngeal squamous carcinoma tissue metastasis and angiogenesis, which can be used as important markers to evaluate the invasion and metastasis of laryngeal cancer.
