Babu, Sukumaran Santhosh; Praveen, Vakayil K.; Kartha, Kalathil K.; Mahesh, Sankarapillai; Ajayaghosh, Ayyappanpillai published the artcile< Effect of the Bulkiness of the End Functional Amide Groups on the Optical, Gelation, and Morphological Properties of Oligo(p-phenylenevinylene) π-Gelators>, Formula: C19H34O2, the main research area is bulkiness amide group optical gelation morphol oligophenylenevinylene gelator; gels; hydrogen bonds; phenylenevinylenes; pi interactions; self-assembly.

Herein, we describe the role of end functional groups in the self-assembly of amide-functionalized oligo(p-phenylenevinylene) (OPV) gelators with different end-groups. The interplay between hydrogen-bonding and π-stacking interactions was controlled by the bulkiness of the end functional groups, thereby resulting in aggregates of different types, which led to the gelation of a wide range of solvents. The variable-temperature UV/Vis absorption and fluorescence spectroscopic features of gelators with small end-groups revealed the formation of 1D H-type aggregates in CHCl3. However, under fast cooling in toluene, 1D H-type aggregates were formed, whereas slow cooling resulted in 2D H-type aggregates. OPV amide with bulky dendritic end-group formed hydrogen-bonded random aggregates in toluene and a morphol. transition from vesicles into fibrous aggregates was observed in THF. Interestingly, the presence of bulky end-group enhanced fluorescence in the xerogel state and aggregation in polar solvents. The difference between the aggregation properties of OPV amides with small and bulky end-groups allowed the preparation of self-assembled structures with distinct morphol. and optical features.

Huang, Danyun; Li, Zhijun; Chen, Yue; Fan, Yan; Yu, Tao published the artcile< Paeoniflorin reduces the inflammatory response of THP-1 cells by up-regulating microRNA-124 - Paeoniflorin reduces the inflammatory response of THP-1 cells through microRNA-124>, Reference of 112-63-0, the main research area is paeoniflorin THP cell microRNA inflammatory response; Apoptosis; Paeoniflorin; Proliferation; THP-1 cells; miRNA-124.

The activation of macrophages and the release of inflammatory cytokines are the main reasons for the progress of systemic lupus erythematosus (SLE). MicroRNA (miRNA)-124 is involved in the regulation of macrophages and is a key regulator of inflammation and immunity. To explore whether paeoniflorin (PF) regulates the biol. functions of macrophages depends on miR-124. RT-PCR, WB, ELISA, CCK-8 and flow cytometry were used to evaluate that PF regulated the biol. functions of THP-1 cells through miR-124. PF significantly inhibited the proliferation while promotes the apoptosis of THP-1 cells, and inhibited the release of IL-6, TNF-α and IL-1β in THP-1 cells. RT-PCR results shown that PF up-regulated the expression of miR-124 in THP-1 cells. Functional recovery experiments showed that compared with the LPS + mimic-NC group, LPS + miR-124 mimic significantly inhibited the proliferation and the release of IL-6, TNF-α and IL-1β, but promoted the apoptosis of THP-1 cells. In addition, compared with the LPS + PF + inhibitor-NC group, LPS + PF + miR-124 inhibitor significantly promoted the proliferation and the release of IL-6, TNF-α and IL-1β, but inhibited the apoptosis of THP-1 cells. By down-regulating miR-124, PF inhibits the proliferation and inflammation of THP-1 cells, and promotes the apoptosis of THP-1 cells.

Glioblastoma (GBM) represents one of the deadliest tumors owing to a lack of effective treatments. The adverse outcomes are worsened by high rates of treatment discontinuation, caused by the severe side effects of temozolomide (TMZ), the reference treatment. Therefore, understanding TMZ′s effects on GBM and healthy brain tissue could reveal new approaches to address chemotherapy side effects. In this context, we have previously demonstrated the membrane lipidome is highly cell type-specific and very sensitive to pathophysiol. states. However, little remains known as to how membrane lipids participate in GBM onset and progression. Hence, we employed an ex vivo model to assess the impact of TMZ treatment on healthy and GBM lipidome, which was established through imaging mass spectrometry techniques. This approach revealed that bioactive lipid metabolic hubs (phosphatidylinositol and phosphatidylethanolamine plasmalogen species) were altered in healthy brain tissue treated with TMZ. To better understand these changes, we interrogated RNA expression and DNA methylation datasets of the Cancer Genome Atlas database. The results enabled GBM subtypes and patient survival to be linked with the expression of enzymes accounting for the observed lipidome, thus proving that exploring the lipid changes could reveal promising therapeutic approaches for GBM, and ways to ameliorate TMZ side effects.

Wu, Yibing; Canturk, Belgin; Jo, Hyunil; Ma, Chunlong; Gianti, Eleonora; Klein, Michael L.; Pinto, Lawrence H.; Lamb, Robert A.; Fiorin, Giacomo; Wang, Jun; DeGrado, William F. published the artcile< Flipping in the Pore: Discovery of Dual Inhibitors That Bind in Different Orientations to the Wild-Type versus the Amantadine-Resistant S31N Mutant of the Influenza A Virus M2 Proton Channel>, Electric Literature of 112-63-0, the main research area is amantadine antiviral influenza virus proton channel inhibitor.

Influenza virus infections lead to numerous deaths and millions of hospitalizations each year. One challenge facing anti-influenza drug development is the heterogeneity of the circulating influenza viruses, which comprise several strains with variable susceptibility to antiviral drugs. For example, the wild-type (WT) influenza A viruses, such as the seasonal H1N1, tend to be sensitive to antiviral drugs, amantadine and rimantadine, while the S31N mutant viruses, such as the pandemic 2009 H1N1 (H1N1pdm09) and seasonal H3N2, are resistant to this class of drugs. Thus, drugs targeting both WT and the S31N mutant are highly desired. The authors report the design of a novel class of dual inhibitors along with their ion channel blockage and antiviral activities. The potency of the most active compound 11 in inhibiting WT and the S31N mutant influenza viruses is comparable with that of amantadine in inhibiting WT influenza virus. Solution NMR studies and mol. dynamics (MD) simulations of drug-M2 interactions supported the design hypothesis: namely, the dual inhibitor binds in the WT M2 channel with an aromatic group facing down toward the C-terminus, while the same drug binds in the S31N M2 channel with its aromatic group facing up toward the N-terminus. The flip-flop mode of drug binding correlates with the structure-activity relationship (SAR) and has paved the way for the next round of rational design of broad-spectrum antiviral drugs.

Glioblastoma (GBM) is the most common and highly lethal type of brain tumor, with poor survival despite advances in understanding its complexity. After current standard therapeutic treatment, including tumor resection, radiotherapy and concomitant chemotherapy with temozolomide, the median overall survival of patients with this type of tumor is less than 15 mo. Thus, there is an urgent need for new insights into GBM mol. characteristics and progress in targeted therapy in order to improve clin. outcomes. The literature data revealed that a number of different signaling pathways are dysregulated in GBM. In this review, we intended to summarize and discuss current literature data and therapeutic modalities focused on targeting dysregulated signaling pathways in GBM. A better understanding of opportunities for targeting signaling pathways that influences malignant behavior of GBM cells might open the way for the development of novel GBM-targeted therapies.

The transition between quiescence and activation in neural stem and progenitor cells (NSPCs) is coupled with reversible changes in energy metabolism with key implications for lifelong NSPC self-renewal and neurogenesis. How this metabolic plasticity is ensured between NSPC activity states is unclear. We find that a state-specific rewiring of the mitochondrial proteome by the i-AAA peptidase YME1L is required to preserve NSPC self-renewal. YME1L controls the abundance of numerous mitochondrial substrates in quiescent NSPCs, and its deletion activates a differentiation program characterized by broad metabolic changes causing the irreversible shift away from a fatty-acid-oxidation-dependent state. Conditional Yme1l deletion in adult NSPCs in vivo results in defective self-renewal and premature differentiation, ultimately leading to NSPC pool depletion. Our results disclose an important role for YME1L in coordinating the switch between metabolic states of NSPCs and suggest that NSPC fate is regulated by compartmentalized changes in protein network dynamics.

In this study, we investigated anti-cancer and antimicrobial activity of Aegle marmelos leaf extracts and their chem. profile characterized by gas chromatog. coupled mass spectrometry (GC-MS). A. marmelos leaves were extracted with acetone, methanol, ethanol, and chloroform. Presence of phenolic compounds was identified in these extracts by qual. anal. All the extracts were subjected for anti-bacterial activity against the different strains of bacteria (Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Bacillus ariyabattai, Bacillus megaterium, Pseudomonas putida, Klebsiella pneumonia, Serratia marcescens, and Escherichia coli). It is noteworthy that acetone extract elicited maximum growth inhibition on Serratia marcescens. Based on profound anti bacterial activity, acetone and methanol extract of A. marmelos were checked for cytotoxicity against MDA-MB-231, HEp-2 and vero cells. MDA-MB-231 cells were more sensitive to acetone extract of A. marmelos with an IC50 value of 79.62 μg/mL where as HEp-2 cells are more sensitive to methanol extract of A. marmelos with an IC50 value of 47.08 μg/mL. Vero cells withstand 24 h treatment of both extract, and it is evidenced that both acetone and methanol extract of A. marmelos exhibited chemo sensitive property towards cancer cells. GCMS anal. was performed to characterize the active principles of acetone and methanol extracts of A. marmelos. GC MS data revealed the presence of ten major components. Overall, both acetone and methanol extract of A. marmelos found to be promising anti antibacterial and anti-cancer agent however the active principle of these should be isolated and characterized before reaching a concrete scientific conclusion.
