Effect of Morinda citrifolia fruit extract and its iridoid glycosides on blood fluidity

The aim of this study was to investigate the effect of Morinda citrifolia fruit on blood fluidity. M. citrifolia fruit extract (MCF-ext) was investigated for its influence on blood aggregation and fibrinolysis. MCF-ext inhibited polybrene-induced erythrocyte aggregation and thrombin activity. The fibrinolytic activity of MCF-ext, in the euglobulin lysis time test and fibrin plate assay, is reported here for the first time. One of the active compounds was an iridoid glycoside, asperulosidic acid. The results indicated that MCF-ext is a potentially useful health food which is capable of improving blood flow and preventing lifestyle-related diseases.     

In vitro cytotoxicity,cell cycle arrest,and antioxidation studies of ruthenium(II) complex [Ru(dmb)2(AHPIP)](ClO4)2

A new Ru(II) complex [Ru(dmb)₂(AHPIP)](ClO₄)₂ (Ru1) was synthesized and characterized by elemental analysis, electrospray ionization mass spectra, and ¹H NMR and ¹³C NMR. The cytotoxicity in vitro toward BEL-7402, HeLa, MCF-7, and MG-63 cells was studied by MTT method. The complex shows moderate cytotoxic activity and the IC₅₀ values are 20.2 (±1.6), 16.8 (±1.3), 39.9 (±2.5), and 46.7 (±2.0) μM toward BEL-7402, HeLa, MCF-7, and MG-63 cell lines, respectively. Apoptosis was studied by acridine orange/ethidium bromide staining and flow cytometry. The cellular uptake showed that the complex can enter into the cytoplasm. The cell cycle arrest showed that Ru1 inhibits the proliferation of BEL-7402 cells in the G0/G1 phase. In addition, the antioxidant activity of the complex against hydroxyl radical (^·OH) was also investigated.     

Synthesis and biological evaluation of novel quinolin-2(1H)-one derivatives as potential antimicrobial agents

A series of novel quinolin-2(1H)-one derivatives were synthesized and characterized by IR, ¹H NMR, ¹³C NMR, and MS spectral data. All the new compounds were screened for their antimicrobial activities against six trains of bacteria and five fungi in vitro by twofold serial dilution technique. The bioactive assay showed that most of the compounds exhibited moderate to good antimicrobial activities in comparison with the streptomycin, especially, compound 6a, the fluoro-substituted aromatic amide derivative, showed good antibacterial activities against B.proteus and P.aeruginosa with minimal inhibitory concentration value of 32 and 16 μg/ml, respectively.     

Studies on the inhibitory models of pyrazoline derivatives as EGFR kinase inhibitors by 3D-QSAR and molecular docking

The development of EGFR kinase inhibitors attracts much attention of research for treating of cancer in recent years. In this work, based on a dataset composed of 46 EGFR kinase inhibitors, the combination of three-dimensional quantitative structure–activity relationship (3D-QSAR), molecular docking was applied to reveal structural characteristics impacting the inhibitory activity of EGFR, and to provide a better understanding of the binding modes between inhibitors and EGFR kinase. 3D-QSAR models of pyrazoline derivatives were established to reveal how steric, electrostatic, hydrophobic, and H-bond acceptor interactions contribute to inhibitors’ bioactivities, which were unanimous in the docking results. Furthermore, based on the most active compound, several new molecules with high inhibitory activity were obtained.     

Design,synthesis, and evaluation of novel 1-methyl-3-substituted quinazoline-2,4-dione derivatives as antimicrobial agents

A series of novel 1-methyl-3-substituted quinazoline-2,4-dione derivatives was designed, synthesized, and evaluated for their antimicrobial activities against six strains of bacteria and five fungi in vitro. The synthesized compounds were characterized by spectral methods. The bioactive assays showed that most of the compounds exhibited moderate antimicrobial activities against the tested strains.

Bone marrow enriched graft,modified by self-assembly peptide,repairs critically-sized femur defects in goats

Purpose

This study focuses on nanoscale self–assembly peptides (SAP) modified demineralized bone matrix (DBM) which provided a more effective osteogenesis and regeneration for critically-sized femur defects in goats using the selective cell retention (SCR) strategy.

Methods

RADA16–I peptide was used to modify DBM and formed a composite scaffold (SAP/DBM). The morphological change and dynamic expression of osteogenic genes of mesenchymal stem cells (MSCs) derived from marrow in SAP/DBM was observed. The cells and factors in bone marrow were enriched into SAP/DBM by technology of selective cells retension (SCR). The construct was transplanted into 20-mm femur defects in goats and their osteogenesis was evaluated.

Results

The SAP/DBM scaffold formed a three-dimensional interweaving nanofiber in pores of DBM. MSCs exhibited better morphology in SAP/DBM than that in only DBM, and the levels of expression of ALP ,OCN and Runx2 gene in SAP/DBM samples was significantly higher than that of DBM at 14 days in vitro (P?P?Conclusion Our study may not only have a significant impact on the construction method of tissue engineering but also provide a viable, simple and effective method for clinical bone construction.
