The purpose of the recent research was to assess the chemical characterization and antioxidant, cytotoxic, antibacterial, and antifungal effects of Allium Saralicum R.M. Fritsch leaves. After identification of the plant, its ethanolic extract was obtained using Soxhlet extractor without leaving any chemicals in it. Gas chromatography-mass spectrometry (GC/MS) was performed to detect the percentage, retention index, and time of A. Saralicum compounds. Agar diffusion tests were applied to determine the antibacterial and antifungal characteristics. In agar disk diffusion test, dimethyl sulfoxide (DMSO) was used as negative control, while antibacterial (Difloxacin, Chloramphenicol, Streptomycin, Gentamicin, Oxytetracycline, Ampicillin, and Amikacin) and antifungal (Fluconazole, Itraconazole, Miconazole, Amphotericin B, and Nystatin) antibiotics were used as positive controls. Macro broth tube test was run to determine Minimum Inhibitory Concentration (MIC). The findings indicated that linolenic acid, methyl ester was the most frequent constituent found in A. Saralicum. Indeed, A. Saralicum showed higher antibacterial and antifungal properties than all standard antibiotics (p ?.01). Also, A. Saralicum prevented the growth of all bacteria and fungi at 15?125 mg/mL concentrations and destroyed them at 15?250 mg/mL concentrations (p ?.01). DPPH free radical scavenging test was carried out to examine the antioxidant effect, which indicated similar antioxidant activity with butylated hydroxy toluene (BHT) as a positive control. The synthesized ethanolic extract had great cell viability dose-dependently and demonstrated this method was nontoxic for synthesizing A. Saralicum. In conclusion, the findings showed the useful antioxidant, non-cytotoxic, antibacterial, and antifungal effects of A. Saralicum ethanolic extract.

The basic hexapeptide antagonist [Arg6, D-Trp7,9, MePhe8]substance P (6-11) was degraded in acid and alkaline media. In acid solution, only one degradation product is found whereas in alkaline solution at least six products are formed. These compounds were analytically characterized and structurally identified by reversed-phase high-performance liquid chromatography, capillary electrophoresis, liquid chromatography/mass spectrometry, fast atom bombardment tandem mass spectrometry, optical rotation analysis, and chiral gas chromatography. The product formed in acidic solution is the terminally deamidated antagonist [Arg6, D-Trp7,9, MePhe8]substance P (6-11); this product was also found in alkaline degradation mixtures. Other important degradation products originate from racemization of the amino acid residue L-Met, formation of ornithine from Arg, and the oxidation of Met to its sulfoxide form.

Bush tea (Athrixia phylicoides DC.) is a popular medicinal South African indigenous plant and it has been used for many decades as a health beverage and medicine. The objective of the study was to profile metabolites for assessment of quality of bush tea (A. phylicoides DC.) subjected to different pruning levels. Treatments consisted of untreated control, top-branch pruning, middle pruning, and basal pruning arranged in a randomized complete block design (RCBD) using 10 single trees as replications. The liquid chromatography quadrupole time-of-flight mass spectrometry (LC?QTOF?MS) was carried out to annotate the bush tea metabolites present in bush tea. Orthogonal partial least square-discriminatory analysis (OPLS-DA) from 1H nuclear magnetic resonance (NMR) revealed a separation between the basal, middle, top pruning, and the unpruned bush tea plants. The pruned (top) and unpruned tea plants, exhibited higher levels of metabolites than the basal and middle pruned. Pruning bush tea showed a significant effect on accumulation of secondary metabolites and thus could enhance bush tea quality. The study successfully annotated 28 metabolites (compounds), which elucidated canonical differences in pruning treatment of bush tea, as validated through multivariate analysis. Top pruning (apically pruned) resulted in improved metabolite accumulation than other treatment and can be recommended in bush tea cultivation. Future studies to enhance vegetative enhancement after pruning will be evaluated.

This paper reports the synthesis of polymetallic complexes in which two or three Group 4 metals are linked to a benzene core through oxo groups. Four methods have been evaluated for the synthesis of such derivatives: from the appropriated alcohol with (a) methyl complexes via methane elimination, (b) chloride compounds in the presence of a Lewis base, or (c) a zirconium hydride, and (d) from the lithium salt of the alcohol and chloride complexes. Method a has been used for the synthesis of bimetallic and trimetallic (pentamethylcyclopentadienyl)titanium(IV) complexes [{Ti(C5Me5)Cl2}2 {mu-1,4-O(C6H2XY)O-}] (X=Y=H (1); X = H, Y = Me (2); X=Y=Me (3)), [{Ti(C5Me5)Me2} 2{mu-1,4-O(C6H2Me2)O-}] (4), and [{Ti(C5Me5)X2}3 (mu3-1,3,5-C6H3O3-)] (X = Cl (7), Me (8)) from the corresponding hydroquinones 1,4-HO (2,3-C6H2XY)OH (X = Y = H, Me; X = H, Y = Me) or 1,3,5-trihydroxibenzene and [Ti(C5Me5) Cl2Me] or [Ti(C5Me5)Me3], respectively. Bis(cyclopentadienyl)titanium bimetallic complex [{Ti(C5H5)2Cl}2{mu-1,4-O (C6H2Me2)O-}] (5) is better prepared by method d by treatment of the dilithium salt Li2[1,4-O (2,3-C6H2Me2)O-] with [Ti(C5 H5)2Cl2] whereas the trimetallic compound [{Ti(C5H5)2Cl}3 (mu3-1,3,5-C6H3O3-)] (9) can be prepared directly from 1,3,5-trihidroxybenzene in the presence of NEt3 (method b). Finally, bis(cyclopentadienyl)zirconium complexes [{Zr(C5H5)2Cl}2 {mu-1,4-O(C6H2Me2)O-}] (6) and [{Zr(C5H5)2Cl}3 (mu3-1,3,5-C6H3O3-)] (10) are obtained from [Zr(C5H5)2ClH] (method c). The structure of complex 3 has been determined by X-ray diffraction methods.

In situ controlled radical polymerization (CRP) is considered as an important approach to graft polymer brushes with controlled grafting density, functionality, and thickness on graphene layers. Polymers are tethered with chain end or through its backbone to the surface or edge of graphene layers with two in situ polymerization methods of ?grafting from? and ?grafting through? and also a method based on coupling reactions known as ?grafting to?. The ?grafting from? method relies on the propagation of polymer chains from the surface- or edge-attached initiators. The ?grafting through? method is based on incorporation of double bond-modified graphene layers into polymer chains through the propagation reaction. The ?grafting to? technique involves attachment of pre-fabricated polymer chains to the graphene substrate. Here, physical and chemical attachment approaches are also considered in polymer-modification of graphene layers. Combination of CRP mechanisms of reversible activation, degenerative (exchange) chain transfer, atom transfer, and reversible chain transfer with various kinds of grafting reactions makes it possible to selectively functionalize graphene layers. The main aim of this review is assessment of the recent advances in the field of preparation of polymer-grafted graphene substrates with well-defined polymers of controlled molecular weight, thickness, and polydispersity index. Study of the opportunities and challenges for the future works in controlling of grafting density, site-selectivity in grafting, and various topologies of the brushes with potential applications in stimuli-responsive surfaces, polymer composites, Pickering emulsions, coating technologies, and sensors is also considered.
