A one-pot and modular approach to the synthesis of 2,4(5)-disubstituted imidazoles was developed based on ketone oxidation, employing catalytic HBr and DMSO, followed by imidazole condensation with aldehydes. This methodology afforded twenty-nine disubstituted NH-imidazoles (23%-85% yield). A three-step synthesis of 20 kinase inhibitors was achieved by employing this oxidation- condensation protocol, followed by bromination and Suzuki coupling in the imidazole ring to yield trisubstituted NH-imidazoles (23%-69%, three steps). This approach was also employed in the synthesis of known inhibitor GSK3037619A.

A full understanding of changes of the microbiome and metabolome during Napier grass silage in relation to aerobic exposure can improve the nutritional value and extend the aerobic stability of this important feed in tropical and subtropical regions. The round bale silage of Napier grass was prepared with deionized water (control) and screened strains Lactobacillus rhamnosus LR753 (LR753) and L. buchneri 40788 (LB). Silages were stored at ambient temperature (30-40 degrees C) for 60 days, followed by 2 and 4 days of aerobic exposure. Strains LB and LR753 significantly improved aerobic stability (>84 h vs. 18 h of control) of baled Napier grass silage by inhibiting the growth of Saccharomycetales as for the higher production of acetic acid (P < 0.05). Weissella and Issatchenkia spp. were the dominant bacteria and fungi in 60-day silage, respectively. LC-MS/MS detected a total of 426 metabolites throughout ensiling and aerobic exposure. With the decrease of Weissella spp. and the increase of Acetobacter spp., the metabolites associated with both were mainly odor-related (3-methylbutanoic acid, isoquinoline, and cuminaldehyde) and amines (tryptamine and tyramine) in control silage, while more antimicrobial activity metabolites were found in strains LB and LR753-treated silage (methylbutanoic acid, 1,2-propanediol, and tiglic acid). Screened local strain LR753 showed a promising potential for improving silage fermentation and aerobic stability of Napier grass. The present study indicates that adequately describing the microbiome and metabolome of silages during fermentation and aerobic exposure can improve ensiling practices and the screening of silage inoculants that act synergistically with the natural microbiome of the forage in hot and humid areas.

Owing to the increasing amount of waste materials around the globe, the conversion of waste or secondary by-products to value-added products for various applications has gained significant interest. Herein, two novel agro-food waste products, Musa sp. ‘Malbhog’ peel ash (MMPA) and Musa Champa Hort. ex Hook. F. peel ash (MCPA) are used as catalysts to promote an inexpensive, efficient and eco-friendly carbon-carbon bond forming crossed aldol reaction at room temperature in solvent free conditions. Furthermore, the resulting products were subjected to reactions with these promoters in an oxygen atmosphere and led to the formation of novel flavone derivatives. Moreover, the used catalysts were properly characterized using different sophisticated analytical techniques such as Fourier-transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), Brunauer-Emmett-Teller analysis (BET), Raman spectroscopy, scanning electron microscopy energy dispersive X-ray spectroscopy (SEM-EDS), transition electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA) along with element detection using atomic absorption spectroscopy and ion chromatographic methods. These two approaches are metal free, as well as being devoid of any extra additives, co-catalysts, harsh conditions, the use of column chromatography for purification and result in a higher yield of the product within a short space of time. The catalytic abilities of the promoter were also examined to synthesize important bioactive molecules such as butein and apigenin at room temperature. With gram scale synthesis of the chalcone derivatives, the used catalysts (MMPA and MCPA) were further reused for five cycles and did not demonstrate any loss in catalytic activity.

Volatile content during postharvest is a critical factor affecting the quality of rose products. However, changes in the volatile content of cut rose flowers during vase life have not yet been identified although the maturity of flower petals may result in the significant changes of volatile profiles. The present study investigated volatile changes in the petals of two rose varieties, ‘Fuego’ exhibited to longer vase life and ‘Red eagle, during vase life. ‘Fuego’ petals contained 31 volatiles, of which 12 increased and 11 decreased in content during vase life. ‘Red Eagle’ petals contained 37 volatiles, of which 9 increased and 19 decreased. The major components that increased during vase life included 2-ethylhexan-1-ol and phenylmethanol in ‘Fuego’ and hexan-1-ol and 2-phenylacetaldehyde in both cultivars, whereas the major components that decreased during vase life included methyl butanoate in ‘Fuego’, 3,5-dimethoxytoluene in ‘Red Eagle’, and 2-methylhexane in both cultivars. The total volatile content was maintained in ‘Fuego’ petals during the 6-day vase life, despite the changes in the content of individual volatile compound. By contrast, the total volatile content of ‘Red Eagle’ petals significantly decreased during vase life. Additionally, the volatile compounds that increased in content were relatively small molecules (<= C-8), whereas those that decreased in content during vase life were relatively large molecules (>= C-9). These results suggest that the analysis of volatile changes during vase life contribute to the harvest time selection of rose flowers and the determination of petal stages used for essential oil in many rose varieties.

The borane-catalyzed synthesis of dihydroquinoline-4-ones is developed. The amino-substituted chalcones undergo a 1,7-hydride shift upon Lewis acid activation to form a zwitterionic iminium enolate, which collapses to the dihydroquinoline-4-one scaffold. The reaction proceeds in high yields (75-99%) with an excellent diastereoselectivity of up to >99:1 (cis:trans). The reaction mechanism is investigated by kinetic, isotope labeling, and computational experiments.

A cheap, facile and metal-free photochemical protocol for the activation of aromatic aldehydes has been developed. Utilizing thioxanthen-9-one as the photocatalyst and cheap household lamps as the light source, a variety of aromatic aldehydes have been activated and subsequently converted in a one-pot reaction into amides, hydroxamic acids and esters in good to high yields. The applicability of this method was highlighted in the synthesis of Moclobemide, a drug against depression and social anxiety. Extended and detailed mechanistic studies have been conducted, in order to determine a plausible mechanism for the reaction.

An article Electrometric bromine number as a suitable method for the quantitative determination of phenols and olefins in hydrotreated pyrolysis bio-oils WOS:000652032600064 published article about QUANTIFICATION; TITRATION in [Auersvald, Milos; Stas, Martin; Simacek, Pavel] Univ Chem & Technol, Dept Petr Technol & Alternat Fuels, Tech 5, Prague 16628 6, Czech Republic in 2021, Cited 29.

Bio-oils after hydrotreatment can still contain significant amount of phenols and cyclic olefins as the products of an incomplete deoxygenation. The removal of these compounds would be necessary to produce suitable components for automotive fuels. However, no routine method currently exists for the reliable determination of these groups in hydrotreated bio-oils (HBOs). In this paper, we analyzed 140 different pure oxygenates as model compounds using the bromine number method (ASTM D1159) observing that most compounds present in HBOs react with one equivalent of bromine. The determination of phenols using bromine number method in crude biooil is complicated especially by the presence of guaiacols and syringols that react with more than one equivalent of bromine and, thus, the obtained result is significantly overestimated. Further we optimized the chromatographic separation of hydrocarbons from HBOs for the selective determination of olefins content. As no other reactive compounds under the conditions of the method, besides phenols and olefins, were observed in HBOs, the difference between HBO bromine number (before hydrocarbons separation) and olefins content correspond to the total amount of phenols. The method was finally applied to 11 HBOs with different content of oxygen, providing a good correlation between phenols and oxygen content.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.

A regioselective radical C-H trifluoromethylation of aromatic compounds was developed using cyclodextrins (CDs) as additives. The C-H trifluoromethylation proceeded with high regioselectivity to afford the product in good yield, even on the gram scale. In the presence of CDs, some substrates underwent a single trifluoromethylation selectively, whereas mixtures of single- and double-trifluoromethylated products were formed in the absence of the CD. H-1 NMR experiments indicated that the regioselectivity was controlled by the inclusion of a substrate inside the CD cavity.

The novel metal-organic framework Co-2(bdda)(1.5)(OAc)(1)5H(2)O (UoB-3) was synthesized via a simple method at room temperature. UoB-3 was characterized by the different methods, including X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), N-2-adsorption/desorption and elemental analysis. The catalytic ability of UoB-3 was detected to be excellent for primary and secondary alcohols oxidation reaction with high yields under solvent-free conditions. Moreover, UoB-3 was highly active for Henry reaction of different aldehydes with nitromethane in water as a green solvent. The nanocatalyst can be recycled for five consecutive cycles without losing its activity and structural rigidity. The antibacterial activity of UoB-3 nanostructures towards Gram-negative bacteria, Escherichia coli and Gram-positive bacteria, Bacillus cereus was also evaluated by using an inhibition zone test. These nanostructures exhibited strong antibacterial effect against both of them. The purpose of this study was the developing metal-organic framework materials with the enhanced activity in various fields.
