Alzheimer’s disease (AD) is a neurodegenerative disorder with multifactorial pathogenesis. Monoamine oxidase (MAO) and acetylcholinesterase enzymes (AChE) are potential targets for the treatment of AD. A total of 15 new propargyl containing 4,6-diphenylpyrimidine derivatives were synthesized and screened for the MAO and AChE inhibition activities along with ROS production inhibition and metal-chelation potential. All the synthesized compounds were found to be selective and potent inhibitors of MAO-A and AChE enzymes at nanomolar concentrations. VB1 was found to be the most potent MAO-A and BuChE inhibitor with IC50 values of 18.34 +/- 0.38 nM and 0.666 +/- 0.03 mu M, respectively. It also showed potent AChE inhibition with an IC50 value of 30.46 +/- 0.23 nM. Compound VB8 was found to be the most potent AChE inhibitor with an IC50 value of 9.54 +/- 0.07 nM and displayed an IC50 value of 1010 +/- 70.42 nM against the MAO-A isoform. In the cytotoxic studies, these compounds were found to be nontoxic to the human neuroblastoma SH-SYSY cells even at 25 mu M concentration. All the compounds were found to be reversible inhibitors of MAO-A and AChE enzymes. In addition, these compounds also showed good neuroprotective properties against 6-OHDA- and H2O2-induced neurotoxicity in SH-SYSY cells. All the compounds accommodate nicely to the hydrophobic cavity of MAO-A and AChE enzymes. In the molecular dynamics simulation studies, both VB1 and VB8 were found to be stable in the respective cavities for 30 ns. Thus, 4,6-diphenylpyrimidine derivatives can act as promising leads in the development of dual-acting inhibitors targeting MAO-A and AChE enzymes for the treatment of Alzheimer’s disease.

Sugarcane (SC) is a perennial grass widely cultivated in tropical and subtropical regions. However, its cultivation in Europe is residual, where Madeira Island, Portugal, is the only region where SC continues to be extensively cultivated. For the first time, the volatile profiles of regional cultivars were established by solid-phase microextraction combined with gas chromatography-mass spectrometry. Different volatile profiles for each cultivar were recognized, identifying 260 volatile organic compounds belonging to 15 chemical classes, such as aldehydes, alcohols, ketones, hydrocarbons, esters, and terpenes. Chemometric analysis procedure, namely, one-way ANOVA with Tukey’s test, principal component analysis, partial least-square analysis, linear discriminant analysis, and hierarchical clustering analysis, allowed the differentiation between all regional cultivars. This study represents an important contribution for the maintenance of biodiversity and subsistence of the SC industry in Europe. Furthermore, it is also a valuable contribution to establish the typicality of traditional SC-based products, such as SC honey.

Pterocarpus is one of the most widely used timber resources on the market. But the utilization rate has been low. In order to improve the utilization of Pterocarpus processing residue, as well as explore the reason of its good decay-resistance. In this study, the antifungal mechanism of Peterocarpes spp., aqueous extracts and ethanol extracts of three Pterocarpus species were studied. The antimicrobial active factors were analyzed by gas chromatography-mass spectrometry. Italian poplar (Populus euramevicana cv. ‘I-214’) wood was immersed in the extracts and then inoculated with both Coriolus versicolor and Glaeophyllum trabeum. The antimicrobial properties of the extracts were studied, and the mechanism underlying these properties were analyzed using gas chromatography-mass spectrometry. The results showed that the yield of ethanol extracts from the three Pterocarpus species was significantly higher than that of aqueous extracts. Pterocarpus soyauxii and Pterocarpus macarocarpus produced the highest yield of ethanol extracts (28.59%) and aqueous extracts (14.31%), respectively. With increasing concentrations, the antimicrobial activities of aqueous extracts of Pterocarpus angolensis and Pterocarpus macarocarpus gradually increased, while the antimicrobial activity of other extracts remained constant. Gas chromatography-mass spectrometry analysis identified a considerable number of phenols, ketones, amines, and aromatic compounds in all extracts, which is consistent with their antimicrobial activity and suggests synergism among the chemicals.

Residues of bisphenol A (BPA) are ubiquitously detected in the surface water due to its widespread usage. This study systematically investigated the dissipation and kinetics of BPA under simulated hydrolysis, direct and indirect photolysis, bacterial degradation, microbial degradation and natural attenuation in microcosm. Structural equation modeling (SEM) by using partial least square method in path coefficient analysis suggested that the microbial degradation was the major factor involved in the natural attenuation of BPA. The potential transformation products were identified by using liquid chromatography high-resolution mass spectrometry (LC-HRMS) and stable isotope tracing technique by simultaneous performing gas chromatography combustion isotope ratio mass spectrometry (GC-C-IRMS) and gas chromatography mass spectrometry (GC-MS). A total of fourteen including three novel transformation products of BPA were identified to indicate five possible pathways. An increased yield of labeled (delta C-13) CO2 and detection of C-13-labeled phospholipid fatty acids (PLFAs) indicated the mineralization of BPA and possible utilization of BPA or its transformation products by microbes for cellular membrane synthesis, respectively.

In an effort to develop novel Bax activators for breast cancer treatment, a series of diverse analogues have been designed and synthesized based on lead compound SMBA1 through several strategies, including introducing various alkylamino side chains to have a deeper access to S184 pocket, replacing carbon atoms with nitrogen, and reducing the nitro group of 9H-fluorene scaffold. Compounds 14 (CYD-2-11) and 49 (CYD-4-61) have been identified to exhibit significantly improved antiproliferative activity compared to SMBA1, with IC50 values of 3.22 mu M and 0.07 mu M against triple-negative breast cancer MDA-MB-231 and 3.81 mu M and 0.06 mu M against ER-positive breast cancer MCF-7 cell lines, respectively. Mechanism of action studies of compound 49 indicated that it can activate Bax protein to induce cytochrome c release and regulate apoptotic biomarkers, leading to cancer cell apoptosis. Further in vivo efficacy studies of compounds 14 and 49 in nude mice bearing MDA-MB-231 tumor xenografts demonstrated that these drug candidates can significantly suppress tumor growth, indicating their therapeutic potential for the treatment of breast cancer.

Computed Properties of C5H8O2. I found the field of Chemistry very interesting. Saw the article Ring Expansion Leads to a More Potent Analogue of Ipomoeassin F published in 2020, Reprint Addresses Shi, WQ (corresponding author), Ball State Univ, Dept Chem, Muncie, IN 47306 USA.. The CAS is 80-59-1. Through research, I have a further understanding and discovery of (E)-2-Methylbut-2-enoic acid.

Two new ring-size-varying analogues (2 and 3) of ipomoeassin F were synthesized and evaluated. Improved cytotoxicity (IC50: from 1.8 nM) and in vitro protein translocation inhibition (IC50: 35 nM) derived from ring expansion imply that the binding pocket of Sec61 alpha (isoform 1) can accommodate further structural modifications, likely in the fatty acid portion. Streamlined preparation of the key diol intermediate 5 enabled gram-scale production, allowing us to establish that ipomoeassin F is biologically active in vivo (MTD: similar to 3 mg/kg).

The synthesis of nitrogen- and oxygen-containing heterocycles has found many applications in the preparation of biomedical intermediates, yet actual synthetic procedures display limitations such as high-loading catalysts, harsh reaction conditions and tedious preparation of heterogeneous catalysts. Alternatively, photocatalysis allows to access functional products with minimum synthetic procedures and waste generation. Here, we present an efficient, simple, green protocol for the synthesis of N- and O-containing six-membered-ring compounds under mild conditions under visible blue light. Various aldehydes and 1,3-diketones can be reacted to afford eight series of corresponding 1,4-dihydropyridines and 4H-benzo[b]pyrans. This protocol has some merits such as the use of abundant and sustainable aqueous ethanol as solvent, short reaction time (within 60 min), no need of catalyst and broad functional group tolerance to afford 81 different series of target molecules in 75-96% yield under mild conditions.

The non-linear optical technology is gaining huge attention to the thermal and mechanical stability, electrical property, and modulate signal flexibility that could be used in uprising optoelectronics devices based on powerful laser technologies such as all optical switches, lightemitting diodes, data storage and optical communication systems. In this paper, selected three phenanthrolines derivatives [2-phenyl-1H-phenanthro[9,10-d]imidazole (1), 2-(4-nitrophenyl)1H-phenanthro[9,10-d]imidazole(2),2-(4-methoxyphenyl)-1H phenanthro[9,10-d]imidazole (3)] were synthesized and characterized using UV, FT-IR and H-1 NMR. Cubic nonlinear optical properties susceptibility (chi(<3>)(THG)) were analyzed and evaluated using the third harmonic generation technique on thin films at 1064 nm. The investigation study is completed by a theoretical calculation in which the different quantum chemical parameters like frontier molecular orbital analysis, energy gap, dipole moment, average polarizability, and first second hyperpolarizability were analyzed using Density Functional Theory (DFT). The non-linear optical behavior of the selected three phenanthrolines derivatives is confirmed through the obtained high THG efficiency. Moreover, a significant correlation between the molecular structures and the optoelectronic properties is demonstrated.
