A series of 1,2,3-triazole-containing Sorafenib analogues, in which the aryl urea moiety of Sorafenib (1) was replaced with a 1,2,3-triazole ring linking a substituted phenoxy fragment, were prepared successfully via Huisgen 1,3-dipolar cycloaddition and nucleophilic aromatic substitution. The studies of cytotoxicity towards human hepatocellular carcinoma (HCC) cell lines, HepG2 and Huh7, indicated that p-tert-butylphenoxy analogue 2m showed significant inhibitory activity against Huh7 with IC50 = 5.67 +/- 0.57 mu M. More importantly, 2m showed low cytotoxicity against human embryonal lung fibroblast cell line, MRC-5, with IC50 > 100 mu M, suggesting its highly selective cytotoxic activity (SI > 17.6) towards Huh7 which is much superior to that of Sorafenib (SI = 6.73). The molecular docking studies revealed that the analogue 2m bound B-RAF near the binding position of Sorafenib, while it interacted VEGFR2 efficiently at the same binding position of Sorafenib. However, 2m exhibited moderate inhibitory activity toward B-RAF, implying that its anti-Huh7 effect might not strictly relate to inhibition of B-RAF. Wound healing and BrdU cell proliferation assays confirmed anti-cell migration and anti-cell proliferative activities towards Huh7. With its inhibitory efficiency and high safety profile, 2m has been identified as a promising candidate for the treatment of HCC.

Metal-free N-heterocyclic carbene (NHC) organocatalysis in D2O medium was elegantly utilised for the synthesis of highly diastereoselective deuterated spiropyran derivatives. Selective deuteration was exclusively achieved on the C5 carbon atom of the pyran ring. Quantum chemical calculations were performed to prove the preferential formation of a single diastereomer from the possible four diastereomers. The scope of NHC organocatalysis in D2O was also extended for the synthesis of deuterated spirooxindole derivative.

A composite film with multiple anti-counterfeiting features was demonstrated by superposing quantum dots (QDs) polymer matrix (film A) and cholesteric liquid crystal film (film B) together. The first-line and second-line anti-counterfeiting characteristics were successfully implemented by employing thermochromic, angular photochromic, and circularly polarized discoloration of film B, respectively. By initiatively utilizing the different relative positions between the fluorescence emission peak (lambda(em)) of film A and the central selective reflection wavelength (lambda(em)) of film B at different temperatures, which resulted in changes in the fluorescence spectra or the different presence of latent patterns, the most important third-line anti-counterfeiting feature was successfully achieved.

Novel arginine-functionalized starch-based nanoparticles (Arg-SNPs) were synthesized and characterized by Fourier transforms infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), X-ray diffraction (XRD) and thermos-gravimetric analyses (TGA) techniques. Arg-SNP was used as a highly efficient and macromolecule-supported recyclable nanocatalyst for the one-pot reaction between thiourea and iodine with various substituted methylcarbonyls to afford the corresponding diheteroaryl thioethers in high-to-quantitative yields. The nanocatalyst was recycled at least five times without significant decrease in the catalytic activity. (C) 2019 Elsevier B.V. All rights reserved.

Divergent total syntheses of 10 yaequinolone-related natural products have been achieved for the first time by latestage C-H olefination of 3,4-dioxygenated 4-aryl-5-hydroxyquinolin-2(1H)-ones, core structures of this family of natural products. A robust synthetic methodology to construct the core structures has been established, and the C-H olefination reaction has been carried out with synthetically useful yields and high levels of site-selectivity under mild reaction conditions in the presence of a Pd/S,O-ligand catalyst.

SDS of cas: 120-14-9. I found the field of Chemistry very interesting.

A series of twenty new chloropyrazine conjugated benzothiazepines (22-41) have been synthesized with 58%-95% yields. The compounds were characterized by using different spectroscopic techniques including FT-IR, H-1 NMR, C-13 NMR spectroscopy and mass spectrometry. The synthesized compounds (22-41) and their precursor chalcones (2-21) were evaluated for antitubercular and cytotoxic activities. Additionally, compounds 22-41 were also tested for antimicrobial activity. Among the chalcone series (2-21), compounds 7 and 14 showed significant antitubercular activities (MICs 25.51 and 23.89 mu M, respectively), whereas among benzothiazepines (22-41), compounds 27 and 34 displayed significant antimicrobial (MICs 38.02 mu M, 19.01 mu M) and antitubercular (MIC 18.10 mu M) activities. Compounds 7 and 41 displayed cytotoxic activities with IC50 of 46.03 +/- 1 and 35.10 +/- 2 mu M respectively. All the compounds were evaluated for cytotoxic activity on normal human liver cell lines (L02) and found to be relatively less selective towards this cell line. The most active compounds identified through this study could be considered as potential leads for the development of drugs with possible antimicrobial, antitubercular, and cytotoxic activities.

In this study, we attempted the chemical simplification of Psammaplin (PsA), while retaining its activity in vitro . Inspired by the previous Structure Activity Relationship (SAR) studies on various PsA analogues and relying on the fact that oxime is metabolically unstable, we initially designed and synthesized a diverse library of PsA analogues and evaluated for cytotoxic activity. Among 32 compounds of Psammaplin analogues synthesized, the compound 10b was almost equally active as parent Psammaplin in vitro. (C) 2020 Elsevier B.V. All rights reserved.

Malaria remains one of the most deadly infectious diseases, causing hundreds of thousands of deaths each year, primarily in young children and pregnant mothers. Here, we report the discovery and derivatization of a series of pyrazolo[3,4-b]pyridines targeting Plasmodium falciparum, the deadliest species of the malaria parasite. Hit compounds in this series display sub-micromolar in vitro activity against the intraerythrocytic stage of the parasite as well as little to no toxicity against the human fibroblast BJ and liver HepG2 cell lines. In addition, our hit compounds show good activity against the liver stage of the parasite but little activity against the gametocyte stage. Parasitological profiles, including rate of killing, docking, and molecular dynamics studies, suggest that our compounds may target the Q(o) binding site of cytochrome bc(1).

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.

A new and straightforward synthesis of the C-1-C-7 core fragment of nhatrangin A was achieved in 14 steps from achiral 3-hydroxybenzaldehyde, without the need of chiral reagents or enzymatic resolution to introduce the chiral centers. The key asymmetric steps include in particular a highly enantioselective organocatalyzed Michael addition on an aryl vinyl ketone, a Sharpless asymmetric epoxidation and a subsequent regioselective ring opening of the resulting chiral epoxide. This work represents the first formal enantioselective synthesis of nhatrangin A.
