As our research focuses on anticancer drugs, a series of novel derivatives of flexicaulin A (FA), an ent-kaurene diterpene, condensed with an aromatic ring were synthesized, and their antiproliferative activities against four human cancer cell lines (TE-1, EC109, MCF-7, and MGC-803) were evaluated. The activities of most of the new compounds were better than those of FA. Compound 2y exhibited the best activity with an IC50 value reaching 0.13 mu M against oesophageal cancer cells (EC109 cells). The IC50 values for 2y in normal cells (GES-1 cells and HUVECs) were 0.52 mu M and 0.49 mu M, respectively. Subsequent mechanistic investigations found that compound 2y can inhibit the proliferation of cancer cells and cell cloning. In addition, 2y could reduce the mitochondrial membrane potential, increase the apoptosis rate, and increase the ROS level in EC109 cells. Moreover, 2y can upregulate the expression of ROS/JNK pathway-related proteins (p-ASK1, p-MKK4, p-JNK, and p-Cjun (ser63)) and pro-apoptotic proteins (Bax, Bad, and Bim). In vivo experiments showed that 2y can inhibit tumour growth in nude mice. The mechanism involves an increase in protein expression in the ROS pathway, leading to changes in apoptosis-related proteins. In addition, compound 2y shows low toxicity. These results indicate that compound 2y holds promising potential as an antiproliferative agent. (c) 2020 Elsevier Masson SAS. All rights reserved.

A series of benzothiazole derivatives bearing a 1,3,4-thiadiazole moiety were designed, synthesized and evaluated for their antibacterial, antifungal and antiviral activities. The bioassay results indicated that most of target compounds showed good antiviral activities against tobacco mosaic virus (TMV) and antibacterial activities against Xanthomonas oryzae pv. oryzae (Xoo) and Ralstonia solanacearum (Rs). Especially, the anti-Xoo effect of title compounds 5k (N-(5-methoxybenzo[d]thiazol-2-yl)-2-((5-(2-tolyl)-1,3,4-thiadiazol-2-yl)thio)acetamide) and the anti-Rs effect of title compounds 5a (N-(5-nitrobenzo[d]thiazol-2-yl)-2-((5-(4-(trifluorom ethyl)phenyl)-1,3,4-thiadiazol-2-yl)thio)acetmide) respectively reached 52.4% and 71.6% at 100 mu g/mL, which are superior to that of bismerthiazol (32.0% and 52.3%). In addition, the protective and inactivation activities of title compound 5i (N-(5-methoxybenzo [d]thiazol-2-yl)-2-((5-(4-nitrophenyl)-1,3,4-thiadiazol-2-yl)thio)acetamide) against TMV were 79.5% and 88.3%, respectively, which are better than that of ningnanmycin (76.4% and 86.8%). The above research showed that benzothiazole derivatives bearing a 1,3,4-thiadiazole moiety may be used as potential molecular templates in searching for highly-efficient antiviral and antibacterial agents.

4-Methyltetrahydropyran (4-MeTHP) is a hydrophobic cyclic ether with potential for industrial applications. We herein report, for the first time, a comprehensive study on the performance of 4-MeTHP as an organic reaction solvent. Its broad application to organic reactions includes radical, Grignard, Wittig, organometallic, halogen-metal exchange, reduction, oxidation, epoxidation, amidation, esterification, metathesis, and other miscellaneous organic reactions. This breadth suggests 4-MeTHP can serve as a substitute for conventional ethers and harmful halogenated solvents. However, 4-MeTHP was found incompatible with strong Lewis acids, and the C-O bond was readily cleaved by treatment with BBr3. Moreover, the radical-based degradation pathways of 4-MeTHP, THP and 2-MeTHF were elucidated on the basis of GC-MS analyses. The data reported herein is anticipated to be useful for a broad range of synthetic chemists, especially industrial process chemists, when selecting the reaction solvent with green chemistry perspectives.

The 1,3-benzodioxol moiety present in safrole, apiole, and myristicin essential oils and benzodioxol derivatives have shown a wide range of biological activities including antiepileptic, analgesic, antituberculosis, and antimicrobial potentials. Here, we have tested the antibacterial and antioxidant activities of a series of benzodioxol derivatives. Twelve compounds of aryl acetate and acetic acid benzodioxol were evaluated against different types of bacterial strains, including Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, and Pseudomonas aeruginosa using the broth dilution method, and the most potent compound was 3e, which exhibited the bacterial growth of with MICs of 125 (S. aureus), 250 (E. coli), 220 (E. faecalis), and 100 mu g/mL (P. aeruginosa). Our positive control, cinoxacin, had MICs of 250 (S. aureus), 250 (E. coli), 250 (E. faecalis), and 500 mu g/mL (P. aeruginosa). Antioxidant activity was evaluated for the synthesized compounds utilizing the DPPH assay. The 3a compound was the most active with an IC50 value of 21.44 mu g/mL, while the IC50 values of compounds 3b, 3e, and 3f were 96.07, 58.45, and 72.17 mu g/mL, respectively. In contrast, all compounds with the acetic acid functional group had weaker activity, with an IC50 range of 193.52-289.78 mu g/mL compared with the potent antioxidant agent Trolox (IC50 = 1.93 mu g/mL). In the present paper, new benzodioxol-based aryl acetate and acetic acid derivatives were evaluated for their antibacterial and antioxidant activities. The outcomes revealed that the antibacterial and antioxidant properties of some of the synthesized benzodioxol aryl acetate and acetic acid derivatives can be considered as valuable materials for the pharmaceutical industry. Thus, these molecules should be further evaluated in vivo as lead compounds for the discovery of new drug candidates.

The applicant Syngenta Crop Protection AG submitted a request to the competent national authority in Finland to evaluate the confirmatory data that were identified for propiconazole in the framework of the MRL review under Article 12 of Regulation (EC) No 396/2005 as not available. Following the decision on the non-renewal of the approval of propiconazole and the decision to lower the maximum residue levels (MRLs) for propiconazole to the limit of quantification (LOQ) for all commodities, the data gaps identified in the MRL review are no longer relevant. EFSA summarised some new studies on the toxicological profile of propiconazole metabolites CGA91305, SYN547889 and NOA436613, which were assessed by the rapporteur Member State. Overall, the available information is not sufficient to characterise the toxicological profile of metabolites convertible to 2,4-dichlorobenzoic acid as data gaps still exist for SYN547889, NOA436613, CGA118244, CGA118245, CGA91304 and CGA91305.

Structural modifications of nicotinamide, a form of vitamin B3, gave rise to a series of compounds (8aa-8ce) that exhibit activities as type I positive allosteric modulators (PAMs) of human alpha 7 nAChR expressed in Xenopus oocytes in two-electrode voltage clamp assay. The compound 8ai was a potent and efficacious PAM with an EC50 = 3.34 +/- 1.13 mu M and the maximum activation effect of alpha 7 current over 1474 +/- 246% in the presence of acetylcholine (100 mu M). It is highly specific to alpha 7 nAChR over other subtypes of nAChR and 5-HT3A receptors. The structure-activity relationship analysis identified a key skeleton of nicotinamide nucleus critical for biological activity. Taken together, the 8ai as a type I PAM of alpha 7 nAChR may be beneficial for improvement of cognitive deficit.

2-Pyridyl ketones widely appear in bioactive molecules, natural products, and are employed as precursors of chiral 2-pyridine alky/aryl alcohols or 2-aminoalkyl pyridine ligands for asymmetric catalysis. Herein, a practical method for the rapid synthesis of 2-pyridyl ketone library in continuous flow is reported, in which the 2-lithiopyridine formed by Br/Li exchange reacts with commercially available esters to obtain 2-pyridyl ketones in a good yield at short reaction time. This protocol functions broadly on a variety of esters and has been applied to the synthesis of TGF-beta type 1 receptor inhibitor LY580276 intermediate in an environmentally friendly method. It is rapid, reliable, and cost-efficient to afford diverse kinds of 2-pyridyl ketones in the compound library.

Application In Synthesis of 1-Chloro-2-methylbenzene. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Global retention models and their application to the prediction of chromatographic fingerprints published in 2021, Reprint Addresses Torres-Lapasio, JR (corresponding author), Univ Valencia, Dept Analyt Chem, Fac Chem, C Dr Moliner 50, Burjassot 46100, Spain.. The CAS is 95-49-8. Through research, I have a further understanding and discovery of 1-Chloro-2-methylbenzene.

The resolution of samples containing unknown compounds of different nature, or without standards available, as is the case of chromatographic fingerprints, is still a challenge. Possibly, the most problematic aspect that prevents systematic method development is finding models that describe without bias the retention behaviour of the compounds in the samples. In this work, the use of global models (able to describe the whole sample) is proposed as an alternative to the use of individual models for each solute. Global models contain parameters that are specific for each solute, while other parameters -related to the column and solvent- are common for all solutes. A special regression procedure is presented for the construction of global models, which are applied to predict highly complex chromatograms, such as chromatographic fingerprints, for diverse experimental conditions in isocratic and gradient elution. Another interesting application is the prediction of molecular properties, such as log P-o/w from the specific solute parameters of the global models. The examined adapted models are based on the equations proposed by Snyder, Schoenmakers, Neue and Kuss, Jandera, and Bosch Roses to describe the retention. In all cases, the predictive capability was very satisfactory. Two cases of study were considered: chromatograms of camomile extracts analysed using acetonitrile gradients, and a set of 145 known compounds in a wide range of structures and functionalities, eluted isocratically with acetonitrile/water mobile phases.
