Possible application of incorporating a well-known drug (benzocaine) with cyanoacetamide function to get a powerful synthon ethyl 4-cyanoacetamido benzoate. This synthetic intermediate was used as a precursor for the synthesis of triazine, pyridone, thiazolidinone, thiazole and thiophene scaffolds containing the benzocaine core. Facile coupling, Michael addition, condensation and nucleophilic attack reactions were used to synthesize our targets. The structural features of the synthesized scaffolds were characterized using IR,H-1 NMR,C-13 NMR and mass spectroscopy. The antibacterial activities against Gram-positive (Staphylococcus aureus,Bacillus subtilis) and Gram-negative bacteria (Escherichia coli,Pseudomonas aeruginosa) were evaluated using ampicillin as a reference drug. DNA/methyl-green colorimetric assay of the DNA-binding compounds was also performed. Theoretical studies of the newly synthesized compounds based on molecular docking and QSAR study were conducted. The molecular docking studies were screened by MOE software for the more potent antibacterial agent28band each native ligand against four ofS. aureusproteins 1jij, 2xct, 2w9s and 3t07. [GRAPHICS] .

Atkamine is a complex marine pyrroloiminoquinone alkaloid that comprises a heptacyclic scaffold bearing five different heterocycles and four contiguous stereocenters, and therefore it is a highly challenging target for synthetic chemists. We herein reported a modular synthetic strategy toward this alkaloid, featuring a formal [5 + 2] annulation and an asymmetric Michael addition. The efficient synthesis of the long-chain aliphatic aldehyde and chiral amino acetal fragments have been achieved. A simplified tetracyclic intermediate bearing the core structure of atkamine has been successfully constructed through the formal [5 + 2] annulation.

Based on our previously reported Bcl-2/Mcl-1 dual inhibitor 4-thiomorpholinyl-2-cyano-3-amidinophenalenone (A1) that simultaneously occupies the p2 and p4 hydrophobic pockets of Bcl-2 and Mcl-1, we optimized molecules with different bond angles of the groups extending to the p4 pocket and bulky hydrophobic groups to explore p2. Research on structure-activity relationship resulted in a new derivative B4 that is capable of occupying both the p2 and p4 more deeply and completely than A1, with K-i values determined by fluorescence polarization assay (FPAs) improving to 0.31 mu M for Bcl-2 and 0.16 mu M for Mcl-1. Furthermore, B4 exhibited selective lethality on cancer cells over normal cells. It showed stronger apoptosis induction than (-)-gossypol on a Bcl-2/Mcl-1-dependent cancer cell line and killed an Mcl-1-dependent cell line which is resistant to ABT-199 treatment.

Modular beta-borylacrylates have been validated as programmable, ambiphilic C-3-synthons in the cascade annulation of 2-halo-phenol derivatives to generate structurally and electronically diverse coumarins. Key to this [3+3] disconnection is the BPin unit which serves a dual purpose as both a traceless linker for C(sp(2))-C(sp(2)) coupling, and as a chromophore extension to enable inversion of the alkene geometry via selective energy transfer catalysis. Mild isomerisation is a pre-condition to access 3-substituted coumarins and provides a handle for divergence. The method is showcased in the synthesis of representative natural products that contain this venerable chemotype. Facile entry into pi-expanded estrone derivatives modified at the A-ring is disclosed to demonstrate the potential of the method in bioassay development or in drug repurposing.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

Natural microbiota plays an essential role in flavor compounds used in traditional food fermentation; however, the fluctuation in natural microbiota results in inconsistency in food quality. Thus, it is critical to reveal the core microbiota for flavor compound production and to construct a synthetic core microbiota for use in constant food fermentation. Here, we reveal the core microbiota based on their flavor production and cooccurrence performance, using Chinese light-aroma-type liquor as a model system. Five genera, Lactobacillus, Saccharomyces, Pichia, Geotrichum, and Candida, were identified to be the core microbiota. The synthetic core microbiota of these five genera presented a reproducible dynamic profile similar to that in the natural microbiota. A Monte Carlo test showed that the effects of five environmental factors (lactic acid, ethanol, and acetic acid contents, moisture, and pH) on the synthetic microbiota distribution were highly significant (P < 0.01), similar to those effects on a natural fermentation system. In addition, 77.27% of the flavor compounds produced by the synthetic core microbiota showed a similar dynamic profile (rho > 0) with that in the natural liquor fermentation process, and the flavor profile presented a similar composition. It indicated that the synthetic core microbiota is efficient for reproducible flavor metabolism. This work established a method for identifying core microbiota and constructing a synthetic microbiota for reproducible flavor compounds. This work is of great significance for the tractable and constant production of various fermented foods. IMPORTANCE The transformation from natural fermentation to synthetic fermentation is essential in constructing a constant food fermentation process, which is the premise for stably making high-quality food. According to flavor-producing and cooccurring functions in dominant microbes, we provided a system-level approach to identify the core microbiota in Chinese light-aroma-type liquor fermentation. In addition, we successfully constructed a synthetic core microbiota to simulate the microbial community succession and flavor compound production in the in vitro system. The constructed synthetic core microbiota could not only facilitate a mechanistic understanding of the structure and function of the microbiota but also be beneficial for constructing a tractable and reproducible food fermentation process.

BACKGROUND Intensifying weed resistance has challenged the use of existing acetohydroxyacid synthase (AHAS)-inhibiting herbicides. Hence, there is currently an urgent requirement for the discovery of a new AHAS inhibitor to effectively control AHAS herbicide-resistant weed species produced by target mutation. RESULTS To combat weed resistance caused by AHAS with P197L mutation, we built a structure library consisting of pyrimidinyl-salicylic acid derivatives. Using the pharmacophore-linked fragment virtual screening (PFVS) approach, hit compound 8 bearing 6-phenoxymethyl substituent was identified as a potential AHAS inhibitor with antiresistance effect. Subsequently, derivatives of compound 8 were synthesized and evaluated for their inhibitory activities. The study of the enzyme-based structure-activity relationship and structure-resistance relationship studies led to the discovery of a qualified candidate, 28. This compound not only significantly inhibited the activity of wild-type Arabidopsis thaliana (At) AHAS and P197L mutant, but also exhibited good antiresistance properties (RF = 0.79). Notably, compared with bispyribac at 37.5-150 g of active ingredient per hectare (g a.i. ha(-1)), compound 27 exhibited higher growth inhibition against both sensitive and resistant Descurainia sophia, CONCLUSION The title compounds have great potential to be developed as new leads to effectively control herbicide-resistant weeds comprising AHAS with P197L mutation. Also, our study provided a positive case for discovering novel, potent and antiresistance inhibitors using a fragment-based drug design approach. (c) 2020 Society of Chemical Industry
