Inosine 5 ‘-monophosphate dehydrogenase (IMPDH) is a vital enzyme involved in the de novo synthesis of guanine nucleotides. IMPDH catalyzes a crucial step of converting IMP into XMP that is further converted into GMP. Microbial infections rely on the rapid proliferation of bacteria, and this requires the rate-limiting enzyme IMPDH to expand the guanine nucleotide pool and hence, IMPDH has recently received lots of attention as a potential target for treating infections. Owing to the structural and kinetic differences in the host IMPDH and bacterial IMPDH, a selective targeting is possible and is a crucial feature in the development of new potent and selective inhibitors of bacterial IMPDH. Earlier screening of small molecules revealed a structural requirement for the bacterial/protozoal IMPDH. Early optimization of benzimidazole and benzoxazole scaffolds led to the discovery of new potent and selective inhibitors of pathogenic IMPDH. Further research is vastly focused on the development of highly potent and selective inhibitors of various bacterial IMPDHs. Such studies reveal the importance of this excellent target for treating infectious diseases. The current review focuses on the recent developments in the discovery and development of selective inhibitors of bacterial/protozoal IMPDH with emphasis on the inhibition mechanism and structure-activity relationship.

In this study, we explore the use of two kinds of inorganic sieves, microporous MFI zeolite and mesoporous MCM-41 silica, as fillers to enhance the gas transport characteristics of thermally rearranged (TR) poly(hydroxyimides) (HPI). To the best of our knowledge, this is the first report on the use of these fillers to modify properties of TR HPIs, except for our previous research on MCM-41 filled HPIs based on BPADA dianhydride. In this work, 6FDA-HAB and BPADA-HAB varying in gas permeability and properties were selected as matrices for preparation of mixed matrix membranes (MMM) with the aim of studying the effect of both the kind of filler and a matrix on thermal rearrangement and properties of the resultant TR-MMMs. In addition to pure gas permeability measurements, HPIs and MMMs were examined by WAXD, SEM, TGA, DMA, and tensile tests before and after thermal rearrangement. For all MMM precursors, the permeability increased in proportion to the filler loading (e.g. by 1.2-4.4 times for O-2) while selectivity remained virtually the same. The same effect of improved permeability and maintained selectivity was observed for the series of TR-MMMs; for example, TR-MMM based on 6FDA and filled with 7 wt% of MCM-41 exhibited 6.7 fold higher O-2 permeability over its filled precursor. The permeation properties of the filled membranes showed a strong dependence on both the kind of matrix and filler. The addition of MCM-41 particles to BPADA-HAB increased permeability more than the incorporation of the similar amount of MFI ones, while the contrary was true for 6FDA-HAB. The best result, comprising the position on the upper bound for He/N-2, has been achieved for 6FDA-HAB filled with 25 wt% of MFI, whereas its TR analogue showed the highest 20.4 fold permeability improvement.

In order to explore the relationship between the antioxidant activity and structure of fifteen benzofuran derivatives, we carried out a QSAR study using multiple linear regression (MLR) and artificial neural network (ANN) methods. Six descriptors were used as input data (molar weight, surface area, octanol-water partition coefficient, hydration energy, highest occupied molecular orbital energy and lowest unoccupied molecular orbital energy). The electronic properties were derived at the B3LYP/6-31 G (d,p) level. Benchmarks on furan and benzofuran subunits and their comparison to the experiment showed that this level of theory is good enough. The output data correspond to the antioxidant activity as given by IC50. The predicted properties are in agreement with experimental values. Our study shows that 80% of studied molecules are in accordance with the Lipinski and Veber rules and reach the optimal lipophilicity indices. In addition, statistical analysis reveals that ANN technique with (6-2-1) architecture is more significant than MLR model. (C) 2019 Elsevier B.V. All rights reserved.

In this study, new benzoxazole-linked pyrrolidinone heterocyclic compounds were synthesized by an eco-efficient strategy using substituted benzylamines and 2-aminophenol under ultrasonic irradiation in the presence of a newly designed metal-free deep eutectic solvent (DES). This DES was prepared by using a eutectic mixture of urea and a synthesized glycine-derived ionic liquid. X-ray diffraction and infrared spectroscopy were employed to investigate the structure of the ionic liquid and characterize the DES, respectively. This method exhibited key advantages of high productivity, a short reaction time, and simple processing. Moreover, this DES was easily separated from reaction mixtures and can be recycled for multiple reactions. (C) 2020 Elsevier B.V. All rights reserved.

Copper or silver-catalyzed direct C(sp(2))-H/N-H electrochemical cross-coupling of phthalimide and heterocyclic arenes (2-phenylpyridine, benzo[h]quinoline, benzoxazole, and benzothiazole, etc.) for the efficient synthesis of phthalimide derivatives is described. This reaction features good yield, mild conditions, and broad substrate scope, which provides an efficient and straightforward protocol to access this type of tertiary amines. For the first time, the proposed protocol is based not only on a copper catalyst but also on silver, which has never been used for this purpose before, and both give comparable results. Mechanistic investigations (voltammetry, ESR studies) disclosed that a free-radical pathway might be excluded in this process accomplished through Cu(I)/Cu(II)/Cu(III) or Ag(I)/Ag(III) cycles.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 76-37-9, you can contact me at any time and look forward to more communication. Computed Properties of https://www.ambeed.com/products/76-37-9.html.

Owing to its high reactivity and commercial availability, 2-cyanoacetohydrazide can be utilized as a versatile and appropriate intermediate for synthesis of a broad variety of heterocyclic compounds. Thus, 2-cyanoacetohydrazide and 2-(1,3-dioxoisoindolin-2-yl) acetyl chloride were used as starting materials for construction of new heterocyclic compounds bearing 1,3-dioxoisoindoline moiety. The newly synthesized compounds were recognized by elemental analyses and spectral data (IR,H-1-NMR, and(13)C-NMR spectra). The synthesized compounds were screened for their anti-proliferative activity against two human epithelial cell lines; breast (MCF-7) and liver (HepG2) as well as to normal fibroblasts (WI-38). The data showed distinctly that compounds1and12presented promisingin-vitroanti-proliferative activity against two cell lines (MCF-7 and HepG2) without harming normal fibroblasts.

The palladium complex of dendronized amine polymer (EG-Gn-Pd, n = 0, 1 and 2) having ethylene glycol-initiated polyepichlorohydrin as core was synthesized on a Merrifield resin support and was well characterized. Generally, palladium catalysts are known for carbon-carbon coupling reactions. Here, a developed catalyst was found to be good for benzoxazole synthesis. Higher generation dendronized polymer (EG-G2-Pd) was found to be better catalyst over lower generation dendronized polymers. Moreover, dendronized polymers were found to be a better catalyst over dendrigraft polymers. The catalyst reusability was checked and good yield was obtained for five cycles.

Though membrane distillation (MD) has been considered as a promising desalination process, it is still required to develop a desirable membrane which has high water flux and long-term stability for practical use in the MD process. In our previous work, thermally rearranged nanofiber membranes (TR-NFMs), which exhibited high water flux (80 kg m(-2) h(-1)) and salt rejection (> 99.99%) as well as outstanding long-term stability (more than 180 h), were first introduced as a promising candidate for MD applications. However, nascent TR-NFM is susceptible to fluctuations in operating conditions due to insufficient liquid entry pressure with water (LEPw). In continuation of our enhanced hydrophobic TR-NFM study, we develop fluorine-containing thermally-rearranged nanofiber membranes (F-TR-NFMs) for MD applications for the first time. F-TR-NFMs showed enhanced hydrophobic properties such as high water contact angle (143 degrees), high LEPw (1.3 bar), and high effective evaporation area (EEA) due to the introduction of fluorine atoms in the backbone of the TR membrane. As the result, the developed F-TR-NFMs exhibited outstanding MD performance (114.8 kg m(-2) h(-1) of water flux and > 99.99% of salt rejection at feed and permeate temperatures of 80 degrees C and 20 degrees C, respectively) and excellent energy efficiency (52.1% at feed and permeate temperatures of 50 degrees C and 20 degrees C, respectively). The long-term stability of F-TR-NFM is also investigated over more than 250 h of operation time.

A novel series of 1,3-benzoxazole and 1,3-dioxolane substituted benzimidazole-based N-heterocyclic carbene (NHC) precursors (6a-b and 11a-b) and their corresponding NHC-silver(I) acetate (12a-b and 14a-b) and bis-NHC-silver(I) hexafluorophosphate complexes (13a-b and 15a-b) were synthesized and characterized by H-1 NMR, C-13 NMR, ATR-IR spectroscopic methods and elemental analysis techniques. Also, the molecular structure of benzimidazolium salt (6a) and bis-NHC-silver(I) hexafluorophosphate complex (13b) were unambiguously established by single crystal X-ray diffraction analysis. Fascinatingly, bis-NHC-silver(I) hexafluorophosphate complex (13b) was revealed to be dinuclear in nature. All the azolium salts (6a-b and 11a-b) as well as the corresponding silver(I) complexes (12a-b, 13a-b, 14a-b and 15a-b) were evaluated for their antimicrobial potential against Gram positive (Staphylococcus aureus), and a set of Gram negative (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) bacterial strains and two fungi, Candida albicans and Cryptococcus neoformans. Antimicrobial studies revealed the comparable activities of benzimidazolium salts (6a-b and 11a-b) and the silver(I) complexes (12a-b, 13a-b and 15a-b). Whereas, the 1,3-dioxolane substituted benzimidazole-based silver(I) acetate complexes (14a-b) demonstrated excellent potentials with both bacterial and fungal growth inhibition above 95%.
