The first potent inhibitors of glutamate racemase (MurI) enzyme that show whole cell antibacterial activity are described. Optically pure 4-substituted D-glutamic acid analogues with (2R,4S) stereochemistry and bearing aryl-, heteroaryl-, cinnamyl-, or biaryl-methyl substituents represent a novel class of glutamate racemase inhibitors. Exploration of the D-Glu core led to the identification of lead compounds (-)-8 and 10. 2-Naphthylmethyl derivative 10 was found to be a potent competitive inhibitor of glutamate racemase activity (Ki = 16 nM, circular dichroism assay; IC50 = 0.1 mug/mL high-performance liquid chromatography (HPLC) assay). Thorough structure-activity relationship (SAR) studies led to benzothienyl derivatives such as 69 and 74 with increased potency (IC50 = 0.036 and 0.01 mug/mL, respectively, HPLC assay). These compounds showed potent whole cell antibacterial activity against S. pneumoniae PN-R6, and good correlation with the enzyme assay. Compounds 69, 74 and biaryl derivative 52 showed efficacy in an in vivo murine thigh infection model against Streptococcus pneumoniae. Data described herein suggest that glutamate racemase may be a viable target for developing new antibacterial agents.

A series of N-(2-(1H-imidazol-1-yl)-2-phenylethyl)arylamides were prepared, using an efficient three- to five-step synthesis, and evaluated for their inhibitory activity against human cytochrome P450C24A1 (CYP24A1) hydroxylase. Inhibition ranged from IC50 0.3-72 muM compared with the standard ketoconazole IC50 0.52 muM, with the styryl derivative (11c) displaying enhanced activity (IC50 = 0.3 muM) compared with the standard, providing a useful preliminary lead for drug development.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzofuran, you can also check out more blogs about69604-00-8

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Application In Synthesis of Benzofuran-7-ol, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4790-81-2, Name is Benzofuran-7-ol, molecular formula is C8H6O2

RATIONALE Multi-residue determination of pesticides in a complex matrix by online gel permeation chromatography-gas chromatography/mass spectrometry (GPC-GC/MS) is increasingly concerned for its high throughput, efficiency and accuracy. Study of matrix-induced suppression or enhancement of the instrument signals is important for the application of this technique. METHODS Matrix suppression and enhancement effects for 176 pesticides were studied by online GPC-GC/MS and post-extraction addition. Suppression effects induced by co-eluted compounds were examined in the matrices tea and human breast milk. The prepared matrix was studied to confirm the results by deliberate addition of phthalates or caffeine to the matrix of Chinese cabbage. RESULTS Both suppression and enhancement effects induced by co-eluted matrix were found. The different results may depend on the concentration of the matrix. Enhancement effects for carbamate and polar pesticides were found because of the blocking of active sites in the instrument by the large volume injection (LVI) technique combined with on-column and programmed temperature vaporization (PTV) mode. The results can explain the significant difference in instrument signals between isomers or native and isotope labels in some matrices. CONCLUSIONS Online GPC-GC/MS with combined PTV and on-column LVI mode is presumed to be applicable for the multi-residue method including the studied pesticides if calibrated by matrix-matched standards. However, further cleanup steps should be deloped to remove co-eluted matrix if remarkable suppression effects are found. Copyright

Two ruthenium(II) complexes [Ru(bpy)2(bfipH)]2+ (1) and [Ru(phen)2(bfipH)]2+ (2) have been synthesized and characterized. The DNA-binding behaviors of complexes were studied by using spectroscopic and viscosity measurements. Results suggested that the two complexes bind to DNA in an intercalative mode. Complexes 1 and 2 can efficiently photocleave pBR322 DNA in vitro under irradiation, singlet oxygen (1O2) was proved to contribute to the DNA photocleavage process. Topoisomerase inhibition and DNA strand passage assay confirmed that two Ru(II) complexes acted as efficient dual inhibitors of topoisomerases I and II. In MTT cytotoxicity studies, two Ru(II) complexes exhibited antitumor activity against BEL-7402, HeLa, MCF-7 tumor cells. The AO/EB staining assay indicated that Ru(II) complexes could induce the apoptosis of HeLa cells.

An array of hybrid catalysts incorporating a chloramphenicol base moiety linked to another chiral scaffold through a squaramide linker were developed and successfully used in the Michael addition of 2,3-dihydrobenzofuran-2-carboxylates to nitroolefins. Control experiments suggested that the hybrid catalysts were more reactive than nonhybridized bifunctional catalysts, and matching of the chirality between the two scaffolds was crucial for high reactivity and stereoselectivity. These hybrid organocatalysts could be used with a variety of substrates. At a 0.5 mol-% catalyst loading, a range of 2,3-dihydrobenzofuran-2-carboxylates derivatives bearing quaternary and tertiary stereogenic centers were obtained in high yields (up to 98 %) with excellent enantioselectivities (up to 99 % ee) and moderate diastereoselectivities (up to 8:92 dr).

A new type of chiral sulfonium salts that are characterized by a bicyclic system has been designed and synthesized from alpha-amino acids. Their corresponding ylides, which were prepared by basic treatment of the sulfonium salts, reacted smoothly with a broad array of simple and chiral aldehydes to provide trans-epoxy amides in reasonable to very good yields and excellent stereoselectivities (>98 %). The obtained epoxy amides were found to be useful as synthetic building blocks. Thus, they were reduced into their corresponding epoxy alcohols and subjected to oxirane-ring-opening reactions with different types of nucleophiles.
