The first Suzuki-Miyaura cross-coupling reactions of the synthetically versatile aryl O-carbamate and O-sulfamate groups are described. The transformations utilize the inexpensive, bench-stable catalyst NiCl 2(PCy3)2 to furnish biaryls in good to excellent yields. A broad scope for this methodology has been demonstrated. Substrates with electron-donating and electron-withdrawing groups are tolerated, in addition to those that possess ortho substituents. Furthermore, heteroaryl substrates may be employed as coupling partners. A computational study providing the full catalytic cycles for these cross-coupling reactions is described. The oxidative addition with carbamates or sulfamates occurs via a five-centered transition state, resulting in the exclusive cleavage of the aryl C-O bond. Water is found to stabilize the Ni-carbamate catalyst resting state, which thus provides rationalization of the relative decreased rate of coupling of carbamates. Several synthetic applications are presented to showcase the utility of the methodology in the synthesis of polysubstituted aromatic compounds of natural product and bioactive molecule interest.

Hydrolytic enzymes constitute one of the largest and most diverse protein classes in Nature and play key roles in nearly all physiological and pathological processes. The mammalian serine hydrolase superfamily contains a remarkable number of uncharacterized members, with at least 40-50% of these enzymes lacking experimentally verified endogenous substrates and products. Assignment of metabolic and cellular functions to these enzymes requires the development of pharmacological tools to selectively perturb their activity. We describe herein a functional proteomic strategy to systematically develop potent and selective inhibitors for uncharacterized serine hydrolases and its application to the brain-enriched enzyme alpha/beta-hydrolase-6. We anticipate that the methods described herein will facilitate the development of selective chemical probes to annotate the metabolic and (patho)physiological functions of many of the uncharacterized serine hydrolases that currently populate eukaryotic and prokaryotic proteomes.

An area of shore on Laysan Island in the Hawaiian Islands National Wildlife Refuge has been observed over the last 10 years to cause mortality to several species of birds, crabs, and insects which come into contact with the sand. Previous analysis of two composite samples from 1993 and 1997 indicated contamination of carbofuran in the sand at levels in the low mug/g range. In November of 1997, and July and October of 1998, 129 additional samples were collected in order to define the extent of the carbofuran contamination. Sand samples were extracted with acetone in a pressurized fluid extractor and analyzed by GC-MS. Localized contamination was present at 1,639 mug/g of carbofuran and over 8,832 mug/g of its primary breakdown product, carbofuran-7-phenol. In addition to carbofuran-7-phenol, four other known transformation products were observed in sample extracts, including 3-hydroxy carbofuran, 3-keto carbofuran, 3-keto carbofuran phenol, and carbofuran diol. Two additional compounds which have not been previously reported as carbofuran breakdown products were also found. Spectra are presented and structures are proposed for these two compounds. The structure of one compound, carbofuran acetate, was confirmed by synthesis and GC/MS. To assess relative toxicity, Microtox bioassays were conducted for standards of carbofuran, 3-hydroxy carbofuran, and carbofuran-7-phenol, as well as for water extracts of native contaminated and clean sand. These assays supported the conclusion that the toxicity at the site can be explained by the presence of carbofuran and its products.

To clarify the properties of pesticide transformation products (TPs) for which the risk to aquatic organisms should be evaluated, I monitored the concentrations of paddy pesticides and their TPs in the Sakura River, Japan, during the rice-growing season in 2007-2010. I also conducted algal growth inhibition tests of herbicides and their TPs using a diatom and a green alga and acute toxicity tests of insecticides and their TPs using a caddisfly and a daphnid. Moreover, on the basis of the results of pesticide monitoring and toxicity tests, I attempted to evaluate the risk of these compounds to the riverine organisms as well as the risk of mixtures of insecticides and their TPs for caddisflies and cladocerans. The TPs were detected in the river water depending on the half-lives of the parent compounds and of the TPs in water and soil. The toxicities of the parent compound and its TPs may be related to their hydrophobicities and chemical structures. Some toxic and persistent TPs that formed rapidly in water and soil posed a risk to the organisms over a long period. The physicochemical properties and chemical structures of a parent compound and its TPs can be key factors in evaluating the pesticide TP risk to aquatic organisms in rivers.

Carbofuran-mineralizing strain Novosphingobium sp. KN65.2 produces the CfdJ enzyme that converts the N-methylcarbamate insecticide to carbofuran phenol. Purified CfdJ shows a remarkably low KM towards carbofuran. Together with the carbaryl hydrolase CehA of Rhizobium sp. strain AC100, CfdJ represents a new protein family with several uncharacterized bacterial members outside the proteobacteria. Although both enzymes differ by only four amino acids, CehA does not recognize carbofuran as a substrate whereas CfdJ also hydrolyzes carbaryl. None of the CfdJ amino acids that differ from CehA were shown to be silent regarding carbofuran hydrolytic activity but one particular amino acid substitution, i.e., L152 to F152, proved crucial. CfdJ is more efficient in degrading methylcarbamate pesticides with an aromatic side chain whereas CehA is more efficient in degrading the oxime carbamate nematicide oxamyl. The presence of common flanking sequences suggest that the cfdJ gene is located on a remnant of the mobile genetic element Tnceh carrying cehA. Our results suggest that these enzymes can be acquired through horizontal gene transfer and can evolve to degrade new carbamate substrates by limited amino acid substitutions. We demonstrate that a carbaryl hydrolase can gain the additional capacity to degrade carbofuran by a single nucleotide transversion.

6-Chloro-2-benzoxazolinone (CDHB) is a precursor of herbicide, insecticide, and fungicide synthesis and has a broad spectrum of biological activity. Pigmentiphaga sp. strain DL-8 can transform CDHB into 2-amino-5-chlorophenol (2A5CP), which it then utilizes as a carbon source for growth. The CDHB hydrolase (CbaA) was purified from strain DL-8, which can also hydrolyze 2-benzoxazolinone (BOA), 5-chloro-2-BOA, and benzamide. The specific activity of purified CbaA was 5,900 U . mg protein-1 for CDHB, with Km and kcat values of 0.29mMand 8,500 s-1, respectively. The optimal pH for purified CbaA was 9.0, the highest activity was observed at 55C, and the inactive metal-free enzyme could be reactivated by Mg2+, Ni2+, Ca2+, or Zn2+. Based on the results obtained for the CbaA peptide mass fingerprinting and draft genome sequence of strain DL-8, cbaA (encoding 339 amino acids) was cloned and expressed in Escherichia coli BL21(DE3). CbaA shared 18 to 21% identity with some metal-dependent hydrolases of the PF01499 family and contained the signature metal-binding motif Q127XXXQ131XD133XXXH137. The conserved amino acid residues His288 and Glu301 served as the proton donor and acceptor. E. coli BL21(DE3-pET-cbaA) resting cells could transform 0.2mMCDHB into 2A5CP. The mutant strain DL-8DeltacbaA lost the ability to degrade CDHB but retained the ability to degrade 2A5CP, consistent with strain DL-8. These results indicated that cbaA was the key gene responsible for CDHB degradation by strain DL-8.

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.Product Details of 1563-38-8, you can also check out more blogs about1563-38-8
