Condensations of stabilized phosphorane 1 with 3-substituted phthalic anhydrides were investigated.The importance of various effects influencing regio- and stereoselectivity of these reactions is discussed.It is proposed that the oxygen atom on the substituents in position 3 can act as a Lewis base toward the electron-deficient phosphorus of the ylid.The resulting complexation stabilizes the transition state for the reacction at the ortho carbonyl group, thus offsetting the usual steric and “push” effects, wich favour attack at the meta carbonyl function. – Key words: Wittig condensations, phthalic anhydrides, regioselectivity, stereoselectivity.

Phenotypic HTS campaigns with a blood stage malaria assay have been used to discover novel chemotypes for malaria treatment with potential alternative mechanisms of action compared to existing agents. N1-(5-(3-Chloro-4-fluorophenyl)furan-2-yl)-N3,N3-dimethylpropane-1,3-diamine, 1 was identified as a modest inhibitor of P. falciparum NF54 (IC50= 875 nM) with an apparent long plasma half-life after high dose oral administration to mice, although the compound later showed poor metabolic stability in liver microsomes through ring- and side chain-oxidation and N-dealkylation. We describe here the synthesis of derivatives of 1, exploring the influence of substitution patterns around the aromatic ring, variations on the alkyl chain and modifications in the core heterocycle, in order to probe potency and metabolic stability, where 4k showed a long half-life in rats.

High resolution fluorine-19 NMR spectra of polyfluoroaromatic compounds dissolved in deuterated dimethyl sulphoxide were measured and substituent shielding parameters were derived.These parameters were compared with the values observed in deuterated chloroform solutions and used to identify fluoroaromatic compounds related to perfluorinated polyimides and poly(amic acids)s.Average differences of Deltadelta between the solvents are 1.1, 1.0 and 2.1 ppm for o-, m- and p-fluorines of monosubstituted pentafluorobenzenes, respectively.The significant difference for p-fluorine of NH2 is important in identifying perfluorinated diamines because they are source materials for perfluorinated polyimides.Substituent shielding parameters for meta and para substitution increase as the respective Hammett ? constants increase, which indicates that fluorine-19 NMR chemical shift is primarily determined by electron density. – Keywords: NMR; 19F NMR; substituent shielding parameter; fluoroaromatic compounds; perfluorinated polyimides; Hammett ? constant

The therapeutic potential of selective mGlu1 activation is vastly unexplored relative to the other group I mGlu receptor, mGlu5; therefore, our lab has focused considerable effort toward developing mGlu1 positive allosteric modulators (PAMs) suitable as in vivo proof of concept tool compounds. Optimization of a series of mGlu1 PAMs based on an N-(3-chloro-4-(1,3-dioxoisoindolin-2-yl)phenyl)-3-methylfuran-2-carboxamide scaffold provided 17e, a potent (mGlu1 EC50 = 31.8 nM) and highly CNS penetrant (brain to plasma ratio (Kp) of 1.02) mGlu1 PAM tool compound, that potentiated not only wild-type human mGlu1 but also mutant mGlu1 receptors derived from deleterious GRM1 mutations found in schizophrenic patients. Moreover, both electrophysiological and in vivo studies indicate the mGlu1 ago-PAMs/PAMs do not possess the same epileptiform adverse effect liability as mGlu5 ago-PAMs/PAMs and maintain temporal activity suggesting a broader therapeutic window.

In recent years, oil and grease has been identified as an emerging pollutant of concern (EPC) in wastewater stream as it can disturb the ecology and wastewater treatment process efficiency. The highest contributor to oily wastewater among domestic wastewater is from kitchen greywater. One of the alternatives to address this problem is the application of enzyme. The production of enzyme by using organic waste has gained significant attention in the recent years due to sustainable demand from it. In this study, pectinolytic enzyme was produced through simplified fermentation from discarded citrus peels that possess high lipase content. Three batches of treatment which consist of the control sample (solely wastewater), 25% (v/v) citrus enzyme + wastewater and 50% (v/v) citrus enzyme + wastewater was incubated in an incubator shaker for 10 days at 30 C and 150 rpm. The wastewater analysis was performed at a regular interval of 48 h. The parameters monitored were pH, BOD5 and oil and grease. Laboratory work has demonstrated that 25% (v/v) pectinolytic enzyme was able to remove BOD5 and oil and grease about 10% better than 50% (v/v) pectinolytic enzyme. The percentage of removal achieved by 25% (v/v) pectinolytic enzyme was 39.83 ± 9.50 mg/L and 64.21 ± 1.12 mg/L, respectively. However, it was observed that enzyme was less effective in removing BOD5 as the solution contains organic matter that increases the total organic matter in the wastewater mixture.

A set of two broadly applicable procedures for the N-arylation of hydantoins is reported. The first one relies on the use of stoichiometric copper(I) oxide under ligand- A nd base-free conditions and enables a clean regioselective arylation at the N3 nitrogen atom, while the second one is based on the use of catalytic copper(I) iodide and trans-N,N?-dimethylcyclohexane-1,2-diamine and promotes arylation at the N1 nitrogen atom. Importantly, the combination of these two procedures affords a straightforward entry to diarylated hydantoins.

An asymmetric palladium-catalyzed intramolecular oxidative aminoarylation of alkenes has been developed with quinoline?oxazoline chiral ligands and Ag2CO3 as the oxidant. Various indolines containing a quaternary stereogenic center were synthesized in high yield with excellent enantioselectivity. Preliminary mechanistic studies suggest that the addition of a catalytic amount of phenylglyoxylic acid significantly accelerates the reaction and slightly enhances the enantioselectivity.

Myeloid cell leukemia 1 (Mcl-1), a member of the Bcl-2 family of proteins, is overexpressed and amplified in various cancers and promotes the aberrant survival of tumor cells that otherwise would undergo apoptosis. Here we describe the discovery of potent and selective Mcl-1 inhibitors using fragment-based methods and structure-based design. NMR-based screening of a large fragment library identified two chemically distinct hit series that bind to different sites on Mcl-1. Members of the two fragment classes were merged together to produce lead compounds that bind to Mcl-1 with a dissociation constant of <100 nM with selectivity for Mcl-1 over Bcl-xL and Bcl-2. Structures of merged compounds when complexed to Mcl-1 were obtained by X-ray crystallography and provide detailed information about the molecular recognition of small-molecule ligands binding Mcl-1. The compounds represent starting points for the discovery of clinically useful Mcl-1 inhibitors for the treatment of a wide variety of cancers. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 496-41-3, help many people in the next few years.name: Benzofuran-2-carboxylic acid
