Nanduri, V. V. S. S. Raman published the artcileDevelopment and Validation of Stability-Indicating HPLC and UPLC Methods for the Determination of Bicalutamide, Product Details of C18H14F4N2O4S, the main research area is bicalutamide impurity determination HPLC UPLC tablet stability.

Six new process related impurities (Imp-08, Imp-09, Imp-10, Imp-12, Imp-13, and Imp-14) of bicalutamide (BCT) were reported in this paper. BCT was subjected to oxidative, acid, alk., hydrolytic, thermal, and photolytic degradation conditions and found to degrade in alk. condition, yielding Imp-11. Stability-indicating high-performance liquid chromatog. and ultra-performance liquid chromatog. methods were developed for the determination of BCT in the presence of its 14 process-related impurities and 1 degradant by Zorbax SB Ph column (150 × 4.6 mm × 3.5 μm) and HSS T3 column (100 × 2.1 mm × 1.8 μm), resp. Both the methods were validated as per International Conference on Harmonization guidelines. Quantitation limits (QL) were found be in the ranges of 0.02-0.03% for both the methods. Precision was evaluated by replicate anal. in which % relative standard deviation (RSD) values for areas were found <2.0. Linearity for the impurities was established in the range of QL to 200% of the specification level and the correlation coefficients derived from of the resp. calibration curves were approx. 0.999. The recoveries obtained for purity (90-100%) and assay (98-102%) ensured the accuracy of the developed methods.

Sadutto, Daniele published the artcileAnalytical and semipreparative high performance liquid chromatography enantioseparation of bicalutamide and its chiral impurities on an immobilized polysaccharide-based chiral stationary phase, Name: N-(4-Cyano-3-(trifluoromethyl)phenyl)-3-((2-fluorophenyl)sulfonyl)-2-hydroxy-2-methylpropanamide, the main research area is liquid chromatog enantioseparation bicalutamide chiral impurity polysaccharide; Bicalutamide; Chiralpak IA; Enantiomers; Impurities; Semipreparative resolution; Temperature-variable HPLC.

Direct HPLC separation of enantiomers of Bicalutamide (BCT), a non-steroidal antiandrogen used for the treatment of prostate cancer, was performed by using the immobilized amylose-based Chiralpak IA chiral stationary phase (CSP). Enantioselective conditions were achieved using standard normal phase mixtures n-hexane-alc. (ethanol or 2-propanol) and a “”non-standard”” mobile phase containing Et acetate (EA). The chromatog. behavior of the IA CSP under these elution modes was evaluated and compared at different temperatures The eluent mixture n-hexane-EA-ethanol 100-30-5 (volume/volume/v) and the column temperature of 40 °C were identified as the best operational conditions to carry out semipreparative enantioseparations on a 1-cm I. D. IA column. Using this protocol, about 960 mg of (R)-BCT, which is the enantiomer with the almost entire anti-androgenic activity of BCT, per day could be isolated. The anal. and semipreparative HPLC resolution of chiral impurities of BCT, and their empiric absolute configuration assignment by CD correlation method are also presented.

Current pharmacological management of Parkinson disease (PD) does not provide for disease modification, but addresses only symptomatic features. Here, we explore a new approach to neuroprotection based on the use of 2-pentadecyl-2-oxazoline (PEA-OXA), the oxazoline derivative of the fatty acid amide signaling molecule palmitoylethanolamide (PEA), in an experimental model of PD. Daily oral treatment with PEA-OXA (10mg/kg) significantly reduced behavioral impairments and neuronal cell degeneration of the dopaminergic tract induced by four intraperitoneal injections of the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on 8-week-old male C57 mice. Moreover, PEA-OXA treatment prevented dopamine depletion, increased tyrosine hydroxylase and dopamine transporter activities, and decreased -synuclein aggregation in neurons. PEA-OXA treatment also diminished nuclear factor-B traslocation, cyclooxygenase-2, and inducible nitric oxide synthase expression and through upregulation of the nuclear factor E2-related factor 2 pathway, induced activation of Mn-superoxide dismutase and heme oxygenase-1. Further, PEA-OXA modulated microglia and astrocyte activation and preserved microtubule-associated protein-2 alterations. In conclusion, pharmacological activation of nuclear factor E2-related factor 2 pathways with PEA-OXA may be effective in the future therapy of PD.

The controlled release of well-defined radical species under mild conditions for subsequent use in selective reactions is an important and challenging task in synthetic chemistry. We show here that simple bismuth amide species [Bi(NAr2)(3)] readily release aminyl radicals [NAr2](.) at ambient temperature in solution. These reactions yield the corresponding hydrazines, Ar2N-NAr2, as a result of highly selective N-N coupling. The exploitation of facile homolytic Bi-Pn bond cleavage for Pn-Pn bond formation was extended to higher homologues of the pnictogens (Pn=N-As): homoleptic bismuth amides mediate the highly selective dehydrocoupling of HPnR(2) to give R(2)Pn-PnR(2). Analyses by NMR and EPR spectroscopy, single-crystal X-ray diffraction, and DFT calculations reveal low Bi-N homolytic bond-dissociation energies, suggest radical coupling in the coordination sphere of bismuth, and reveal electronic and steric parameters as effective tools to control these reactions.

Application of 135-57-9, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 135-57-9 is helpful to your research.

Background: Water evaporation in solar salterns creates salinity gradients that promote the adaptation of microbial species to different salinities. This competitive habitat challenges the metabolic capabilities of microorganisms and promotes alterations in their production of secondary metabolites. Thus, solar salterns are a potentially important source of new natural products. In Colombia, the most important and representative solar saltern is located in Manaure (La Guajira) in the north of Colombia. The aim of this study was to develop an alternative screening strategy to select halophilic bacteria as producers of bioactive compounds from mixed microbial cultures rather than individual environmental isolates. Brine and sediment samples from different ponds (across a salinity gradient) were inoculated in seven different culture media to grow bacteria and archaea, allowing for a total of 40 different mixed cultures. An organic extract from each mixed culture was obtained and tested against multidrug resistant pathogens, including Klebsiella pneumoniae, vancomycin-resistant Enterococcus faecium, methicillin-resistant Staphylococcus aureus and Bacillus subtilis. In addition, the extracts were tested against two human cancer cell lines, cervical adenocarcinoma (SiHa) and lung carcinoma (A-549). Results: Twenty-four of the forty extracts from mixed cultures obtained from brine and sediment samples from the Manaure solar saltern showed antibacterial activity against Bacillus subtilis. Two extracts, referred to as A1SM3-29 and A1SM3-36, were also active against a methicillin-resistant Staphylococcus aureus, with the latter extract also showing slight cytotoxic activity against the assayed human lung cancer cell line. From this mixed culture, nine isolates were cultivated, and their extracts were tested against the same pathogens, resulting in the identification of a Vibrio sp. strain (A1SM3-36-8) with antimicrobial activity that was similar to that observed for the mixed culture extract. The extract of this strain was subjected to a bioautography assay, and 3 different fractions exhibited antibacterial activity against methicillin-resistant Staphylococcus aureus. Based on the amount obtained for each fraction, F3 was selected to isolate and identify its metabolites. The major compound was identified by NMR and HRMS as 13-cis-docosenamide, an amide that has been previously reported to be an antimicrobial and cytotoxic compound. Conclusions: Our results shows the utility of our strategy in detecting bioactive molecules in initial mixed cultures by biological assays, resulting in the isolation and characterization of Vibrio sp. A1SM3-36-8, a halophilic strain with great antibacterial and cytotoxic potential.

The enantioselective functionalization of nonactivated enantiotopic secondary C-H bonds is one of the greatest challenges in transition-metal-catalyzed C-H activation proceeding by an inner-sphere mechanism. Such reactions have remained elusive within the realm of Pd-0 catalysis. Reported here is the unique reactivity profile of the IBiox ligand family in the Pd-0-catalyzed intramolecular arylation of such nonactivated secondary C-H bonds. Chiral C-2-symmetric IBiox ligands led to high enantioselectivities for a broad range of valuable indane products containing a tertiary stereocenter, as well as the arylation of secondary C-H bonds adjacent to amides. Depending on the amide substituents and upon control of reaction time, indanes containing labile tertiary stereocenters were also obtained with high enantioselectivities. Analysis of the steric maps of the IBiox ligands indicated that the level of enantioselectivity correlates with the difference between the two most occupied and the two less occupied space quadrants, and provided a blueprint for the design of even more efficient ligands.

Synthetic polymers exhibiting reversible lower critical solution temperature (LCST), such as poly(N-iso-propylacrylamide) (PNIPAM), are intriguing materials with various potential applications. We recently developed a new class of biodegradable thermoresponsive polyesters (TR-PEs) based on N-substituted diol monomers. TR-PEs exhibited reversible cloud point temperatures (Tcp) between 0-50 degrees C and were shown to be non-cytotoxic. The synthesis of N-substituted diols and TR-PEs is highly modular, allowing for a wide variety of possible homo-and copolyesters. In this work, we report the synthesis and characterization of 20 homopolyesters in order to better understand the structure-property relationship of TR-PEs. UV-vis spectroscopy showed that the Tcp of TR-PEs was highly dependent on pendant group structure, such as secondary or tertiary amides, cyclic and linear groups, and substitution of oxygen atoms. Structure-Tcp analysis provides a correlation between Tcp and the number of heteroatoms relative to the number of carbon atoms in the pendant group thereby providing a rationale for the design of thermoresponsive polyesters with desired Tcp values. To demonstrate the expanded tunability of the TR-PE system, copolyesters bearing covalently attached ibuprofen were synthesized and shown to exhibit LCST behavior dependent on comonomer hydrophilicity.

In phytosynthesis of gold nanoparticles (AuNPs), biomolecules play a vital role in biocapping the surface of particles and generating the electrostatic repulsive forces to inhibit their growth kinetics. However, estimation of bioactive compounds influencing their surface characteristics through formation of electric repulsive forces (Velecdocumentclass), Van der Waals attraction forces (Vvdw) and ultimately hindering their growth is still in the phase of obscurity. Current study, based on surface chemistry approach has been performed for identification of bioactive compounds in Elaeis guineensis leaves (EGL/OPL), acting as biocapping agents and directing the growth of AuNPs over a period of time. The quantitative estimation of interparticle interactions and modification in Ostwald ripening (MOR) model were also done to correlate the growth kinetic of AuNPs. The X-ray photoelectron spectroscopy (XPS) showed the major contribution of oxygen, carbon and nitrogen elements, corresponding to polyphenolic, carboxylic and amides, in biocapping the surface of AuNPs and directing their interparticle interactions associated with growth kinetics. The Velec forces were reduced with an enhancement in the Vvdwforces, depicting their major role in impeding growth of AuNPs. The MOR model exhibited an excellent agreement of predicted growth with experimental size enlargements of AuNPs, having 4.8% average absolute relative percentage error.
