Efficient production of red Monascus pigments with single non-natural amine residue by in situ chemical modification

Filamentous fungi Monascus sp. has been utilized for fermentative production of food colorant (Red Yeast Rice) for more than 1000?years in China. The main colorant components of Red Yeast Rice are mixture of red Monascus pigments (RMPs) with various primary amine residues. In the present work, the non-natural primary amine p-aminobenzamide, exhibiting as non-involved in nitrogen microbial metabolism, nontoxicity to microbial cells, and chemical reactivity with orange Monascus pigments (OMPs), was screened. Based on the screened result, RMPs with the single p-aminobenzamide residue were produced by cell suspension culture in a nonionic surfactant micelle aqueous solution via in situ chemical modification of OMPs. Furthermore, in situ chemical modification of OMPs also provided a strategy for maintaining a relatively low OMP concentration and then efficient accumulation of high concentration of RMPs (3.3?g/l).

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 126456-43-7, help many people in the next few years.Computed Properties of C9H11NO

Effects of steric/basic properties of Lewis bases on the degree of aggregation of zinc(II) pivalate complexes

A triangular [Zn3(mu3-OH)(OC(O)tBu) (mu2-kappa1O:kappa1O?-O 2CtBu)4(3,5-lutidine)3] (1), a paddlewheel based dinuclear [Zn(mu2-kappa1O: kappa1O?-O2CtBu)2L] 2 [L = 2,4-lutidine (2), 3,4-lutidine (3), and 2,3-lutidine (4)] and an hourglass based linear trinuclear [Zn3(mu2- kappa1O:kappa1O?-O2C tBu)6(pyridine)2] (5) complexes were synthesized to understand the role of subtle steric/basic properties of Lewis bases on the degree of aggregation of the products. The mononuclear Zn(OC(O)tBu)2¡¤2H2O was also prepared in order to probe the origin of the mu3-OH moiety in complex 1. Complexes 1-5 and Zn(OC(O)tBu)2¡¤2H2O were characterized by microanalytical, IR, TGA/DTA, solution (1H and 13C) NMR, solid-state cross-polarization magic angle spinning (CP-MAS) 13C NMR, mass spectral data and single crystal X-ray diffraction data. Complex 1 represents the first example of a discrete trinuclear zinc(II) carboxylate complex that contains a [Zn3(mu 3-OH)]5+ core with zinc atoms in three distinct geometries namely a distorted tetrahedral, trigonal bipyramidal, and octahedral. A plausible mechanism for the formation of complexes 1-5 was explained with the aid of point zero charge (pzc) model.

Quantum chemical study of the inhibition properties of pyridine and its derivatives at an aluminum surface

A quantum chemical study of the corrosion inhibition properties of pyridine and its derivatives at the aluminum electrode in hydrochloric acid was carried out. Based on the calculated results the compounds were adsorbed on the metal surface mainly in their protonated forms. The models of the inhibitors adsorption on the Al-surface were optimized with the MNDO method. It is found that the most favorable model is that the inhibitor molecule is adsorbed at the Al-surface in an inclined state, and the electron of the Al-surface is transferred to the inhibitor. The co-adsorption of the inhibitor and Cl- and H(ads) was discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.

Effective methodologies for enantiomeric separations of 150 pharmacology and toxicology related 1 2 and 3 amines with core-shell chiral stationary phases

Core-shell particles (superficially porous particles, SPPs) have been proven to provide high-throughput and effective separations of a variety of chiral molecules. However, due to their limited commercialization, many separations have not been reported with these stationary phases. In this study, four SPP chiral stationary phases (CSPs) were utilized for the enantiomeric separation of 150 chiral amines. These amines encompass a variety of structural and drug classes, which are particularly important to the pharmaceutical industry and in forensics. This comprehensive evaluation demonstrates the power of these CSPs and the ease of method development and optimization. The CSPs used in this study included the macrocyclic glycopeptide-based CSPs (VancoShell and NicoShell), the cyclodextrin-based CSP (CDShell-RSP), and the cyclofructan-based CSP (LarihcShell-P). These CSPs offered versatility for a variety of applications and worked in a complementary fashion to baseline separate all 150 amines. The LarihcShell-P was highly effective for separating primary amines. VancoShell, NicoShell, and CDShell-RSP were useful for separating all types of amines. These CSPs are multi-modal and can be utilized with mass spectrometry compatible solvents. Eighteen racemic controlled substances were simultaneously baseline separated in a single liquid chromatography?mass spectrometry (LC?MS) analysis. Details in high-performance liquid chromatography (HPLC) parameters will be discussed as well as the improved chromatographic performance afforded by the SPP CSPs.
