Betaine hydrochloride (BHC), as an ionic salt was found to be an efficient and recyclable catalyst for the one-pot synthesis of 4-thiazolidinediones. The methodology of study was achieved by one-pot condensation of aromatic aldehydes, aromatic amine and mercaptoacetic acid in the presence of betaine hydrochloride (BHC) at reflux temperature in ethanol as solvent. The efficiency of Betaine hydro...

The title compound, [Cu(C(12)H(13)BrNO)(2)], was prepared by the reaction of 5-bromo-salicylaldehyde, cyclo-pentyl-amine and copper(II) acetate in an ethanol solution. The Cu(II) atom lies on an inversion center and is four-coordinated in a square-planar geometry by two N and two O atoms from two 4-bromo-2-(cyclo-pentyl-imino-meth-yl)phenolate Schiff base ligands.

The title compound, C(10)H(11)I(2)NO, was prepared by the reaction of 3,5-diiodo-salicyl-aldehyde with propyl-amine in ethanol. The mol-ecule adopts an E conformation with respect to the C=N bond and the aromatic ring. The aromatic ring and the imino unit are close to being coplanar, with a dihedral angle of 2.6 (3)° between their planes. This planarity is assisted by the formation of an intra-...

In the title complex, [Mn(C(36)H(50)N(2)O(2))(CH(3)COO)(H(2)O)]·CH(3)CH(2)OH, the Mn(III) atom is in an octa-hedral environment and is coordinated by the tetra-dentate amine-bis-(phenolate) ligand, a monodentate acetate anion and a water mol-ecule. An ethanol solvent mol-ecule is also found in the asymmetric unit. The structure displays O-H⋯O and C-H⋯O hydrogen bonding.

A surface plasmon resonance (SPR) sensor was applied to analyses of some amine compounds (n-butylamine, isobutylamine, aniline, and N,N-dimethylaniline) by using a polymer film and an acid-base reaction in it. Poly(acrylamide) (PAA) was adopted as the polymer film and was immobilized on an Au film to prepare a sensor chip. Pivalic acid was entered into the PAA film as an acid. The PAA film with...

Sterol glucosyltransferase, Ugt51/Atg26, is essential for both micropexophagy and macropexophagy of methanol-induced peroxisomes in Pichia pastoris. However, the role of this protein in pexophagy in other yeast remained unclear. We show that oleate- and amine-induced peroxisomes in Yarrowia lipolytica are degraded by Atg26-independent macropexophagy. Surprisingly, Atg26 was also not essential f...

Heptamethine cyanine dyes are attractive compounds for imaging purposes in biomedical applications because of their chemical and photophysical properties exhibited in the nearinfrared region. A series of meso amino-substituted heptamethine cyanine dyes with indolenine, benz[e]indolenine and benz[c,d]indolenine heterocyclic moieties were synthesized and their spectral properties including fluore...
