Copper(I) carbonyl and copper(II) acetato complexes with 2,2′-dipyridylamine and halide anions. Crystal and molecular structures of carbonylchloro(2,2′-dipyridylamine)copper(I) and acetatochloro(2,2′-dipyridylamine)copper(II)

Series of [Cu(I)dipyam(CO)X], [Cu(II)dipyam(CH3CO2)X] and [Cu(II) (dipyam)2(CH3CO2)]X complexes (dipyam = 2,2′-dipyridylamine; X = Cl(-), Br(-),I(-)) were synthesized and the structures of the title compounds were d etermined by X-ray diffraction methods. Crystallographic details for complexes [Cu(I)dipyam(CO)Cl] (1) and [Cu(II)dipyam(CH3CO2)Cl] (2) are as follows: complex 1, triclinic, space group P1- with a = 9.944(3), b = 9.450(3), c = 7.053(3)A, alpha = 69.50(2), beta = 91.81(2), gamma= 76.33(2)°, Z = 2; complex 2, triclinic, space group P1- with a = 10.093(3), b = 9.098(3), c = 7.444(2)A, alpha = 106.24(2), .bet a. = 96.91(2), gamma = 78.87(2)°, Z = 2. The dry carbonyl complexes are thermostable at 100°C or more, but their formation was reversible in solution even at room temperature. Thermal and chemical stabilities increase from the chloro to the iodo species. Among the acetatoderivatives the chloro and bromo mono-dipyam complexes were easily form ed, while the iodide gave preferentially the bis-dipyam complex. Each series of the complexes gave very similar IR spectra in the range 3800-250cm**-1. For the carbonyl derivatives the patterns of the far-IR 250-60 cm**-1 regions were shown and the nu(Cu-X) frequencies assigned.

Crown-linked dipyridylamino-triazine ligands and their spin-crossover iron(ii) derivatives: Magnetism, photomagnetism and cooperativity

The syntheses, crystallography and magnetic properties of a series of compounds of formula trans-[FeII(L1)2(NCX) 2] (X = S, Se, BH3 (1-3)), cis-[FeII(L 2)(NCX)2]·CH2Cl2 (X = S, Se, BH3 (4-6)) and trans-[FeII(L3)(NCX) 2]n (X = S, Se (7-8)) are described (L1 = 6-chloro-N2,N2-diethyl-N4,N4- di(pyridin-2-yl)-1,3,5-triazine-2,4-diamine, L2 = 6,6?-(1,4,10,13-tetraoxa-7,16-diazacyclooctadecane-7,16-diyl)bis(N 2,N2-diethyl-N4,N4-di(pyridin-2-yl)- 1,3,5-triazine-2,4-diamine, L3 = 6,6?-(1,4,10,13-tetraoxa-7,16- diazacyclooctadecane-7,16-diyl)bis(N2,N2,N 4,N4-tetra(pyridin-2-yl)-1,3,5-triazine-2,4-diamine)). The magnetostructural properties of 1-8 have been probed in detail by variable temperature magnetic measurements and crystallographic methods. 1-6 display mononuclear structures while 7 and 8 form 1-D chain structures. Complexes 4-6 have the potential to form 1D-chains via L2 bridging, but instead form mononuclear complexes. Magnetic studies show that complexes 1, 2, and 4 remain in the high-spin (HS) state at all temperatures. An aged, dry, powdered sample of 3 gives an abrupt HS to LS transition (T1/2 = 200 K), while a freshly prepared, powdered sample of 3·1.5H2O displays thermal hysteresis (Delta = 7 K). Complexes 5, 6 and 7 undergo a gradual spin transition with T1/2 values of 100 K, 150 K and 130 K, respectively. Cooperativity parameters are compared, with 3 showing cooperativity (positive C) and 5 and 6 showing anticooperativity. Photomagnetic LIESST (light induced excited spin state trapping) studies were performed on complexes 5 and 6 and reveal T(LIESST) values lower than 60 K. An attempt has been made to understand the electronic structure of complex 3 and its cooperativity behaviour using density functional methods, the calculations reproducing the sign and, in part, the magnitude of the cooperativity.

The role of glucuronidation in drug resistance

The final therapeutic effect of a drug candidate, which is directed to a specific molecular target strongly depends on its absorption, distribution, metabolism and excretion (ADME). The disruption of at least one element of ADME may result in serious drug resistance. In this work we described the role of one element of this resistance: phase II metabolism with UDP-glucuronosyltransferases (UGTs). UGT function is the transformation of their substrates into more polar metabolites, which are better substrates for the ABC transporters, MDR1, MRP and BCRP, than the native drug. UGT-mediated drug resistance can be associated with (i) inherent overexpression of the enzyme, named intrinsic drug resistance or (ii) induced expression of the enzyme, named acquired drug resistance observed when enzyme expression is induced by the drug or other factors, as food-derived compounds. Very often this induction occurs via ligand binding receptors including AhR (aryl hydrocarbon receptor) PXR (pregnane X receptor), or other transcription factors. The effect of UGT dependent resistance is strengthened by coordinate action and also a coordinate regulation of the expression of UGTs and ABC transporters. This coupling of UGT and multidrug resistance proteins has been intensively studied, particularly in the case of antitumor treatment, when this resistance is “improved” by differences in UGT expression between tumor and healthy tissue. Multidrug resistance coordinated with glucuronidation has also been described here for drugs used in the management of epilepsy, psychiatric diseases, HIV infections, hypertension and hypercholesterolemia. Proposals to reverse UGT-mediated drug resistance should consider the endogenous functions of UGT.

Application of multivariate curve resolution approaches to improve analytical separation of Iranian rice volatiles by GC-MS

Multivariate curve resolution (MCR) methods are proposed to improve the analysis of volatile components of an Iranian rice sample (Domsiah) by headspace sampling coupled to gas chromatography-mass spectrometry. A total of 31 components was identified using similarity searches between mass spectra and mass spectrometry database. Then extended multivariate curve resolution-alternating least squares (MCR-ALS) by applying proper constraints is used to obtain pure elution and mass spectral profiles for the components present in each peak cluster. The resolved components were identified by similarity searches using the NIST mass database and their percentage were calculated for qualitative and quantitative analysis, respectively. The number of identified components was extended to 82 by applying the MCR-ALS techniques. The main identified volatile chemicals that were found in an Iranian rice sample (Domsiah) were; nonanal (18.22%), hexanal (14.33%), 2-benzoyl-6,7-dimethoxy-4-methylidene-2H-1,3-benzothiazine (7.81%), epilophodione (7.023%), and 1-methyl-4-(1-methylethenyl)cyclohexene (6.61%).

Glycosyl triazoles as novel insect beta-N-acetylhexosaminidase OfHex1 inhibitors: Design, synthesis, molecular docking and MD simulations

The insect enzyme GH20 beta-N-acetyl-D-hexosaminidase OfHex1 represents an important chitinolytic enzyme found in the agricultural pest Ostrinia furnacalis (Guenee) and inhibition of this enzyme has been considered a promising strategy for the development of eco-friendly pesticides. In this article, based on the structure of the catalytic domains of OfHex1, a series of novel glycosyl triazoles were designed and synthesized via Cu-catalyzed azide-alkyne [3+2] cycloaddition reaction. To investigate the potency and selectivity of these glycosyl triazoles, the inhibition activities towards OfHex1 and HsHexB (human beta-N-acetylhexosaminidase B) were studied. Particularly compound 17c (OfHex1, Ki = 28.68 muM; HsHexB, Ki > 100 muM) exhibited a suitable activity and selectivity against OfHex1. Furthermore, the possible inhibitory mechanisms of 17c with OfHex1 were studied using molecular docking and MD simulations. The structure-activity relationship results as well as the formed binding patterns may provide promising insights into the further development of novel OfHex1 inhibitors.
