N,N-bis(carboxymethyl)-1-adamantylamine acid (H2BCAA) or N-(1-adamantyl)-iminodiacetic acid forms zwitterions that are intra-stabilized by a ‘bifurcated’ N+-H…O(carboxyl)2 interaction. In the crystal, both half-protonated carboxyl groups of H2BCAA ¡À are involved in linear O-H…O intermolecular bridges of 2.46 A. In the studied BCAA-CuII derivatives, the iminodiacetate-moiety of the BCAA chelating ligand exhibits a mer-NO2 conformation in [Cu(BCAA)(H2O)2] (1) and [Cu(BCAA)(Him)]2 (2), but fac-O2+N(apical) conformation in Cu(BCAA)(bpy)(H2O)]¡¤3.5H2O (3) [Him = imidazole, bpy =2,2?-bipyridine]. In clear contrast, dipyridylamine (dpya), as auxiliary ligand, seems to be unable to promote the fac-O2+N(apical) conformation in BCAA, as reveal the structures of two new salts with the trinuclear cation [(dpya)2Cu-mu2-Cu(BCAA) 2-Cu(dpya)2]2+ and the anions [Cu(BCAA) 2]2- (4) or NO3- (5), respectively.

In the ionic title compound, [Ni(NO3)(C10H9N3)2]NO3, the central NiII atom exhibits cis-NiN4O2 octahedral coordination with three chelating ligands, viz. one nitrate anion and two di-2-pyridylamine (dpya) molecules. A second nitrate group acts as a counter-ion. The complex cations and the nitrate anions are also linked by N – H…O hydrogen bonds. The compound was prepared in two different reproducible ways: direct synthesis from Ni(NO3)2 and dpya yielded systematically twinned crystals (the twinning law is discussed), while single crystals were obtained unexpectedly from the Ni(NO3)2/dpya/maleic acid/NaOH system.

Introduction: Orally disintegrating tablets (ODTs) provide an important treatment option for pediatric, geriatric and psychiatric patients. In our previous study, we have performed the initial studies for the formulation development and characterization of new ODT formulations containing a bitter taste drug, mirtazapine, coated with 6% (w/w) Eudragit E-100 (first group of formulations, FGF) without taste evaluation. In present study, coating ratio of the drug was increased to 8% (w/w) (second group of formulations, SGF) to examine the effect of increased coating ratio of drug on in vitro characterization of the formulations including in vitro taste masking study. Materials and methods: Coacervation technique using Eudragit E-100 was employed to obtain taste-masked mirtazapine granules. FGF and SGF were compared to original product (Remeron SolTab, an antidepressant drug which produced by pellet technology) in terms of in vitro permeability, in vitro taste masking efficiency which was performed by dissolution studies in salivary medium and dissolution stability. Also, the other tablet characteristics (such as diameter, thickness) of SGF were examined. Results and discussion: The disintegration time of the SGF were found as A1 < A2 < A3 < A5 < A4 (8% Eudragit E-100), but all of the formulations dissolved under 30 seconds and friability values were less than 1%. In vitro taste masking efficiency studies demonstrated that C2 formulation (in FGF) had the most similar dissolution profile to Remeron SolTab. Conclusions: According to these findings, B2 or C2 (with citric acid or sodium bicarbonate, respectively, with 6% Eudragit E-100) formulations could be promising alternatives to Remeron SolTab.

The (2-Py)2N- ligand shows much more conformational freedom than the (2-Py)2P- anion in aluminium coordination. The two isomers [Al{(NPy)Py}3] (1a) and [Al{(NPy)Py}2(Py2N)] (1b) were isolated, the former containing exclusively cistrans ligands, and the latter cis-trans ligands together with a trans-trans ligand. The energy differences in the noncoordinated anions (2-Py)2E- (E = N, P) were determined by computational methods to be low in the amide. While the N?Al donor bond energy is appreciable (96 kJ/mol), that of the P?Al donor bond is much lower (45 kJ/mol). This explains why the P-analogous donor-acceptor complex to Et2Al (2- Py)2N?AlEt3 could never be isolated. The P-centred systems are much better pi-donors to soft metals than sigma-donors to hard metals. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.

Application of 10343-06-3, An article , which mentions 10343-06-3, molecular formula is C14H20O10. The compound – 2,3,4,6-Tetra-o-acetyl-D-glucopyranose played an important role in people’s production and life.

Acacetin and resveratrol 3,5-di-O-beta-glucopyranoside were synthesized from naturally abundant naringin and piceid in 65% and 62% overall yield, respectively. The key steps were the regioselective deacetylation of the peracetates of the glycosylated forms with Candida antarctica lipase B (Novozym 435) and Burkholderia cepacia lipase (Amano PS-IM). Deacetylation occurred exclusively at the least hindered position of the aromatic moieties and all acetyl groups in the sugar side chain remained intact. This excellent selectivity enabled regiospecific transformation of the liberated phenolic hydroxy groups, resulting in efficient synthesis of the target molecules.
