Berry, John F. published the artcileA molecular loop with interstitial channels in a chiral environment: exploration of the chemistry of Mo₂⁴⁺ species with chiral and non-chiral dicarboxylate anions, Category: catalysis-chemistry, the publication is Dalton Transactions (2003), 4297-4302, database is CAplus.

An enantiomerically pure chiral loop containing two units of cis-Mo₂(DAniF)₂²⁺ (DAniF = di-p-anisylformamidinate) was obtained by reacting cis-[Mo₂(DAniF)₂(NCMe)₄](BF₄)₂ with a chiral dicarboxylate easily prepared from p-, m-, and o-hydroquinone and Et (S)-lactate (H₂L1-H₂L3). The compound [cis-Mo₂(DAniF)₂]₂(L1)₂¡¤4CH₂Cl₂ (1) crystallizes in the noncentrosym. I222 space group with mols. stacking so as to form channels capable of hosting guest mols. such as CH₂Cl₂. These properties of 1, which was synthesized in high yield, makes it promising for applications in stereoselective catalysis. Similar reactions with H₂L2-3 and isomeric dicarboxylate linkers and some nonchiral ligands (HO₂CC(Me)₂O)₂-m-C₆H₄ and (HO₂CCH₂O)₂-o-C₆H₄ were studied. The nature of the products depends on the bite angle of the ligand.

Thakur, Punam published the artcileComplexation studies of Cm(III), Am(III), and Eu(III) with linear and cyclic carboxylates and polyaminocarboxylates, Application In Synthesis of 5411-14-3, the publication is Journal of Coordination Chemistry (2011), 64(18), 3214-3236, database is CAplus.

Solvent extraction and potentiometric titration methods were used to measure the stability constants of Cm(III), Am(III), and Eu(III) with both linear and cyclic carboxylates and polyaminocarboxylates in an ionic strength of 0.1 mol L^-1 (NaClO₄). Luminescence lifetime measurements of Cm(III) and Eu(III) were used to study the change in hydration upon complexation over a range of concentrations and pH values. Aromatic carboxylates, phthalate (1,2 benzene dicarboxylates, PHA), trimesate (1,3,5 benzene tricarboxylates, TSA), pyromellitate (1,2,4,5 tetracarboxylates, PMA), hemimellitate (1,2,3 benzene tricarboxylates, HMA), and trimellitate (1,2,4 benzene tricarboxylates, TMA) form only 1:1 complexes, while both 1:1 and 1:2 complexes were observed with PHA. Their complexation strength follows the order: PHA approx. TSA > TMA > PMA > HMA. Carboxylate ligands with adjacent carboxylate groups are bidentate and replace two H₂O mols. upon complexation, while TSA displaces 1.5 H₂O mols. of hydration upon complexation. Only 1:1 complexes were observed with the macrocyclic dicarboxylates 1,7-diaza-4,10,13-trioxacyclopentadecane-N,N’-diacetate (K21DA) and 1,10-diaza-4,7,13,16-tetraoxacyclooctadecane-N,N’-diacetate (K22DA); both 1:1 and 1:2 complexes were observed with methyleneiminodiacetate (MIDA), hydroxyethyleneiminodiacetate (HIDA), benzene-1,2-bis(oxyacetate) (BDODA), and ethylenediaminediacetate (EDDA), while three complexes (1:1, 1:2, and 1:3) were observed with pyridine 2,6 dicarboxylates (DPA) and chelidamate (CA). The complexes of M-MIDA are tridentate, while that of M-HIDA is tetradentate in both 1:1 and 1:2 complexes. The M-BDODA and M-EDDA complexes are tetradentate in the 1:1 and bidentate in the 1:2 complexes. The complexes of M-K22DA are octadentate with one H₂O mol. of hydration, while that of K21DA is heptadentate with two H₂O mols. of hydration. Simple polyaminocarboxylate 1,2 diaminopropanetetraacetate (PDTA) and ethylenediamine N,N’-diacetic-N,N’-dipropionate (ENDADP) like ethylenediaminetetraacetate (EDTA) form only 1 : 1 complexes and their complexes are hexadentate. Polyaminocarboxylates with addnl. functional groups in the ligand backbone, e.g., ethylenebis(oxyethylenenitrilo)tetraacetate (EGTA), and 1,6 diaminohexanetetraacetate (HDTA) or with addnl. number of groups in the carboxylate arms diethylenetriamine pentaacetato-monoamide (DTPA-MA), diethylenetriamine pentaacetato-bis-methoxyethylamide (DTPA-BMEA), and diethylenetriamine pentaacetato-bis glucosaamide (DTPA-BGAM) are octadentate with one H₂O mol. of hydration, except N-Me MS-325 which is heptadentate with two H₂O mols. of hydration and HDTA which is probably dimeric with three H₂O mols. of hydration. Macrocyclic tetraaminocarboxylate, 1,4,7,10-tetraazacyclododecanetetraacetate (DOTA) forms only 1:1 complex which is octadentate with one H₂O mol. of hydration. The functionalization of these carboxylates and polycarboxylates affect the complexation ability toward metal cations. The results, in conjunction with previous results on the Eu(III) complexes, provide insight into the relation between ligand steric requirement and the hydration state of the Cm(III) and Eu(III) complexes in solution The data are discussed in terms of ionic radii of the metal cations, cavity size, basicity, and ligand steric effects upon complexation.

Lis, Stefan published the artcileLuminescence study of europium(III) complexes with several dicarboxylic acids in aqueous solution, SDS of cas: 5411-14-3, the publication is Journal of Alloys and Compounds (1995), 225(1-2), 257-60, database is CAplus.

Luminescence lifetimes of Eu(III) in complexes with dicarboxylate ligands and N, O or S donors have been measured in H₂O and D₂O solutions of varying pH and europium-ligand ratio. The ligands were iminodiacetate (IDA), diglycolate (DGA), thiodiglycolate (TDA), dipicolinate (DPA), benzene-1,2-bis(oxyacetate) (BDODA), ethylenediaminediacetate (EDDA) and ethylene-1,2-dithiodiacetate (EDTDA). The lifetimes have been used to measure the number of water mols. coordinated to the Eu(III) ion in each complex. The results show that in the 1:1 and 1:2 complexes the ligands: IDA, DGA and DPA are tridentate whereas the TDA complexes are bidentate. BDODA and EDDA form tetradentate 1:1 and bidentate 1:2 complexes, while EDTDA is bidentate in both the 1:1 and 1:2 complexes. These results indicate that the nitrogen and oxygen donors are bonded to lanthanide ions in the DGA, IDA, DPA and EDDA complexes, whereas the sulfur donors are not bonded in the TDA and EDTDA complexes.

The Na[Ln(C₁₀H₈O₆)₂(H₂O)₂]¡¤2H₂O (Ln = Yb(III), Lu(III)) monocrystals were obtained and the crystal structure was solved. The Yb(III) complex forms a structure with the space group P2₁/c and a 15.528(1), b 21.098(1), c 7.766(1) ?, and ¦Â 92.58(2)¡ã. Optical properties of this complex were studied using the methods of absorption (293 K, 4 K), luminescence (77 K) and IR spectroscopy. The ligand-field splitting in the relevant states can be determined from low-temperature high-resolution absorption and luminescence. The split of ²F_5/2 and ²F_7/2 was determined as 540 and 592 cm^-1, resp. The f-f luminescence was not induced by exciting into the ¹¦Ð-¹¦Ð^* absorption band of the ligand but only by exciting into Yb(III) level with a very short ²F_5/2 level decay time equal to 0.32 and 0.69 ¦Ìs at 293 and 77 K, resp.

Chen, Wei published the artcileSnapshotting the Excited-State Planarization of Chemically Locked N,N’-Disubstituted Dihydrodibenzo[a,c]phenazines, Safety of 2,2-(1,2-Phenylenebis(oxy))diacetic acid, the publication is Journal of the American Chemical Society (2017), 139(4), 1636-1644, database is CAplus and MEDLINE.

For deeper understanding of the coupling of electronic processes with conformational motions, we exploit a tailored strategy to harness the excited-state planarization of N,N’-disubstituted dihydrodibenzo[a,c]phenazines by halting the structural evolution via a macrocyclization process. In this new approach, 9,14-diphenyl-9,14-dihydrodibenzo[a,c]phenazine (DPAC) is used as a prototype, in which the para sites of 9,14-diphenyl are systematically enclosed by a dialkoxybenzene-alkyl-ester or -ether linkage with different chain lengths, imposing various degrees of constraint to impede the structural deformation. Accordingly, a series of DPAC-n (n = 1-8) derivatives were synthesized, in which n correlates with the alkyl length, such that the strength of the spatial constraint decreases as n increases. The structures of DPAC-1, DPAC-3, DPAC-4, and DPAC-8 were identified by the X-ray crystal anal. As a result, despite nearly identical absorption spectra (onset ?400 nm) for DPAC-1-8, drastic chain-length dependent emission is observed, spanning from blue (n = 1, 2, ?400 nm) and blue-green (n = 3-5, 500-550 nm) to green-orange (n = 6) and red (n = 7, 8, ?610 nm) in various regular solvents. Comprehensive spectroscopic and dynamic studies, together with a computational approach, rationalized the associated excited-state structure responding to emission origin. Severing the linkage for DPAC-5 via lipase treatment releases the structural freedom and hence results in drastic changes of emission from blue-green (490 nm) to red (625 nm), showing the brightening prospect of these chem. locked DPAC-n in both fundamental studies and applications.

{[Ln₂(PDOA)₃(H₂O)₆]?2H₂O}_n (Ln = Gd, 1; Ln = Ce, 2; H₂PDOA = ¦Ï-phenylenedioxydiacetic acid) has been synthesized and characterized by chem. analyses, IR spectroscopy, and thermal analyses. Single-crystal X-ray structure analyses revealed that both 1 and 2 are polymeric and built up of a ladder-like arrangement of Ln(III) ions linked by short syn-anti carboxylate bridges and long bridges (legs of the ladder) formed by a second crystallog. independent PDOA. Ln(III) in both 1 and 2 is nine-coordinate with an O₉ donor set formed by one chelating/bridging and one bridging PDOA, and an addnl. three waters. In the asym. unit, there is one crystallog. independent water of crystallization, which is involved in a rich system of hydrogen bonds of the O-H¡¤¡¤¡¤O type. The identities of the bulk and single crystal phases were corroborated by powder X-ray diffraction. Variable temperature (2-300 K) magnetic studies indicate the presence of only weak antiferromagnetic interactions between pairs of paramagnetic Ln(III) ions with J/hc = -0.004 and -0.13 cm^-1, for 1 and 2.

Stolarova, Monika published the artcileTwo novel coordination polymers in the family of lanthanide complexes with o-phenylenedioxydiacetato as ligand, Synthetic Route of 5411-14-3, the publication is Polyhedron (2015), 149-155, database is CAplus.

Two novel coordination polymers [Ce(PDOA)(NO₃)(H₂O)₂]_n (1) and {[Ce(PDOA)(NO₃)(H₂O)₃]¡¤H₂O}_n (2) (PDOA = o-phenylenedioxydiacetato) have been prepared using hydrothermal conditions and have been structurally characterized. In both crystal structures 1 and 2 the Ce(III) atoms are decacoordinated by oxygen atoms from PDOA ligands with chelating and bridging functions, chelating nitrato ligands and aqua ligands. While in 1 the PDOA ligand presents a hexadentate coordination mode, in 2 it is coordinated in a pentadentate manner; this difference leads to different types of one-dimensional structural motifs: in 2 there are zig-zag chains of the -Ce-O-C-O-Ce- type with syn-anti carboxylate bridges and in 1 these chains are addnl. interlinked by further syn-anti carboxylate bridges leading to a strip- or ribbon-like arrangement formed of {Ce₃} fused triangles. The endothermic dehydration of 1 within the temperature range 69-199 ¡ãC is at least a two-step process as suggested by TG and DTA methods. A variable temperature (2-300 K) magnetic study reveals Curie-Weiss behavior for 1 with ¦È = -35.5 K observed above 50 K. The origin of the observed behavior is discussed.

Benzene-1,2-dioxyacetic acid (bdoaH₂) reacts with Mn(CH₃CO₂)₂¡¤4H₂O in an EtOH-H₂O mixture to give the Mn(II) complex [Mn(bdoa)(H₂O)₃]. The x-ray crystal structure of the complex shows the metal to be pseudo seven-coordinate. The quadridentate bdoa^2- dicarboxylate ligand forms an essentially planar girdle around the metal, being strongly bonded transoid by a carboxylate O atom from each of the two carboxylate moieties (mean Mn-O 2.199 ?) and also weakly chelated by the two internal ether O O atoms (mean Mn-O 2.413 ?). The coordination sphere about the Mn is completed by three H₂O mols. (mean Mn-O 2.146 ?) lying in a meridional plane orthogonal to that of the bdoa^2- ligand. Magnetic, conductivity and voltammetry data for the complex are given, and its use as a catalyst for the disproportionation of H₂O₂ is described.

Elumalai, Nagarajan published the artcileNanomolar Inhibitors of the Transcription Factor STAT5b with High Selectivity over STAT5a, Formula: C10H10O6, the publication is Angewandte Chemie, International Edition (2015), 54(16), 4758-4763, database is CAplus and MEDLINE.

Src homol. 2 (SH2) domains play a central role in signal transduction. Although many SH2 domains have been validated as drug targets, their structural similarity makes development of specific inhibitors difficult. The cancer-relevant transcription factors STAT5a and STAT5b are particularly challenging small-mol. targets because their SH2 domains are 93% identical on the amino acid level. Here the authors present the natural product-inspired development of the low-nanomolar inhibitor I, as the first small mol. which inhibits the STAT5b SH2 domain (K_i=44 nM) with more than 50-fold selectivity over STAT5a. The binding site of the core moiety of I was validated by functional anal. of point mutants. A prodrug of I was shown to inhibit STAT5b with high selectivity over STAT5a in tumor cells. I provides the first demonstration that naturally occurring SH2 domains with more than 90% sequence identity can be selectively targeted with small organic mols.
