We report the design and synthesis of push-pull benzothiadiazoles (BTDs) of type D1-pi-A-pi-D2 and D1-pi-A-D2. These BTDs show strong charge transfer interaction. BTD 3 shows reversible mechanochromism with color contrast between yellow (crystalline state) and orange (amorphous state). Photophysical and computational studies reveal that the planar orientation of the pyridyl and BTD unit in 2 results in no change in solid state emission whereas non-planar orientation of the dipyridylamine and BTD unit in 3 results in efficient mechanochromism.

Product Details of 499-40-1, Chemical engineers work across a number of sectors, processes differ within each of these areas, are directly involved in the design, development, creation and manufacturing process of chemical products and materials. An article , which mentions 499-40-1, molecular formula is C12H22O11. The compound – (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal played an important role in people’s production and life.

The CoRu2(dpa)4Cl2 (1) (dpa: 2,2?-dipyridylamide) is synthesized by the reaction of Ru2(OAc)4Cl and Co3(dpa)4Cl2. By mixing 1 with NH3, Co2+ can be removed and result in the formation of unique binuclear complex 4,0-Ru2(dpa)4Cl (2) featuring one coordination pocket supported by free pyridine groups. Hence, this complex can act as an outstanding precursor for the formation of heterotrimetallic chains with MRu2 cores. A series of M-Ru25+ complexes (M = Co2+ (3), Ag+ (4), Mn2+ (5), Fe2+ (6), Zn2+ (7), Cd2+ (8), Pd2+ (9), Rh2+ (10), and Ir2+ (11)) were prepared and isolated, representing the most complete series of heterotrimetallic chains to date. All these metal string complexes are in a linear trimetallic framework helically wrapped by four dpa- ligands, characterized by X-ray diffraction measurements. The bending of the trinuclear metal cores in RhRu2 (10) and IrRu2 (11) (?Ru-Ru-Rh: 167.58 and ?Ru-Ru-Ir: 167.61) indicates that a heterometallic metal-metal bonds (Ru-Rh; Ru-Ir) are generated. The studies from DFT calculation of 10 and 11 coincide with the experimental results. Furthermore, the M?Ru25+ distances are regulated by the factors including the bonding force of M-pyridyl and the static repulsion between M and Ru25+ unit. Interestingly, the trend for these distances is in line with that observed in trans-M(py)4Cl2 complexes.

The leishmaniases are diseases that affect millions of people across the world, in particular visceral leishmaniasis (VL) which is fatal unless treated. Current standard of care for VL suffers from multiple issues and there is a limited pipeline of new candidate drugs. As such, there is a clear unmet medical need to identify new treatments. This paper describes the optimization of a phenotypic hit against Leishmania donovani, the major causative organism of VL. The key challenges were to balance solubility and metabolic stability while maintaining potency. Herein, strategies to address these shortcomings and enhance efficacy are discussed, culminating in the discovery of preclinical development candidate GSK3186899/DDD853651 (1) for VL.

category: Tetrahydropyrans. In homogeneous catalysis, catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. Introducing a new discovery about 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal

A new compound, [Cu(dpyam)(OH)]2(ClO4)2 (dpyam = di-2-pyridylamine) is studied in detail and characterised by magnetic susceptibility and heat capacity measurements. This unique compound exhibits two phase transitions at 192 and 116 K. To obtain more insight into the origin of this transition, X-ray crystal structures at 3 different temperatures, below (1A, 110 K), between (1B, 150 K) and above (1C, 200 K) the transitions are measured. The structure consists of a dinuclear CuII unit with two bridging hydroxo groups and with two ligands bound to each copper atom via N, while the axial sites are occupied by oxygen atoms of bridging perchlorate anions, providing a distorted tetragonal environment with a Cu-Cu distance which varies from 2.9328(6) to 2.9633(6) A, and a Cu-O-Cu angle which varies from 99.00(9) to 100.53(9). In all three structures, the Cu2O2L2 unit does not change significantly. The only changes involve the position of the perchlorate anions and their H bonds with the bridging OH groups. These anions have slightly different positions at different temperatures and appear to be the major origin of the crystallographic phase-transitions. Fitting the magnetic susceptibility measurements revealed a singlet-triplet separation (J) of -37.2 cm-1 (antiferromagnetic), in the temperature ranges 275-190 K and 115-50 K. In the range 190-115 K a best fit, albeit inaccurate, of 29.3 cm-1 for J (ferromagnetic) is found. A small magnetic hysteresis of 0.5 K has been observed in the phase transition at 116 K. The heat capacity measurements have confirmed the transitions and the excess entropy (DeltaS) and enthalpy (DeltaH) have been calculated as 4.9 and 2.0 J K-1 mol-1 for DeltaS (for 192.3 K and 116.4 K, respectively), and 0.96 and 0.25 kJ mol-1 for DeltaH (for 192.3 K and 116.4 K, respectively).
