A compendium of phase change enthalpies published in 2010 is updated to include the period 1880-2015. Phase change enthalpies including fusion, vaporization, and sublimation enthalpies are included for organic, organometallic, and a few inorganic compounds. Part 1 of this compendium includes organic compounds from C1-C10. Part 2 of this compendium, to be published separately, will include organic and organometallic compounds from C11 to C192. Sufficient data are presently available to permit thermodynamic cycles to be constructed as an independent means of evaluating the reliability of the data. Temperature adjustments of phase change enthalpies from the temperature of measurement to the standard reference temperature, T = 298.15 K, and a protocol for doing so are briefly discussed.

In continuation of our previous work on the design and synthesis of topoisomerase II (Topo II) inhibitors and DNA intercalators, a new series of quinoxaline derivatives were designed and synthesized. The synthesized compounds were evaluated for their cytotoxic activities against a panel of three cancer cell lines (Hep G-2, Hep-2, and Caco-2). Compounds 18b, 19b, 23, 25b, and 26 showed strong potencies against all tested cell lines with IC50 values ranging from 0.26 ± 0.1 to 2.91 ± 0.1 muM, comparable with those of doxorubicin (IC50 values ranging from 0.65 ± 0.1 to 0.81 ± 0.1 muM). The most active compounds were further evaluated for their Topo II inhibitory activities and DNA intercalating affinities. Compounds 19b and 19c exhibited high activities against Topo II (IC50 = 0.97 ± 0.1 and 1.10 ± 0.1 muM, respectively) and bound the DNA at concentrations of 43.51 ± 2.0 and 49.11 ± 1.8 muM, respectively, whereas compound 28b exhibited a significant affinity to bind the DNA with an IC50 value of 37.06 ± 1.8 muM. Moreover, apoptosis and cell-cycle tests of the most promising compound 19b were carried out. It was found that 19b can significantly induce apoptosis in Hep G-2 cells. It has revealed cell-cycle arrest at the G2/M phase. Moreover, compound 19b downregulated the Bcl-2 levels, indicating its potential to enhance apoptosis. Furthermore, molecular docking studies were carried out against the DNA?Topo II complex to examine the binding patterns of the synthesized compounds.

Background: 1, 3, 4-thiadiazoles, 1, 3, 4-thiadiazines and thienopyrimidines have newly attracted attention due to their forceful pharmacological activities. They showed antimicrobial, antiviral, analgesic and anti-inflammatory properties. Objective: The aim of this research is to synthesize new thiadiazolothienopyrimidines (2-10), thienopyrimidothiadiazines (11-15), quinoxaline-thienopyrimidinones (16) and thienopyrimido- thiadiazinoquinoxalinones (17) via effectual high yield procedure for assessing their antimicrobial activity. Method: A series of new 1, 3, 4-thiadiazolothienopyrimidines, thienopyrimidothiadiazines and thienopyrimidothiadiazinoquinoxalinones was prepared from 6-acetyl-3-amino-5-methyl-2-thioxo-2, 3-dihydrothieno [2, 3-d] pyrimidin-4(1H)-one (1) as the beginning material. Results: The 1, 3, 4-thiadiazoles, 1, 3, 4-thiadiazines derivatives (1-17) were synthesized in adequate to good yields (60-85%) in a stepwise effectual procedure under condition. The chemical structures of these new compounds were confirmed via many spectroscopic techniques as UV, IR, NMR, mass spectra and elemental analysis. In vitro, antimicrobial was evaluated for the synthesized compounds using minimal inhibitory concentration of these compounds against bacteria and fungi. Conclusion: The 1, 3, 4-thiadiazole and 1, 3, 4-thiadiazine derivatives (15-17) exhibited higher antimicrobial activity (Gram-positive, Gram-negative bacteria and fungi) compared with the standard antibiotic drugs; Levofloxacin (Tavanic) and Nystatin.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C8H4Cl2N2, you can also check out more blogs about2213-63-0

In this study, three-component reaction of some primary and secondary amines with carbon disulfide in the presence of electron-deficient derivatives of chloropyridine or chlorobenzene in the CH3CN as a solvent is reported. The reaction of primary amines with carbon disulfide and electron-deficient compounds of chloropyridine or chlorobenzene after 6-8 h afforded the three-component addition product. The reaction of secondary amines with carbon disulfide and electron-deficient compounds of chloropyridine or chlorobenzene after 3-4 h afforded the two-component addition product. The product(s) of reactions were purified by recrystallization or column chromatography and their structures were identified by spectroscopy techniques such as 1H-NMR, 13C-NMR, IR, UV and elemental analysis. The reactions were carried out under mild conditions and without using a catalyst.

A series of novel hybrid molecules were designed rationally by connecting an indole moiety with a quinoxaline ring through a linker as potential inhibitors of PDE4. Their design was validated initially in silico by performing docking studies using a representative molecule. Subsequent synthesis of a focused library of related hybrid molecules was accomplished using Pd/C[sbnd]Cu mediated coupling-cyclization as a key step. Some of the synthesized compounds showed PDE4 inhibition in vitro and one of them appeared to be promising.

Soluble guanylate cyclase (sGC) is a haem containing enzyme that regulates cardiovascular homeostasis and multiple mechanisms in the central and peripheral nervous system. Commonly used inhibitors of sGC activity act through oxidation of the haem moiety, however they also bind haemoglobin and this limits their bioavailability for in vivo studies. We have discovered a new class of small molecule inhibitors of sGC and have characterised a compound designated D12 (compound 10) which binds to the catalytic domain of the enzyme with a KD of 11 muM in a SPR assay.

Resorcin[4]arene-based molecular baskets, with four free or methylene-bridged HO groups, and water-soluble container molecules bearing poly(ethylene glycol) chains of different lengths on the lower rim and cap have been synthesized. These cavitands, topped with p-xylylene bridges, feature well-defined cavities capable of encapsulating heteroalicyclic guests. Association constants (Ka) were determined by 1H NMR spectroscopy for the organic-soluble molecular baskets in CDCl3 and for the water-soluble container molecules in D2O/CD3CN (2:1). Opposite guest selectivities were observed in the two environments. Upon complexation, the water-soluble hosts show changes in their 1H NMR spectra. In the absence of guests, the p-xylylene bridge rotates rapidly on the 1H NMR timescale, revealing a time-averaged achiral C2v structure, whereas this rotation is hindered by guest inclusion, resulting in spectra showing a racemic C2-symmetric host, indicative of planar chirality.

In this account, the design, synthesis, and application of P-chirogenic phosphine ligands that have been mainly carried out in our laboratory over the last three decades are described. Various enantiopure P-chirogenic phosphine ligands have been efficiently prepared by using phosphine boranes as intermediates. Conformationally rigid and electron-rich P-chirogenic phosphine ligands possessing C2 symmetry as well as a bulky alkyl group and a small group at the phosphorus atoms exhibit excellent enantioselectivities and catalytic efficiency in a variety of transition-metal-catalyzed asymmetric reactions. Enantiopure 2,3-bis(tert-butylmethylphosphino)quinoxaline (QuinoxP*) is an air-stable crystalline solid that shows superior enantioinduction ability in catalytic asymmetric syntheses. Mechanistic studies of Rh-catalyzed asymmetric hydrogenation using structurally simple P-chirogenic phosphine ligands, such as tBu-BisP*, are briefly described. (Figure presented.).
