Borjian Boroujeni, Mahmoud published the artcileA Novel and Green In Situ Strategy for the Synthesis of Metallophthalocyanines on Chitosan and Investigation Their Catalytic Activity in the CO2 Fixation, Computed Properties of 91-15-6, the main research area is green metallophthalocyanine chitosan catalyst cyclic carbonate.

Abstract: In this work, a novel and green strategy for the in situ synthesis of metallophthalocyanines on chitosan (MPcs@CS; M=Cu, Ni, Co) in deep eutectic solvents (DESs) at 120 °C has been reported. The chem. and structural properties of the MPcs@CS were determined by SEM (SEM), energy-dispersive X-ray(EDS), X-ray powder diffraction (XRD), Fourier transformation IR spectroscopy(FT-IR), thermogravimetric anal.(TGA) and flame at. absorption spectroscopies(FAAS). This new MPcs@CS is a highly efficient, active and reusable catalyst for the synthesis of cyclic carbonates from promoting the reaction of CO2 with epoxides under mild reaction conditions (at 80 °C and 1 atm CO2 pressure) with good to excellent yield of products. The order of catalytic activity is CuPc@CS, CoPc@CS and NiPc@CS from the conversion, temperature and time point of view, resp.

Darwish, Wael M. published the artcileTargeted photoimmunotherapy based on photosensitizer-antibody conjugates for multiple myeloma treatment, HPLC of Formula: 91-15-6, the main research area is multiple myeloma treatment photosensitizer antibody photoimmunotherapy; Antibody; Myeloma; Photoimmunotherapy; Phthalocyanine polymers; Radioimmunotherapy.

Despite the high in vitro efficacy of photodynamic therapeutics, lack of tumor targeting significantly reduces their in vivo efficacy and thus limits their clin. use. Photoimmunotherapy (PIT) is a new synthetic strategy to target and treat cancer by photodynamic therapy (PDT). In this study, we describe design and synthesis of a third-generation photosensitizer comprising a PEGylated-phthalocyanine star-polymer photosensitizer that covalently bound to a myeloma tumor-selective antibody (MAb) via the carbodiimide chem. The free photosensitizer demonstrated a min. dark toxicity when tested in mammalian myeloma cell line (SP2/OR); and a moderate phototoxicity after irradiation with non thermal laser red light as a result of light-induced production of cytotoxic singlet oxygen species. Covalent attachment of the photosensitizer (Pc) to the MAb resulted in a significantly enhanced phototoxicity. This is mainly ascribed to the fact that internalization enhances phototoxicity of Pc-MAb bioconjugates. The radioactivated photoimmuno-conjugates 131I(PcMAb) demonstrated the highest phototoxicity to myeloma cells. The suggested bioconjugates are promising candidates as multiple therapeutic models for in vivo treatment of myeloma.

Malik, Nadeem A. published the artcileTurbulent particle pair diffusion: Numerical simulations, Quality Control of 100-70-9, the main research area is turbulent particle pair diffusion coefficient Kolmogorov turbulence numerical simulation.

A theory for turbulent particle pair diffusion in the inertial subrange [Malik NA, PLoS ONE 13(10):e0202940 (2018)] is investigated numerically using a Lagrangian diffusion model, Kinematic Simulations [Kraichnan RH, Phys. Fluids 13:22 (1970); Malik NA, PLoS ONE 12(12):e0189917 (2017)]. All predictions of the theory are observed in flow fields with generalised energy spectra of the type, E(k) ∼ k-p. Most importantly, two non-Richardson regimes are observed: for short inertial subrange of size 102 the simulations yield quasi-local regimes for the pair diffusion coefficient, K(l)∼σl(1+p)/2; and for asymptotically infinite inertial subrange the simulations yield non-local regimes K(l)∼σlγ, with γ intermediate between the purely local scaling γnl = (1 + p)/2 and the purely non-local scaling γnl = 2. For intermittent turbulence spectra, E(k) ∼ k-1.72, the simulations yield K∼σl1.556, in agreement with the revised 1926 dataset K∼σl1.564 [Richardson LF, Proc.Roy.Soc.Lond.A 100:709 (1926); Malik NA, PLoS ONE 13(10):e0202940 (2018)]. These results lend support to the phys. picture proposed in the new theory that turbulent diffusion in the inertial subrange is governed by both local and non-local diffusion transport processes.

Mao, Qing published the artcileDesign, synthesis and biological evaluation of 2-(4-alkoxy-3-cyano)phenyl-6-oxo-1,6-dihydropyrimidine-5-carboxylic acid derivatives as novel xanthine oxidase inhibitors, Safety of 4-Hydroxyisophthalonitrile, the main research area is alkoxycyanophenyl oxodihydropyrimidine carboxylic acid preparation xanthine oxidase inhibitor SAR; acute toxicity docking hypouricemic alkoxycyanophenyl oxodihydropyrimidine carboxylic acid preparation; 1,6-Dihydropyrimidine-5-carboxylic acid; Biological evaluation; Synthesis; Xanthine oxidase inhibitor.

A series of 2-(4-alkoxy-3-cyano)phenyl-1,6-dihydropyrimidine-5-carboxylic acid derivatives I [R = O, NH; R1 = i-Pr, allyl, Bn, etc.; R2 = H, Me] was synthesized as novel xanthine oxidase (XO) inhibitors. These compounds exhibited remarkable in vitro XO inhibitory potency with IC50 values ranging from 0.0181 μM to 0.5677 μM. Specifically, compounds I [R = NH; R1 = (CH2)2CH(CH3)2, 2-methylallyl], with IC50 values of 0.0240 μM and 0.0181 μM, resp., emerged as the most potent XO inhibitors and their potencies were comparable to that of febuxostat. Structure-activity relationship anal. revealed that the Me group at 4-position of pyrimidine ring could damage the potency and the XO inhibitory potency was maintained when carbonyl group was changed to an imino group. Lineweaver-Burk plot anal. revealed that the representative compound I [R = NH; R1 = (CH2)2CH(CH3)2] acted as a mixed-type inhibitor. A potassium oxonate induced hyperuricemia model in rats was chosen to further confirm the hypouricemic effect of compound I [R = NH; R1 = (CH2)2CH(CH3)2] and the results showed that compound I [R = NH; R1 = (CH2)2CH(CH3)2] (5 mg/kg) was able to significantly lower the serum uric acid level. Furthermore, in acute oral toxicity study, no sign of toxicity was observed when the mice were administered with a single 2000 mg/kg oral dose of compound I [R = NH; R1 = (CH2)2CH(CH3)2]. These results suggested that compound I [R = NH; R1 = (CH2)2CH(CH3)2] was a potent and promising uric acid-lowing agent for the treatment of hyperuricemia.

Van Genderen, H. published the artcileToxicological properties of the herbicide dichlobenil, 2,6-dichlorobenzonitrile, in warm-blooded animals, SDS of cas: 3336-34-3, the publication is Mededelingen Rijksfaculteit Landbouwwetenschappen, Gent (1966), 31(3), 1026-31, database is CAplus.

After oral administration of 100 mg. dichlobenil/kg. body weight, rabbits converted approx. 23% into 2,6-dichloro-3-hydroxybenzonitrile (I) and 2% into the 4-hydroxy analog (II). Rats excreted, resp., 22% and 9% of I and II. In mice the i.p. LD50 for I and II was 83 mg./kg. and 50 mg./kg., resp. The oral toxicity for mice and rabbits was very much lower. The effects of I and II were studied on the respiration of bakers’ yeast, on the ATPase induction in isolated mitochondria, on the contraction of isolated rat diaphragm, and on single beating rat heart cells in tissue culture. It was concluded that I and II, like other chlorophenols, were uncoupling agents of oxidative phosphorylation with approx. the same potency as 2,4-dinitrophenol. Liver function tests with dichlobenil showed different results for rats and rabbits. The effect on the liver of the rat seemed to be reversible, but, at a critical dose level for the rabbit, it was irreversible. It was suggested that in the rat liver cells the conjugation of the phenols to glucuronides and sulfates could keep pace with their formation.

Cox, Oakley B. published the artcileA poised fragment library enables rapid synthetic expansion yielding the first reported inhibitors of PHIP(2), an atypical bromodomain, Category: nitriles-buliding-blocks, the publication is Chemical Science (2016), 7(3), 2322-2330, database is CAplus and MEDLINE.

Research into the chem. biol. of bromodomains has been driven by the development of acetyl-lysine mimetics. The ligands are typically anchored by binding to a highly conserved asparagine residue. Atypical bromodomains, for which the asparagine is mutated, have thus far proven elusive targets, including PHIP(2) whose parent protein, PHIP, has been linked to disease progression in diabetes and cancers. The PHIP(2) binding site contains a threonine in place of asparagine, and solution screening have yielded no convincing hits. We have overcome this hurdle by combining the sensitivity of X-ray crystallog., used as the primary fragment screen, with a strategy for rapid follow-up synthesis using a chem.-poised fragment library, which allows hits to be readily modified by parallel chem. both peripherally and in the core. Our approach yielded the first reported hit compounds of PHIP(2) with measurable IC₅₀ values by an AlphaScreen competition assay. The follow-up libraries of four poised fragment hits improved potency into the sub-mM range while showing good ligand efficiency and detailed structural data.

Larson, Peter published the artcileDesign and Synthesis of N1-Modified Imidazoquinoline Agonists for Selective Activation of Toll-like Receptors 7 and 8, Application In Synthesis of 5098-14-6, the publication is ACS Medicinal Chemistry Letters (2017), 8(11), 1148-1152, database is CAplus and MEDLINE.

A series of N1-modified imidazoquinolines were synthesized and screened for Toll-like receptors (TLR) 7 and 8 activities to identify recognition elements that confer high affinity binding and selectivity. These receptors are key targets in the development of immunomodulatory agents that signal the NF-κB mediated transcription of pro-inflammatory chemokines and cytokines. Results are presented showing both TLR7/8 activations are highly correlated to N1-substitution, with TLR8 selectivity achieved through inclusion of an ethyl-, propyl-, or butylamino group at this position. While the structure-activity relationship anal. indicates TLR7 activity is less sensitive to N1-modification, extension of the aminoalkyl chain length to pentyl and p-methylbenzyl elicited high affinity TLR7 binding. Cytokine profiles are also reported that show the pure TLR8 agonist [4-amino-2-butyl-1-(2-aminoethyl)-7-methoxycarbonyl-1H-imidazo[4,5-c]quinoline] (I) induces higher levels of IL-1β, IL-12, and IFNγ when compared with TLR7 selective or mixed TLR7/8 agonists. The results are consistent with previous work suggesting TLR8 agonists are Th1 polarizing and may help promote cell-mediated immunity.
