The reaction of 6-phenyl-2-thioxo-2,3-dihydropyrimidin-4(5H)-one with acetyl chloride in acetic anhydride in the presence of sodium acetate afforded 5-acetyl-6-phenyl-2-thioxo-2,3-dihydropyrimidin-4(5H)-one which was reacted with bromine, hydrazine hydrate, phenylhydrazine, cyanothioacetamide, aldehydes ArCHO (Ar = Ph, 4-chlorophenyl, 4-methoxyphenyl) and (malononitrile/sulfur) to give 2-thioxo-2,3-dihydropyrimidine derivatives, e.g., I. In the present investigation 6-phenyl-2-thioxo-2,3-dihydropyrimidin-4(5H)-one was reacted with chloroacetyl chloride to yield the corresponding compound 5-(2-chloroacetyl)-6-phenyl-2-thioxo-2,3-dihydropyrimidin-4(5H)-one. Compound 6-phenyl-2-thioxo-2,3-dihydropyrimidin-4(5H)-one was reacted with some electrophilic reagents such as benzylidene-cyanothioacetamide derivatives, 2-cyano-2-cyclopentylethanethioamide, 2-cyano-2-cyclohexyl-ethanethioamide and aromatic diazonium salts Ar¹N₂⁺Cl^– to give compounds, e.g., II (X = CH₂, CH₂CH₂). The newly synthesized heterocycles were characterized on the basis of their chem. properties and spectral data.

Crook, James W. published the artcileBehavior of halogen-containing phosphates and phosphonates in urethane foam, COA of Formula: C5H10Cl3O3P, the publication is Journal of Cellular Plastics (1969), 5(2), 119-22, database is CAplus.

(ClCH2CH2CH2O)3P:O (I) was as effective as (ClCH2CH2O)3P:O (II) as a flame-retardant in urethane foam, but had a lower chem. reactivity than II and thus caused less scorch. Foam was prepared from oxypropylated glycerol 100, II 10, (C7H15CO2)2Sn 0.5, triethylenediamine 0.1, H2O 3.5, siloxane-oxyalkylene copolymer 1.0, and tolylene diisocyanate 45.4 parts. Prior to aging, 90% phosphate could be removed by extraction with boiling C6H6. After aging 48 hrs. at 140°, only 1.7% of the original P content could be extracted by boiling C6H6. Extraction with boiling 1:1 aqueous EtOH removed 78% of the P, and the extract was strongly acidic. The strongly acidic products formed during foam making were responsible for scorch. Heating 220 g. II at 150° for 105 hrs. under N gave 3 g. ClCH2CH2Cl (III). When 57.1 g. II and 15.9 g. N,N’-diphenylurea (IV) were heated at 150° under N for 48 hrs., the products isolated were III 17.6, 1,3-diphenyl-2-imidazolidone (m. 211-13°) 3.6, and N,N’-diphenylpiperazine (m. 165.5-7.6°) 5.4 g. The mechanism of the reaction rates of (BrCH2CH2CH2O)3P:O, I, Cl3CP(O)(OEt)2 (Kosolapoff, 1947), BrCH2CH2CH2P(O)(OEt)2 (prepared according to Eberhard, 1965), (ClCH2CHClCH2O)3P:O, and (BrCH2CHBrCH2O)3P:O with IV were compared. I was the least reactive. I showed greater hydrolytic stability than II and was less reactive toward bases. Foams were prepared using Daltocel SF polyester containing I or II and the fire-retardancy was similar according to ASTM D 1692-59T.

Peyrovedin, Hamed published the artcileA global model for the estimation of speeds of sound in deep eutectic solvents, Related Products of chlorides-buliding-blocks, the publication is Molecules (2020), 25(7), 1626, database is CAplus and MEDLINE.

Deep eutectic solvents (DESs) are newly introduced green solvents that have attracted much attention regarding fundamentals and applications. Of the problems along the way of replacing a common solvent by a DES, is the lack of information on the thermophys. properties of DESs. This is even more accentuated by considering the dramatically growing number of DESs, being made by the combination of vast numbers of the constituting substances, and at their various molar ratios. The speed of sound is among the properties that can be used to estimate other important thermodn. properties. In this work, a global and accurate model is proposed and used to estimate the speed of sound in 39 different DESs. This is the first general speed of sound model for DESs. The model does not require any thermodn. properties other than the critical properties of the DESs, which are themselves calculated by group contribution methods, and in doing so, make the proposed method entirely independent of any exptl. data as input. The results indicated that the average absolute relative deviation percentages (AARD%) of this model for 420 exptl. data is only 5.4%. Accordingly, based on the achieved results, the proposed model can be used to predict the speeds of sound of DESs.

Mekala, Shekar published the artcileA Scalable, Nonenzymatic Synthesis of Highly Stereopure Difunctional C₄ Secondary Methyl Linchpin Synthons, Synthetic Route of 21286-54-4, the publication is Journal of Organic Chemistry (2015), 80(3), 1610-1617, database is CAplus and MEDLINE.

In response to the continuing widespread use of heterodifunctional C₄ secondary Me building blocks in asym. synthesis, we have developed a mole-scale, two-step synthesis of a 1:1 mixture of the diastereomers of 3-bromo-2-methyl-1-Pr camphorsulfonate (casylate). One isomer I has been crystallized to >99:1 dr in âˆ?5% yield. Equilibration of the mother liquor (enriched in the other isomer) to a 1:1 mixture and recrystallization significantly raises the overall yield of I. Applications of I include chemoselective Grignard coupling, enabling the very short synthesis of highly stereopure long-chain natural products containing remote, methyl-bearing stereogenic centers [e.g., (R)-tuberculostearic acid (II)], with complete control of configuration. Also, Ag-mediated, completely chemoselective Br displacement from I leads to a range of >99:1 er difunctional synthons. Both applications incorporate concurrent recovery of CasO. The enantiomer of I can be made from com. (1R)-10-CasOH.

Kiran, Sonia published the artcileAlkaline phosphatase-triggered assembly of etoposide enhances its anticancer effect, Recommanded Product: 2-Chlorotrityl chloride, the publication is Chemical Communications (Cambridge, United Kingdom) (2018), 54(15), 1853-1856, database is CAplus and MEDLINE.

Etoposide is a cancer-targeting drug but an overdose of etoposide leads to immunosuppression in patients. Therefore, the development of a new strategy to enhance its anticancer effect, while in the meantime alleviating its adverse effects, is important but challenging. In this work, with the assistance of a hydrogelator precursor Nap-Phe-Phe-Tyr(H₂PO₃)-OH (1P), etoposide phosphate (EP) was subjected to alk. phosphatase (ALP)-triggered assembly, which obviously enhanced its anticancer efficacy in vitro and in vivo. In vitro tests indicated that the assembly of EP with 1P resulted in a slow release of etoposide and long-term inhibitory effects on HeLa cells. In vivo experiments indicated that, compared with those of EP-treated mice, the tumor growth of EP + 1P-treated mice was further inhibited while their body weight loss was alleviated. We envision that our hydrogelator-assisted assembly strategy could be applied to enhance the therapeutic effects of more drugs, while in the meantime alleviating their adverse effects in the future.

Creighton, John A. published the artcileVibrational spectra of some trimethylsulfoxonium salts, -h9 and -d9, COA of Formula: C3H9ClOS, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (1969), 25(7), 1314-18, database is CAplus.

The ir (3650-40 cm.-1) and Raman spectra of (CD3)3,SOI as a solid, Raman data for Me3SOCl and Me3SOI as salts and for the former in aqueous solution have been obtained, and the ir spectra recorded to 50 cm.-1 For the cations there are 36 fundamentals which for C3v geometry divide by Γ = 8 a1 + 4a2 + 12e. The previous interpretation of Me3SOI (C., et al., 1967) is largely confirmed by the new results. The frequencies 1339 and 1318 cm.-1 are now taken as a1 and e, resp., rather than as the reverse of this since, for the corresponding Raman lines of the chloride in solution, that at 1348 cm.-1 appears polarized while that at 1313 cm.-1 is depolarized. The ν (C-S) modes are observed in the Raman spectra. A feature of particular note in the Raman spectrum of solid Me3SOI is the prominent line at 1371 cm.-1 which appears to have its counterpart for (CD3)3SOI at 990 cm.-1 The corresponding ir bands are very weak. Comparison is made with the fundamental frequencies for the isoelectronic mol. (CH3)3PO, with small changes in the assignment.

Buendia, Julien published the artcileThe Multiple Facets of Iodine(III) Compounds in an Unprecedented Catalytic Auto-amination for Chiral Amine Synthesis, Application In Synthesis of 866-23-9, the publication is Angewandte Chemie, International Edition (2016), 55(26), 7530-7533, database is CAplus and MEDLINE.

Iodine(III) reagents are used in catalytic one-pot reactions, first as both oxidants and substrates, then as cross-coupling partners, to afford chiral polyfunctionalized amines. The strategy relies on an initial catalytic auto C(sp³)-H amination of the iodine(III) oxidant, which delivers an amine-derived iodine(I) product that is subsequently used in palladium-catalyzed cross-couplings to afford a variety of useful building blocks with high yields and excellent stereoselectivities. This study demonstrates the concept of self-amination of the hypervalent iodine reagents, which increases the value of the aryl moiety.

De Pascale, G. published the artcileValidation for high-throughput screening of a VanRS-based reporter gene assay for bacterial cell wall inhibitors, Application of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Journal of Applied Microbiology (2007), 103(1), 133-140, database is CAplus and MEDLINE.

The present study was undertaken to validate, for antibiotic discovery, a reporter gene assay based on a Bacillus subtilis strain expressing the Enterococcus faecium vanRS genes and a vanH-lacZ fusion, which produced β-galactosidase activity in the presence of cell wall inhibitors (CWI) and lysozyme. The reporter assay was miniaturized, automated and validated with antibiotics and tested against portions of chem. and microbial extract libraries. The assay is simple, fast and reproducible and can detect all CWI, sometimes at concentrations lower than those necessary to inhibit bacterial growth. However, some membrane-interfering compounds also generate comparable signals. While most CWI elicit a signal that is transcription-dependent and abolished in an osmoprotective medium, transcription is not required for β-galactosidase activity brought about by the membrane-interfering compounds At least two distinct mechanisms appear to lead to enzymic activity in the reporter strain. Effective counterscreens can be designed to discard the undesired classes of compounds Extensive validation is required before introducing a reporter assay in high-throughput screening. However, the ease of operation and manipulation makes the reporter assays powerful tools for antibiotic discovery.
