Cellular AND Gates: Synergistic Recognition to Boost Selective Uptake of Polymeric Nanoassemblies

Fernandez, Ann,Gao, Jingjing,Thayumanavan, S.,Wu, Peidong,Zhuang, Jiaming

, p. 10456 - 10460 (2020)

The development of nanoparticle-based biomedical applications has been hampered due to undesired off-target effects. Herein, we outline a cellular AND gate to enhance uptake selectivity, in which a nanoassembly–cell interaction is turned on, only in the concurrent presence of two different protein functions, an enzymatic reaction (alkaline phosphatase, ALP) and a ligand–protein (carbonic anhydrase IX, CA IX) binding event. Selective uptake of nanoassemblies was observed in cells that overexpress both of these proteins (unicellular AND gate). Interestingly, selective uptake can also be achieved in CA IX overexpressed cells, when cocultured with ALP overexpressed cells, where the nanoassembly presumably acts as a mediator for cell–cell communication (bicellular AND gate). This logic-gated cellular uptake could find use in applications such as tumor imaging or theranostics.

Kinetics and Mechanism of Oxidation of L-Threonine in Acid Media by Sodium N-Chloro-p-toluenesulfonamide

Mahadevappa, D. S.,Rangappa, K. S.,Gowda, N. M. M.,Gowda, B. Thimme

, p. 3651 - 3658 (1981)

Kinetics of oxidation of L-threonine in the presence of HCl, HClO4, and H2SO4 by chloramine-T (CAT) has been investigated at 35 deg C.The reactions follow identical kinetics in all acids, being first order in CAT, fractional order in substrate and Cl- ion, and of an inverse fractional order in +>.Variation of ionic strength and addition of the reaction product, p-toluenesulfonamide, or the ions SO42- and ClO4- had no effect on the rate.Decrease of dielectric constant of the medium by adding methanol decreased the rate.The solvent isotope effect was studied by using heavy water.The reactions were studied at different temperatures, and activation parameters have been computed.Mechanisms proposed and the derived rate laws are consistent with the observed kinetics.The rate constants predicted by the derived rate laws, as the concentrations of H+ ion, substrate, and Cl- ion change, are in excellent agreement with the observed rate constants, thus further justifying these rate laws and hence the proposed mechanistic schemes.

Synthesis of 8-Alkoxy-5 H-isochromeno[3,4- c]isoquinolines and 1-Alkoxy-4-arylisoquinolin-3-ols through Rh(III)-Catalyzed C-H Functionalization of Benzimidates with 4-Diazoisochroman-3-imines and 4-Diazoisoquinolin-3-ones

Li, Zhenmin,Lu, Ping,Wang, Yanguang,Xie, Jianwei

, p. 5525 - 5535 (2020)

Rh(III)-catalyzed C-H activation/annulation of benzimidates with 4-diazoisochroman-3-imines furnished 8-alkoxy-5H-isochromeno[3,4-c]isoquinolines in moderate to excellent yields with a broad range of substrate scope. The reaction was carried out under mild reaction conditions and could be scaled up with practical usage. Similar reaction between benzimidates and 4-diazoisoquinolin-3-ones provided 1-alkoxy-4-arylisoquinolin-3-ols in excellent yields. Moreover, the synthesized products could be conveniently transformed to the corresponding heterocycles with a 1,8-naphthyridinone or isochromenopyridinone core, which are privileged structures in medicinal chemistry.

Structural, vibrational spectra and normal coordinate analysis for two tautomers of 4(5)-(2′-furyl)-imidazole

Ledesma,Zinczuk,Gonzalez, J.J. Lopez,Altabef, A. Ben,Brandan

, p. 587 - 597 (2010)

We have synthesized both the 4 and 5 tautomeric forms of 4(5)-(2′-furyl)-imidazole (1) and investigated their molecular vibrations by infrared and Raman spectroscopies as well as by calculation based on the density functional theory (DFT) approach. Examination of the temperature dependence of IR intensity revealed the band characteristics of the 4 and 5 tautomersof(1).Comparisonofexperimentalandcalculatedchemicalshiftsinnucl earmagneticresonance(NMR)spectroscopy was made in order to identify the two tautomeric forms. The assignment of vibrational normal modes was performed, and the forcefieldobtainedreproduced theexperimentalvibrationalwavenumbers with a root mean-squaredeviation (RMSD)value of ca. 13 cm-1 for both tautomers. The natural bond orbital (NBO) study reveals the characteristics of the electronic delocalization of the two tautomeric structures.

Michael additions of oxygen and sulfur nucleophiles to 3,4-Di-t-butyl-1-[(p-tolyl)sulfonylimino]-1,1-dihydrothiophene. A comparison study with 3,4-Di-t-butylthiophene 1-oxide and 1,1-dioxide

Otani, Takashi,Sugihara, Yoshiaki,Ishii, Akihiko,Nakayama, Juzo

, p. 744 - 745 (2000)

The reactions of 3,4-di-t-butyl-1-[(p-tolyl)sulfonylimino]-1,1-dihydrothiophene with RONa and RSNa furnished 2-alkoxy-and 2-alkylthio-substituted thiophenes, respectively, through Michael adduct formation. The reaction of 3,4-di-t-butylthiophene 1-oxide with RSNa gave 1,6-Michael adducts, whereas the corresponding reaction of 3,4-di-t-butylthiophene 1,1-dioxide produced a mixture of 1,4-and 1,6-adducts.

Cyclopropyl aziridines: Solvolytic reactions of the N-tosylaziridines of (+)-2-carene and (+)-3-carene

Silverberg, Lee J.,Rabb, Javon M.,Reno, Joseph M.,He, Gang

, p. 193 - 199 (2014)

The N-tosylaziridine 4 of (+)-2-carene 1 was prepared and subjected to solvolytic reactions with weak protic acids. For comparison, the solvolytic reactions of cis-3-carene-N-tosylaziridine 8 were also studied. The solvolyses of 4 were more rapid than those of 8, and both rings were opened in 4, whereas only the aziridine was opened in 8. This leads to the conclusion that the aziridine and cyclopropane rings in 4 can achieve a conjugated transition state.

Diazabenzo[a]phenoxazone sulphonamides: synthesis, in-silico and in-vitro antimicrobial studies

Ezeokonkwo, Mercy A.,Eze, Cosmas C.,Okafor, Sunday N.,Onoabedje, Efeturi A.,Godwin-Nwakwasi, Evelyn U.,Ibeanu, Fidelia N.

, p. 2482 - 2493 (2018)

The syntheses of new sulphonamide derivatives of 8,10-diazabenzo[a]phenoxazones are reported. The condensation of 4,5-diamino-6-hydroxy-2-mercaptopyrimidine and 2,3-dichloro-1,4-naphthoquinone in a basic medium gave the key functional intermediate, 11-amino-6-chloro-9-mercapto-8,10-diazabenzo[a]phenoxazin-5-one. The conversion of the later compound to its sulphonamide derivatives was achieved via nickel catalyzed cross-coupling Buchwald-Hartwig protocol. Reaction between 11-amino-6-chloro-9-mercapto-8,10-diazabenzo[a]phenoxazin-5-one and various aryl sulphonamides and sulphonyl chlorides furnished eight new mono sulphonamide substituted diazaphenoxazone compounds. Subsequent coupling of mono sulphonamide substituted diazaphenoxazone compounds 5a-d with four different arylsulphonyl chlorides under similar reaction conditions gave the disubstituted derivatives 8a-d. The products were isolated in 74 – 88% yields and characterized by means of Uv-visible, FT-IR, 1H-NMR, 13C-NMR, and Mass spectroscopy. The synthesized compounds were screened for antimicrobial activity against bacterial strains: Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Salmonella typhi and Klebsiella pneumonia, and fungal strains, Aspergillus niger, and Candida albican, using agar-well diffusion method. The activities of the compounds were compared with that of colymycin, which is a strong antibacterial, and antifungal drug, Most of the compounds showed appreciable antimicrobial activities comparable with the activity of colymycin. The in silico study revealed that all the synthesized compounds showed significant binding affinity for both intact and mutated DNA gyrase. Compounds 8a and 5b showed the highest binding affinities of -12.31 and -13.30 kcal/mol for intact and mutated DNA gyrase respectively.

Data-Driven Identification of Hydrogen Sulfide Scavengers

Yang, Chun-tao,Wang, Yingying,Marutani, Eizo,Ida, Tomoaki,Ni, Xiang,Xu, Shi,Chen, Wei,Zhang, Hui,Akaike, Takaaki,Ichinose, Fumito,Xian, Ming

, p. 10898 - 10902 (2019)

Hydrogen sulfide (H2S) is an important signaling molecule whose up- and down-regulation have specific biological consequences. Although significant advances in H2S up-regulation, by the development of H2S donors, have been achieved in recent years, precise H2S down-regulation is still challenging. The lack of potent/specific inhibitors for H2S-producing enzymes contributes to this problem. We expect the development of H2S scavengers is an alternative approach to address this problem. Since chemical sensors and scavengers of H2S share the same criteria, we constructed a H2S sensor database, which summarizes key parameters of reported sensors. Data-driven analysis led to the selection of 30 potential compounds. Further evaluation of these compounds identified a group of promising scavengers, based on the sulfonyl azide template. The efficiency of these scavengers in in vitro and in vivo experiments was demonstrated.

Base Promoted Three-Component Annulation of 4-Diazoisochroman-3-imines with Dimethylsulfonium Ylides: Synthesis of Highly Functionalized Isochromeno[4,3- c]pyridazines

Suleman, Muhammad,Xie, Jianwei,Wang, Zaibin,Lu, Ping,Wang, Yanguang

, p. 455 - 465 (2021)

A novel method has been developed to synthesize a unique class of highly functionalized isochromeno[4,3-c]pyridazines. This reaction features an intermolecular functionalization of terminal nitrogen atom of diazo group of 4-diazoisochoman-3-imine with two dimethylsulfonium ylide components, followed by a base promoted 6-exo-trig cyclization step. Readily available starting materials, a broad substrate scope, and operationally simple, mild, and catalyst-free reaction conditions are the prominent features of this method.

Fine-tuning hydroxylamines as single-nitrogen sources for Pd(0)-catalyzed diamination of o-bromo(or chloro)-biaryls

Bai, Jiaxing,Ding, Pin,Han, Lingbo,Liu, Jingjing,Luan, Xinjun

, (2022/03/19)

Transition metal-catalyzed diamination by hydroxylamines is a common approach for making three-membered aziridines, while its use for building the larger N-heterocycles is still underdeveloped. Herein, we report an efficient Pd(0)-catalyzed inter-molecular [4+1] annulation of o-bromo(or chloro)-biaryls with bifunctional secondary hydroxylamines for the one-step assembly of synthetically useful carbazoles. Noteworthily, a linchpin for this domino reaction was the judicious selection of both the amino-sources and Pd(0)-catalysts for enabling the prerequisite oxidative addition of aryl halides to Pd(0)-species in the presence of hydroxylamines with a labile N-O bond.

Rajeswari, Panneer Selvam,Nagarajan, Rajendran,P, Sujith K,Emmanuvel, Lourdusamy

supporting information, (2020/12/03)

Synthesis of new copper catalyst with pyrazole based tridentate ligand and study of its activity for azide alkyne coupling were investigated by researchers. To a solution of acetyl acetone (2.002 g, 20 mmol), 2- nitrophenylhydrazine in ethanol was added five drops of con. HCl and heated at 50° for 1 hour. After confirming the formation of 3, 5-dimethyl-1-(2-nitrophenyl)- 1H-pyrazole by TLC, ice cooled water was added in to the reaction mixture. The precipitate was filtered, washed with water and then hexane. The product formed as yellow precipitate, that precipitate had been filtered by normal filter paper. The product was recrystallized in ethanol. For synthesis, was suspended in 6 mL of deionized and stirred for 4 h until a clear solution was obtained in 50 ml round bottom flask Cu(OAc) 2. The reaction mixture was diluted with water, filtered, washed sequentially with water, methanol and n-hexane. Then dark greenish blue color crystal were formed and used for the reactions. The solid was crystallized in CH2Cl2 to get crystal whose structure was confirmed by single crystal XRD.

Li, Tingting,Xu, Bo

supporting information, p. 2673 - 2678 (2021/08/03)

Main observation and conclusion: We describe a practical and general protocol for immobilization of heterogeneous catalysts to mechanically robust porous ultra-high molecular weight polyethylene tablets using inter-facial Lifshitz-van der Waals Interactions. Diverse types of powderous catalysts, including Cu, Pd/C, Pd/Al2O3, Pt/C, and Rh/C have been immobilized successfully. The immobilized catalysts are mechanistically robust towards stirring in solutions, and they worked well in diverse synthetic reactions. The immobilized catalyst tablets are easy to handle and reused. Moreover, the metal leaching of immobilized catalysts was reduced significantly.

Donepezil oxidation: complementary chemical and spectroscopic exploration of products, mechanism and kinetics

Anantharaju, K. S.,Malini, S.,Raj, Kalyan,Suresha, N.

, (2021/11/09)

Oxidation is a vital step of drug metabolism and hence a pharmaceutically relevant process. This study explores the potential of Donepezil, a widely used drug against mild to moderately severe Alzheimer's disease, to undergo oxidation using a mild, versatile oxidant Chloramine-T in acidic medium. A first-order dependency of rate on Donepezil and oxidant, fractional-order dependency on acid medium, independency of the rate on ionic concentration and an elevation of rate with increasing dielectric constant are revealed by the kinetic studies. The stoichiometry, thermodynamic properties, rate equation, mechanistic details are outlined, and identification of reaction products is supported by consistent oxidative degradation related UV, IR, 1H NMR and mass spectroscopic data. The spectroscopic results are in good agreement with theoretical predictions, providing an insight and deepen the understanding of oxidative metabolic pathway of Donepezil.
