Synthesis and anti-proliferative activity evaluation of novel benzo[d] [1,3] dioxoles-fused 1,4-thiazepines

Benzo[d][1,3]dioxoles 1,4-thiazepines remarkable antitumor activities, benzo[d][1,3]dioxoles-fused 1,4thiazepines, which combine two biologically active heterocyclic cores, are expected to be of pharmacological interest, We therefore envisaged that integrating 1,4-thiazepine and benzo[d][1,3]dioxole moieties in one molecular platform could potentially produce novel compounds with significant synergistic antitumor properties. A series of novel benzo[d][1,3]dioxoles-fused 1,4-thiazepines, designed via molecular hybridization approach, were synthesized in very good yields using one-pot condensation of 3,4-methylenedioxyaniline, aldehydes, and alpha-mercaptocarboxylic acids under solvent-free condition. The anti-proliferative activities of all the synthesized compounds were assessed on two different human cancer cell lines (Esophageal squamous cell carcinoma Ec9706 and Eca109), and the results showed that compound 4e showed the best anti-tumor activity with IC50 values of 8.23 mu M and 16.22 mu M against Ec9706 and Eca109 cell lines, respectively, which was 2-3 times more potent than 5-Fluorouracil (IC50 = 23.26 mu M and 30.25 mu M against Ec9706 and Eca109 respectively). These novel benzo[d][1,3] dioxoles fused with bioactive heterocyclic skeletons may find their pharmaceutical applications after further investigations. (C) 2017 Elsevier Masson SAS.

Amorphous Teflons AF as organophilic pervaporation materials transport of individual components

Permeation and sorption of various organic liquids (chlorinated hydrocarbons, lower alcohols, hydrocarbons, etc.) in amorphous copolymers of 2,2-bis-trifluoromethyl-4,5-difluoro-1,3-dioxole and tetrafluoroethylene (amorphous Teflons AF) were studied in the temperature range 5-95 degreesC. Based on permeation rate and solubility coefficients, the diffusion coefficients of organic penetrants in AF copolymers AF were estimated. It was shown that the copolymer with a higher content (87%) of the dioxole component (AF2400), as distinguished by a larger free volume, is much more permeable to liquids than the copolymer AF1600 containing 65% of the dioxole comonomer. In contrast, solubility of organic compounds in both copolymers is hardly affected by their composition. The effects of penetrant parameters, such as critical volume (V-c) and critical temperature (T-c) were analyzed. The variation in permeation rates of liquids and gases through these materials are consistent with a mobility (diffusion) controlled mechanism for mass transfer. A trade-off between the Arrhenius parameters for permeability and the van’t Hoff parameters for solubility is demonstrated for pervaporation. On this basis, novel correlations are obtained that enable a determination of the activation energy for permeation E-p and the enthalpy of sorption H-S from the permeability (P) and solubility (S) coefficients. Long term tests (up to 12 months) showed excellent time stability of the transport parameters, a property unexpected and quite important for a high flux, high free volume pervaporation material.

Benzodioxole derivatives as negative effectors of plant proteases

Previous work demonstrated that a commercial formulation of piperonyl butoxide (PBO) did inhibit the activity of some plant proteolytic enzymes. In this paper, the effect of pure PBO and nine pure PBO homologues (PBOH) appropriately synthesized toward bromelain and papain was studied in hydrocarbon solution using the bis(2-ethylhexyl)sodium sulfosuccinate (AOT) reverse micellar system. This study establishes that the majority of these compounds show, in vitro, interesting protease inhibition activities. The benzodioxole and dihydrobenzofuran structures, in particular, 5-[2-(2butoxyethoxy)ethoxymethyl]-benzo[1,3]dioxole (EN 1-40) and 6-[2-(2-butoxyethoxy)ethoxymethyl]5-propyl-2,3-dihydrobenzofuran (EN 16-5), respectively, appear to be responsible for protease inhibition. Measures of octanol/water partition coefficients on PBO and PBOH have demonstrated that water solubility plays a fundamental role in the expression of protease inhibition activity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18422-53-2 help many people in the next few years. Safety of 1,2:4,5-Di-O-Isopropylidene-Beta-D-Erythro-2,3-Hexodiulo-2,6-Pyranose.

Nuclear Spin Selective Torsional States: Implications of Molecular Symmetry

We consider a class of molecules with C-2 symmetry axis and three segments A, B, C which can rotate independently about that axis, corresponding to two independent torsions (B vs. A and C vs. B). The torsions may be feasible either in the electronic ground or in the excited states. We determine the corresponding molecular symmetry group, i.e. the Abelian group G(16)(A) representing 16 feasible permutations and permutation-inversions, and its permutation subgroup with eight permutations, together with their properties, e.g. their character tables and the corresponding 16 or 8 irreducible representations (IREPs), respectively. Accordingly, the molecules which belong to this class have at most eight different nuclear spin isomers (NSIs). A subset of them survives at low temperature, T -> 0. The corresponding NSI selective wavefunctions contain products of torsional times nuclear wavefunctions with specific IREPs. The NSIs are characterized by these IREPs. As an example, we determine the molecular symmetry adapted torsional wavefunctions of the model 2-[4-(cyclopenta-2,4-dien-1-ylidene)cyclohexa-2,5-dien-1-ylidene]-2H-1,3-dioxole, abbreviated as CCD. In order to demonstrate the principles of the derivations, we employ a simple model, with the C-2 symmetry axis oriented along the laboratory Z-axis, and with all degrees of freedom frozen in the equilibrium structure of CCD, except the two torsional degrees of freedom. The resulting torsional wavefunctions represent different NSIs of CCD, ready for subsequent applications, e.g. for demonstrations of NSI selective dynamics.

Design, synthesis and anti-HIV evaluation of 5-alkyl-6-(benzo[d][1,3] dioxol-5-alkyl)-2-mercaptopyrimidin-4(3H)-ones as potent HIV-1 NNRTIs

In order to discover and develop the new HIV-1 NNRTIs, a series of 5-alkyl-6-(benzo[d][1,3]dioxol-5-ylalkyl)-2mercaptopyrimidin-4(3H)-ones was synthesized and screened for their in vitro cytotoxicity against HIV-1. Most of the compounds we synthetized showed high activity against wild-type HIV-1 strain (IIIB) while IC50 values are in the range of 0.06-12.95 mu M. Among them, the most active HIV-1 inhibitor was compound 6-(benzo[d][1,3] dioxol-5-ylmethyl)-5-ethyl-2-((2-(4-hydroxyphenyl)-2-oxoethyl)thio)pyrimidin-4(3H)-one (5b), which exhibited similar HIV-1 inhibitory potency (IC50 = 0.06 mu M, CC50 = 96.23 mu M) compared with nevirapine (IC50 = 0.04 mu M, CC50 200 mu M) and most of compounds exhibited submicromolar IC50 values indicating they were specific RT inhibitors. The compounds 5b, 6-(benzo[d] [1,3]dioxol-5-yl)-5-ethyl-2-((2-(4-hydroxyphenyl)2-oxoethyl)thio)pyrimidin-4(3H)-one (5c) and 4-(2-((4-(benzo[d][1,3]dioxol-5-ylmethyl)-5-ethyl-6-oxo-1,6-dihydropyrimidin-2-yl)thio)acetyl)phenylbenzo[d][1,3]dioxole-5-carboxylate (5r) were selected for further study. It was found that all of them had little toxicity to peripheral blood mononuclear cell (PBMC), and had a good inhibitory effect on the replication of HIV-1 protease inhibitor resistant strains, fusion inhibitor resistant strains and nucleosides reverse transcriptase inhibitor resistant strains, as well as on clinical isolates. Besides, compound 5b and 5c showed inhibition of HIV-1 RT RNA-dependent DNA polymerization activity and DNA-dependent DNA polymerization activity, while compound 5r only showed inhibition of HIV DNA-dependent DNA polymerization activity, which was different from classical reverse transcriptase inhibitors. Our study which offered the preliminary structure-activity relationships and modeling studies of these new compounds has provided the valuable avenues for future molecular optimization.

Ultrafast chemistry of nanoenergetic materials studied by time-resolved infrared spectroscopy: Aluminum nanoparticles in teflon

Ultrafast mid-infrared (IR) spectroscopy is used to monitor chemical reactions initiated by flash-heating a nanoenergetic material consisting of 30 nm diameter Al nanoparticle fuel in a Teflon(AF) oxidizer. Teflon(AF) is a copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (dioxole), so Al can react with several different moieties. Transitions associated with CF2 stretching of TFE or CFO stretching or CF3 stretching of dioxole were monitored. The reactions of Al with CFO occurred with time constant (k(1))(-1) = 50 (+/- 20 ps); reactions of Al with CF2 or CF3 were more than 10 times slower, (k(2))(-1) = 0.7 (+/- 0.05 ns). An interesting frequency oscillation is seen in the 1148 cm(-1) band, where the peak frequency undergoes a time-dependent shift from 1148 to 1155 cm(-1) and then back to 1148 cm(-1). Due to the coincidence of CFO and CF2 stretching transitions, this band in the copolymer represents an amalgamated vibration with amplitude on both TFE and dioxole. As concentration is varied from pure dioxole to pure TFE, the band blue-shifts. A kinetic scheme and a model for the concentration dependence of the amalgamated vibration frequency are developed, which show that the frequency oscillation is a consequence of the arrangement of reactants on the nanoscale, which creates two types of oxidizer. The type adjacent to the Al nanoparticle is in a region of high local fuel concentration, while the other type is too distant from the fuel to react.
