Novel Thiourea Derivatives Bearing Sulfonamide Moiety as Anticancer Agents Through COX-2 Inhibition

Background: Thiourea derivatives bearing sulfonamide moiety are well known for their anticancer activity. Objective: The anticancer activity of the target compounds was studied, via inhibition of COX-2 enzyme. Method: A series of novel thioureas 5a-n, 8, quinazoline 6, benzo[g] quinazoline 7 and benzo[1,3] dioxole 10, bearing a sulfonamide moiety was synthesized from the starting compound N-(2,6-dimethoxypyrimidin-4-yl)-4isothiocyanatobenzenesulfonamide 2. The target compounds were screened against HepG2, MCF-7, Caco-2, HCT-116, PC-3 cancer cell lines and VERO-B normal cell line. Results: Out of all the tested compounds, compound 5c showed a broad selective cytotoxicity against HepG2, MCF-7, Caco-2 and PC-3 cancer cells. Moreover, a sensitization assay was performed on Caco-2 cells, and compound 5c proved to act as a chemosensitizer for cisplatin on colon cancer (Caco-2) cells. The target compounds were further screened in vitro for their anti COX1/COX2 activity and investigated in vivo as antiinflammatory agents against carrageenan-induced rat paw oedema model. Conclusion: Compound 5g showed the most selective inhibitory activity against COX-2. While, compounds 5a, 6, 5m, 5n, 5g and 5i revealed significant anti-inflammatory effect as presented in carrageenan-induced oedema assay. Molecular docking of the tested compounds disclosed important binding modes which may be responsible for their anticancer activity via inhibition of the COX-2 enzyme.

Design and Synthesis of 5-Substituted Benzo[d][1,3]dioxole Derivatives as Potent Anticonvulsant Agents

A series of 5- substituted benzo[d][1,3] dioxole derivatives was designed, synthesized, and tested for anticonvulsant activity using the maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) screens. Neurotoxicity was determined by rotarod test. In the preliminary screening, six compounds, 3a, 3c, 3d, and 4d- f, showed promising anticonvulsant activities in the MES model, and compounds 4c and 4d exhibited full protection against seizures at doses of 300 mg/kg in the scPTZ model. Among the synthesized compounds, 3c as the most active compound showed high protection against the MES- induced seizures with an ED50 value of 9.8 mg/kg and a TD50 value of 229.4 mg/kg after intraperitoneal injection into mice, thus providing compound 3c with a high protective index (TD50/ED50) of 23.4 comparable to those of reference antiepileptic drugs.

Gas sorption, diffusion, and permeation in poly(2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole-co-tetrafluoroethylene)

The solubility and permeability of H-2, O-2, N-2, CO2, CH4, C2H6, C3H8, CF4, C2F6, and C3F8 in TFE/BDD87, a random copolymer prepared from 87 mol % 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole [BDD] and 13 mol % tetrafluoroethylene [TFE], are reported as a function of temperature and pressure. Sorption isotherms of all penetrants except hydrogen are concave to the pressure axis and are well described by the dual-mode model. Hydrogen exhibits linear sorption isotherms. In contrast to previous results in hydrocarbon-rich polymers, the solubility of perfluorocarbon penetrants is higher in TFE/BDD87 than that of their hydrocarbon analogues. The solubility of all penetrants in TFE/BDD87 decreases with increasing temperature. Enthalpies of sorption become more negative as penetrant size increases. Fluorocarbon enthalpies of sorption at infinite dilution are significantly more exothermic than those of their hydrocarbon analogues, suggesting more favorable interactions between fluorocarbon penetrants and perfluorinated TFE/BDD87 than between hydrocarbon penetrants and this polymer. Perfluorocarbon permeability coefficients are nearly an order of magnitude lower than those of their hydrocarbon analogues due to the larger size of the fluorocarbons and their subsequently lower diffusivities. The permeability of TFE/BDD87 increases with increasing temperature, indicating that activation energies of permeation (E-p) are positive. E-p values in TFE/BDD87 are smaller than those of conventional glassy polymers. Diffusion coefficients of the lower sorbing gases (O-2, N-2, CO2, CH4, CF4) exhibit a concentration dependence that is consistent with dual-mode transport in unplasticized glassy polymers. For more strongly sorbing C2H6, C3H8, C2F6, and C3F8, diffusion coefficients increase exponentially with increasing penetrant concentration, suggesting plasticization. Activation energies of diffusion in TFE/BDD87 are positive and increase linearly with penetrant diameter squared. Relative to conventional glassy polymers, E-D values in TFE/BDD87 are low. However, E-D is larger than Delta H-S. TFE/BDD87 is easily plasticized by the larger, more soluble penetrants and is susceptible to penetrant-induced conditioning. The level of conditioning is highest for the largest, most soluble penetrant examined (C3F8), and the conditioned state gradually relaxes toward that of the as-cast state.

2-Spiroanellated 1,3-benzodioxoles from the reaction of 2,3-dihydro-1H-pyrrol-3-ones with tetrachloro-1,2-benzoquinone

Novel spiro[1,3-benzodioxole-2,2′-(2,3′-dihydro-1’H-pyrrol-3′-ones)] were obtained from 2-aminomethylene-2,3-dihydropyrrol-3(1H)-ones and tetrachloro- 1,2-benzoquinone in ethanol at room temperature. However, in addition, 3,4-dichloro-7-methoxy-5-(4-methoxyphenyl)-5,10-dihydrophenazine-1,2-dione was formed in the reaction of 1-(4-methoxyphenyl)-2-(4-methoxyphenylaminomethylene)-4,5 -diphenyl- 1,2-dihydropyrrol-3-one with tetrachloro-1,2-benzoquinone.

Synthetic strategies towards the carbenoid reactions of alpha,beta-acetylenic carbonyls

Catalytic reactions of alpha, beta-conjugated carbonyl compounds have been a practical tool towards the synthesis of different useful heterocyclic compounds. Despite the numerous reactions with carbon-carbon double bond conjugated carbonyls, reactions of acetylenic carbonyls are limited. In this study, efficient dioxole synthesis was carried out via acetylenic aldehydes and butadiene formation was preferred over cyclopropene formation via acetylenic esters as different functional groups on these substrates change the product distribution. Both reaction conditions (such as solvent and temperature) and electrophilic structure of metal carbenoids alter the product distribution; acceptor (A), donor-acceptor (DA), and acceptor-acceptor (AA) functionalized diazo compounds yield different product types over different mechanisms.

Substituent effect on the dynamics of the inclusion complex formation between protoberberine alkaloids and cucurbit[7]uril

The kinetics of entry into and exit from the cavity of cucurbit[7]uril (CB7) was studied by the stopped-flow method in water at various temperatures using pharmaceutically important natural isoquinoline alkaloids as guest compounds. The rate constant of the alkaloid-CB7 complex dissociation was separately determined exploiting the very strong competitive binding of the 1-adamantylammonium cation to CB7. The enthalpy and entropy of activation for the release of berberine from CB7 were significantly lower than those found in the case of the other alkaloids, suggesting different dissociation dynamics. CB7 initially moved from the energetically most stable position encompassing the isoquinoline moiety of berberine to the smaller benzodioxole part, which could leave the macrocycle with less structural distortion. Despite the same thermodynamic parameters of berberine and palmatine inclusion, the latter compound was encapsulated in and set free from CB7 much slower due to the more substantial steric hindrance. The most rapid entry into CB7 and the most exothermic binding were found for epiberberine and coptisine, the alkaloids substituted with the less spacious dioxole ring on their isoquinoline moiety.

3-Amino-1-(2H-1,3-benzodioxol-5-yl)-9,10-dihydrophenanthrene-2,4-dicarbonitrile

In the title compound, C23H15N3O2, significant deviations from planarity are evidenced in the values of the dihedral angles formed between the amino-benzene ring and the benzene rings of the 1,3-benzodioxole [65.38 (12)degrees] and 1,2dihydronaphthalene [26.27 (14)v] residues; the dioxole ring has an envelope conformation with the methylene-C being the flap atom. The amino-H atoms form hydrogen bonds to one of the dioxole-O atoms and to one of the cyano-N atoms to generate a two-dimensional array with a zigzag topology that stacks along the ((1) over bar 0 2) plane.

Synthesis of new functionalized alizarins from alizarin, acetylenic esters, and phosphorus nucleophiles

The 1:1 intermediate generated by the addition of triphenylphosphine to dialkyl acetylenedicarboxylates is trapped by alizarin to produce alkyl 6,11-dihydro-12-hydroxy-2,6,11-trioxo-2H-naphtho[2,3-g]chromene-4-carboxylates in good yields. When ethyl propiolate was used, the reaction afforded ethyl 6,11-dihydro-6,11-dioxoanthra[1,2-d][1,3]-dioxole-2-acetate. The reaction of dialkyl acetylenedicarboxylates, alizarin, and trialkyl phosphites produced dialkyl 2-(dialkoxyphosphoryl)-3-(9,10-dihydro-1-hydroxy-9,10-dioxoanthracen-2-yloxy)succinates.
