Solvolysis of Tris-p-nitrophenyl-phosphate in aqueous and reverse micelles

The widespread use of toxic phosphates and phosphonates as insecticides, and their use as chemical weapons, has led to investigation of fast detoxification and decontamination methods. Micelles, microemulsions, cyclodextrines and liposomes have been used to accelerate phosphate ester decomposition by nucleophiles. Here, hydrolysis, methanolysis and hexanolysis of Tris-p-nitrophenyl phosphate (TNPP), a model for reactive phosphate esters. were studied in homogeneous phase, aqueous and reverse micelles. Kinetic micellar effects were quantitatively analyzed using pseudo-phase models. TNPP hydrolysis was catalyzed by cetyltrimethylammonium chloride (CTAC), cetyltrimethylammonium bromide (CTAB). and hexadecylammonium propanesulfonate (HPS), micelles by factors of five, CTAC, and three. CTAB, HPS, respectively. The calculated rate constants for spontaneous and acetate-catalyzed hydrolysis in the micellar phase were significantly higher than those in the aqueous phase. While in water and in methanol the effect of the acetate cation was negligible, the catalytic efficiency of acetate for hexanolysis depended on the nature of the cation with the K+ salt being ca. 20 times more efficient than the tetraethylammonium salt in non-polar solvents. Sodium dodecylsulfate, SDS. micelles inhibited TNPP hydrolysis by a factor of eigth. Reverse micelles of CTAB in n-hexanol/isooctane (10:90, v/v) did not catalyze TNPP hydrolysis, but changed the bis-p-nitrophenyl phosphate/hexyl-bis-p-nitrophenylphosphate product ratio depending of CTAB concentration and water/detergent ratio.

Multi-pharmacophore Approach to Bio-therapeutics: Piperazine Bridged Pseudo-peptidic Urea/Thiourea Derivatives as Anti-oxidant Agents

In an attempt to develop synergetic, potential and selective anti-oxidant agents, a series of novel piperazine bridged pseudo-peptidic urea/thiourea derivatives (5a-x) are designed by molecular docking study, synthesized and evaluated for their in-vitro anti-oxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and dimethyl-4-phenylenediamine (DMPD) methods. The results revealed that compounds 5q, 5s, 5w and 5x are good anti-oxidant agents. Amongst, compounds with aromatic side chain, thioureal fragment with electron donating group-substitution, particularly, 5s and 5w are the most active members exhibiting remarkable anti-oxidant property. The docking results are complementary to the experimental results. The correlation study revealed that compounds derived from phenylalanine and tryptophan containing electron donating group are excellent antioxidants. [GRAPHICS] .

Influence of inter- and intramolecular hydrogen bonding on Kemp decarboxylations from QM/MM simulations

The Kemp decarboxylation reaction for benzisoxazole-3-carboxylic acid derivatives has been investigated using QM/MM calculations in protic and dipolar aprotic solvents. Aprotic solvents have been shown to accelerate the rates of reaction by 7-8 orders of magnitude over water; however, the inclusion of an internal hydrogen bond effectively inhibits the reaction with near solvent independence. The effects of solvation and intramolecular hydrogen bonding on the reactants, transition structures, and the rate of reaction are elucidated using two-dimensional potentials of mean force (PMF) derived from free energy perturbation calculations in Monte Carlo simulations (MC/FEP). Free energies of activation in six solvents have been computed to be in close agreement with experiment. Solute-solvent interaction energies show that poorer solvation of the reactant anion in the dipolar aprotic solvents is primarily responsible for the observed rate enhancements over protic media. In addition, a discrepancy for the experimental rate in chloroform has been studied in detail with the conclusion that ion-pairing between the reactant anion and tetramethylguanidinium counterion is responsible for the anomalously slow reaction rate. The overall quantitative success of the computations supports the present QM/MM/MC approach, which features PDDG/ PM3 as the QM method.

Synthesis and anti-HIV activity of new alkenyldiarylmethane (ADAM) non-nucleoside reverse transcriptase inhibitors (NNRTIs) incorporating benzoxazolone and benzisoxazole rings

The HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) constitute a large and structurally diverse set of compounds, several of which are currently used in the treatment of AIDS. A series of novel alkenyldiarylmethanes (ADAMs) were designed and synthesized as part of an ongoing investigation to replace the metabolically labile methyl ester moieties found in the ADAM pharmacophore with stable modifications that retain the potent anti-HIV activity of the parent compounds. Unsurprisingly, the rat plasma half-lives of the new ADAMs were not improved when compared to the parent compounds, but all of the synthesized ADAMs inhibited the cytopathic effect of HIV-1 in cell culture. The most potent compound identified was (E)-5-[1-(3,7-dimethyl-2oxo-2,3-dihydro-benzoxazol-5-yl)-5-methoxycarbonyl-pent-1-enyl]-2-methoxy-3-methylbenzoic acid methyl ester (7), which inhibited the cytopathic effects of both HIV-1(RF) and HIV-1(IIIB) strains in cell cultures with EC50 values of 30 and 90 nM, respectively, and inhibited HIV-1 reverse transcriptase with an IC50 of 20 nM.

Cytokinin-like activity of N ‘-substituted N-phenylureas

We have synthesized 14 N-phenylurea derivatives, differing in the heterocyclic portion linked in N’-position, and tested their cytokinin-like activity. Three different bioassays were used: the chlorophyll level determination test, the bioassay for the expression of hormone-induced chimeric Pg5-GUS gene and the tomato regeneration test, in which 1,2-benzisoxazole-3-acetic acid (BOAA) was utilized as auxin. The cytokinin-like activity showed by three of these compounds in the regeneration assay seems to be related to their different heterocyclic nature. Results obtained indicate that the N-phenyl-N’-1,3,4-thiadiazol-2-ylurea (compound 4), an isomer of N-phenyl-N’- 1,2,3-thiadiazol-5-ylurea (thidiazuron, TDZ), in the absence of auxin induces shoot regeneration in the 34,2% of the explants cultured; the N-plienyl-N’-(3-chloro-1,2-benzisothiazol-7-yl) urea (compound 10), structurally different from TDZ, in the absence of auxin induces shoot regeneration in the 25,9% of explants, significantly lower than that of TDZ (68,8%). N-phenyl-N’-benzothiazol-6-ylurea (compound 13), structurally different from TDZ, in the absence of auxin induces the 99,5% of shoot regeneration, significantly different from that of the other substances. The addition of auxin in the cotyledon regeneration assay reduces the differences. The compound 13 could be considered a new phenylurea derivative with a highly specific cytokinin-like activity.

Reactivity of Lithium beta-Ketocarboxylates: The Role of Lithium Salts

Lithium beta-ketocarboxylates 1(COOLi), prepared by the reaction of lithium enolates 2(Li+) with carbon dioxide, readily undergo decarboxylative disproportionation in THF solution unless in the presence of lithium salts, in which case they are indefinitely stable at room temperature in inert atmosphere. The availability of stable THF solutions of lithium beta-ketocarboxylates 1(COOLi) in the absence of carbon dioxide allowed reactions to take place with nitrogen bases and alkyl halides 3 to give alpha-alkyl ketones 1(R) after acidic hydrolysis. The sequence thus represents the use of carbon dioxide as a removable directing group for the selective monoalkylation of lithium enolates 2(Li+). The roles of lithium salts in preventing the disproportionation of lithium beta-ketocarboxylates 1(COOLi) and in determining the course of the reaction with bases and alkyl halides 3 are discussed.
