Taburnaemines A-I, Cytotoxic Vobasinyl-Iboga-Type Bisindole Alkaloids from Tabernaemontana corymbosa

Nineteen vobasinyl-ibogan-type bisindole alkaloids, including nine new compounds, taburnaemines A-I (1-9), were isolated from the twigs and leaves of Tabernaemontana corymbosa. The structures and absolute configurations of the new alkaloids were determined by a combination of MS, NMR, and ECD analyses. Alkaloids 1-5 contain a rare 1,3-oxazinane moiety in the vobasinyl unit, while 6 has an uncommon 1,3-oxazolidine moiety in the iboga unit. The absolute configurations of alkaloid 1 and the known alkaloid tabernaecorymbosine A (10) were confirmed by single-crystal X-ray diffraction analysis. All of the bisindole alkaloids, except 2 and 16′-decarbomethoxytabernaecoryrnbosine A (14), showed antiproliferative activity (IC50 2.6-9.8 mu M) against several human cancer cell lines, including A-549, MDA-MB-231, MCF-7, KB, and P-glycoprotein-overexpressing multidrug-resistant KB cells. The preliminary structure-activity relationship correlations are also discussed.

Zinc and thiocyanate-mediated oxazolidine ring formation in a trinuclear zinc(II) complex: Synthesis, structure, and properties

A novel trinuclear zinc(II) complex, [Zn3L2(NCS)(2)], where L is the deprotonated form of 2-(3-(2-(2-hydroxy-3-methoxybenzylideneamino)ethyl)oxazolidin-2-yl)-6-methoxyphenol (H2L), has been unexpectedly prepared from the reaction of Schiff base ligand 2-((2-(2-hydroxyethylamino)ethylimino)methyl)-6-methoxyphenol (HL’) with 3-methoxysalicylaldehyde, ammonium thiocyanate, and zinc nitrate in methanol. The complex has been characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction studies. It is interesting that the Schiff base ligand HL’ used to prepare the complex was transferred to a novel ligand H2L, bearing newly formed oxazolidine ring. Zinc ion and thiocyanate anion may be the essential factors for the cyclorization. Thermal stability and fluorescent property of the complex were also studied. (c) 2013 Elsevier B.V.

Highly Z-selective synthesis of 1,3-oxathiol-2-ylidenes and 4-methylene-oxazolidine-2-thiones via atom-specific 5-exo-dig cyclization of propargyl alcohol with isothiocyanate

DBU mediated 5-exo-dig cyclization of isothiocyanate and propargyl alcohol leading to valuable heterocyclic compounds has been accomplished. The different modes of nucleophilicity (either S-selective or N-selective) of isothiocyanates were found to depend on the substitution pattern of propargyl alcohol. The terminal propargyl alcohol and isothiocyanate underwent an N-nucleophilic attack to afford 3-substituted 4-methylene oxazolidine-2-thiones. In contrast, exclusive S-nucleophilic cyclization was observed with internal propargyl alcohol to produce (Z)-1,3-oxathiol-2-ylidenes and (Z)-N-(Z)-4-ethylidene-1,3-oxathiolan-2-ylidenes from secondary and primary propargyl alcohols, respectively. The formation of high Z-selectivity in the imine motif and alkene is the highlight of this new method as multiple selectivities over C = N and C = C in a single system are synthetically highly challenging. The Z-selectivity in imine and alkene may be attributed to electronic and steric factors respectively.

SERINOL DERIVATIVES FOR THE SUSTAINABLE VULCANIZATION OF DIENE ELASTOMERS

2-amino-1,3-propandiol (serinol) was used as the starting building block of synthetic pathways that led to the preparation of innovative chemicals suitable as ingredients for rubber compounds. Serinol based reactions were performed in the frame of a sustainable process, in the absence of any solvent and catalyst, with aldehydes and ketones, such as acetone, cinnamaldehyde and camphor. The synthesis of either imines or oxazolidines was obtained with high selectivity. Serinol, imine and oxazolidine derivatives of serinol were used as accelerator for the vulcanization of diene rubbers. They were proved to be efficient secondary accelerators in silica based compounds based on poly(styrene-co-butadiene) in place of diphenyl guanidine. The kinetics of vulcanization was investigated for natural rubber based compounds in the absence of any filler. With respect to serinol, the imine derivatives were able to enhance the induction time of vulcanization and to afford a similar vulcanization rate.

Spectrophotometric simultaneous determination of metal ions in cows’ milk and vegetables with the aid of artificial neural networks using synthetic 2-benzylspiro[isoindoline-1,5′-oxazolidine]2′,3,4′-trione

BACKGROUND: A simple, selective and sensitive multi-component method for the simultaneous determination of Zn2+, Mn2+ and Fe3+ based on complex formation with 2-benzylspiro[isoindoline-1,5-oxazolidine]-2,3,4-trione using artificial neural networks is proposed. RESULTS: The analytical data showed that metal-to-ligand ratios in Zn2+ and Fe3+ complexes was 1:1 and for Mn2+ complex was 1:2. It was found at pH 6.5 and 5 min after mixing, the complexation reactions were completed. The coloured complexes exhibited absorption bands in the wavelength range 200-400 nm. The results showed that Zn2+, Mn2+ and Fe3+ could be determined in the range 0.1-18.0, 0.3-10.0 and 0.5-20.0 mg L-1, respectively. CONCLUSION: The data obtained from synthetic mixtures of metal ions were processed by radial basis function networks (RBFNs) and back-propagation neural network. The optimal conditions of the neural networks were obtained by adjusting various parameters. Satisfactory precision and accuracy were obtained with all networks, although, because of surprisingly lower root mean square error (%) values, RBFNs were the preferred approach. The proposed approach was tested by analysing the composition of the different mixtures containing Zn2+, Mn2+ and Fe3+. The proposed method was successfully applied to the simultaneous determination of Zn2+, Mn2+ and Fe3+ ions in milk and vegetable samples. (c) 2013 Society of Chemical Industry

Mefloquine and its oxazolidine derivative compound are active against drug-resistant Mycobacterium tuberculosis strains and in a murine model of tuberculosis infection

Repurposing of drugs to treat tuberculosis (TB) has been considered an alternative to overcome the global TB epidemic, especially to combat drug-resistant forms of the disease. Mefloquine has been reported as a potent drug to kill drug-resistant strains of Mycobacterium tuberculosis. In addition, mefloquine-derived molecules have been synthesised and their effectiveness against mycobacteria has been assessed. In this work, we demonstrate for the first time the activities of mefloquine and its oxazolidine derivative compound 1E in a murine model of TB infection following administration of both drugs by the oral route. The effects of associations between mefloquine or 1E with the clinically used antituberculosis drugs isoniazid, rifampicin, ethambutol, moxifloxacin and streptomycin were also investigated. Importantly, combination of mefloquine with isoniazid and of 1E with streptomycin showed a two-fold decrease in their minimum inhibitory concentrations (MICs). Moreover, no tested combinations demonstrated antagonist interactions. Here we describe novel evidence on the activity of mefloquine and 1E against a series of quinolone-resistant M. tuberculosis strains. These data show MICs against quinolone-resistant strains (0.5-8 mu g/mL) similar to or lower than those previously reported for multidrug-resistant strains. Taking these results together, we can suggest the use of mefloquine or 1E in combination with clinically available drugs, especially in the case of resistant forms of TB.
