Studies on nonlinear optical polyurethanes containing heterocyclic chromophores

This paper presents the synthesis of highly stable nitro-substituted thiazole, benzothiazole and thiadiazole chromophores. With these, a series of second-order nonlinear optical (NLO) responsive polyurethanes were successfully synthesized from tolylene-2,4-diisocyanate (TDI) and 4,4?- methylenedi(phenyl isocyanate) (MDI). Molecular structural characterization of these polyurethanes was achieved by 1H NMR, FT-IR, GPC and analytical data. The weight-average molecular weights (Mw) of the resulting polyurethanes were determined by GPC and ranged between 22,100 and 26,700. All the polyurethanes were highly soluble in aprotic solvents such as tetrahydrofuran, cyclohexanone, N,N-dimethylformamide, N,N-dimethylacetamide, dimethylsulphoxide, N-methyl-2-pyrolidinone, etc. The thermal behaviour of these polyurethanes was investigated using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Their glass transition temperatures were in the range 140-165 C and most of the polymers showed high thermal stability. With an in situ poling and temperature ramping technique, the optimal temperatures (Topts) for corona poling were determined for the largest second-order NLO response. The second harmonic generation (SHG) coefficients (d33) of the poled polyurethane films range from 62.21 to 103.11 pm/V at 1064 nm. All the poled films showed outstanding orientational stability up to 120 C without any measurable decay in the SHG signal. Of these, the polyurethane with nitro-substituted benzothiazole moiety (IIb) showed the best dynamical thermal stability of the poling-induced dipole alignment up to ?150 C.

Thermal analysis of a polymorphic azo dye derived from 2-amino-5-nitrothiazole

An azo dye, derived from 2-amino-5-nitrothiazole and a substituted N,N-dimethyl aniline, was studied by various techniques. Two sets of proton signals were obtained by NMR in CDCl3 solution, suggesting that two polymorphs coexist, however, only one set of signals is observed in DMSO solution. Differential scanning calorimetry and thermogravimetric analysis were used to confirm the existence of two forms. The events registered during thermal treatment of a sample were assigned to a glass transition, recrystallization and fusion of crystalline compounds. Hot-stage microscopy was used to obtain images of the dye samples at various stages of the heating program and these observations support the interpretation of the calorimetric results.

ORGANIC SYNTHESIS USING ORGANOSULFUR-NITRITES AND -NITRATES

Thionitrites or thionitrates have been considered to be unstable.However, bulky groups’ thio-NOn such as t-butylthio-nitrites and -nitrates have been readily synthesized and found to be stable enough for the use of the useful organic syntheses as an excellent nitrosation and diazotization reagents under mild conditions.Direct conversion of amines to the corresponding halides in the presence of copper halides (II), fluorination of heterocyclic amines in the presence of sodium tetrafluoroborate, alpha- oximation of methylene groups in ketones, facile cleavage of C=N bond to ketones, and desulfurization of thioacetals and thioketals, and other useful organic syntheses are described.

Novel anthraquinone derivatives with redox-active functional groups capable of producing free radicals by metabolism: Are free radicals essential for cytotoxicity?

The mode of action of antitumour anthraquinone derivatives (i.e. mitoxantrone) is not clearly established yet. It includes, among others, intercalation and binding to DNA, bioreduction and aerobic redox cycling. A series of anthraquinone derivatives, with potentially bioreducible groups sited in the side chain, have been synthesized and biologically evaluated. Their redox and cytotoxic activities were screened. Derivatives which bear a 2-(dimethylamino)ethylamino substituent, known to confer high DNA affinity, demonstrated cytotoxicity but not redox activity (beside the anthraquinone reduction). Conversely, derivatives which showed redox activity were not cytotoxic toward the P388 cell line. The results suggest that bioreduction is not the main mode of action in the cytotoxicity of anthraquinones.

3,6-Disubstituted carbazole chromophores containing thiazole and benzothiazole units: Synthesis, characterization and first-order hyperpolarizabilities

3,6-Disubstituted carbazole chromophores containing thiazole and benzothiazole units were synthesized and characterized by NMR, IR, and UV. The first-order hyperpolarizabilities (beta) were calculated via solvatochromic method. Our experiments suggest that the incorporation of thiazole and benzothiazole into carbazole-based chromophores can allow for significant enhancement of molecular hyperpolarizabilities. Nonlinear optical properties of ApiDpiA carbazole chromophores are superior to those of the corresponding DpiA aryl compounds.

Discovery and structure optimization of a series of isatin derivatives as Mycobacterium tuberculosis chorismate mutase inhibitors

In this study, the crystal structure of the Mycobacterium tuberculosis (MTB) enzyme chorismate mutase (CM) bound to transition state analogue (PDB: 2FP2) was used as a framework for virtual screening of the BITS-Pilani in-house database (2500 compounds) to identify new scaffold. We identified isatin as novel small molecule MTB CM inhibitors; further twenty-four isatin derivatives were synthesized and evaluated in vitro for their ability to inhibit MTB CM, and activity against M. tuberculosis as steps towards the derivation of structure-activity relationships (SAR) and lead optimization. Compound 3-(4-nitrobenzylidene)indolin-2-one, 24 emerged as the most promising lead with an IC50 of 1.01 ± 0.22 mum for purified CM and MIC of 23.5 mum for M. tuberculosis, with little or no cytotoxicity. 2D interaction profile of compounds 1, 7 and 25 with the active site residues.

We synthesized four 5-nitrothiazole (1-4) and four 6-nitrobenzothiazole acetamides (5-8) using an easy two step synthetic route. All compounds were tested in vitro against amitochondriate parasites Giardia intestinalis and Trichomonas vaginalis, showing excellent antiprotozoal effects. IC50’s of the most potent compounds range from nanomolar to low micromolar order, being more active than their drugs of choice. Compound 1 (IC50 = 122 nM), was 44-times more active than Metronidazole, and 10-fold more effective than Nitazoxanide against G. intestinalis and showed good trichomonicidal activity (IC50 = 2.24 muM). This compound did not display in vitro cytotoxicity against VERO cells. The in vitro inhibitory effect of compounds 1-8 and Nitazoxanide against G. intestinalis fructose-1,6-biphosphate aldolase (GiFBPA) was evaluated as potential drug target, showing a clear inhibitory effect over the enzyme activity. Molecular docking of compounds 1, 4 and Nitazoxanide into the ligand binding pocket of GiFBPA, revealed contacts with the active site residues of the enzyme. Ligand efficiency metrics of 1 revealed optimal combinations of physicochemical and antiprotozoal properties, better than Nitazoxanide.
