SAR of 2,6-diamino-3,5-difluoropyridinyl substituted heterocycles as novel p38 MAP kinase inhibitors

2,6-Diamino-3,5-difluoropyridinyl substituted pyridinylimidazoles, -pyrroles, -oxazoles, -thiazoles and -triazoles have been identified as novel p38alpha inhibitors. Pyridinylimidazole 11 potently inhibited LPS-induced TNFalpha in mice, showed good efficacy in the established rat adjuvant (ED50: 10 mg/kg po b.i.d.) and collagen induced arthritis (ED50: 5 mg/kg po b.i.d.) with disease modifying properties based on histological analysis of the joints.

The identification of a nitrosated prodrug of the PDE-5 inhibitor aildenafil in a dietary supplement: A Viagra with a pop

A new unapproved analogue of sildenafil was detected in capsules of a herbal dietary supplement promoted as a libido enhancing product. Using LC-DAD-MS, MS-MS, HRMS, IR and NMR the analogue was shown to be a derivative of the PDE-5 inhibitor aildenafil with a nitrosamine moiety. A hydrolysis experiment showed that the new analogue was a prodrug of aildenafil and was therefore named nitroso-prodenafil. A capsule contained 108 mg of nitroso-prodenafil which is equivalent to 84 mg of aildenafil and 5.1 mg of nitrogen monoxide (NO). Although it is unknown how much NO can be usefully generated there is 3-fold more NO present than in a 10 mg isorbide nitrate tablet. Both PDE-5 inhibitors and nitrosamines cause vasodilatation by increasing levels of NO. To their coincidental use is warned against because it may cause a fatal drop in blood pressure. In addition, nitrosamines are known carcinogens. This is the first time a PDE-5 inhibitor and a potential NO donor were identified in one molecule. The findings indicate the dangerous level of advancement in medicinal chemistry by producers of unapproved drugs.

Optimization studies of microwave-induced co-pyrolysis of empty fruit bunches/waste truck tire using response surface methodology

The central composite design of RSM was utilised for the optimization of experimental conditions of microwave-assisted co-pyrolysis of empty fruit bunch (EFB) and waste truck-tire (TT) to maximise the co-pyrolysis oil and energy yield. The predicted maximum co-pyrolysis oil of 40.0 wt% and energy yield of 59.0% were obtained at the optimum conditions of 505 C pyrolysis temperature, 65.0% of EFB ratio and 60.0 g of activated carbon loading. The reaction temperature and TT ratio in EFB feedstock were identified as the most significant variables that affect the oil and energy yield. A design of experiment was performed to determine the quality of liquid oil. The result indicates the co-pyrolysis oil (PO65) properties were significantly improved after adding TT to EFB biomass. Olefin-rich pyrolytic oil (39.0%) with high selectivity of D-limonene was produced (28.6%). While, the oxygenates and polyaromatics hydrocarbon were reduced to 9.9% and 7.4%, respectively. The energy recovery analysis shows that the optimised co-pyrolysis oil (PO65) was 20.0% higher as compared to the TT alone. In view of the improved yield and quality of co-pyrolysis oil (PO65), this work shows that co-pyrolysis of EFB/TT presents a viable method to produce diesel-like fuel using the microwave-assisted heating method.

A new size-expanded RNA alphabet: Computational design of benzo-homologated (xtz-) isothiazole RNA and comparisons to the x-thieno RNA

Fluorescent nucleobase analogs are of great interest because of their widespread applications in nucleic acids research. In the present work, a new benzo-homologated RNA alphabet comprising xtzA, xtzG, xtzC, and xtzU was computationally designed based on the isomorphic tz-bases. The structural, electronic, and photophysical properties are studied by means of DFT and TDDFT calculations, and the effects of water solution, ribose, and base pairing on the singlet excited transitions were examined. The results are compared with those for tz-bases and xth-bases. These new base analogs can form stable Watson-Crick base pairs with natural counterparts as tz-bases and xth-bases do. Their ionization potentials and HOMO-LUMO gaps are in the middle of tz-bases and xth-bases: xth-base < xtz-base < tz-base. Furthermore, all xtz-bases are predicted to have smaller IPs and HOMO-LUMO gaps than natural bases and tz-bases, they are suggested to be candidates for applications in nanowire technology. The S1 states for all xtz-bases are revealed to be pipi* dominated by the configuration HOMO ? LUMO. In water solution, compared with tz- or xth-bases, the lowest pipi* states are about 20.06?21.91 kcal/mol red-shifted or 0.92?4.15 kcal/mol blue-shifted, respectively. Linking to ribose has negligible effects on the S1 excitation energies, but it owns a larger impact on the corresponding oscillator strengths. Base pairing and water solution as a whole has very little effects on the S1 transition energies of xtzA and xtzC, but it will red-shift those for xtzG and xtzU by 6.69 and 5.30 kcal/mol, respectively. All xtz-bases are expected to display visible fluorescence with the wavelengths predicted to be 540, 585, 524, and 506 nm for xtzA, xtzG, xtzC and xtzU, respectively, in water solution. Though structurally very similar, the excitation maxima and fluorescence emissions of xtz- and xth-bases show distinct differences, allowing them to be distinguished from each other by their spectroscopic characters Do you like my blog?

THE N-H STRETCHING REGION OF SOME IMIDES AND THIOIMIDES

The multiplet structure of nuN-H and nuN-D bands of solid phthalimide, monothiophthalimide, dithiophthalimide, isatin, saccharin and of their deuterated analogues has been explained as being a result of Fermi resonance of the fundamentals of nuN-H ans nuN-D with combinations and/or overtones.The submaxima of 3080 and 2970 cm-1 of saccharin as well as pronounced doublet at 2465 and 2345 cm-1 of d-phthalimide move to lower frequency in the low temperature ir spectra, while the “windows” remain fixed at 3045 and 2380 cm-1, respectively.These examples could be a striking demonstration of Evans type Fermi resonance.
