Bisadduct isomers of a H(2)@C(60) derivative with nitroxide addends have been synthesized, isolated and characterized. The (1)H NMRs of endohedral H(2) of the major isomers show well-separated chemical shifts, which could be useful for structural assignment and identification of the purity of the C(60) bisadduct isomers.

We compared the differential effects of positional isomers of acetylsalicylic acid (o-ASA, m-ASA, and p-ASA) on cyclooxygenase (COX) inhibition, gastric prostaglandin E2 (PGE2), malondialdehyde, tumor necrosis factor-alpha (TNF-α) levels, superoxide dismutase (SOD) activity, human adenocarcinoma colon cancer cell growth inhibition, cell proliferation, apoptosis, and cell-cycle progression. We a...

Two earlier crystal structure predictions (CSP) of aminophenol compounds are checked against experimental structure determinations. One of the predictions classified originally as ‘‘good’’ is verified and is now seen to be somewhat correct. The other prediction, which was classified earlier as ‘‘unclear’’, is incorrect. The two experimental crystal structures are characterized by small and larg...

A 47-year-old woman, after being exposed to nitrobenzene for 17 months, was admitted to hospital because of headache, nausea, cyanosis, and general weakness. Laboratory study revealed, in addition to methaemoglobinaemia, the presence of p-aminophenol as well as p-nitrophenol in the urine. Both compounds gradually disappeared from the urine during the two weeks after she was removed from the tox...

In the present study, a novel series of N-[4-(2-piperidine-1-yl-ethoxy) phenyl]acetamides were synthesized from 4-aminophenol and characterised by IR, H-NMR, Mass spectral studies and elemental analysis. The antimicrobial potency of compounds is tested against variety of fungal and bacterial strains by disc agar diffusion technique. in comparison to to fluconazole and chloramphenicol respective...

Positional isomers of decenoic, dodecenoic, and tetradecenoic acids of human adipose tissue have been separated by gas-liquid chromatography and their amounts determined by oxidative cleavage. The following acids have been shown to be present: 7-decenoic, 8-decenoic, 9-decenoic, 7-, 8-, and 9-dodecenoic, and 7-, 8-, 9-, and 11-tetradecenoic acids. Among all isomers of the even-numbered acids fr...

Static quadrupole moments (0) of 8+ isomers in 88 90Zr and the 2' + isomer in 9'Zr, as well as 0 ratios of 8+ isomers in Mo, have been measured with the time-differential perturbedangular-distribution technique. The isomers were excited by pulsed heavy-ion beams and recoil implanted into single crystals of Zr in which their quadrupole precession was observed. Our results, the first such data fo...
