"In-loop" 18 F-fluorination: A proof-of-concept study.
Dahl K, Garcia A, Stephenson NA, Vasdev N. Dahl K, et al. J Labelled Comp Radiopharm. 2019 Jun 15;62(7):292-297. doi: 10.1002/jlcr.3751. J Labelled Comp Radiopharm. 2019. PMID: 31083778
Initial development of the "in-loop" [(18) F]fluorination method was optimized by reacting [(18) F]triflyl fluoride with 1,4-dinitrobenzene to form [(18) F]1-fluoro-4-nitrobenzene. This methodology was then applied for the syntheses of two well-known radiopha …

Metabolism of nitroaromatic compounds.
Rickert DE. Rickert DE. Drug Metab Rev. 1987;18(1):23-53. doi: 10.3109/03602538708998299. Drug Metab Rev. 1987. PMID: 3311683 Review.
It is the major route of metabolism for 1,2-dinitrobenzene but is not an important route for 1,3- or 1,4-dinitrobenzene in hepatocytes. Tetrachloronitrobenzene isomers in which the nitro group is flanked by chlorines and pentachloronitrobenzene undergo nitro …

This study assessed the fertility potential of methanol leaf extract of Glyphaea brevis (MGB) in rats exposed to 1,4-Dinitrobenzene (DNB), an environmental reprotoxicant. Male Wistar rats were orally exposed to 50 mg/kg DNB and administered 750 mg/kg MGB, 150 …

Grinding-induced supramolecular charge-transfer assemblies with switchable vapochromism toward haloalkane isomers.
Wu JR, Wu G, Li D, Li MH, Wang Y, Yang YW. Wu JR, et al. Nat Commun. 2023 Sep 23;14(1):5954. doi: 10.1038/s41467-023-41713-9. Nat Commun. 2023. PMID: 37741830 Free PMC article.
Here we show a switchable on-off type vapochromic system toward 1-/2-bromoalkane isomers by constructing solid-state charge-transfer complexes between electron-rich perethylated pillar[5]arene and electron-deficient aromatic acceptors including 4-nitrobenzonitrile and 1, …

Mechanisms of the oxidations of NAD(P)H model Hantzsch 1,4-dihydropyridines by nitric oxide and its donor N-methyl-N-nitrosotoluene-p-sulfonamide.
Zhu XQ, Zhao BJ, Cheng JP. Zhu XQ, et al. J Org Chem. 2000 Dec 1;65(24):8158-63. doi: 10.1021/jo000484h. J Org Chem. 2000. PMID: 11101368
Replacement of HEH by N-d-HEH and HEH-4,4-d(2) to react with NO, MNTS and DDQ gave the observed kinetic isotope effects of 3.1 and 1.4 for NO, 1.1 and 1.3 for MNTS, and 1.1 and 2.1 for DDQ, respectively. When p-dinitrobenzene, an electron-transfer inhibitor, was add …

Reactions of 1- and 2-Halo- and 1,2-Dichloroadamantanes with Nucleophiles by the S(RN)1 Mechanism.
Santiago AN, Stahl AE, Rodriguez GL, Rossi RA. Santiago AN, et al. J Org Chem. 1997 Jun 27;62(13):4406-4411. doi: 10.1021/jo960965u. J Org Chem. 1997. PMID: 11671767
All these reactions can be explained by the S(RN)1 mechanism as they did not occur in the dark and were inhibited by p-dinitrobenzene when photostimulated. In competition experiments, 1-haloadamantane showed more reactivity than 2-haloadamantane. ...

Potency ranking of methemoglobin-forming agents.
French CL, Yaun SS, Baldwin LA, Leonard DA, Zhao XQ, Calabrese EJ. French CL, et al. J Appl Toxicol. 1995 May-Jun;15(3):167-74. doi: 10.1002/jat.2550150306. J Appl Toxicol. 1995. PMID: 7560736
The direct-acting agents, ranked from most to least potent inducers of methemoglobin formation, are: p-dinitrobenzene > o-dinitrobenzene > copper = nitrite > chlorite > chlorate. The ranking from most to least potent inducers of the bioactivated agents a …
