Synthesis, structural assignments and antiinfective activities of 3-O-benzyl-carvotacetone and 3-hydroxy-2-isopropyl-5-methyl-p-benzoquinone.
Masila VM, Ndakala AJ, Byamukama R, Midiwo JO, Kamau RW, Wang M, Kumarihamy M, Zhao J, Heydreich M, Muhammad I. Masila VM, et al. Nat Prod Res. 2021 Nov;35(21):3599-3607. doi: 10.1080/14786419.2020.1716346. Epub 2020 Jan 30. Nat Prod Res. 2021. PMID: 31997645
In an attempt to synthesize carvotacetone analogues, new 3-O-benzyl-carvotacetone (10) and previously reported 3-hydroxy-2-isopropyl-5-methyl-p-benzoquinone (11) were synthesized from piperitone (7). In this work, we describe the synthesis of 10 and other ana …

Characterization of the 3-methyl-4-nitrophenol degradation pathway and genes of Pseudomonas sp. strain TSN1.
Takeo M, Yamamoto K, Sonoyama M, Miyanaga K, Kanbara N, Honda K, Kato DI, Negoro S. Takeo M, et al. J Biosci Bioeng. 2018 Sep;126(3):355-362. doi: 10.1016/j.jbiosc.2018.04.001. Epub 2018 Apr 24. J Biosci Bioeng. 2018. PMID: 29699943
The purified mnpA2 gene product could efficiently reduce methyl p-benzoquinone (MBQ) into MHQ. These results suggest that strain TSN1 degrades 3M4NP via MBQ, MHQ, and 2H5MBQ in combination with mnpA1A2 and mnpCB, existing at different loci on the genome....

Synthesis of some NH- and NH,S- substituted 1,4-quinones.
Kaçmaz A. Kaçmaz A. Turk J Chem. 2021 Apr 28;45(2):475-484. doi: 10.3906/kim-2011-3. eCollection 2021. Turk J Chem. 2021. PMID: 34104058 Free PMC article.
A series of NH-substituted-1,4-quinones, possessing one, two, three or not chlorine, were synthesized by the reaction between different quinones (p-chloranil (1), p-toluquinone (2), or 2,3-dichloro-1,4-naphthoquinone (3)) and (-)-cis-myrtanylamine (5) via nucleophil …

Observation and ultrafast dynamics of a nonvalence correlation-bound state of an anion.
Bull JN, Verlet JRR. Bull JN, et al. Sci Adv. 2017 May 19;3(5):e1603106. doi: 10.1126/sciadv.1603106. eCollection 2017 May. Sci Adv. 2017. PMID: 28560345 Free PMC article.
We present a direct spectroscopic observation of this nonvalence correlation-bound state (CBS) in the para-toluquinone trimer cluster anion. Time-resolved photoelectron velocity map imaging shows that photodetachment of the CBS produces a narrow and highly anisotropic phot …
