Aldana L Zalazar et al.
Food research international (Ottawa, Ont.), 116, 916-924 (2019-02-06)
Probabilistic microbial modelling using logistic regression was used to predict the growth/no growth (G/NG) interfaces of Zygosaccharomyces bailii in simulated acid sauces as a function of natamycin, xanthan gum (XG) and sodium chloride concentrations. The growth was assessed colorimetrically by
General method for the high yield preparation of 2-(4-X-phenylene) amine-1, 4-naphthoquinones (X= ferrocenyl, OMe, Me, I, Cl, and NO2) from 2-methoxy-1, 4-naphthoquinone and investigation of H+ and Mg2+ catalysts with DFT calculations.
Francisco AI, et al.
Journal of Molecular Structure, 891(1), 228-232 (2008)
Jeremy Yee Hoong Ong et al.
Life sciences, 135, 158-164 (2015-04-22)
The compound 2-methoxy-1,4-naphthoquinone (MNQ) was previously shown to be cytotoxic against several cancer cell lines, but its mode of action is poorly understood. In this study, we aimed to explore the molecular mechanism of MNQ-induced cytotoxicity of A549 lung adenocarcinoma
Scott B Vafai et al.
PloS one, 11(9), e0162686-e0162686 (2016-09-14)
Deficiency of mitochondrial complex I is encountered in both rare and common diseases, but we have limited therapeutic options to treat this lesion to the oxidative phosphorylation system (OXPHOS). Idebenone and menadione are redox-active molecules capable of rescuing OXPHOS activity
K Ishiguro et al.
Journal of natural products, 61(9), 1126-1129 (1998-09-28)
Dinaphthofuran-7,12-dione derivatives named balsaminones A (1) and B (2) were isolated from the pericarp of Impatiens balsamina L. together with the known compound 2-methoxy-1,4-naphthoquinone (3). Their structures were elucidated by spectral techniques. These compounds have significant antipruritic activity.
Nattapon Sritrairat et al.
Journal of oral pathology & medicine : official publication of the International Association of Oral Pathologists and the American Academy of Oral Pathology, 40(1), 90-96 (2010-08-27)
The aim of this study was to determine the antifungal activity of lawsone methyl ether mouthwash (LME) in comparison with chlorhexidine mouthwash (CHX) in vitro and in vivo. For in vitro study, each mouthwash preparation was added into the inoculum
Martin J Mitchell et al.
Archives of insect biochemistry and physiology, 66(1), 45-52 (2007-08-21)
The effects of the natural compound 2-methoxy-1,4-naphthoquinone, isolated from the leaves of Impatiens glandulifera and the synthetic compounds 2-propoxy-1,4-naphthoquinone and 2-isopropoxy-1,4-naphthoquinone on ecdysone 20-monooxygenase (E-20-M) activity were examined in three insect species. Homogenates of wandering stage third instar larvae of

Quinones that exist in ambient particulate matter (PM) are hypothesized to be associated with adverse health effects through the generation of reactive oxygen species (ROS). However, the impacts of the quinones on the inflammatory processes have yet to be clearly
M Chen et al.
Scientific reports, 10(1), 951-951 (2020-01-24)
Olfactory ensheathing cells (OECs) are crucial for promoting the regeneration of the primary olfactory nervous system that occurs throughout life. Transplantation of OECs has emerged as a promising therapy for nervous system injuries, in particular for spinal cord injury repair.
Xiao-Fei Shang et al.
Scientific reports, 8(1), 1609-1609 (2018-01-27)
As important secondary plant metabolites, naphthoquinones exhibit a wide range of biological activities. However, their potential as sustainable alternatives to synthetic acaricides has not been studied. This study for the first time investigates the acaricidal activity of naphthoquinones against Psoroptes
Naomi Mori et al.
Journal of natural medicines, 65(1), 234-236 (2010-10-05)
A screening study using a luciferase assay to identify natural products which inhibit Wnt signaling was carried out. The bioassay-guided fractionation of aerial parts of a plant, Impatiens balsamina, led to the isolation of 2-methoxy-1,4-naphthoquinone (1) as an active compound.
S Rodriguez et al.
Planta medica, 61(4), 362-364 (1995-08-01)
A chemical and biological screening of 25 species of the Gentianaceae family has been undertaken. Both methanolic and dichloromethane extracts of Swertia calycina exhibited a strong antifungal activity against Cladosporium cucumerinum and Candida albicans. The compound responsible for this activity
X Yang et al.
Phytotherapy research : PTR, 15(8), 676-680 (2001-12-18)
By using brine shrimp (Artemia salina) lethality test-guided fractionation, a single bioactive compound (LC(50)=26 ppm) was isolated from the 95% ethanol extract of the dried aerial parts of Impatiens balsamina L. and subsequently identified as 2-methoxy-1,4-naphthoquinone (MNQ). The structure of

2-Methoxy-1,4-naphthoquinone (MeONQ) from Impatiens balsamina L. exhibited strong anti-H. pylori activity in our previous study. In this study, we investigated the cytotoxicity of MeONQ against gastric adenocarcinoma (MKN45 cell line) and propose the relevant mechanisms. MeONQ resulted in serious necrosis
