Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 533-73-3, formula is C6H6O3, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Safety of Benzene-1,2,4-triol
Pantwalawalkar, Jidnyasa;More, Harinath;Bhange, Deu;Patil, Udaykumar;Jadhav, Namdeo research published 《 Novel curcumin ascorbic acid cocrystal for improved solubility》, the research content is summarized as follows. The present investigation aims to develop novel curcumin-ascorbic acid cocrystal for enhancing the solubility, stability, and complementary biol. activities for curcumin. Based on in silico approach to screen ascorbic acid as a coformer for curcumin, cocrystals were prepared by the solvent evaporation method, and further evaluated for saturation solubility, cocrystal propensity, physicochem. interactions (FTIR and DSC), XRD, drug dissolution, etc. In silico findings confirmed the suitability (H_ex, G_mix) of ascorbic acid for the cocrystn. of curcumin. The DSC and XRD data of the solvent evaporated curcumin-ascorbic acid mixture confirmed the formation of cocrystal, eutectic, and binary mixture with an excess of coformer. The binary phase diagram implied 0.5 to the 0.65-mol fraction of curcumin, essential for cocrystn. with ascorbic acid. The novel curcumin ascorbic acid cocrystals revealed extraordinary improvement in aqueous solubility of curcumin, especially, 576 fold in distilled water, 10 fold in the buffer pH 1.2, and 9 fold in the buffer pH 6.8. The curcumin-ascorbic acid cocrystal system exhibited a superior dissolution profile compared to neat curcumin. Thus, ascorbic acid has enunciated its role as a coformer for curcumin in cocrystal formation, which has been complemented by predicted complementary biol. activities, and stability (acidic milieu).
Safety of Benzene-1,2,4-triol, Benzene-1, 2, 4-triol, also known as hydroxyhydroquinone or 1, 2, 4-benzenetriol, belongs to the class of organic compounds known as hydroxyquinols and derivatives. Hydroxyquinols and derivatives are compounds containing a 1, 2, 4-trihydroxybenzene moiety. Benzene-1, 2, 4-triol is soluble (in water) and a very weakly acidic compound (based on its pKa). Outside of the human body, benzene-1, 2, 4-triol can be found in tea. This makes benzene-1, 2, 4-triol a potential biomarker for the consumption of this food product.
Benzene-1,2,4-triol is a benzenetriol carrying hydroxy groups at positions 1, 2 and 4. It has a role as a mouse metabolite.
1,2,4-Benzenetriol is a metabolite of benzene.
1,2,4-Benzenetriol is an intermediary metabolite of benzene that is present in roasted coffee beans. It is mutagenic and it causes cleaving of DNA single strands by the generation of reactive oxygen species.
1,2,4-Benzenetriol is a reactive molecule that has been shown to have hydrogen bonding interactions with copper chloride. It has been proposed as an inhibitor of methyltransferase, which is involved in the synthesis of methionine. Studies have shown that 1,2,4-Benzenetriol can also inhibit iron homeostasis and transfer reactions. The x-ray diffraction data for this compound shows that it forms a complex with the hydroxyl group. This complex is stabilized by hydrogen bonding interactions with the hydroxylic proton of the 1,2,4-benzenetriol molecule. 1,2,4-Benzenetriol has been shown to be toxic to HL-60 cells and K562 cells at concentrations greater than 5 mM. It has also been found to be effective against chlorogenic acids and other compounds in energy metabolism studies at concentrations between 0.5 and 2 mM., 533-73-3.
