The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《The beneficial effects of edible kynurenic acid from marine horseshoe crab (Tachypleus tridentatus) on obesity, hyperlipidemia, and gut microbiota in high-fat diet-fed mice》. Authors are Li, Jian; Zhang, Yaqi; Yang, Shen; Lu, Zhenhua; Li, Guiling; Wu, Shangyi; Wu, Da-Ren; Liu, Jingwen; Zhou, Bo; Wang, Hui-Min David; Huang, Shi-Ying.The article about the compound:4-Hydroxyquinoline-2-carboxylic Acidcas:492-27-3,SMILESS:O=C(C1=NC2=CC=CC=C2C(O)=C1)O).Reference of 4-Hydroxyquinoline-2-carboxylic Acid. Through the article, more information about this compound (cas:492-27-3) is conveyed.

The marine horseshoe crab (Tachypleus tridentatus) has been considered as food and traditional medicine for many years. Kynurenic acid (KA) was isolated from horseshoe crab in this study for the first time in the world. A previous study in 2018 reported that i.p. administration of KA prevented high-fat diet- (HFD-) induced body weight gain. Now, we investigated the effects of intragastric gavage of KA on HFD mice and found that KA (5 mg/kg/day) inhibited both the body weight gain and the increase of average daily energy intake. KA reduced serum triglyceride and increased serum high-d. lipoprotein cholesterol. KA inhibited HFD-induced the increases of serum low-d. lipoprotein cholesterol, coronary artery risk index, and atherosclerosis index. KA also suppressed HFD-induced the increase of the ratio of Firmicutes to Bacteroidetes (two dominant gut microbial phyla). KA partially reversed HFD-induced the changes in the composition of gut microbial genera. These overall effects of KA on HFD mice were similar to that of simvastatin (pos. control). But the effects of 1.25 mg/kg/day KA on HFD-caused hyperlipidemia were similar to the effects of 5 mg/kg/day simvastatin. The pattern of relative abundance in 40 key genera of gut microbiota from KA group was closer to that from the normal group than that from the simvastatin group. In addition, our in vitro results showed the potential antioxidant activity of KA, which suggests that the improvement effects of KA on HFD mice may be partially associated with antioxidant activity of KA. Our findings demonstrate the potential role of KA as a functional food ingredient for the treatment of obesity and hyperlipidemia as well as the modulation of gut microbiota.

We investigated the renoprotective effects of imidapril hydrochloride ((-)-(4 S)-3-[(2 S)-2-[[(1 S)-1-ethoxycarbonyl-3-phenylpropyl] amino] propionyl]-1-methyl-2-oxoimidazolidine-4-carboxylic acid hydrochloride, imidapril), an angiotensin-converting enzyme inhibitor, in a diabetic animal model. We used BKS.Cg-+Leprdb/+Leprdb (db/db) mice, a genetic animal model of obese type 2 diabetes. Diabetic db/db mice suffered from glomerular hyperfiltration, albuminuria and hypoalbuminemia. Oral administration of 5 mg/kg/day of imidapril for 3 wk suppressed renal hyperfiltration, reduced albuminuria and normalized hypoalbuminemia. Imidapril did not influence body weights, blood pressure or blood glucose concentrations in db/db mice. Urinary excretion of heparan sulfate (HS) in non-treated 11-wk-old db/db mice was significantly lower than that in age-matched non-diabetic db/+m mice. HS is a component of HS proteoglycans, which are present in glomerular basement membranes and glycocalyx of cell surfaces. Reduced urinary HS excretion indicated glomerular HS loss in db/db mice. Imidapril increased urinary excretion of HS to concentrations observed in db/+m mice, indicating that imidapril prevented the loss of renal HS. These results suggest that imidapril ameliorates renal hyperfiltration and loss of renal contents of HS. Improvement of filtration function and maintenance of HS, which is an important structural component of glomeruli, may contribute to renoprotective effects of imidapril.

In general OLED research, rotational and angle tilted deposition are widely used to maintain uniformity. However, there have been few reports on the effects of this deposition method on film characteristics. We analyzed these effects and found that the film d. and its refractive index showed remarkable changes as a function of substrate rotational speed during tilted deposition. The EL characteristics of the transport layer of fluorescent OLEDs were also significantly affected. We derived the OLED optimal thickness and refractive index from our calculations

High entropy alloy nanoparticles (HEA-NPs) are reported to have superior performance in catalysis, energy storage, and conversion due to the broad range of elements that can be incorporated in these materials, enabling tunable activity, excellent thermal and chem. stability, and a synergistic catalytic effect. However, scaling the manufacturing of HEA-NPs with uniform particle size and homogeneous elemental distribution efficiently is still a challenge due to the required critical synthetic conditions where high temperature is typically involved. In this work, we demonstrate an efficient and scalable microwave heating method using carbon-based materials as substrates to fabricate HEA-NPs with uniform particle size. Due to the abundant functional group defects that can absorb microwave efficiently, reduced graphene oxide is employed as a model substrate to produce an average temperature reaching as high as ~1850 K within seconds. As a proof-of-concept, we utilize this rapid, high-temperature heating process to synthesize PtPdFeCoNi HEA-NPs, which exhibit an average particle size of ~12 nm and uniform elemental mixing resulting from decomposition nearly at the same time and liquid metal solidification without diffusion. Various carbon-based materials can also be employed as substrates, including one-dimensional carbon nanofibers and three-dimensional carbonized wood, which can achieve temperatures of >1400 K. This facile and efficient microwave heating method is also compatible with the roll-to-roll process, providing a feasible route for scalable HEA-NPs manufacturing

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Excited states of the phthalimide chromophore and their exciton couplings: a tool for stereochemical assignments, published in 1998-11-25, which mentions a compound: 148857-42-5, mainly applied to phthalimide chromophore exciton coupling stereochem assignment, Safety of (S)-2-(3-Chloro-2-hydroxypropyl)isoindoline-1,3-dione.

Electronically excited states of the phthalimide chromophore were studied by linear dichroism (LD) of samples partially oriented in poly(vinyl alc.) films, magnetic CD (MCD), and CD spectroscopy. On the basis of the LD measurements, the low-energy tail (340-320 nm) of the 1st absorption band is assigned to an out-of-plane polarized n→π* transition (I). At higher energy, the electronic spectrum is resolved into contributions from 5 π→π* transitions: II (300 nm, long-axis polarized), III (275 nm, short-axis polarized), IV (235 nm, short-axis polarized), V (220 nm, long-axis polarized), and VI (∼210 nm, short-axis polarized). The results from semiempirical (INDO/S-CI) and ab initio (CIS/6-31+G(d)) MO calculations compare well with the proposed assignments of the excited states. Degenerate exciton interaction between elec.-dipole-allowed transitions of 2 phthalimide chromophores is observed in the electronic absorption spectra of the achiral bis-phthalimides I (n = 0-2) and in the CD spectrum of the chiral bis-phthalimide II (X = phthalimido). For the latter compound, the solid-state geometry was determined by x-ray diffraction. Good agreement between exptl. and computed CD spectra confirms that the coupled-oscillator exciton model provides the basis for a reliable nonempirical method for the assignment of absolute configuration for this class of compounds Nondegenerate exciton coupling between phthalimide and benzoate or Ph chromophores is borne out in the CD spectra of homochiral mols. II (X = OBz, Ph) with a rigid cyclohexane skeleton. Finally, the exciton-coupling method is used to make stereochem. assignments for the acyclic, conformationally flexible derivatives RCHMeCH2X (R = phthalimido throughout this abstract; X = R, OBz), RCH2CHMeOBz and RCH2CH(OBz)CH2Cl.
