Shibata, Kentaro published the artcileHomopolymer-block-Alternating Copolymers Composed of Acrylamide Units: Design of Transformable Divinyl Monomers and Sequence-Specific Thermoresponsive Properties, Product Details of C8H5F3O3, the publication is Journal of the American Chemical Society (2022), 144(22), 9959-9970, database is CAplus and MEDLINE.

In this work, we synthesized an acrylamide-based terpolymer that is a block copolymer composed of an AB alternating copolymer and a C homopolymer. The key to the unprecedented achievement is rational design of an acrylate-acrylamide divinyl monomer carrying CF₃-substituted salicylic acid ester bonds (AAm-CF₃) to realize the efficient and selective cyclopolymn. as well as the quant. transformation of the resultant cyclorepeating units. The selectivity in the cyclopolymn. and the pendant transformation ability were evaluated through reactivity ratios of the corresponding model monomers and quant. aminolysis reactions of the model compound The cyclopolymn. via the photoinduced electron transfer-reversible addition-fragmentation chain transfer (PET-RAFT) process with a macrochain-transfer agent and subsequent aminolysis reaction afforded the homopolymer-block-alternating copolymer. The sequence-controlled terpolymer exhibited a very unique thermal response behavior in water that was strikingly different from the corresponding sequence-uncontrolled terpolymers, such as homopolymer-block-statistical copolymers and all statistical terpolymers, despite the fact that the structure cannot be distinguished by ¹H NMR.

Kozlowska, Justyna published the artcileEvaluation of sebostatic activity of Juniperus communis fruit oil and Pelargonium graveolens oil compared to niacinamide, Application In Synthesis of 70445-33-9, the publication is Cosmetics (2017), 4(3), 36/1-36/8, database is CAplus.

As a facial skin condition, oily skin causes cosmetic problems, such as large pores, shiny appearance, and the feeling of greasiness and heaviness. Furthermore, extensive sebum production leads to common skin disorders such as acne vulgaris or seborrheic dermatitis. This study investigated the efficacy of sebum control tonics containing Juniperus communis fruit oil, Pelargonium graveolens oil, or niacinamide. The effects of Juniperus communis fruit oil, Pelargonium graveolens oil, and niacinamide on sebum excretion rates were investigated using Sebumeter. Sebum measurements (SebumeterSM 815, Courage & Khazaka, Köln, Germany) were made on the skin surface in three places by applying the sebumeter probe to the forehead after 10, 60, and 120 min from application of the tonic. The results indicated that the application of the tonic maintained a lower sebum secretion 10 min and 60 min after the application of the cosmetic, compared to those before it. However, a visible sebum-reducing efficacy after 2 h was reported only for tonic containing 0.25% Pelargonium graveolens oil and for the tonic with the addition of 3% niacinamide. After 2 h, the values of sebum measurements were 44 ± 5.13 a.u. and 58 ± 9.07 a.u., resp. Our results show that the tonic with the addition of 0.25% Pelargonium graveolens oil is the most effective in reducing sebum production

Huang, Li published the artcileDifferent photodegradation behavior of 4-tert-octylphenol under UV and VUV irradiation in aqueous solution, Related Products of alcohols-buliding-blocks, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2013), 69-77, database is CAplus.

Comparative study on 4-tert-octylphenol degradation under UV (253.7 nm) and VUV (combined 253.7 nm and 184.9 nm) radiation in aqueous solution was performed in laboratory scale(coating process) in this paper. Excitation light played the key role on 4-tert-octylphenol photodegradation 93.5% 4-tert-Octylphenol was decomposed after 20-min VUV radiation while only 49.5% degradation efficiency was achieved after 4-tert-octylphenol received UV radiation for the same irradiation time. Other factors influencing 4-tert-octylphenol degradation efficiency included solution pH, initial concentration and natural water constituents. Initial 4-tert-octylphenol concentration and pH exhibited different influence pattern on 4-tert-octylphenol degradation under UV and VUV radiation. 4-tert-Octylphenol photodegradation products were discerned by HPLC and GC-MS. 4-tert-octylcatechol was recognized as predominant photoproducts under both UV and VUV radiation. Trace amount of phenol was also detected when 4-tert-octylphenol was subjected to VUV radiation. Degradation of 4-tert-octylphenol upon UV radiation was, therefore, predicted to be initiated by the photoejection of an electron from excited 4-tert-octylphenol, whereas 4-tert-octylphenol photolysis upon VUV radiation may also involve the direct CC bond cleavage from excited 4-tert-octylphenol. No matter the excitation light wavelength, photopolymization process was found to occur at high initial 4-tert-octylphenol concentration Special attention should be paid to the photopolymerization phenomena during practical application of 4-tert-octylphenol photodegradation

Liao, Liping published the artcileSynthesis and biological evaluation of 1,2,4-triazole derivatives as potential neuroprotectant against ischemic brain injury, Recommanded Product: 2-Hydroxy-4-(trifluoromethyl)benzoic acid, the publication is European Journal of Medicinal Chemistry (2020), 112114pp., database is CAplus and MEDLINE.

A series of 1,2,4-triazole derivatives I (R¹ = H, OH; R² = H, F, CF₃, etc.; R³ = H, Me, F, CF₃ ) was synthesized to investigate their neuroprotective effects and mechanisms of action. Some compounds noticeably protected PC12 cells from the cytotoxicity of H₂O₂ or sodium nitroprusside (SNP). Compound I (R¹ = OH; R² = OMe; R³ = H) was the most effective derivative Compound I (R¹ = OH; R² = OMe; R³ = H) chelated Fe (II) iron, scavenged reactive oxygen species (ROS), and restored the mitochondrial membrane potential (MMP). Moreover, it enhanced the activity of the antioxidant defense system by increasing the serum level of superoxide dismutase (SOD) and promoting the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2). Compound I (R¹ = OH; R² = OMe; R³ = H) caused certain improvements in behavior, the cerebral infarction area, and serum levels of biochem. indicators (TNF-α, IL-1β, SOD and MDA) in a rat MCAO model. The LD (LD₅₀) of compound I (R¹ = OH; R² = OMe; R³ = H) in mice receiving i.p. injections was greater than 400 mg/kg. Meanwhile, pharmacokinetic experiments revealed high bioavailability of this compound after both oral and i.v. administration (F = 60.76%, CL = 0.014 mg/kg/h) and a longer half-life (4.26 and 5.11 h after oral and i.v. administration, resp.). Based on these findings, compound I (R¹ = OH; R² = OMe; R³ = H) may be a promising neuroprotectant for the treatment of ischemic stroke.

Cho, Hea-Young published the artcileGastrointestinal and hepatic first-pass effects of triflusal in rats, SDS of cas: 328-90-5, the publication is Yakche Hakhoechi (2001), 31(4), 265-271, database is CAplus.

In order to elucidate the influence of intestinal and hepatic first-pass effect on the pharmacokinetics of triflusal, the biotransformation of triflusal in the gastrointestinal tract and liver was designed. Moreover, we tried to establish an HPLC method applicable for bioassay and available to pharmacokinetics, not only with the simultaneous determination of triflusal and its active metabolite, 2-hydroxy-4-trifluoromethyl benzoic acid (HTB), but also with improving sensitivity. After the administration of triflusal (10 mg/kg) and HTB (10 mg/kg) into femoral vein, portal vein (only triflusal) and oral route (only triflusal), pharmacokinetic parameters were investigated from the plasma concentration-time profiles of triflusal and HTB in rats. An HPLC method was developed for the simultaneous determination of triflusal and HTB in rat plasma, urine and bile. The HPLC anal. was carried out using a C18 column and acetonitrile-methanol-water (25:10:65, volume/volume/v) as the mobile phase and UV detection at 234 nm. Furosemide was used as the internal standard The calibration curves were linear over the concentration range 0.05-5.0 μg/mL for triflusal and 0.2-200.0 μg/mL for HTB with correlation coefficients greater than 0.999 and with intra-day or inter-day coefficients of variation not exceeding 10.0%. This assay procedure was applied to the study of metabolite pharmacokinetics of triflusal and HTB in rats. It was supposed that triflusal was almost metabolized in vivo because urinary and biliary excreted amounts of triflusal could be ignored as it was lower than 1.2 % of the administered dose. According to the gastrointestinal and hepatic biotransformation pathways of triflusal, it was found that triflusal was hydrolyzed by about 5 % in intestine and metabolized by about 53 % in liver, and that the bioavailability of triflusal after oral administration of triflusal was 0.44, and also that the fraction of total elimination rate of triflusal which formed HTB in liver (F_mi, %) was about 98%. These results showed that triflusal was almost metabolized in liver, and the total elimination of triflusal in the body was dependent to the formation rate of HTB from triflusal in liver.

A rapid, selective and sensitive HPLC method was developed and validated for the simultaneous determination of triflusal and its major active metabolite, 2-hydroxy-4-trifluoromethyl HOBz (HTB), in rat and human plasma. HPLC anal. was carried out using a 5-μm particle size, C₁₈-bonded SiO₂ column and MeCN-MeOH-H₂O (25:10:65, volume/volume/v) as the mobile phase and UV detection at 234 nm. Furosemide was used as the internal standard The method involved extraction with an MeCN-CHCl₃ mixture (60:40, volume/volume) and evaporation to dryness with N stream. The chromatograms showed good resolution and sensitivity and no interferences by plasma constituents. The mean absolute recovery for human plasma was 93.5 ± 4.2% for triflusal and 98.5 ± 3.1% for HTB. The lower limits of quantification of triflusal and HTB in human plasma were 20 and 100 ng/mL, resp. The calibration curves in human plasma were linear over the concentration range 0.02-5.0 μg/mL for triflusal and 0.1-200.0 μg/mL for HTB with correlation coefficients >0.999 and with inter- or intra-day coefficients of variation (CV) not exceeding 10.0%. This assay procedure was applied to the study of metabolite pharmacokinetics of triflusal and HTB in rat and human.
