The Chrysopogon zizanioides plant possesses multiple traditional uses, especially in therapeutics, but only a few articles have reported its biol. activity. Hence, the present study was planned to explore the phytochem. constituents, cytotoxic potential, radical scavenging activity, and GC/MS (Gas chromatog. & Mass spectrometry) anal. of the vetiver root extracts The roots extracted with different solvents exhibited more significant phytochem. constituents in polar solvents in comparison to non-polar ones, favoring the extraction of a greater number of components in highly polar solvents. All the extracts were tested for their cytotoxicity using SRB (Sulforhodamine B) assay. They confirmed ethanolic extract as a potent extract with GI50 56±0.5 μg/mL in oral cancer (SCC-29B) along with no cytotoxicity in healthy cells (Vero cells), making it a safer therapeutic option in comparison to standard Adriamycin. This extract was also analyzed for its antioxidant potential by DPPH (1,1-Diphenyl-2-picrylhydrazyl) assay with IC50 value 10.73 μg/mL, which was quite comparable to Ascorbic acid having IC50 value 4.61 μg/mL. The quant. anal. of ethanolic extract exhibited 107 compounds amongst which Khusenic acid, Ascorbic acid, Junipen, gamma-Himachalene, alpha-Guaiene were the majorly occurring compounds that can be explored further for their cytotoxic activity.

In 2022,Energies (Basel, Switzerland) included an article by Wu, Haijun; Shakeel, Usama; Zhang, Quan; Zhang, Kai; Xu, Xia; Xu, Jian. COA of Formula: C4H6O3. The article was titled 《Ethanol-Assisted Hydrothermal Liquefaction of Poplar Using Fe-Co/Al2O3 as Catalyst》. The information in the text is summarized as follows:

Although the conversion of lignocellulosic biomass into bio-oil with high yield/quality through hydrothermal liquefaction (HTL) is promising, it still faces many challenges. In this study, a Fex-Co(1-x)/Al2O3 catalyst was prepared with the coprecipitation method and low-content ethanol was used as the cosolvent for the HTL of poplar. The results showed that the Fex-Co(1-x)/Al2O3 catalyst significantly promoted the yield and energy recovery rate (ERR) of bio-oil compared with the control (10% ethanol content). At 260 °C for 30 min, 60Fe-40Co/Al2O3 had the best catalytic effect, achieving the highest bio-oil yield (67.35%) and ERR (93.07%). As a multifunctional bimetallic catalyst, Fex-Co(1-x)/Al2O3 could not only increase the degree of hydrogenation deoxidization of the product but also promote the diversity of phenolic compounds gained from lignin. The bio-oil obtained from HTL with Fex-Co(1-x)/Al2O3 as catalyst contained lower heterocyclic nitrogen, promoting the transfer of more bio-oil components to substances with lower b.p. The experimental process involved the reaction of 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9COA of Formula: C4H6O3)

3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9) is a 5-membered cyclic ester. It was obtained via tin-conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde.

And the article was published in New Journal of Chemistry in 2020. SDS of cas: 19444-84-9 The author mentioned the following in the article:

As a kind of biomass resource, lignin is the only natural renewable resource that can provide abundant aromatic compounds, which is undoubtedly considered as the best candidate to produce value-added chems. by lignin depolymerization Thus, it is of great significance to develop approaches that are able to accommodate the complex structure of lignin. Herein, an efficient depolymerization method is implemented in methanol using a mesoporous solid superbase KF/γ-Al2O3 catalyst. Research shows that the depolymerization of lignin is not obvious below the critical temperature of methanol, and the conversion of lignin increases significantly above the critical temperature, which can reach 60.6% at 270°C. Phenols and methoxy-substituted monocyclic aromatic compounds are predominant in the liquid products acquired by gas chromatog./mass spectrometry. Furthermore, oligomers were analyzed by time-of-flight mass spectrometry equipped with electrospray ionization. It is found that the mol. mass of the oligomers varied between 200 and 600 Da, the degree of unsaturation is mainly 4 and 8 with 1-2 aromatic rings, and the carbon number is found to be within the range of 15-30. It is speculated that the oligomers are mainly monophenyl or biphenyl compounds containing branched chains.

Latent fingerprints (LFPs) play an important rule for criminal investigations regarding to the identification and connection of an individual to a crime scene. Herein, we report a non-destructive method for LFPs development based on the electropolymerization of pyrrole derivatives modified with water-soluble groups on stainless steel surfaces containing fingerprint residues. The polymers, namely P1, P2, P3 and P4, and a copolymer of 4 with 3,4-ethylenedioxythiophene P(4-co-EDOT) were electrodeposited by oxidation of the monomers in aqueous LiClO4 by applying potentials (E) of 1.25-1.7 V vs. Ag/AgCl or c.d. (j) of 5.0-10 mA cm-2 for 15-240 s. The quality of the developed fingerprint images was verified by SEM, the Griaule Forensic Fingerprint software and the Bandey classification system. It was possible to observe the enhancement of the visual contrast between the surface and the fingerprint residues, providing high quality images of the developed fingerprints.

《Chemical composition and larvicidal activity of flower extracts from Clitoria ternatea against Aedes (diptera: culicidae)》 was written by Ravindran, Darvin R.; Bharathithasan, Madhuri; Ramaiah, Patmani; Rasat, Mohd Sukhairi Mat; Rajendran, Dinesh; Srikumar, Shakila; Ishak, Intan H.; Said, Abd Rahman; Ravi, Rajiv; Amin, Mohamad Faiz Mohd. HPLC of Formula: 19444-84-9 And the article was included in Journal of Chemistry in 2020. The article conveys some information:

Mosquitoes have always been a human health threat; the major global health problems caused by them are malaria, dengue fever, yellow fever, and Zika as well as several other vector-borne outbreaks. The major problems in controlling these vectors borne diseases are related to resistance to eradication measures. Different classes of insecticides used for controlling public health have raised the concern of resistant problems with mosquitoes and environmental pollution caused by the control measures. Thus, a search for alternative natural compounds is necessary for solving the insecticidal resistance problem using pesticides in the larval stage of vector development as well as creating a chem.-free environment for a healthy society. Hence, the major focus of this study is to identify the larvicidal mechanisms, metabolite, antioxidants, and chem. compounds and elucidate their structures from C. ternatea flower and to test their efficacies against early 4th instar larvae of Aedes aegypti and Aedes albopictus. Clitoria ternatea flowers were collected from the garden of the Faculty of Medicine in International Quest University, Ipoh, Perak, and thence used for crude extraction Further on, the metabolite test, antioxidant test, and chromatog. techniques were conducted to identify the chem. composition of extracts and their chem. structures were identified using GCMS-QP2010 Ultra (Shimadzu). Next, the extracts were evaluated against the early 4th instar larvae of Aedes mosquito vectors following the WHO procedures for larval bioassays. The larvicidal activity of Clitoria ternatea flower extracts evidently affected the early 4th instar larvae of Aedes mosquito vectors. The highest larvicidal activity was observed against the early 4th instar larvae of Aedes aegypti with the LC50 and LC95 values of 1056 and 2491 mg/L, resp. Meanwhile, the larvae bioassay test for Aedes albopictus recorded the LC50 and LC95 values of 1425 and 2753 mg/L. Moreover, the results for nontarget organism test on guppy fish, Poecilia reticulata, showed no mortalities with flower extracts at 2500 mg/L, hence posing no toxic effects on fish. In this study, we have found a total of 16 chem. compounds and 6 chem. compounds have been reported to possess direct insecticidal, larvicidal, and pupicidal effects. Six chems. with insecticidal properties were found to be glycerin, 2-hydroxy-gamma-butyrolactone, neophytadiene, n-hexadecanoic acid, cis-vaccenic acid, and octadecanoic acid with a total of 28.7% efficacy. Clitoria ternatea flower extracts also showed different types of phenols such as anthocyanins, flavonoids, and tannins. Our findings showed that the crude extract of Clitoria ternatea flower bioactive mols. is effective and may be developed as biolarvicide for Aedes mosquito vector control. Furthermore, this study also provided a baseline understanding for future research work in the field of applications of Clitoria ternatea flower extracts for their long-term effects on human health such as a food additive, antioxidant, and cosmetic. In addition to this study using 3-Hydroxydihydrofuran-2(3H)-one, there are many other studies that have used 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9HPLC of Formula: 19444-84-9) was used in this study.

The article was titled 《Discovery of a potent β-catenin destabilizer for overcoming the resistance of 5-fluorouracil in colorectal cancer》.Application of 696-59-3 The article contains the following contents:

Wnt/β-catenin signalling is frequently activated in colorectal cancer, in which nuclear β-catenin accumulation contributes to tumor initiation and progression. However, therapeutic agents in clin. use targeting this pathway are lacking. In this report, we describe the synthesis of novel stemona alkaloid analogs and their biol. evaluation, among which compound 3 was identified to efficiently inhibit various CRC cells, including 5-fluorouracil-resistant CRC cells. Mechanistically, this study revealed that compound 3 reduced the protein level of β-catenin without affecting its mRNA level, which suggests an alternative mechanism for β-catenin degradation The expression of downstream proteins, including c-myc, survivin, and cyclin D1, was also significantly inhibited, even in Wnt-activated CRC cells. Briefly, our data highlight the potential of compound 3 as a destabilizer of β-catenin for the treatment of CRC patients.
