Mandal, Mihirbaran published the artcileOvercoming Time-Dependent Inhibition (TDI) of Cytochrome P450 3A4 (CYP3A4) Resulting from Bioactivation of a Fluoropyrimidine Moiety, Application In Synthesis of 871332-95-5, the publication is Journal of Medicinal Chemistry (2018), 61(23), 10700-10708, database is CAplus and MEDLINE.

Herein the authors describe structure-activity relationship (SAR) and metabolite identification (Met-ID) studies that provided insight into the origin of time-dependent inhibition (TDI) of cytochrome P 450 3A4 (CYP3A4) by compound I. Collectively, these efforts revealed that bioactivation of the fluoropyrimidine moiety of I led to reactive metabolite formation via oxidative defluorination and was responsible for the observed TDI. The authors discovered that substitution at both the 4- and 6-positions of the 5-fluoropyrimidine of I was necessary to ameliorate this TDI as exemplified by compound II.

Amagase, Yoko published the artcilePeroxisome proliferator-activated receptor α agonist-induced histidine decarboxylase gene expression in the rat and mouse liver., Name: Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is The Journal of toxicological sciences (2020), 45(8), 475-492, database is MEDLINE.

By analysis of the data from the Toxicogenomics Database (TG-GATEs), histidine decarboxylase gene (Hdc) was identified as largely and commonly upregulated by three fibrates, clofibrate, fenofibrate, and WY-14,643, which are known to induce hepatocellular hypertrophy and proliferation via stimulation of peroxisome proliferator-activated receptor α (PPARα) in rodents. As histamine has been reported to be involved in the proliferation of liver cells, the present study was conducted to focus on Hdc. Among other genes related to histidine and histamine, the expression of the gene of histamine ammonia lyase (Hal) was exclusively mobilized by the three fibrates. The expression of Hdc, which was usually very low in the liver, was increased with the repeated administration of fibrates, and concomitantly, the constitutive expression of Hal was suppressed. An interpretation is that the formation of urocanic acid from histidine under the normal condition switches to the formation of histamine. The mobilization of gene expression of Hdc and Hal by PPARα agonists could not be reproduced in primary cultured hepatocytes. The Hdc mRNA appeared to be translated to a protein which is processed differently from brain but similarly to gastric mucosa. Surprisingly, the fibrates caused hepatic hypertrophy but no induction of Hdc mRNA at all in mice. These results revealed that the changes in the histidine catabolism by PPARα agonists might be partially, but not directly, involved in the hepatocyte proliferation in rats, and there is a large genetic distance even between rat and mouse.

Shimojima, Atsushi published the artcileSynthesis of Silylated Derivatives of a Layered Polysilicate Kanemite with Mono-, Di-, and Trichloro(alkyl)silanes, Product Details of C9H20Cl2Si, the publication is Chemistry of Materials (2001), 13(10), 3603-3609, database is CAplus.

Interlayer modification of a layered polysilicate kanemite was performed by silylation with mono-, di-, and trichloro(alkyl)silanes. The introduction of silyl groups into the interlayer region was confirmed by XRD, IR, ¹³C NMR, and ²⁹Si NMR. The layered structures of the silylated products were confirmed by swelling behavior upon adsorption of n-alkyl alcs. The amounts of attached alkylsilyl groups varied with the number of functional groups as well as the alkyl chain length in the silylating agents. The products modified with alkyltrichlorosilanes exhibited various interlayer structures due to the different arrangements and/or conformations of the alkyl chains, depending on the chain lengths. The BET surface areas were relatively large (up to ∼480 m² g^-1) when short-chain alkyltrichlorosilanes were used, and decreased substantially to nonporous structures with increasing chain length. In addition to the inherent six-membered rings in the single layered silicate sheets of kanemite, new five- and six-membered rings were formed onto the silicate frameworks when dichloro- and trichlorosilanes were used for silylation. This leads to a new method for constructing novel organosilicate nanomaterials utilizing layered silicates.

The transfer of indole-3-acetic acid (IAA) between both IAA synthesizing compartments of the cell-cytoplasm and chloroplast (influx into chloroplasts from cytoplasm and efflux from chloroplasts into cytoplasm) was educed by employing model systems. From the obtained results the presumption on IAA interaction with proteins IAA-transporters another than pin-formed (PINs) or auxin permease (AUX1) in chloroplast membrane was formulated. The possibility of IAA metabolism occurring in this cell compartment was done. The possible role of IAA and auxin-binding proteins (ABPs) complexes formed in chloroplast was discussed.

Perlikowska, Wieslawa published the artcileLithiation of diethyl trichloromethylphosphonate and the transformations of the α-lithiated derivative, Product Details of C5H10Cl3O3P, the publication is Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1996), 2611-2613, database is CAplus.

The lithiation of di-Et trichloromethylphosphonate below -100° leads to a stable α-lithiated derivative, but at temperatures of ∼-80° the lithiation is accompanied by spontaneous reactions leading to tetra-Et (chloromethylene)bisphosphonate as the exclusive product. Possible mechanisms of the reaction are discussed. Thus, treating Cl₃CPO₃Et₂ with BuLi and anhydrous LiCl in Et₂O at -105° gave 74% Cl₂CHPO₃Et₂, whereas reaction with BuLi in Et₂O at -80° gave 95% ClCH(PO₃Et₂)₂.

Steingruber, H. Sebastian published the artcileConvenient One-Pot Synthesis of 9H-Carbazoles by Microwave Irradiation Employing a Green Palladium-Based Nanocatalyst, HPLC of Formula: 117738-74-6, the publication is Synthesis (2021), 53(21), 4048-4058, database is CAplus.

An efficient palladium-catalyzed tandem reaction for the one-pot synthesis of 9H-carbazoles under microwave irradiation was developed. This approach involves a sequential Buchwald-Hartwig amination and a direct arylation from affordable and inexpensive anilines and 1,2-dihaloarenes. For the development of this purpose, a novel and magnetically recoverable palladium nanocatalyst-supported on a green biochar under ligand-free conditions was used. Compared to other existing palladium-based protocols, the present synthetic methodol. shows a drastic reduction in reaction times and excellent compatibility with different functional groups allowing to obtain a small library of 9H-carbazoles in high yields and with good regioselectivity. This procedure represents the first example in the direct synthesis of carbazoles using a heterogeneous palladium nanocatalyst from com. precursors. To examine the application of this protocol, a direct and scalable synthesis of the bioactive carbazole alkaloid clausenalene from com. available starting materials was described.

An efficient approach has been developed for the construction of quinazolin-4(3H)-ones by the selective anodic dehydrogenative oxidation/cyclization of benzylic chlorides and 2-aminobenzamides [e.g., 2-aminobenzamide + benzyl chloride → 2-phenylquinazolin-4(3H)-one I (80%) employing RVC as anode, Pt as cathode, Bu₄NBF₄ as electrolyte and MeCN as solvent in undivided cell at constant current of 10mA at 80°]. The method features acceptor-free and metal-free dehydrogenation of amines to imines; a subsequent intermol. addition provides the products in moderate to good yields.

Spare, Lawson K. published the artcileA continuous flow protocol to generate, regenerate, load, and recycle chlorotrityl functionalised resins, Product Details of C19H14Cl2, the publication is Reaction Chemistry & Engineering (2019), 4(7), 1309-1317, database is CAplus.

From a screen of chlorinating agent concentration, flow rates, and reagent addition methodologies, a continuous flow protocol to activate, reactivate, and recycle both 2-chlorotrityl chloride functionalised polystyrene and trityl-hydroxy ChemMatrix functionalised resins was established. This protocol significantly reduced resin loading periods. Under batch conditions, previously reported trityl resin chlorination protocols are effected over 1-24 h whereas the continuous flow chlorination procedure was completed within 10 min. Further amino acid residue tethering to the resin was effected within 5 min as opposed to the 2-h loading period typically applied under batch conditions. Moreover, an injection-based continuous-flow methodol. proved effective in maintaining the chiral integrity of Fmoc-His(Trt)-OH, Fmoc-Cys(Trt)-OH, and Fmoc-Ser(t-Bu)-OH, which are susceptible to direct base-induced epimerisation. Further, through incorporating the optimized AcCl resin chlorination protocol into a continuous flow solid-phase peptide construction procedure, a facile and resin recyclable approach to conduct SPPS was established.
