On June 30, 1995, Cash, Gordon G. published an article.Safety of 3-Nitro-4-chlorobenzenesulfonamide The title of the article was Prediction of inhibitory potencies of arenesulfonamides toward carbonic anhydrase using easily calculated molecular connectivity indices. And the article contained the following:

Previous literature reports described the correlation of arenesulfonamide inhibitory potency toward carbonic anhydrase with a quantum mech. descriptor, namely, the total charge on the sulfonamide oxygens, and an indicator variable. The present paper attempts to correlate the same inhibitory potency data with the much more easily calculated mol. connectivity indexes (MCIs) for the same set of compounds A good (r = 0.91) two-variable correlation was found for an subset, from which compounds with a certain structural characteristic had been excluded. This result is consistent with many previous reports that MCIs do well in predicting relative biol. activities of a homologous series of compounds but less well for groups of compounds that differ at several sites. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Safety of 3-Nitro-4-chlorobenzenesulfonamide

Siddique, Nadeem Ahmad; Mujeeb, Mohd.; Najmi, Abul Kalam; Aftab, A.; Aslam, Junaid published an article in 2011, the title of the article was Free radical scavenging and hepatoprotective activity of Aegle marmelos (Linn.) corr leaves against carbon tetrachloride.Related Products of 456-12-2 And the article contains the following content:

Aegle marmelos L. belongs to the family Rutaceae; an important medicinal plant being used in the folk therapy. It is the most useful medicinal plant of India. Its medicinal properties have been described in the ancient medical literature. All parts of the tree (stem, bark, root, leaves and fruit at all stages of maturity) have medicinal virtues and have been used as medicine for a long time. A number of chem. constituents have been isolated from various plant parts including alkaloids, coumarin and steroids. The leaves contain skimianinc, sterol and aegelin. In the present investigation antioxidant and hepatoprotective activity of the methanolic extract of A. marmelos leaves (MEAML) was examined on carbon tetrachloride (CCl4) intoxicated rats. MEAML hold considerable amount of phenolic (9.8367 ± 0.0235 mg/kg) and flavonoid (8.248 ± 0.029 mg/kg) contents, which confirmed the antioxidant property of the leaves. The MEAML with different doses (50, 100, 200 mg/kg body weight) and standard silymarin (40 mg/kg body weight) were orally administered to CCl4 treated rats and the effect was studied on serum enzymes [(aspartate transaminase (AST), alanine transaminase (ALT), alk. phosphatase (ALP), and bilurubin, protein, albumin, thiobarbutiric acid (TBARS), reduced glutathione (GSH)]. In addition, in-vitro antioxidant activity of MEAML was also evaluated using 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical. We noticed a significant hepatoprotective activity of MEAML on CCl4 intoxicated rats which support folkloric utilization of A. marmelos, and it was further confirmed by the histol. investigation. The findings of the present investigation revealed that the MEAML possess significant hepatoprotective activity by suppressing CCl4 induced cellular oxidative stress. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Related Products of 456-12-2

Mala, S. Kumar; Priya, Antony P.; Bincy, Baby; Nazeem, P. A. published an article in 2015, the title of the article was Bioactive compounds to target anti apoptotic proteins- Bcl 2 and Bcl XL an in silico approach.Formula: C18H19NO3 And the article contains the following content:

Phytochems. from several herbaceous and spice plants have been reported to have defense properties against various diseases. Potential of some of such plants like Allium sativum, Curcuma longa, Boerhaavia diffusa, Pterocarpus marsupium and Zingiber officinale in cancer therapy has already been proved. The state of Kerala in southern India hosts large number of medicinal herbs and is also referred as a hotspot of biodiversity. The current study aimed at computational screening of potent lead mols. from ten selected medicinal plants and five spices widely used in Kerala, which are rich in biol. diversity and its traditional values. Even though, the anticancer properties of all these plants and spices were reported, their mode of action and target mols. is not well explained. Hence, the interaction of these compounds with anti-apoptotic proteins Bcl-2 and Bcl-XL are studied and discussed in this paper. The -CDOCKER energy, -CDOCKER interaction energy, Hydrogen bonds, binding energy, and complex energy were predicted through mol. docking studies. Based on binding energy and CDOCKER scores, the active components of Pterocarpus marsupium, Aegle marmelos, Pseudarthira viscida, Allium sativum, Phyllanthus amarus, Boerhaavia diffusa and Catharanthus roseus were observed to have strong interaction with both the proteins. Pharmacokinetic anal. such as absorption, solubility, BBB penetration, and toxicity were also performed for these compounds Comparative docking anal. showed higher interaction than the known inhibitors such as Obatoclax and apogossypolone. Finally, the lead mols. were screened based on their hepatotoxicity. Ten of them passed the anal. and some with high binding energy failed to do so. The lead mols. identified and their probable functional groups could be further reported to transform them as potential anti-apoptotic inhibitors. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Formula: C18H19NO3

On June 1, 2011, Quirico, Eric; Bourot-Denise, Michele; Robin, Christophe; Montagnac, Gilles; Beck, Pierre published an article.Safety of 3-Nitro-4-chlorobenzenesulfonamide The title of the article was A reappraisal of the metamorphic history of EH3 and EL3 enstatite chondrites. And the article contained the following:

The thermal history of a series of EH3 and EL3 chondrites has been investigated by studying the degree of structural order of the organic matter (OM) located and characterized in matrix areas by Raman micro-spectroscopy. By comparison with unequilibrated ordinary chondrites (UOCs) and CO and CV carbonaceous chondrites, the following petrol. types have been assigned to various E chondrites: Sahara 97096 and Allan Hills 84206: 3.1-3.4; Allan Hills 85170 and Parsa: 3.5; Allan Hills 85119: 3.7; Qingzhen, MacAlpine Hills 88136 and MacAlpine Hills 88184: 3.6-3.7. The petrol. type of Qingzhen is consistent with the abundance of the P3 noble gas component, a sensitive tracer of the grade of thermal metamorphism. The petrol. types are qual. consistent with the abundance of fine-grained matrix for the whole series. No significant effects of shock processes on the structure of OM were observed However such processes certainly compete with thermal metamorphism and the possibility of an effect cannot be fully discarded, in particular in the less metamorphosed objects. The OM precursors accreted by the EH3 and EL3 parent bodies appear to be fairly similar to those of UOCs and CO and CV carbonaceous chondrites. Raman data however show some slight structural differences that could be partly accounted for by shock processes. The metamorphic history of EH3 and EL3 chondrites has often been described as complex, in particular regarding the combined action of shock and thermal metamorphism. Because OM maturity is mostly controlled by the temperature of peak metamorphism, it is possible to distinguish between the contributions of long duration thermal processes and that of shock processes. Comparison of the petrol. types with the closure temperatures previously derived from opaque mineral assemblages has revealed that the thermal history of EH3 and EL3 chondrites is consistent with a simple asteroidal onion shell model. Thermal metamorphism in enstatite chondrites appears to be fairly similar to that which takes place in other chondrite classes. The complex features recorded by mineralogy and petrol. and widely reported in the literature appear to be mostly controlled by shock processes.

On December 15, 2016, Piani, Laurette; Marrocchi, Yves; Libourel, Guy; Tissandier, Laurent published an article.Application In Synthesis of 3-Nitro-4-chlorobenzenesulfonamide The title of the article was Magmatic sulfides in the porphyritic chondrules of EH enstatite chondrites. And the article contained the following:

The nature and distribution of sulfides within 17 porphyritic chondrules of the Sahara 97096 EH3 enstatite chondrite have been studied by backscattered electron microscopy and electron microprobe in order to investigate the role of gas-melt interactions in the chondrule sulfide formation. Troilite (FeS) is systematically present and is the most abundant sulfide within the EH3 chondrite chondrules. It is found as either poikilitically enclosed in low-Ca pyroxenes or scattered within the glassy mesostasis. Oldhamite (CaS) and niningerite [(Mg,Fe,Mn)S] are present in ≈60% of the chondrules studied. While oldhamite is preferentially present in the mesostasis, niningerite associated with silica is generally observed in contact with troilite and low-Ca pyroxene. The Sahara 97096 chondrule mesostases contain high abundances of alkali and volatile elements (average Na2O = 8.7 weight%, K2O = 0.8 weight%, Cl = 7100 ppm and S = 3700 ppm) as well as silica (average SiO2 = 62.8 weight%). The data suggests that most of the sulfides found in EH3 chondrite chondrules are magmatic minerals that formed after the dissolution of S from a volatile-rich gaseous environment into the molten chondrules. Troilite formation occurred via sulfur solubility within Fe-poor chondrule melts followed by sulfide saturation, which causes an immiscible iron sulfide liquid to sep. from the silicate melt. The FeS saturation started at the same time as or prior to the crystallization of low-Ca pyroxene during the high temperature chondrule forming event(s). Protracted gas-melt interactions under high partial pressures of S and SiO led to the formation of niningerite-silica associations via destabilization of the previously formed FeS and low-Ca pyroxene. The authors also proposed that formation of the oldhamite occurred via the sulfide saturation of Fe-poor chondrule melts at moderate S concentration due to the high d.p. and the high Na-content of the chondrule melts, which allowed the activity of CaO in the melt to be enhanced. Gas-melt interactions thus appear to be a key process that may control the mineralogy of chondrules in the different classes of chondrite. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Application In Synthesis of 3-Nitro-4-chlorobenzenesulfonamide

On March 31, 2012, Le Guillou, Corentin; Rouzaud, Jean-Noel; Bonal, Lydie; Quirico, Eric; Derenne, Sylvie; Remusat, Laurent published an article.Recommanded Product: 97-09-6 The title of the article was High resolution TEM of chondritic carbonaceous matter: metamorphic evolution and heterogeneity. And the article contained the following:

The insoluble carbonaceous matter from 12 chondrites (CI, CM, CO, CV, EH, and UOC), was characterized by high resolution transmission electron microscopy (HRTEM). Besides ubiquitous nanoglobules, the insoluble organic matter from petrol. type 1 and 2 chondrites and Semarkona (LL 3.0) is composed of a highly disordered polyaromatic component. No structural differences were observed between these IOMs, in agreement with the limited thermal metamorphism they all experienced. In chondrites of petrol. type >3.0, the evolution of the IOM is controlled by the extent of thermal metamorphism. The polyaromatic layers, shorter than 1 nm in petrol. type ≤3.0 chondrites, grow up to sizes between 5 and 10 nm in petrol. type >3.6 chondrites, contributing to the increase of the degree of structural order. In addition, we find rare, but ubiquitous onion-like carbons, which may be the product of nanodiamond graphitization. The insoluble carbonaceous matter of the enstatite chondrite Sahara 97096 (EH 3) is different from the other meteorites studied here. It is more heterogeneous and displays a high abundance of graphitized particles. This may be the result of a mixture between (1) the disordered carbon located in the matrix, and (2) catalytic graphitized phases associated with metal, potentially originating from partial melting events. The structural and nanostructural evolution are similar in all IOMs. This suggests that the structure of the accreted precursors and the parent body conditions of their secondary thermal modifications (temperature, duration, and pressure) were similar. The limited degree of organization of the most metamorphosed IOMs compared with terrestrial rocks submitted to similar temperature suggests that the conditions are not favorable to graphitization processes, due to the chem. nature of the precursor or the lack of confinement pressure.

On March 1, 2009, Rubin, Alan E.; Huber, Heinz; Wasson, John T. published an article.Product Details of 97-09-6 The title of the article was Possible impact-induced refractory-lithophile fractionations in EL chondrites. And the article contained the following:

Literature data show that refractory-lithophile elements in most chondrite groups are unfractionated relative to CI chondrites; the principal exception is the EL-chondrite group whose observed falls (all of which are type 6) are depleted in Ca and light REE. In contrast, literature data and our new INAA data on EL3 PCA 91020, EL3 MAC 88136 and EL4 Grein 002 show that some replicates of these samples have nearly flat REE patterns (unlike those of EL6 chondrites); other replicates exhibit fractionated REE patterns similar to those of EL6 chondrites. Petrog. examination shows that many EL6 (and some EL3 and EL4) chondrites are impact-melt breccias or contain impact-melted portions. We suggest that the same impact processes that formed these breccias and produced melt are responsible for the observed bulk compositional fractionations in refractory-lithophile elements, i.e., EL6 chondrites were produced from initially unequilibrated EL3 material. When large amounts of impact heat were deposited, plagioclase and/or oldhamite (CaS) (the major REE carriers in enstatite chondrites) may have been melted and then transported appreciable (>10 cm) distances. EL6 chondrites represent the residuum that is depleted in REE (particularly in LREE) and Ca. Unlike the case for EL chondrites, our new INAA data on ALH 84170, EET 87746 and SAH 97096 (all EH3) show some scatter but are consistent with the EH group having uniform refractory-lithophile abundances.

And the article contained the following:

The insoluble organic matter (IOM) of an unequilibrated enstatite chondrite Sahara (SAH) 97096 has been investigated using a battery of anal. techniques. As the enstatite chondrites are thought to have formed in a reduced environment at higher temperatures than carbonaceous chondrites, they constitute an interesting comparative material to test the heterogeneities of the IOM in the solar system and to constrain the processes that could affect IOM during solar system evolution. The SAH 97096 IOM is found in situ: as submicrometer grains in the network of fine-grained matrix occurring mostly around chondrules and as inclusions in metallic nodules, where the carbonaceous matter appears to be more graphitized. IOM in these two settings has very similar δ15N and δ13C; this supports the idea that graphitized inclusions in metal could be formed by metal catalytic graphitization of matrix IOM. A detailed comparison between the IOM extracted from a fresh part and a terrestrially weathered part of SAH 97096 shows the similarity between both IOM samples in spite of the high degree of mineral alteration in the latter. The isolated IOM exhibits a heterogeneous polyaromatic macromol. structure, sometimes highly graphitized, without any detectable free radicals and deuterium-heterogeneity and having mean H- and N-isotopic compositions in the range of values observed for carbonaceous chondrites. It contains some submicrometer-sized areas highly enriched in 15N (δ15N up to 1600‰). These observations reinforce the idea that the IOM found in carbonaceous chondrites is a common component widespread in the solar system. Most of the features of SAH 97096 IOM could be explained by the thermal modification of this main component. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Recommanded Product: 3-Nitro-4-chlorobenzenesulfonamide
