Spratt, Thomas E.; De los Santos, Hannah published the artcile< Reaction of O6-alkylguanine-DNA alkyltransferase with O6-methylguanine analogs: evidence that the oxygen of O6-methylguanine is protonated by the protein to effect methyl transfer>, Application In Synthesis of 84955-32-8, the main research area is alkylguanine DNA alkyltransferase methylguanine analog.

The DNA repair protein O6-alkylguanine-DNA alkyltransferase (AGT) repairs the promutagenic O6-methylguanine lesion by transferring the Me group to a cysteine residue on the protein. A mechanism in which AGT activates the guanyl moiety as a leaving group by protonation of a heteroatom on guanine was probed by reacting AGT with analogs of O6-methylguanine in which the heteroatoms were changed. The initial rates of reaction were measured at various substrate concentrations in 50 mM Hepes, 1 mM EDTA, 1 mM DTT, and 10% glycerol, pH 7.8 at 37). The kinact (h-1) and Kin (mM) were determined for O6-methylguanine (1.66, 1.51) 0.32), 6-methoxypurine (1.07, 10.6), S6-methyl-6-thioguanine (0.63, 1.17), 6-methylthiopurine (no reaction), Se6-methyl-6-selenoguanine (1.76, 10.6), 6-methylselenopurine (2.51, 15.7), O6-methyl-1-deazaguanine (1.71, 14.8), O6-methyl-3-deazaguanine (1.90, 2.54), and O6-methyl-7-deazaguanine (1.97, 2.56). These results indicate that replacement of the nitrogens does not affect the kinact parameter but the Kin is increased upon removal of the exocyclic amino group and the nitrogen at the 1-position. Replacement of the oxygen with sulfur decreases the kinact, and replacement with selenium increases the Kin. The results are consistent with a mechanism in which O6-methylguanine binds to the active site of AGT with hydrogen bonds to the oxygen, the exocyclic amino group, and the nitrogen at the 1-position of the substrate. The Me group is then displaced from the guanine as a proton is transferred to the oxygen, neutralizing the charge on the leaving group.

Application of C5H7N3O, 5-Methylcytosine is a methylated form of the nucleobase cytosine occurring predominantly in cytosine-phosphate-guanine (CpG) islands that are produced by DNA methyltransferases and may regulate gene expression. Like cytosine, the DNA sequence containing 5-methylcytosine (5-mC) is able to be replicated without error and 5-mC can pair with guanine in double stranded DNA. However, DNA sequences containing a high local concentration of 5-mC may be less transcriptionally active than areas with higher ratios of unmodified cytosine.
5-Methylcytosine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Methylcytosine exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 5-methylcytosine is primarily located in the cytoplasm. 5-Methylcytosine can be biosynthesized from cytosine. Outside of the human body, 5-methylcytosine can be found in tea. This makes 5-methylcytosine a potential biomarker for the consumption of this food product.

Hayashi, Toru;Eto, Kei;Kadoya, Yuichi research published 《 Downregulation of ten-eleven translocation-2 triggers epithelial differentiation during organogenesis》, the research content is summarized as follows. DNA methylation of cytosine bases is a major epigenetic modification that regulates gene expression and vertebrate development. The ten-eleven translocation (TET) enzymes oxidize 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), and active DNA demethylation influences gene expression specific to each developmental stage, although recent reports have shown that TET also has a non-catalytic function. In fetal mice, the epithelium in the submandibular gland (SMG) buds as a derivative of the oral cavity at embryonic day 11 (E11) and, by E15, it begins to differentiate into the salivary epithelium, which expresses water-channel aquaporin 5 (AQP5). The functional differentiation of the SMG epithelium can be regulated epigenetically, but how TET enzymes contribute is largely unknown. Here, we used several techniques, including hydroxymethylated DNA immunoprecipitation qPCR and histol. anal., to examine the changes in 5hmC levels and AQP5 and TET expression during SMG development. We found that 5hmC levels and AQP5 expression increased in the E15 SMG epithelium, while TET2 expression in the terminal buds decreased at E15. In agreement with the in vivo observations, Tet2 inhibition ex vivo led to the upregulation of AQP5 expression in terminal buds of the SMG epithelium. These results suggest that the downregulation of TET2 expression at E15 is a critical epigenetic event that establishes the epithelial fate for functional SMGs during development.

Hasan, Mehedi Md;Tsukiyama, Sho;Cho, Jae Youl;Kurata, Hiroyuki;Alam, Ashad Md;Liu, Xiaowen;Manavalan, Balachandran;Deng, Hong-Wen research published 《 Deepm5C: A deep-learning-based hybrid framework for identifying human RNA N5-methylcytosine sites using a stacking strategy》, the research content is summarized as follows. As one of the most prevalent post-transcriptional epigenetic modifications, N5-methylcytosine (m5C) plays an essential role in various cellular processes and disease pathogenesis. Therefore, it is important accurately identify m5C modifications in order to gain a deeper understanding of cellular processes and other possible functional mechanisms. Although a few computational methods have been proposed, their resp. models have been developed using small training datasets. Hence, their practical application is quite limited in genome-wide detection. To overcome the existing limitations, we propose Deepm5C, a bioinformatics method for identifying RNA m5C sites throughout the human genome. To develop Deepm5C, we constructed a novel benchmarking dataset and investigated a mixture of three conventional feature-encoding algorithms and a feature derived from word-embedding approaches. Afterward, four variants of deep-learning classifiers and four commonly used conventional classifiers were employed and trained with the four encodings, ultimately obtaining 32 baseline models. A stacking strategy is effectively utilized by integrating the predicted output of the optimal baseline models and trained with a one-dimensional (1D) convolutional neural network. As a result, the Deepm5C predictor achieved excellent performance during cross-validation with a Matthews correlation coefficient and an accuracy of 0.697 and 0.855, resp. The corresponding metrics during the independent test were 0.691 and 0.852, resp. Overall, Deepm5C achieved a more accurate and stable performance than the baseline models and significantly outperformed the existing predictors, demonstrating the effectiveness of our proposed hybrid framework. Furthermore, Deepm5C is expected to assist community-wide efforts in identifying putative m5Cs and to formulate the novel testable biol. hypothesis.

Iron-based catalysts are a preferred variant of metal catalysts due to the high abundance of iron on earth. Iron carbide has been investigated in recent times as an electrochem. catalyst due to its potential as a great ORR catalyst. Using a unique amine-metal complex anion composite (AMAC) method, iron carbide/nitride nanoparticles (Fe3C and Fe3-xN) were synthesized through varying several reaction parameters. While the synthesis is generally quite robust and can easily afford phase pure Fe3C, it now has been shown that the particle size, morphol., excess carbon, and amount of nitrogen in the resulting nanomaterials can readily be tuned. In addition, it was discovered that Fe2N can be synthesized as an intermediate by stopping the reaction at a lower heating temperature These nanomaterials were tested for their electrochem. activity in oxygen evolution reactions (OER).

Hao, Liping;Ru, Shaoguo;Qin, Jingyu;Wang, Weiwei;Zhang, Jie;Wei, Shuhui;Wang, Jun;Zhang, Xiaona research published 《 Transgenerational effects of parental bisphenol S exposure on zebrafish (Danio rerio) reproduction》, the research content is summarized as follows. Bisphenol S (BPS) is extensively used for production of polycarbonates and other commodities, and is often detected in environment and biota. Parental BPS exposure has been reported to interfere with reproductive development of offspring, but limited information is available on its multigenerational reproductive toxicity. In our present study, zebrafish (Danio rerio) were exposed to BPS (1 and 100μg/L) from 3 hpf to 120 dpf, and the effects on reproduction, sex steroid hormones, DNA methylation levels and gene transcription involved in steroidogenesis and DNA methylation were investigated in unexposed F1-2 offspring. The results showed that 100μg/L BPS exposure increased DNA methylation in F1 testes, and 1μg/L BPS led to DNA methylation in F2 ovaries. The increased DNA methylation levels led to decreased expression of steroidogenic enzymes, including cyp11a, cyp17 and 3βhsd, which might be a main reason for the elevated plasma 17β-estradiol and decreased testosterone levels. In addition, sex ratio indicated a female dominance trend, and reproductive capacity of male fish was severely impaired. Overall, these findings suggest that parental BPS exposure impairs reproductive development of unexposed offspring via DNA methylation and BPS-induced epigenetic modification inheritance has a long-term effect on the fitness and sustainability of fish populations.

Like cytosine, the DNA sequence containing 5-methylcytosine (5-mC) is able to be replicated without error and 5-mC can pair with guanine in double stranded DNA. However, DNA sequences containing a high local concentration of 5-mC may be less transcriptionally active than areas with higher ratios of unmodified cytosine.
5-Methylcytosine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Methylcytosine exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 5-methylcytosine is primarily located in the cytoplasm. 5-Methylcytosine can be biosynthesized from cytosine. Outside of the human body, 5-methylcytosine can be found in tea. This makes 5-methylcytosine a potential biomarker for the consumption of this food product.
5-methylcytosine is a pyrimidine that is a derivative of cytosine, having a methyl group at the 5-position. It has a role as a human metabolite. It is a member of pyrimidines and a methylcytosine. It derives from a cytosine.
5-Methylcytosine is a nucleic acid that is found in the DNA and RNA of the cell. It is an important component of methylation, which is the process by which a methyl group is added to a molecule. This process can lead to cellular transformation, a process that can cause cancer. 5-Methylcytosine has also been shown as a molecular pathogenesis factor in infectious diseases such as HIV and herpes simplex virus type 1. The presence of 5-methylcytosine in nuclear DNA has been detected by analytical techniques such as gas chromatography/mass spectrometry (GC/MS). There are many analytical methods, including GC/MS, that can be used to detect 5-methylcytosine in cellular nuclei., 554-01-8.

Han, Zhengyu;Liu, Gang;Wang, Rui;Dong, Xiu-Qin;Zhang, Xumu research published 《 Highly efficient Ir-catalyzed asymmetric hydrogenation of benzoxazinones and derivatives with a Bronsted acid cocatalyst》, the research content is summarized as follows. The Ir-catalyzed highly efficient asym. hydrogenation of benzoxazinones I (R = H, 7-CH3, 6-Cl, etc.; R1 = H, 4-OCH3, 4-F, etc.) and derivatives II (R2 = H, CH3; R3 = C6H5, C2H5; n = 0, 1) was successfully developed with N-methylated ZhaoPhos as the ligand, which may display a new activation mode with a single anion-binding interaction among the substrate, cocatalyst Bronsted acid and ligand. This synthetic approach afforded a series of chiral dihydrobenzoxazinones III and derivatives IV with excellent results (>99% conversion, 88-96% yields, 91->99% ee, up to 40 500 TON). A key to success is the utilization of a strong Bronsted acid as the cocatalyst, such as hydrochloric acid, to form a possible single anion-binding interaction with the substrate and catalyst, which greatly contributed to the improvement of reactivity and enantioselectivity. Importantly, a creative and efficient synthetic route was developed to construct the important intermediate for the potential IgE/IgG receptor modulator through our catalytic methodol. system.
