Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide and targeted therapeutics exhibit limited success. Polo-like kinase 1 (PLK1), a Ser/Thr kinase, plays a pivotal role in cell-cycle regulation and is considered a promising target in HCC. Here, via structural optimization using both biochem. kinase assays and cellular antiproliferation assays, we discovered a potent and selective PLK1 kinase inhibitor, compound 31. Compound 31 exhibited biochem. activity with IC₅₀ of < 0.508 nM against PLK1 and a KINOMEscan selectivity score (S(1)) of 0.02 at a concentration of 1μM. Furthermore, 31 showed broad antiproliferative activity against a variety of cancer cell lines, with the lowest antiproliferative IC₅₀ (11.1 nM) in the HCC cell line HepG2. A detailed mechanistic study of 31 revealed that inhibition of PLK1 by 31 induces mitotic arrest at the G2/M phase checkpoint, thus leading to cancer cell apoptosis. Moreover, 31 exhibited profound antitumor efficacy in a xenograft mouse model. Collectively, these results establish compound 31 as a good starting point for the development of PLK1 targeted therapeutics for HCC.

Deng, Tianning;Mazumdar, Wrickban;Yoshinaga, Yuki;Patel, Pooja B.;Malo, Dana;Malo, Tala;Wink, Donald J.;Driver, Tom G. research published 《 Rh₂(II)-Catalyzed Intermolecular N-Aryl Aziridination of Olefins using Nonactivated N-Atom Precursors.》, the research content is summarized as follows. The development of the first intermol. Rh₂(II)-catalyzed aziridination of olefins using anilines as nonactivated N atom precursors and an iodine(III) reagent as the stoichiometric oxidant was reported. This reaction required the transfer of an N-aryl nitrene fragment from the iminoiodinane intermediate to a Rh₂(II)-carboxylate catalyst; in the absence of a catalyst only diaryldiazene formation was observed This N-aryl aziridination was general and was successfully realized using as little as 1 equiv of the olefin. Di-, tri- and tetrasubstituted cyclic- or acyclic olefins was employed as substrates and a range of aniline- and heteroarylamine N atom precursors were tolerated. The Rh₂(II)-catalyzed N atom transfer to the olefin was stereospecific, chemo- and diastereoselective to produce the N-aryl aziridine as the only amination product. Because the chem. of nonactivated N-aryl aziridines was underexplored, the reactivity of N-aryl aziridines was explored toward a range of nucleophiles to stereoselectively access privileged 1,2 stereodiads unavailable from epoxides, and removal of the N-2,4-dinitrophenyl group was demonstrated to show that functionalized primary amines was constructed.

Delaunay, Sylvain;Pascual, Gloria;Feng, Bohai;Klann, Kevin;Behm, Mikaela;Hotz-Wagenblatt, Agnes;Richter, Karsten;Zaoui, Karim;Herpel, Esther;Muench, Christian;Dietmann, Sabine;Hess, Jochen;Benitah, Salvador Aznar;Frye, Michaela research published 《 Mitochondrial RNA modifications shape metabolic plasticity in metastasis》, the research content is summarized as follows. Abstract: Aggressive and metastatic cancers show enhanced metabolic plasticity¹, but the precise underlying mechanisms of this remain unclear. Here we show how two NOP2/Sun RNA methyltransferase 3 (NSUN3)-dependent RNA modifications-5-methylcytosine (m⁵C) and its derivative 5-formylcytosine (f⁵C) (references^2-4)-drive the translation of mitochondrial mRNA to power metastasis. Translation of mitochondrially encoded subunits of the oxidative phosphorylation complex depends on the formation of m⁵C at position 34 in mitochondrial tRNA^Met. m⁵C-deficient human oral cancer cells exhibit increased levels of glycolysis and changes in their mitochondrial function that do not affect cell viability or primary tumor growth in vivo; however, metabolic plasticity is severely impaired as mitochondrial m⁵C-deficient tumors do not metastasize efficiently. We discovered that CD36-dependent non-dividing, metastasis-initiating tumor cells require mitochondrial m⁵C to activate invasion and dissemination. Moreover, a mitochondria-driven gene signature in patients with head and neck cancer is predictive for metastasis and disease progression. Finally, we confirm that this metabolic switch that allows the metastasis of tumor cells can be pharmacol. targeted through the inhibition of mitochondrial mRNA translation in vivo. Together, our results reveal that site-specific mitochondrial RNA modifications could be therapeutic targets to combat metastasis.

Category: pyrimidines, 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.
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.

Decker, Ann M.;Brackeen, Marcus F.;Mohammadkhani, Aida;Kormos, Chad M.;Hesk, David;Borgland, Stephanie L.;Blough, Bruce E. research published 《 Identification of a Potent Human Trace Amine-Associated Receptor 1 Antagonist》, the research content is summarized as follows. Human trace amine-associated receptor subtype 1 (hTAAR1) is a G protein-coupled receptor that has therapeutic potential for multiple diseases, including schizophrenia, drug addiction, and Parkinson’s disease (PD). Although several potent agonists have been identified and have shown pos. results in various clin. trials for schizophrenia, the discovery of potent hTAAR1 antagonists remains elusive. Herein, we report the results of structure-activity relationship studies that have led to the discovery of a potent hTAAR1 antagonist (RTI-7470-44, 34). RTI-7470-44 exhibited an IC₅₀ of 8.4 nM in an in vitro cAMP functional assay, a K_i of 0.3 nM in a radioligand binding assay, and showed species selectivity for hTAAR1 over the rat and mouse orthologues. RTI-7470-44 displayed good blood-brain barrier permeability, moderate metabolic stability, and a favorable preliminary off-target profile. Finally, RTI-7470-44 increased the spontaneous firing rate of mouse VTA dopaminergic neurons and blocked the effects of the known TAAR1 agonist RO5166017. Collectively, this work provides a promising hTAAR1 antagonist probe that can be used to study TAAR1 pharmacol. and the potential therapeutic role in hypodopaminergic diseases such as PD.

Dash, Sibananda G.;Thakur, Tejender S. research published 《 Computational Screening of Multicomponent Solid Forms of 2-Aryl-Propionate Class of NSAID, Zaltoprofen, and Their Experimental Validation》, the research content is summarized as follows. A rational coformer screening methodol. was adopted to identify new multicomponent solid preformulations of the 2-aryl propionate class of nonsteroidal anti-inflammatory drugs. The coformer screening was performed using a modified mol. electrostatic potential based site-pair interaction energy computations used in conjunction with the free energy of cocrystal formation calculations to attain better predictability. The computational results were validated against the available exptl. data and used for optimizing the cocrystal screening methodol. for the drug zaltoprofen. A new polymorph and three new cocrystal forms of zaltoprofen were reported in the study, which exhibits up to four times enhancement in the drug solubility than that of the marketed form. We also report one new salt and two new cocrystals of (+)-ibuprofen, a drug from the same 2-aryl propionate family. In hindsight, we propose incorporating secondary heteromeric interactions formed by homo/heterodimer in the calculations of site-pair interaction energy differences for improving the predictability of the mol. electrostatic potential (MESP) based screening. A combined coformer screening strategy utilizing an MESP site-pair interaction energy and the free energy of cocrystal formation calculations helped to develop several novel multicomponent solids of zaltoprofen.

Das, Dharmendra;Bhosle, Akhil A.;Panjikar, Padmini C.;Chatterjee, Amrita;Banerjee, Mainak research published 《 Mn(I)-Catalyzed Mechanochemical C-H Bond Activation: C-2 Selective Alkenylation of Indoles》, the research content is summarized as follows. An efficient mechanochem. method for manganese-catalyzed regioselective C-H bond alkenylation of indoles with alkynes is developed. The present method allows direct C-2 alkenylation of indoles in a mixer mill, employing a com. available low-valent manganese catalyst, MnBr(CO)₅, providing a sustainable route to hydroindolation on alkynes. The developed protocol is highly C-2-selective by the presence of a heteroaromatic N atom as a directing group (namely, pyridyl) and tolerant of structural variations with electron-rich and electron-deficient substituents both in the indoles and in the alkynes. Silica as the grinding media and the presence of a catalytic amount of acid and DIPEA as the base worked favorably to afford a variety of 2-alkenyl indoles in excellent yields at ambient conditions. The terminal alkynes offered better results than internal alkynes in terms of yields and reactivity. The scalability of the reaction was demonstrated by conducting the reactions in the gram scale. A short study indicated that a little tweak in conditions can be useful for double alkenylation to afford carbazole derivatives in moderate yields. A low E-factor along with a clean reaction profile, an easy exptl. setup, the absence of an anhydrous condition, and being devoid of toxic organic solvents proclaims its advantage over the available conventional methods.

The acyl radicals generated in this step were arylated with aryl bromides through a well stablished nickel cross-coupling methodol., leading to a variety of interesting aryl ketones in good yields. Computational calculations also performed to shine light in the HAT step energetics and determined an optimized geometry for the transition state, showing that the hydrogen atom transfer between aldehydes and DABCO was a mildly endergonic, yet sufficiently fast step. The same calculations were performed with quinuclidine, for comparison of both catalysts and the differences are discussed.
