Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Monodisperse micelles composed of poly(ethylene glycol) attached surfactants: platonic nature in a macromolecular aggregate. Author is Lee, Ji Ha; Matsumoto, Hayata; Fujii, Shota; Takahashi, Rintaro; Sakurai, Kazuo.

Among the many studies on micelles, dating back more than 100 years, we first found a series of monodisperse micelles: spherical micelles made from calix[4]arene surfactants exhibited monodispersity in aggregation number (Nagg) with values of 4, 6, 8, 12, and 20. We named these Platonic micelles because these values coincided with the face numbers of the Platonic solids. The preferred Nagg values were explained in relation to the math. Tammes problem: how to obtain the best coverage of a sphere surface with multiple identical circles. In this paper, we synthesized poly(ethylene glycol)-attached surfactants and carried out small-angle X-ray scattering (SAXS) and anal. ultracentrifugation (AUC) to determine the Nagg. We found that these polymeric surfactants also formed monodispersed micelles and Nagg discontinuously increased from 20 to 24, and then 32 with increasing the alkyl carbon numbers from 9 to 11 continuously. The determined Nagg was greater than 20 and the Platonic solid numbers We assumed that the preferred Nagg values could be explained in relation to the Tammes problem as well.

A review. Cyclin-dependent kinase (CDK) 7 has a unique functional repertoire by virtue of its dual role in transcription and cell cycle progression. Whereas CDK7 is ubiquitously expressed in various types of cancer, its downregulation leads to reduced cell proliferation. Importantly, it is now agreed that targeting transcription selectively limits the synthesis of mRNAs involved in tumor growth without causing an outage of transcription of housekeeping genes. Thus, CDK7 has been considered as a viable therapeutic target in cancer. Indeed, the development of CDK7 inhibitors has gained huge momentum with two mols., CT7001 and SY-1365, currently under clin. development. Herein, we discuss the latest understanding of the role of CDK7 in cancer cells and provide an overview of the pharmacophores of CDK7 inhibitors, their efficacy in various cancer models, and their clin. development.

A novel series of small-mol. inhibitors has been developed to target the double mutant form of the epidermal growth factor receptor (EGFR) tyrosine kinase, which is resistant to treatment with gefitinib and erlotinib. Our reported compounds also show selectivity over wild-type EGFR. Guided by mol. modeling, this series was evolved to target a cysteine residue in the ATP binding site via covalent bond formation and demonstrates high levels of activity in cellular models of the double mutant form of EGFR. In addition, these compounds show significant activity against the activating mutations, which gefitinib and erlotinib target and inhibition of which gives rise to their observed clin. efficacy. A glutathione (GSH)-based assay was used to measure thiol reactivity toward the electrophilic functionality of the inhibitor series, enabling both the identification of a suitable reactivity window for their potency and the development of a reactivity quant. structure-property relationship (QSPR) to support design.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1452-77-3, is researched, SMILESS is O=C(N)C1=NC=CC=C1, Molecular C6H6N2OJournal, Article, Acta Crystallographica, Section E: Crystallographic Communications called Structure and NMR properties of the dinuclear complex di-μ-azido-κ4N1:N1-bis[(azido-κN)(pyridine-2-carboxamide-κ2N1,O)zinc(II)], Author is Pastor Ramirez, Candida; Bernes, Sylvain; Hernandez Anzaldo, Samuel; Reyes Ortega, Yasmi, the main research direction is dinuclear complex crystal structure chem shift; azido bridge; coordination compound; crystal structure; picolinamide; zinc.Safety of Picolinamide.

The new diamagnetic complex, [Zn2(N3)4(C6H6N2O)2] or [Zn2(pca)2(μ1,1-N3)2(N3)2] was synthesized using pyridine-2-carboxamide (pca) and azido ligands, and characterized using various techniques: IR spectroscopy and single-crystal X-ray diffraction in the solid state, and NMR (NMR) in solution The mol. is placed on an inversion center in space group P [inline formula omitted] . The pca ligand chelates the metal center via the pyridine N atom and the carbonyl O atom. One azido ligand bridges the two symmetry-related Zn2+ cations in the end-on coordination mode, while the other independent azido anion occupies the fifth coordination site, as a terminal ligand. The resulting five-coordinate Zn centers have a coordination geometry intermediate between trigonal bipyramidal and square pyramidal. The behavior of the title complex in DMSO solution suggests that it is a suitable NMR probe for similar or isostructural complexes including other transition-metal ions. The diamagnetic nature of the complex is reflected in similar 1H and 13C NMR chem. shifts for the free ligand pca as for the Zn complex.

Tessier, C.; Rochon, F. D. published an article about the compound: cis-Dichlorobis(pyridine)platinum(II)( cas:15227-42-6,SMILESS:[Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2 ).Formula: C10H10Cl2N2Pt. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:15227-42-6) through the article.

Cis- and trans-Pt(Ypy)2X2, where Ypy is a Me derivative of pyridine and X = Cl or I, were studied by spectroscopic methods, especially by multinuclear NMR spectroscopy. In 195Pt NMR, the cis-dichloro compounds were observed between -1998 and -2021 ppm in CDCl3, while the trans compounds were found at slightly lower field, between -1948 and -1973 ppm. The diiodo species were observed at much higher field, between -3199 and -3288 ppm for the cis isomers and between -3122 and -3264 ppm for the trans isomers. In 1H NMR, the 3J(195Pt-1H) coupling constants are larger for the cis compounds (∼42 ppm) than for the trans isomers (∼33 ppm). In 13C NMR, the values of 3J(195Pt-13C) also are larger for the cis complexes. There seems to be a slight dependence of the pKa values of the protonated ligands on the δ(Pt) chem. shifts. The presence of π-bonding between Pt and the pyridine ligands do not seem very important. The crystal structures of three dichloro and five diiodo complexes were determined, in an attempt to obtain information on the trans influence of the three ligands. The iodo ligand has the greatest trans influence. Chloro and pyridine ligands seem to have similar trans influence, although, the chloro ligand seems to have a slightly larger influence than pyridine derivatives One structure, trans-Pt(2-pic)2I2, showed a syn conformation of the two 2-picoline ligands.
