An article called Amphiphilic Star-Shaped Calix[4]resorcinarene as Stationary Phase for Capillary Gas Chromatography, published in 2019-11-30, which mentions a compound: 693-67-4, Name is 1-Bromoundecane, Molecular C11H23Br, Computed Properties of C11H23Br.

This work describes the separation performance of the amphiphilic star-shaped calix[4]resorcinarene (C4A-CL)(I) as the stationary phase for capillary gas chromatog. (GC). The statically coated C4A-CL capillary column exhibited medium polarity and high column efficiency of 3877 plates m-1 determined by naphthalene at 120 °C. Importantly, the C4A-CL column exhibited extremely high resolving capability for aliphatic analytes with varying polarity, including n-alkanes, esters, ketones, alcs., and bromoalkanes. In addition, the C4A-CL column exhibited high selectivity and resolving capability for positional, structural and cis-/trans-isomers. Among them, the C4A-CL column displayed advantageous resolving capability over the com. DB-17 column for aromatic amine isomers. Moreover, it was applied for the determination of isomer impurities in real samples, showing good potential in GC applications.

CDK7 has emerged as an exciting target in oncol. due to its roles in two important processes that are misregulated in cancer cells: cell cycle and transcription. This report describes the discovery of SY-5609, a highly potent (sub-nM CDK7 Kd) and selective, orally available inhibitor of CDK7 that entered the clinic in 2020 (ClinicalTrials.gov Identifier: NCT04247126). Structure-based design was leveraged to obtain high selectivity (>4000-times the closest off target) and slow off-rate binding kinetics desirable for potent cellular activity. Finally, incorporation of a phosphine oxide as an atypical hydrogen bond acceptor helped provide the required potency and metabolic stability. The development candidate SY-5609 displays potent inhibition of CDK7 in cells and demonstrates strong efficacy in mouse xenograft models when dosed as low as 2 mg/kg.

SDS of cas: 693-67-4. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Discovery, characterization and functional improvement of kumamonamide as a novel plant growth inhibitor that disturbs plant microtubules. Author is Ishida, Takashi; Yoshimura, Haruna; Takekawa, Masatsugu; Higaki, Takumi; Ideue, Takashi; Hatano, Masaki; Igarashi, Masayuki; Tani, Tokio; Sawa, Shinichiro; Ishikawa, Hayato.

In the present study, authors discovered a novel N-alkoxypyrrole compound, kumamonamide from Streptomyces werraensis MK493-CF1 and established a total synthesis procedure. Resulted in the bioactivity assays, it was found that kumamonamic acid, a synthetic intermediate of kumamonamide, is a potential plant growth inhibitor. Further, various derivatives of kumamonamic acid are developed, including a kumamonamic acid nonyloxy derivative (KAND), which displayed high herbicidal activity without adverse effects on HeLa cell growth. Authors also detected that kumamonamic acid derivatives disturb plant microtubules; and addnl., that KAND affected actin filaments and induced cell death. These multifaceted effects differ from those of known microtubule inhibitors, suggesting a novel mode of action of kumamonamic acid, which represents an important lead for the development of new herbicides.

Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Even-Odd Alkyl Chain-Length Alternation Regulates Oligothiophene Crystal Structure.

Alkyl chains of varied length and steric bulk are generally appended to π-conjugated chromophores to increase solubility These alkyl chains also regulate many aspects of the solid-state packing and, in turn, resultant electronic and optical properties of organic semiconductors, yet there remains little understanding as to how these moieties govern such characteristics. Here, we report on a series of (2,5-bis(3-alkylthiophen-2-yl) thieno[3,2-b]thiophenes) (BTTT) monomers where the single-crystal packing configurations and m.ps. alternate as a function of whether the alkyl side chains have an even or odd number of carbon atoms. When the alkyl chains contain an even number of carbon atoms, the mols. predominantly crystallize with the BTTT units of the stacked lamellae aligned in the same direction. In contrast, when the number of carbon atoms is odd, alternating lamellae are twisted with respect to their neighbors, i.e. the BTTT moieties in one layer are aligned in an orthogonal-like fashion to those in its neighboring lamellae, and the crystal m.ps. tend to be higher than those with the even-numbered alkyl chains. With d. functional theory calculations and geometric analyses, the variations in crystal structure and thus the differences in phys. properties are rationalized by an oscillating interlayer interaction that is a function of alkyl side chain atom count and length. This study characterizes an extreme case of an organic semiconductor crystal packing alternation to highlight the effect of even-odd assembly as an underutilized and under-reported handle for tuning the mol. packing of organic semiconductor materials.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1-Bromoundecane( cas:693-67-4 ) is researched.Electric Literature of C11H23Br.Zhang, Dapeng; Atochina-Vasserman, Elena N.; Maurya, Devendra S.; Huang, Ning; Xiao, Qi; Ona, Nathan; Liu, Matthew; Shahnawaz, Hamna; Ni, Houping; Kim, Kyunghee; Billingsley, Margaret M.; Pochan, Darrin J.; Mitchell, Michael J.; Weissman, Drew; Percec, Virgil published the article 《One-Component Multifunctional Sequence-Defined Ionizable Amphiphilic Janus Dendrimer Delivery Systems for mRNA》 about this compound( cas:693-67-4 ) in Journal of the American Chemical Society. Keywords: ionizable amphiphilic Janus dendrimer delivery system mRNA. Let’s learn more about this compound (cas:693-67-4).

Efficient viral or nonviral delivery of nucleic acids is the key step of genetic nanomedicine. Both viral and synthetic vectors have been successfully employed for genetic delivery with recent examples being DNA, adenoviral, and mRNA-based Covid-19 vaccines. Viral vectors can be target specific and very efficient but can also mediate severe immune response, cell toxicity, and mutations. Four-component lipid nanoparticles (LNPs) containing ionizable lipids, phospholipids, cholesterol for mech. properties, and PEG-conjugated lipid for stability represent the current leading nonviral vectors for mRNA. However, the segregation of the neutral ionizable lipid as droplets in the core of the LNP, the “”PEG dilemma””, and the stability at only very low temperatures limit their efficiency. Here, we report the development of a one-component multifunctional ionizable amphiphilic Janus dendrimer (IAJD) delivery system for mRNA that exhibits high activity at a low concentration of ionizable amines organized in a sequence-defined arrangement. Six libraries containing 54 sequence-defined IAJDs were synthesized by an accelerated modular-orthogonal methodol. and coassembled with mRNA into dendrimersome nanoparticles (DNPs) by a simple injection method rather than by the complex microfluidic technol. often used for LNPs. Forty four (81%) showed activity in vitro and 31 (57%) in vivo. Some, exhibiting organ specificity, are stable at 5°C and demonstrated higher transfection efficiency than pos. control experiments in vitro and in vivo. Aside from practical applications, this proof of concept will help elucidate the mechanisms of packaging and release of mRNA from DNPs as a function of ionizable amine concentration, their sequence, and constitutional isomerism of IAJDs.

A novel, water-soluble trans-platinum complex was synthesized by inclusion complexation with β-cyclodextrin. The complexation was confirmed by 1H NMR, FT-IR, TGA, and XRD as well as by SEM and EDX. As the precursor complex is not water-soluble, it is difficult to employ it for biol. applications. Here, we report that the encapsulation with cyclodextrin allowed to solubilize the complex to a solubility value of 1.6 mg/mL. Moreover, the cytotoxicity in vitro of the novel inclusion complex indicated a much higher activity after encapsulation.
