Related Products of 620-20-2 And the article was included in Journal of Medicinal Chemistry on April 23 ,2020. The article conveys some information:

ERK1 and ERK5 are proposed to have pivotal roles in several types of cancer. Under some circumstance, ERK5 may provide a common bypass route, which rescues proliferation upon abrogation of ERK1 signaling. Thus, we accurately classified the tumor types from The Cancer Genome Atlas (TCGA) based on the expression levels of ERK1 and ERK5. We proposed a novel therapeutic strategy to overcome the above-mentioned compensatory mechanism in specific tumor types by co-targeting both ERK1 and ERK5. On the basis of the idea of overcoming ERK5 compensation mechanism, 22ac (ADTL-EI1712) as the first selective dual-target inhibitor of ERK1 and ERK5 was discovered to have potent antitumor effects in vitro and in vivo. Interestingly, this compound was found to induce regulated cell death accompanied by autophagy in MKN-74 cells. Taken together, our results warrant the potential of this dual-target inhibitor as a new candidate drug that conquers compensatory mechanism in certain tumor types.

The article conveys some information:

This study describes the synthesis of novel 1,3,5-triazine derivatives I (R = H, 2-OMe, 3-NO2, 4-Cl, etc.) as potent inhibitors of cervical cancer. The compounds I were initially tested for inhibition of PI3K/mTOR, where they showed significant inhibitory activity. The top-ranking mol. [compound I (R = 4-OH) (II)] was further tested against class I PI3K isoforms, such as PI3Kα, PI3Kβ, PI3Kγ and PI3Kδ, where it showed the most significant activity against PI3Kα. Compound II was then tested for anti-cancer activity against triple-neg. breast cancer cells (MDA-MB321), human breast cancer cells (MCF-7), human cervical cancer cells (HeLa) and human liver cancer cells (HepG2), and it showed the greatest potency against HeLa cells. The effects of compound II were further evaluated against the HeLa cells, where it showed significant attenuation of cell viability by inducing cell cycle arrest in the G1 phase. Compound II induced apoptosis and reduced migration and invasion of HeLa cells. Western blotting anal. showed that II inhibited PI3K and mTOR with pos. modulation of Bcl-2 and Bax levels in HeLa cells. The effects of compound II were also investigated in a tumor xenograft mouse model, where it showed reduction of tumor volume and weight It also inhibited the PI3K/Akt/mTOR signaling cascade in xenograft tumor tissues, as evidenced by western blotting anal. The results of the present study suggest the possible utility of the designed 1,3,5-triazine derivative I as a potent inhibitor of cervical cancer.

Computed Properties of C7H6Cl2On June 1, 2021, Sui, Yan-Fei; Ansari, Mohammad Fawad; Zhou, Cheng-He published an article in Chemistry – An Asian Journal. The article was 《Pyrimidinetrione-imidazoles as a Unique Structural Type of Potential Agents towards Candida Albicans: Design, Synthesis and Biological Evaluation》. The article mentions the following:

A series of pyrimidinetrione-imidazole conjugates I [R1 = H, Et, 2-chlorobenzl, etc.] as potentially antifungal agents were developed. Bioassays manifested that I [R1 = 4-fluorobenzl] exerted favorable inhibition towards C. albicans (MIC=0.002 mM), being 6.5 folds more active than clin. antifungal drug fluconazole (MIC=0.013 mM). Preliminary mechanism research indicated that compound I [R1 = 4-fluorobenzl] could not only depolarize membrane potential but also permeabilize the membrane of C. albicans. Mol. docking was operated to simulate the interaction mode between mol. I [R1 = 4-fluorobenzl] and CYP51. In addition, hybrid I [R1 = 4-fluorobenzl] might form I [R1 = 4-fluorobenzl]-DNA supramol. complex via intercalating into DNA. The interference of membrane and DNA might contributed to its fungicidal capacity with no obvious tendency to induce the resistance against C. albicans. Conjugate I [R1 = 4-fluorobenzl] endowed good blood compatibility as well as low cytotoxicity towards HeLa and HEK-293T cells. In addition to this study using 3-Chlorobenzylchloride, there are many other studies that have used 3-Chlorobenzylchloride(cas: 620-20-2Computed Properties of C7H6Cl2) was used in this study.

And the article was published in Chemistry – A European Journal in 2010. Category: chlorides-buliding-blocks The author mentioned the following in the article:

Herein is described the development of a novel switch-on fluorescence assay for detecting β-lactamases. The fluorescence assay comprises two components: solid beads coated with a β-lactam antibiotic, which is linked to an environment-sensitive fluorophore (dansylaminothiophenol, DTA), and amyloid fibrils of hen lysozyme (acting as fluorescence enhancer and visual tool). In the presence of the clin. significant TEM-1 β-lactamase, the DTA-antibiotic complex on the solid beads is hydrolyzed, thus releasing the DTA dye into solution The DTA dye is only weakly fluorescent in solution but gives strong green fluorescence upon binding to lysozyme fibrils. These strongly fluorescent DTA-bound fibrils can be easily visualized by the naked eye upon illumination of the sample with a simple UV lamp. The fluorescence assay can detect TEM-1 at low concentration (0.01 nM). In contrast, no observable fluorescence appears when the fluorescence assay is performed on samples without the TEM-1 β-lactamase. In addition to this study using (6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride, there are many other studies that have used (6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride(cas: 79349-53-4Category: chlorides-buliding-blocks) was used in this study.

The article was titled 《Development of a carbon-11 PET radiotracer for imaging TRPC5 in the brain》. The information in the text is summarized as follows:

The transient receptor potential channel subfamily member 5 (TRPC5) is a calcium permeable cation channel widely expressed in the brain. Accumulating evidence indicates that it plays a crucial role in psychiatric disorders including depression and anxiety. Positron emission tomog. (PET) combined with a TRPC5 specific radioligand may provide a unique tool to investigate the functions of TRPC5 in animal disease models to guide drug development targeting TRPC5. To develop a TRPC5 PET radiotracer, the potent TRPC5 inhibitor HC608 was chosen for C-11 radiosynthesis through the N-demethyl amide precursor 7 reacting with [11C]methyl iodide. Under optimized conditions, [11C]HC608 was achieved with good radiochem. yield (25 ± 5%), high chem. and radiochem. purity (>99%), and high specific activity (204-377 GBq μmol-1, decay corrected to the end of bombardment, EOB). The in vitro autoradiog. study revealed that [11C]HC608 specifically binds to TRPC5. Moreover, initial in vivo evaluation of [11C]HC608 performed in rodents and the microPET study in the brain of non-human primates further demonstrated that [11C]HC608 was able to penetrate the blood brain barrier and sufficiently accumulate in the brain. These results suggest that [11C]HC608 has the potential to be a PET tracer for imaging TRPC5 in vivo.

The author of 《Electrical conductivity, ion pairing, and ion self-diffusion in aqueous NaCl solutions at elevated temperatures and pressures》 were Yoon, Tae Jun; Patel, Lara A.; Vigil, Matthew J.; Maerzke, Katie A.; Findikoglu, Alp T.; Currier, Robert P.. And the article was published in Journal of Chemical Physics in 2019. Synthetic Route of ClNa The author mentioned the following in the article:

We have performed classical mol. dynamics (MD) simulations of aqueous sodium chloride (NaCl) solutions from 298 to 674 K at 200 bars to understand the influence of ion pairing and ion self-diffusion on elec. conductivity in high-temperature/high-pressure salt solutions Conductivity data obtained from the MD simulation highlight an apparent anomaly, namely, a conductivity maximum as temperature increases along an isobar, which has been also observed in exptl. studies. By examining both velocity autocorrelation and cross-correlation terms of the Green-Kubo integral, we quant. demonstrate that the conductivity anomaly arises mainly from a competition between the single-ion self-diffusion and the contact ion pair formation. The velocity autocorrelation function in conjunction with structural anal. suggests that diffusive motion of ions is suppressed at high temperatures due to the persistence of an inner hydration shell. The contribution of velocity cross-correlation functions between oppositely charged ions becomes significant at the onset of the conductivity decrease. Structural anal. based on Voronoi tessellation and pair correlation functions indicates that the fraction of contact ion pairs increases as temperature increases. Spatial decomposition of the elec. conductivity also indicates that the formation of contact ion pairs significantly decreases the elec. conductivity compared to Nernst-Einstein conductivity, but the contribution of distant opposite charges cannot be ignored except at the highest temperature due to unscreened long-range interactions.
