And the article contained the following:

Harringtonine (HT), produced from Cephalotaxus species, is known to exhibit potent antiproliferative activity against myeloid leukemia cells by inhibiting protein synthesis. A previous study using acute promyelocytic leukemia (HL-60) cells raised the possibility that the C-5′ Me group of HT plays an important role in regulating leukemia cell line antiproliferative activity. In order to investigate the effect of hydrocarbon chains at C-5′ on the resultant activity, the C-5′ Me group was replaced with various straight- and branched-chain hydrocarbons using the corresponding alcs., and their antiproliferative activity against HL-60 and HeLa cells was investigated. As a result, 4′-n-heptyl-4′-demethylharringtonine (1f, n-heptyl derivative)(I) showed the most potent cytotoxicity among the HT ester derivatives produced, with IC50 values of 9.4 nM and 0.4 μM for HL-60 and HeLa cells, resp. Interestingly, the cytotoxicity of derivative 1f against HL-60 and HeLa cells resp. was ~5 (IC50 = 50.5 nM) and ~10 times (IC50 = 4.0 μM) those of HT and ~2 (IC50 = 21.8 nM) and ~4 times (IC50 = 1.7 μM) more than homoharringtonine (HHT). These results demonstrate the potential of the derivative 1f as a lead compound against leukemia. The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Application In Synthesis of tert-Butyl trichloroacetimidate

Rosenbach, Dominic; Krimalowski, Alexander; Erabhoina, Harimohan; Thelakkat, Mukundan published an article in 2022, the title of the article was Solid polymer electrolytes from polyesters with diester sidechains for lithium metal batteries.Formula: C7H11ClO3 And the article contains the following content:

A series of polymethacrylates and polyacrylates carrying diester side chain moieties with varying alkyl spacer lengths are designed, synthesized, and evaluated as solid polymer electrolytes (SPEs) in lithium metal batteries (LMBs). These amorphous polymers with glass transition temperatures in the range of -58 to +32 °C are tested as SPEs in combination with LiTFSI or LiFSI. At an optimum salt concentration of 25 wt%, ionic conductivities up to 10-4 S cm-1 at 70 °C are achieved. These SPEs reveal high lithium transport numbers (0.5-0.7) and high electrochem. stability (5.4 V vs. Li/Li+) as determined by LSV. In combination with an ultrathin polyimide membrane and 10 wt% TiO2 nanoparticles, dendrite-free plating/stripping at 40 and 70 °C is realized in sym. Li|SPE|Li cells. Detailed extended distribution of relaxation times (eDRT) anal. of impedance measurements is employed for understanding the diverse cell processes. In solvent-free LMBs comprising a polyimide membrane soaked with the nanocomposite polyester electrolyte, lithium metal foil as the anode and an optimized LiFePO4 cathode, a very high initial specific discharge capacity of 152 mA h g- 1 (at 0.2C, 70 °C), excellent capacity retention of 94% after 100 cycles (at 1C, 70 °C) and negligible capacity fading even at 2C (96% retention after 300 cycles) are demonstrated. These novel polyester-based SPEs exhibit high cycling stability at 40 °C, making them highly attractive for room temperature applications. The experimental process involved the reaction of Methyl 6-chloro-6-oxohexanoate(cas: 35444-44-1).Formula: C7H11ClO3

On March 15, 2021, Abdulwahab, Muhammad Kumayl; Tan, Ke Han; Dzulkeflee, Rashidi; Leong, Kok Hoong; Heh, Choon Han; Ariffin, Azhar published an article.Safety of 2-Amino-4-chlorobenzoic acid The title of the article was In-silico Studies of the Antiproliferative Activity of New Anilinoquinazoline Derivatives Against NSCLC Cells.. And the article contained the following:

The current reversible epidermal growth factor (EGFR) tyrosine kinase inhibitors of non-small cell lung cancer (NSCLC) have been resisted by T790M mutation, while the irreversible inhibitors introduced to overcome the mutation have faced resistance from C979S mutation. In the effort to discover potentially improved reversible EGFR inhibitors, a series of new anilinoquinazoline derivatives with modification on the 2nd carbon on the aniline ring was synthesized. The derivatives were tested for their antiproliferative activity against NSCLC cell lines with wild-type (A549), exon 19 deletion mutated (H1650) and L858R+T790M (H1975) mutated EGFR kinases. Three derivatives (4-6) performed better than the standard drug, gefitinib, in all cell lines. Derivative 5 recorded the lowest IC50 values in all cell lines (A549: 24.60 ± 0.75 μM, H1650: 14.83 ± 0.54 μM, H1975: 21.72 ± 1.21 μM). A mol. docking study followed by mol. dynamics simulations was performed on derivative 5 and gefitinib using wild-type EGFR kinase (WT-EGFR) and L858R+T790M mutated kinase (LRTM-EGFR) to provide an understanding of their binding mechanisms. In WT-EGFR kinase, derivative 5 recorded better hydrogen bonding occupancy with MET793 (94.16%) and binding energy profile (-35.287 kcal/mol) as compared to gefitinib (91.80%, -26.071 kcal/mol). In LRTM-EGFR kinase, derivative 5 recorded better hydrogen bonding occupancy with MET793 (93.68%) as compared to gefitinib (91.48%). Derivative 5 also recorded addnl. hydrogen bonding interactions with ASP855, with a total of 60.61% occupancy as well as a better energy profile (-42.867 kcal/mol) as compared to gefitinib (-41.778 kcal/mol).

On May 19, 2022, Sabbah, Dima A.; Samarat, Hla H.; Al-Shalabi, Eveen; Bardaweel, Sanaa K.; Hajjo, Rima; Sweidan, Kamal; Khalaf, Reema Abu; Al-Zuheiri, Aya M.; Abushaikha, Ghassan published an article.Name: 2-Amino-4-chlorobenzoic acid The title of the article was Design, Synthesis, and Biological Examination of N-Phenyl-6-fluoro-4-hydroxy-2-quinolone-3-carboxamides as Anticancer Agents. And the article contained the following:

Cancer is one of the leading causes of death worldwide, and it has a major impact on public health. Phosphatidylinositol 3-kinase (PI3Kα) has been recognized as a promising drug target for developing anticancer agents. Herein, a series of N-phenyl-6-fluoro-4-hydroxy-2-quinolone-3-carboxamides was developed to target PI3Kα. All synthesized compounds were characterized using FT-IR, NMR (1H and 13C) and elemental anal. All synthesized chem. analogs exerted distinctive anticancer activity. They inhibited the growth of human epithelial colorectal adenocarcinoma (Caco-2) with IC50 values between 48.63-378 μM, and human colon cancer (HCT-116) cell lines with IC50 values between 44-664 μM. Computational modeling studies provided important biol. insight. Induced-fit docking (IFD) studies showed that the synthesized chem. analogs fit the kinase catalytic domains and form a significant H-bond interaction network with key amino acids at the biding site. Furthermore, cheminformatics analyses indicated that all synthesized compounds were drug-like permitting further animal testing or clin. development.

On December 31, 2018, Cao, Zhong-Yan; Ghosh, Tamal; Melchiorre, Paolo published an article.Application In Synthesis of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate The title of the article was Enantioselective radical conjugate additions driven by a photoactive intramolecular iminium-ion-based EDA complex. And the article contained the following:

The photochem. activity of electron donor-acceptor (EDA) complexes provides a way to generate radicals under mild conditions. This strategy has found application in chem. synthesis and recently in enantioselective catalysis. Reported methods classically relied on the formation of intermol. EDA complexes, generated upon aggregation of two suitable reagents. Herein, we further expand the synthetic utility of this strategy demonstrating that an intramol. EDA complex can trigger a photochem. catalytic enantioselective radical process. This approach enables radical conjugate additions to β-substituted cyclic enones to form quaternary carbon stereocenters with high stereocontrol using visible light irradiation Crucial for success is the use of an amine catalyst, adorned with a carbazole moiety, which generates, upon condensation with enones, chiral iminium ions that show a broad absorption band in the visible region. This optical property originates from an intramol. charge transfer π-π interaction between the electron-rich carbazole nucleus and the electron-deficient iminium double bond. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Application In Synthesis of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate

On April 1, 2022, Choi, Sungyu; Shin, Sang-Hun; Lee, Dong-Hyun; Doo, Gisu; Lee, Dong Wook; Hyun, Jonghyun; Yang, Seok Hwan; Man Yu, Duk; Lee, Jang Yong; Kim, Hee-Tak published an article.Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Oligomeric chain extender-derived poly(p-phenylene)-based multi-block polymer membranes for a wide operating current density range in polymer electrolyte membrane water electrolysis. And the article contained the following:

Hydrocarbon-based membranes can extend the operating current range of a polymer electrolyte membrane water electrolyzer (PEMWE) because of their low gas permeability and high proton conductivity However, increasing the ion exchange capacity for sufficiently high proton conductivity leads to poor mech. stability and increased gas permeability for hydrocarbon-based membranes. This study presents a poly(p-phenylene)-based multiblock polymer with an oligomeric chain extender (CE-sPP-PPES) for improved mech. stability and extended operating current range. With the introduction of a chain extender, the mech. and chem. stability were notably enhanced. The effects of ion exchange capacity on mech. properties, proton conductivity, and hydrogen crossover were investigated compared to a Nafion membrane. The CE-sPP-PPES-based PEMWE has a 2.1 times wider operating current range than a Nafion-based PEMWE because of its smaller ohmic overvoltage and lower gas crossover at an optimal ion exchange capacity, demonstrating the possibility of a new hydrocarbon-based membrane for PEMWE.
