And the article contained the following:

A novel series of 6-methoxy-1-tetralone derivatives bearing N-aryl pyridinium moiety I (Ar = C6H5, 2-FC6H4, 3-ClC6H4, etc.; n = 1, 2, 3, 4, 5; X = Cl, Br) were designed, synthesized, and evaluated as acetyl and butyrylcholinesterase inhibitors. The designed derivatives inhibited acetylcholinesterase (AChE) with IC50 values of 0.025-23.743μM and butyrylcholinesterase (BChE) with IC50 values of 0.716-20.588μM. The synthesized compounds were divided into two series. Derivatives containing N-benzyl moieties generally were more potent anti-AChE and anti-BChE agents than compounds with N-alkylphthalimide groups. Among them, the compound I (Ar = C6H5; n = 1; X = Br) and compound I (Ar = 3-ClC6H4; n = 1; X = Br) exhibited significant inhibitory activity against AChE and BChE with IC50 values of 0.025 and 0.716μM in comparison to donepezil as a reference drug (0.029 and 0.948μM, resp.). The results of kinetic and mol. modeling studies demonstrated that the synthesized compounds I (Ar = C6H5; n = 1; X = Br) and I (Ar = 3-ClC6H4; n = 1; X = Br) derivatives can act as mixed and dual binding inhibitors, and bind to both CAS and PAS of AChE and BChE enzymes. Among the assessed compounds, the compound I (Ar = C6H5; n = 1; X = Br) indicated significant neuroprotection against H2O2-induced cell death in PC12 cells. So, these findings indicate the therapeutic potential of 6-methoxy-1-tetralone derivatives bearing N-aryl pyridinium moiety derivatives as anti-AD agents. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).COA of Formula: C10H8BrNO2

On September 30, 2020, Ruan, Qing; Zhang, Xuran; Zhang, Junbo published an article.COA of Formula: C10H8BrNO2 The title of the article was Radiosynthesis and evaluation of novel [99mTc(I)]+ and [99mTc(I)(CO)3]+ complexes with a 4-nitroimidazole isocyanide for imaging tumor hypoxia. And the article contained the following:

[99mTc(I)]+ and [99mTc(I)(CO)3]+ complexes with isocyanide exhibit high stability, which makes them suitable platforms to develop novel 99mTc radiopharmaceuticals. To develop novel 99mTc radiotracers for imaging hypoxia, a novel L ligand (4-nitroimidazole isocyanide derivative) was synthesized and labeled using [99mTc(I)]+ core and [99mTc(I)(CO)3]+ core to produce [99mTc(L)6]+ and [99mTc(CO)3(L)3]+ with high yields. To verify the structure of the 99mTc complexes, corresponding rhenium analogs were synthesized and characterized. Both of the 99mTc complexes were stable and hydrophilic. in vitro cellular uptake results showed they could exhibit good hypoxic selectivity. The evaluation of biodistribution in mice bearing S180 tumors indicated both of them could accumulate in tumor. Between them, [99mTc(L)6]+ exhibited higher tumor uptake and tumor/non-target ratio than [99mTc(CO)3(L)3]+. Further, single photon emission computed tomog. (SPECT) imaging studies of [99mTc(L)6]+ indicated an obvious accumulation in tumor and the value of the region-of-interest (ROI) ratio of the uptake for the tumor site to the corresponding non-tumor region was 5.64 ± 0.52. The above results suggested [99mTc(L)6]+ would be a potential tracer for imaging tumor hypoxia.

On December 1, 2020, Rezaeivala, Majid; Ahmadi, Musa; Captain, Burjor; Bayat, Mehdi; Saeidirad, Mahdi; Sahin-Bolukbasi, Serap; Yildiz, Batuhan; Gable, Robert William published an article.Application In Synthesis of 2-(2-Bromoethyl)isoindoline-1,3-dione The title of the article was Some new morpholine-based Schiff-base complexes; Synthesis, characterization, anticancer activities and theoretical studies. And the article contained the following:

A new morpholine-based ligand (2) has been prepared from condensation of a branched amine containing morpholine, N1-(3-morpholinopropyl)-N1-((pyridine-2-yl)methyl)ethane-1,2-diamine (1), and salicylaldehyde. Metal complexes were synthesized by reaction of the ligand and metal salts in ethanol and the resulting products were characterized by elemental analyses, ESI-MS, 1H and 13C NMR spectra, IR, and UV-Vis spectroscopy. The structure of two complexes including [ZnL](ClO4) (3) and [NiHL](ClO4)·H2O (6a) have been determined by single crystal X-ray structural anal., showing that the metal atoms are in a distorted trigonal bipyramidal (Zn) and a square planar (Ni) environment, resp. Compounds were assayed for their anticancer activities against a panel of human tumor cell lines, including breast cancer cells (MCF-7, MDA-MB-231), prostate cancer cells (PC-3) and human normal lung fibroblast cells (WI-38). Compounds 1, 2, 7, 9 and 10 demonstrated lower activity against MCF-7, MDA-MB-231 and PC-3 cell lines (IC50s > 100μM) compared to other compounds It has been shown that complexes 3, 4, 5, 6, and 8 possess different anticancer potentials against MCF-7, MDA-MB-231 and PC-3. More importantly, it was observed that compounds 3, 5 and 6 demonstrate a lower activity against WI-38 normal cell line than they do against cancer cell lines. Our results indicated that compound 8 has the highest anticancer activity on cancer cell lines, and the reason for that can be attributed to the presence of a silver atom in the complex. These results clearly showed that the anticancer activities of these compounds depend on the type of metal in the complex as well as the tested cancer cell line. Furthermore, the geometries of the [ML]n+ (M = Zn2+, Cd2+, Mn2+, Cu2+, Ni2+, Ag+, Fe3+ and Co2+, n = 0, 1, 2) complexes have been optimized at the BP86/def2-SVP level of theory. The nature of M → L bonds in [ML]n+ complexes have been studied with the help of NBO anal.

And the article contained the following:

Organic compounds obtained by click chem. reactions have demonstrated a broad spectrum of biol. activities being widely applied for the development of mols. against pathogens of medical and veterinary importance. Cutaneous leishmaniasis (CL), caused by intracellular protozoa parasite of genus Leishmania, comprises a complex of clin. manifestations that affect the skin and mucous membranes. The available drugs for the treatment are toxic and costly, with long periods of treatment, and the emergence of resistant strains has been reported. In this study we investigated the in vitro effects of a phthalimide-1,2,3-triazole derivative, the 4-Phenyl-1-[2-(phthalimido-2-yl)ethyl]-1H-1,2,3-triazole (PT4) obtained by click chem., on mammalian cells and on L. amazonensis and L. braziliensis, the causative agents of CL in Brazil. In silico ADMET evaluation of PT4 showed that this mol. has good pharmacokinetic properties with no violation of Lipinski’s rules. The in vitro assays showed that PT4 was more selective for both Leishmania species than to mammalian cells. This compound also presented low cytotoxicity to mammalian cells with CC50 > 500μM. Treatment of promastigote forms with different concentrations of PT4 resulted in ultrastructural alterations, such as plasma membrane wrinkling, shortening of cell body, increased cell volume and cell rupture. The mol. dynamic simulations showed that PT4 interacts with Lanosterol 14 α-demethylase from Leishmania, an essential enzyme of lipid synthesis pathway in this parasite. Our results demonstrated PT4 was effective against both species of Leishmania. PT4 caused a decrease of mitochondrial membrane potential and increased production of reactive oxygen species, which may lead to parasite death. Taken together, our results pointed PT4 as promissing therapeutic agent against CL. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).SDS of cas: 574-98-1

Kurogi, Takashi; Chu, Jiaxiang; Chen, Yaofeng; Mindiola, Daniel J. published an article in 2019, the title of the article was Neutral and Anionic Monomeric Zirconium Imides Prepared via Selective C=N Bond Cleavage of a Multidentate and Sterically Demanding β-Diketiminato Ligand.HPLC of Formula: 574-98-1 And the article contains the following content:

A sterically encumbering multidentate β-diketiminato ligand, tBuL2 (tBuL2=[ArNC(tBu)CHC(tBu)NCH2CH2N(Me)CH2CH2NMe2]-, Ar = 2,6-iPr2C6H3), is reported in this study along with its coordination chem. to zirconium(IV). Using the lithio salt of this ligand, Li(tBuL2) (4), the zirconium(IV) precursor (tBuL2)ZrCl3 (6) could be readily prepared in 85% yield and structurally characterized. Reduction of 6 with 2 equiv of KC8 gave the terminal and mononuclear zirconium imide-chloride [C(tBu)CHC(tBu)NCH2CH2N(Me)CH2CH2NMe2]Zr(=NAr)(Cl) (7) as the result of reductive C=N cleavage of the imino fragment in the multidentate ligand tBuL2 by an elusive ZrII species (tBuL2)ZrCl (A). The azabutadienyl ligand in 7 can be further reduced by 2 e- with KC8 to afford the anionic imide [K(THF)2]{[CH(tBu)CHC(tBu)NCH2CH2N(Me)CH2CH2N(Me)CH2]Zr = NAr} (8-2THF) in 42% isolated yield. Complex 8-2THF results from the oxidative addition of an amine C-H bond followed by migration to the vinylic group of the formal [C(tBu)CHC(tBu)NCH2CH2N(Me)CH2CH2NMe2]- ligand in 7. All halides in 6 can be replaced with azides to afford (tBuL2)Zr(N3)3 (9) which was structurally characterized, and reduction with two equiv of KC8 also results in C=N bond cleavage of tBuL2 to form [C(tBu)CHC(tBu)NCH2CH2N(Me)CH2CH2NMe2]Zr(=NAr)(N3) (10), instead of the expected azide disproportionation to N3- and N2. Solid-state single crystal structural studies confirm the formation of mononuclear and terminal zirconium imido groups in 7, 8-Et2O, and 10 with Zr = NAr distances being 1.8776(10), 1.9505(15), and 1.881(3) Å, resp.

On August 1, 2019, Holub, Jan; Santoro, Antonio; Lehn, Jean-Marie published an article.Product Details of 574-98-1 The title of the article was Electronic absorption and emission properties of bishydrazone [2 × 2] metallosupramolecular grid-type architectures. And the article contained the following:

Several ditopic ligands containing two tridentate bishydrazone coordination subunits and their Zn(II) and Cd(II) [2 × 2] grid-type complexes were prepared and their photoluminescent properties studied. A special attention was devoted to the influence of the orientation of the hydrazone group N-N=in the core of the ligands and their complexes. Its reversal from [pyridine=N-N-pyrimidine] (L1) to [pyridine-N-N=pyrimidine] (L2) has a strong impact on the observed absorption and emission behavior of particular ligands (L1 and L2) as well as of their [2 × 2] grid assemblies. The further lateral functionalization of the ligands led to different emission quantum yields of the resulting grids, while their emission and absorption spectra varied very little. The simplest derivative L1 turned out to have the best performance with, for its Zn(II) complex, relatively high quantum yield 60%. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Product Details of 574-98-1

On May 6, 2019, Yang, Xianteng; Wang, Fan; Zhu, Hua; Yang, Zhi; Chu, Taiwei published an article.SDS of cas: 574-98-1 The title of the article was Synthesis and Bioevaluation of Novel [18F]FDG-Conjugated 2-Nitroimidazole Derivatives for Tumor Hypoxia Imaging. And the article contained the following:

Hypoxia imaging can guide tumor treatment and monitor changes in hypoxia during treatment. However, there is still no ideal hypoxia imaging agent for clin. applications. In this study, two novel 2-nitromidazole derivatives were synthesized and directly radiolabeled by [18F]FDG in high radiochem. yield and excellent radiochem. purity. Cell experiments, biodistribution, and positron emission tomog. (PET) imaging studies were also conducted in mice-bearing S180 or OS732 tumors. [18F]FDG-2NNC2ON [(2R,3S,4R,E)-2-18F-fluoro-3,4,5,6-tetrahydroxyhexanal O-3-(2-(2-nitro-1H-imidazole-1-yl)ethylamino)-2-oxopropyl oxime] and [18F]FDG-2NNC5ON [(2R,3S,4R,E)-2-18F-fluoro-3,4,5,6-tetrahydroxyhexanal-O-3-(5-(2-nitro-1H-imidazole-1-yl)pentylamino)-2-oxopropyl oxime] can be cleared from the blood quickly and specifically target hypoxic tumor cells. The uptake of the probes by hypoxic cells gradually increases with time. After 4 h, the uptake value of [18F]FDG-2NNC2ON in hypoxic cells is 3.2 times higher than that in normoxia cells. In contrast, there is no difference in the uptake of [18F]FDG between hypoxic cells and normoxia cells. Biodistribution resulting from two tumor models indicate that the uptake values of the two radiotracers in the tumor are higher at 1 h than those at 2 and 4 h. At 1 and 2 h, the tumors are clearly observed on the PET images and the imaging features of [18F]FDG-2NNC5ON and [18F]FDG-2NNC2ON are distinct from those of [18F]FDG. Compared with [18F]FDG-2NNC5ON, [18F]FDG-2NNC2ON has a higher proportion of renal excretion, lower digestive tract uptake, and better imaging contrast because of its higher hydrophilicity. At 2 h, [18F]FDG-2NNC2ON shows a good tumor-to-blood (T/B) ratio, tumor-to-muscle ratio based on biodistribution (Bio-T/M ratio), and tumor-to-muscle ratio based on regions of interest on the PET images [region of interest (ROI)-T/M ratio] in the two tumor models (T/B, Bio-T/M, and ROI-T/M ratios are 3.2, 2.6, and 3.9 in the S180 tumor model and are 3.4, 4.2, and 4.6 in the OS732 tumor model, resp.). The imaging features visualized with autoradiog. mostly coincided with the pos. areas of HIF1α staining by immunofluorescence. Meanwhile, the biodistribution study and PET imaging revealed that the uptake of the radiotracers in the tumor cannot be competed by 5% glucose, confirming that [18F]FDG-2NNC2ON targets the hypoxic regions of the tumors instead of targeting tumors through the glucose metabolism pathway. These results suggest that the new 2-nitroimidazole derivative conjugated with [18F]FDG, [18F]FDG-2NNC2ON, has potential as an imaging agent for hypoxia.

And the article contained the following:

To develop novel 99mTc labeled nitroimidazole imaging agents for imaging tumor hypoxia, 99mTc labeled ethylene diamine tetraacetic acid derivative of 4-nitroimidazole was reported by us earlier, which showed disadvantage of an unsatisfactory tumor-to-blood ratio. Therefore, 2-nitroimidazole was adopted as a pharmacophore to synthesize EDTA-2-EtNHNM, which was radiolabeled with 99mTc in high yield to achieve 99mTc-EDTA-2-EtNHNM. 99mTc-EDTA-2-EtNHNM was hydrophilic and exhibited good in vitro stability. Cellular experiment demonstrated its hypoxic selectivity while biodistribution results showed improved tumor-to-blood and tumor-to-muscle ratios. SPECT imaging studies of 99mTc-EDTA-2-EtNHNM indicated obvious accumulation in tumor, suggesting its potential to be a radiotracer for imaging tumor hypoxia.
