Recommanded Product: 110-52-1. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1,4-Dibromobutane, is researched, Molecular C4H8Br2, CAS is 110-52-1, about Multicomponent click polymerization for the synthesis of coumarin containing 1,4-polytriazoles and their application as dye adsorbent. Author is Bhaumick, Prabhas; Choudhury, Lokman H..

The synthesis of heterocycle-based polymers have remained an important area of research in polymer chem. Herein we report a one-pot synthesis of a set of novel coumarin containing regioselective 1,4-polytriazols by multicomponent click polymerization using Cs2CO3 as a base and copper(I) acetate as a catalyst in DMF medium. In this one-pot process, O-alkylation followed by a three-component click reaction between the coumarin-linked dialkyne, sodium azide and alkyl/benzyl dibromides provide novel polymers having coumarin-triazole-linker (C-T-L) units. Ten novel polymers have been synthesized with high mol. weights (Mw = 20,080-46,340 g/mol) and very good yields (83-93%). All the polymers were well characterized by IR, NMR, and GPC. The dye removal capacities of these polymers were evaluated for methylene blue (MB), rhodamine B (RB), methyl orange (MO), and congo red (CR). Polymers P1, P2, and P3 showed very high affinity towards methylene blue dye and among them, P2 showed the highest dye removal efficiency (971 mg/g) for MB. The reusability of P2 was checked and found excellent removal efficiency (RE = 96%) up to the eighth cycle.

To evaluate the impact of upper tract urothelial carcinoma (UTUC) on bacillus Calmette-Guerin (BCG) response and progression in patients with non-muscle-invasive bladder cancer (NMIBC). We performed an institutional review board-approved review of patients with NMIBC treated with adequate intravesical BCG, as defined by the US Food and Drug Administration, at our institution between 2000 and 2018. Patients were stratified by presence of any UTUC and time of UTUC diagnosis (preceding vs synchronous to NMIBC diagnosis or metachronous disease after NMIBC diagnosis). Descriptive statistics were used to summarize the data overall and by groups, and t-tests or Wilcoxon’s rank sum tests and Pearson’s chi-squared or Fisher’s exact tests were used to analyze continuous and categorical data, resp. Of 541 patients with NMIBC treated with adequate BCG, 59 (10.9%) were diagnosed with UTUC. Of these, 34 had a history of UTUC prior to NMIBC (UTUC-P; median [interquartile range {IQR}] 13.1 [7.4-27.6] months prior), while 25 developed UTUC after diagnosis of NMIBC (six synchronous and 19 metachronous; median [IQR] 12.1 [1.7-28.1] months after). Compared to the non-UTUC group, patients with UTUC-P were more likely to exhibit Tis without papillary tumor in the bladder (20.6% vs 5.0%; P < 0.001), but were less likely to have T1 disease on index transurethral resection (8.8% vs 49.4%; P < 0.001). Patients with UTUC-P developed more recurrences (55.9% vs 34.0%; P = 0.010), any stage/grade progression (23.5% vs 9.8%; P = 0.012) and progression to muscle-invasive or metastatic disease (17.6% vs 6.4%; P = 0.014). The presence of high-grade UTUC-P compared to low-grade UTUC-P was associated with increased NMIBC recurrence (68.2% vs 25.0%; P = 0.049). There was no significant difference in rates of recurrence or progression based on timing of UTUC with respect to the index bladder tumor, although this anal. was limited by small numbers Presence of UTUC prior to a diagnosis of NMIBC was associated with an almost twofold increased recurrence and progression rates after adequate BCG therapy. This should be considered when counselling patients and designing cohorts for clin. trials.

Ni(II)-catalyzed asym. alkenylation of cyclic ketimines I [R = Me, cyclopropyl, CO2Me, etc.; R1 = H, 8-Me, 7-Cl, etc.; n = 0, 1] with R2CH=CHB(OH)2 (R2 = n-Pr, cyclohexyl, Ph, etc.) for the preparation of chiral allylic amines II was reported. The method well tolerated a variety of ketimines and alkenylboronic acids R2CH=CHB(OH)2 and afforded the desired products in good yields (up to 99%) and enantioselectivities (up to >99% ee). A Ni(II)-catalyzed asym. cascade alkenylation/ring-expansion reaction of alkenyl cyclic ketimines was also developed to yield a series of seven-membered chiral sulfonamides III [R3 = t-Bu, i-Pr, cyclohexyl.; R4 = C6H5, 3-FC6H4, etc.] with good yields and enantioselectivities under mild reaction conditions. This reaction was also an efficient method for the preparation of trisubstituted conjugated dienes. Mechanistic studies showed that the alkenylation was the enantioselectivity-determining step, while the ring expansion step was a stereospecific process. The site-selectivity of the ring rearrangement expansion could be controlled by the formation of a large p-conjugated system or by steric interactions. Transformations of products for both types of reactions were also conducted to show the potential applications of this methodologies.

The treatment of several 2-diphenylphosphinoimidazoles with Pd(II) salts generates monosubstituted N-H NHC-Pd complexes via insertion into the C-P bond is reported. Removal of the N-H proton in situ leads to anionic (X-type) or imidazolyl-Pd complexes that are highly stable and catalytically active, achieving up to 340,000 turnovers at 1 ppm catalyst loading in Suzuki-Miyaura reactions. DFT-calculated Tolman electronic parameters for the sterically small ligands suggest that these ligands are significantly more donating than traditional NHCs, which provides a rationale for rapid cross-coupling catalysis.

Compound: 2-Phenylpyridine, is researched, Molecular C11H9N, CAS is 1008-89-5, about Mitochondria-targeted artesunate conjugated cyclometalated iridium(III) complexes as potent anti-HepG2 hepatocellular carcinoma agents.

Hepatocellular carcinoma (HCC) poses a serious threat to people′s health worldwide. Artesunate (ART), one of the classical antimalarial drugs, has recently been shown to exert significant cytotoxicity in various cancers, but its bioavailability is low. Cyclometalated iridium(III) complexes have emerged as a promising class of anticancer therapeutic agents. Herein, through conjugation of two of them, three novel Ir(III)-ART conjugates, [Ir(C-N)2(bpy-ART)](PF6) (bpy = 2,2′-bipyridine, C-N = 2-phenylpyridine (ppy, Ir-ART-1), 2-(2-thienyl)pyridine (thpy, Ir-ART-2), and 2-(2,4-difluorophenyl)pyridine (dfppy, Ir-ART-3)) have been synthesized, and their potential as anti-HCC agents was evaluated. We demonstrate that Ir-ART-1-3 display higher cytotoxicity against HCC cell lines than normal liver cells, and they can especially locate to mitochondria of HepG2 cells and induce a series of mitochondria-mediated apoptosis events. Moreover, Ir-ART-1-3 can regulate the cell cycle and inhibit metastasis of HepG2 cells. Finally, in vivo antitumor evaluation also demonstrates the inhibitory activity of Ir-ART-1 on tumor growth. Taken together, these Ir(III)-ART conjugates have the potential to become drug candidates for future anti-HCC treatments.
