In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of axially disubstituted silicon(IV) phthalocyanines and investigation of their photophysical and photochemical properties, published in 2022-02-05, which mentions a compound: 67914-60-7, Name is 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, Molecular C12H16N2O2, Computed Properties of C12H16N2O2.

In this study, the axially 1-(4-(3-(6-hydroxyhexyl)-3,4-dihydro-2H-benzo[e][1,3]oxazin-6-yl)piperazin-1-yl)ethanone and 1-(4-(3-(2-(2-hydroxyethoxy)ethyl)-3,4-dihydro-2H-benzo[e][1,3]oxazin-6-yl)piperazin-1-yl)ethanone disubstituted silicon(IV) phthalocyanines and their corresponding quaternized derivatives were synthesized for the first time as candidate photosensitizers for photodynamic therapy (PDT) in cancer treatment. The structures of these novel compounds were confirmed by some spectroscopic techniques such as FT-IR, 1H NMR, 13C NMR, UV-Vis, and mass. The axially substitution increased the solubility of the silicon(IV) phthalocyanines. The prepared silicon(IV) phthalocyanines showed great results achieved from photochem. and photophys. investigations in DMSO solution Especially, high singlet oxygen and the fluorescence quantum yield values of the quaternized silicon (IV) phthalocyanines indicates that these compounds have major potential as photosensitizers in PDT. Furthermore, studied silicon(IV) phthalocyanine complexes could be classified as the stable photosensitizer in accordance with photodegradation study results. The fluorescence quenching behavior of these phthalocyanine complexes was also examined using fluorescence quenching method by 1,4-benzoquinone (BQ).

Star-shaped polymers have unique phys. properties and they are sought after materials in industry. However, the ease of synthesis is essential for translation of these materials into large-scale applications. Herein, a highly efficient synthetic method to prepare star-shaped polymers by combination of Cu-mediated reversible deactivation radical polymerization (Cu-RDRP) and thiol-bromo click reaction is described. Well-defined linear and block polymers with a very high bromine chain end fidelity are obtained via Cu-RDRP and subsequently react with multi-functional thiol compounds High coupling efficiencies of larger than 90% are obtained owing to the quick and efficient reaction between thiols and alkyl bromides. Moreover, the arms of the obtained star-shaped polymers are linked via thioether bonds to the core, making them susceptible for oxidative degradation

Myeloid cell leukemia 1 (MCL-1) is a BCL-2 family protein that has been implicated in the progression and survival of multiple tumor types. Herein the authors report a series of MCL-1 inhibitors that emanated from a high throughput screening (HTS) hit and progressed via iterative cycles of structure-guided design. Advanced compounds from this series exhibited subnanomolar affinity for MCL-1 and excellent selectivity over other BCL-2 family proteins as well as multiple kinases and GPCRs. In a MCL-1 dependent human tumor cell line, administration of compound I rapidly induced caspase activation with associated loss in cell viability. The small mols. described herein thus comprise effective tools for studying MCL-1 biol.

Category: oxazolidine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, is researched, Molecular C12H16N2O2, CAS is 67914-60-7, about 18F-Deoxyfluorination of Phenols via Ru π-Complexes. Author is Beyzavi, Hudson; Mandal, Debashis; Strebl, Martin G.; Neumann, Constanze N.; D’Amato, Erica M.; Chen, Junting; Hooker, Jacob M.; Ritter, Tobias.

The deficiency of robust and practical methods for 18F-radiofluorination is a bottleneck for positron emission tomog. (PET) tracer development. Here, we report the first transition-metal-assisted 18F-deoxyfluorination of phenols. The transformation benefits from readily available phenols as starting materials, tolerance of moisture and ambient atm., large substrate scope, and translatability to generate doses appropriate for PET imaging.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, is researched, Molecular C12H16N2O2, CAS is 67914-60-7, about Tetra-(acetyl piperazine phenoxy) phthalocyaninato zinc complexes and their proteins conjugates: synthesis, characterisation and photodynamic activities, the main research direction is tetra acetyl piperazine phenoxy phthalocyaninato zinc protein conjugate photodynamic.Category: oxazolidine.

Two zinc phthalocyanines, tetra-α-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn) and tetra-β-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn), have been synthesized and characterized with 1H NMR, MS, IR and elemental anal. The electronic absorption spectra of two complexes in common organic solvents (N,N-DMF, THF, n-octanol) were typical for nonaggregated phthalocyanines, showing a Q band at 693∼698 nm for 1 and 681 ∼ 682 nm for 2. This indicates that the Q band of zinc phthalocyanine with the substituted groups located in the α position is largely red shifted than that in the β position. The spectral features of complexes 1 and 2 in aqueous media suggest the α-substituted groups are more effective than β-substituted groups to hinder the aggregation of phthalocyanine mol. The interactions between two complexes with serum albumin and transferrin (BSA, HSA and apoTf) were investigated by absorption and fluorescence spectroscopy. The binding constants were found to be (1 ∼ 20) × 105 mol-1·L. By comparison, β-substituted 2 had stronger combining ability with albumin than that of α-substituted 1. The non-covalent conjugates (1-BSA, 2-BSA, 1-HSA, 1-apoTf and 1-FeTf) with the molar ratio of about 1 : 1 have also been prepared The photodynamic activities of two complexes and their bioconjugates against MCF-7 mammary tumor cells were examined The result shows that the photocytotoxicities of conjugates are higher than that of complexes 1 ∼ 2 and follows the order 1-BSA > 1-FeTf > 1-HSA, 1-apoTf > 2-BSA > 1>2.

Photo-ATRP experiments confirmed controlled polymerization conditions using CuII at the ppm scale resulting in dispersities between 1.06 to 1.10. Chain end fidelity was successfully provided by chain extension and block copolymerization addnl. approving the living feature of polymerization using a CD synthesized from lac dye comprising olefinic moieties in the originating biomass. By global anal., time resolved fluorescence measurements indicated the appearance of several emitting species contributing to the reactivity of the excited states. Different cytotoxic response appeared following the answer of MCF-10A cells in a flow cytometry assay; that is 400μg mL-1.
