In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Phthalocyanines and Tetrapyrazinoporphyrazines with Two Cationic Donuts: High Photodynamic Activity as a Result of Rigid Spatial Arrangement of Peripheral Substituents, published in 2017-07-27, which mentions a compound: 56413-95-7, mainly applied to preparation phthalocyanine tetrapyrazino porphyrazine PDT cancer, Application of 56413-95-7.

High photodynamic activity was observed for hexadeca-cationic zinc, magnesium, and metal-free phthalocyanines (Pcs) and tetrapyrazinoporphyrazines with EC50 values as low as 5 nM (MCF-7 cells) for the best compound; this activity was several times better than that of clin. established photosensitizers verteporfin, temoporfin, S3AlOHPc, or protoporphyrin IX. This lead compound was characterized by low dark toxicity (TC50 = 369 μM), high efficiency against other cell lines (HCT 116 and HeLa), and possible activation by light above 680 nm. The excellent photodynamic activity resulted from the rigid spatial arrangement of the quaternized triazole moieties above and below the Pc core, as confirmed by X-ray crystallog. The triazole moieties thus formed two “”cationic donuts”” that protected the hydrophobic core against aggregation in water. The lysosomes were found to be the site of subcellular localization and were consequently the primary targets of photodynamic injury, resulting in predominantly necrotic cell death.

Different reactions of this compound(5,6-Dichloropyrazine-2,3-dicarbonitrile)Application of 56413-95-7 require different conditions, so the reaction conditions are very important.

Zn phthalocyanines and corresponding aza-analog azaphthalocyanines substituted with peripheral 2,6-diisopropylphenoxy substituents containing different functional groups (Br, OCH3, and OH) were synthesized and their photophys. properties were studied. UV-visible and 1H NMR analyses confirmed the nonaggregation behavior of the prepared complexes in most organic solvents. All studied compounds showed good photophys. and photochem. properties in THF and DMF with ΦF values at 0.22-0.44 and ΦΔ values ranging between 0.42 and 0.57. Hydroxylated compounds showed good solubility in polar solvents including EtOH, MeOH, acetone and even in aqueous EtOH mixtures Absorption spectra in aqueous EtOH indicated presence of only monomers even at very low EtOH content in H2O (0.5% of EtOH in H2O). Despite this, no fluorescence occurred from ∼50% of EtOH in H2O suggesting presence of aggregates that do not differ from monomers in a shape of absorption spectra.

The article 《Dually directional glycosylated phthalocyanines as extracellular red-emitting fluorescent probes》 in relation to this compound, is published in Dalton Transactions. Let’s take a look at the latest research on this compound (cas:56413-95-7).

The development of new non-aggregated phthalocyanines bearing multivalent saccharide moieties on their macrocyclic rims is of great interest. Many characteristics, including water-solubility, non-toxicity and others, can be feasibly obtained by these amphiphiles which can be considered as a key solution for demonstrating highly efficient photoactive materials in water. Herein, a family of five newly prepared dually directional Zn(II) containing phthalocyanines (PcG1-4) and azaphthalocyanine (AzaPcG1) glycoconjugates is described. The unique spatial arrangement of the glucoside units based on peripherally hexadeca-(PcG1) and nonperipherally octa-(PcG4) macrocycles provides a fully monomeric behavior along with a high fluorescence (ΦF ~0.21) in aqueous solution These amphiphiles were characterized by low toxicity, and an extremely low cellular uptake was obtained due to the highly polar nature of the glucoside substituents. Accordingly, their potential as suitable photoactive chromophores for red-emitting extracellular fluorescent probes has been confirmed upon the evaluation of paracellular transport using a layer of MDCKII cells with the permeability coefficient fully comparable with an established evaluator of the integrity of the monolayer.

A series of electron-accepting azaacene-type materials with different kinds and degrees of intermol. interactions were synthesized. Simple modification of the terminal substituents significantly modulated the photophys. and electrochem. properties. The degree of the weak intermol. interaction determined the emergence of a liquid crystalline (LC) phase for each compound Dipole-dipole interaction, π-π interaction and van der Waals interaction all contributed to stabilize the LC phase of I [R = C6H13, C12H25, C18H37] and II. The introduction of strong hydrogen bonding interaction enabled the formation of a highly ordered LC phase in III. Charge-transport properties of I, II and III were also investigated.

Optimal reaction conditions were developed for synthesis of octakis(butylamino), octakis(butylsulfanyl) and octakis(butoxy) azaphthalocyanines (AzaPc’s) with central metal Mg, Zn and metal-free. Their photodynamic activity was measured and compared as a dye-sensitized photooxidation of 1,3-diphenylisobenzofuran (DPBF). Compounds with alkylamino substituent are very poor producers of the singlet oxygen and therefore not suitable as sensitizers for photodynamic therapy (PDT). On the other hand, compounds with alkylsulfanyl and alkoxy substituents possess very good photodynamic activity and are suitable for PDT.

Unsym. tetrapyrazinoporphyrazines (TPyzPzs) from the group of azaphthalocyanines with one peripherally attached amino substituent (donor) were synthesized, and their photophys. properties (fluorescence quantum yield and singlet oxygen quantum yield) were determined The synthesized TPyzPzs were expected to undergo intramol. charge transfer (ICT) as the main pathway for deactivating their excited states. Several structural factors play a critical role in ICT efficiency. The substituent in the ortho position to the donor center significantly influences the ICT, with tert-butylsulfanyl and butoxy substituents inducing the strongest ICTs, whereas chloro, Me, Ph, and hydrogen substituents in this position reduce the efficiency. The strength of the donor pos. influences the ICT efficiency and correlates well with the oxidation potential of the amines used as the substituents on the TPyzPz as follows: n-butylamine < N,N-diethylamine < aniline < phenothiazine. The ICT (with conjugated donors and acceptors) in the TPyzPz also proved to be much stronger than a photoinduced electron transfer in which the donor and the acceptor are connected through an aliphatic linker.
