Formation of a long-lived charge-separated state of a zinc phthalocyanine-perylenediimide dyad by complexation with magnesium ion was written by Fukuzumi, Shunichi;Ohkubo, Kei;Ortiz, Javier;Gutierrez, Ana M.;Fernandez-Lazaro, Fernando;Sastre-Santos, Angela. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2005.Formula: C50H62N2O4 This article mentions the following:

Photoexcitation of a zinc phthalocyanine-perylenediimide (ZnPc-PDI) dyad affords the triplet excited state without the fluorescence emission, whereas addition of Mg²⁺ to the photoexcited ZnPc-PDI results in formation of a long-lived charge-separated state (ZnPc^•+-PDI^•-/Mg²⁺) in which PDI^•- forms a complex with Mg²⁺. In the experiment, the researchers used many compounds, for example, 2,9-Di(tridecan-7-yl)anthra[2,1,9-def:6,5,10-d’e’f’]diisoquinoline-1,3,8,10(2H,9H)-tetraone (cas: 110590-84-6Formula: C50H62N2O4).

Human serum albumin (HSA) is an important carrier protein in plasma with various functions, and it is exposed to glycation. Alkaloids are diverse compounds that have showed different anti-glycation activities. The present study aimed to investigate the anti-glycation activity of thirty alkaloid compounds First, the compounds were studied via Lipinski′s rule; then, among thirty alkaloids, twenty-three were further designated for docking study, using AutoDock program. Three compounds which provided the min. docking score were selected for further assays. Jatrorrhizine displayed potential activity to inhibit the HSA glycation. The stability of the jatrorrhizine-HSA complex was confirmed by mol. dynamics simulation (MDs). To approve the efficacy of this compound, future in vitro and in vivo studies are required.

Thermal and Mechanochemical Syntheses of Luminescent Mononuclear Copper(I) Complexes was written by Liang, Panyi;Kobayashi, Atsushi;Hasegawa, Tatsuya;Yoshida, Masaki;Kato, Masako. And the article was included in European Journal of Inorganic Chemistry in 2017.Name: 5-Nitroisoquinoline This article mentions the following:

Mononuclear Cu^I iodide complexes, [CuI(PPh₃)₂L] {PPh₃ = PPh₃; L = 4-aminoisoquinoline (4-aiq) 2, 5-aminoisoquinoline (5-aiq) 3, and 5-nitroisoquinoline (niq) 4}, were prepared by three different methods: normally used reactions in the solution state, mechanochem. synthesis, and newly developed solvent-free thermal synthesis. Although no solvent was required for the mechanochem. synthesis of the parent complex [CuI(PPh₃)₂(iq)] (1; iq = isoquinoline), a minimal amount of assisting solvent (PhCN) was required for the mechanochem. syntheses of the three functionalized isoquinoline complexes. The amino-functionalized isoquinoline complexes were successfully synthesized by heating the ground mixture of three types of starting materials at ∼100°, where the PPh₃ ligand melted to promote complex formation by acting as the ligand and the solvent. The emission properties strongly depend on the L ligand: Complexes 2 and 3 showed vibronic emission spectra originating from the ³ππ^* excited state localized on the L ligand, whereas complex 4 did not show any emission in the visible region. In the experiment, the researchers used many compounds, for example, 5-Nitroisoquinoline (cas: 607-32-9Name: 5-Nitroisoquinoline).

5-Nitroisoquinoline (cas: 607-32-9) belongs to isoquinoline derivatives. Quinoline is a mancude organic heterobicyclic parent, an azaarene, an ortho-fused heteroarene and a member of isoquinolines.

Water soluble bis(indolenine)squaraine salts for use as fluorescent protein-sensitive probes was written by Lynch, Daniel E.;Chowdhury, Mohammed Z. H.;Luu, Nhat-Linh;Wane, Elizabeth S.;Heptinstall, John;Cox, Martin J.. And the article was included in Dyes and Pigments in 2013.Computed Properties of C9H6N2O2 This article mentions the following:

Water soluble fluorescent squaraine dyes can be produced as organic salts in combination with a range of organic cations although some cations, it was found, limit solubility Chem. anal. of twenty-four such squaraine salts showed that only one existed in the solid-state as the pure organic salt, all others existed as hydrates with varying amounts of crystalline water, except for one that existed as a butanol solvate. Five of the twenty-four (primarily nitro-substituted cations) existed as mono-cation/sulfonic acid salts, as opposed to the bis-cationic salt state that was expected for all. Preliminary fluorescence results indicated that the increase in fluorescence verses increase of protein (bovine serum albumin) concentration was significantly hindered if the protein was stored in a phosphate buffer. Comparative experiments undertaken with the protein dissolved in water showed substantial differences in the rate of increase of fluorescence with increasing protein concentration The largest rate of change came from the morpholinium salt. It is suggested that this is because morpholine hinders neither the hydrophobic docking of the squaraine group into the protein nor the fluorescence generation within the squaraine mol. In the experiment, the researchers used many compounds, for example, 5-Nitroisoquinoline (cas: 607-32-9Computed Properties of C9H6N2O2).

Direct Conversion of 1-(2-Bromobenzoyl)isoquinolines to Dibenzo[de,g]quinolin-7-ones via Reductive Photocyclization was written by Chuang, Ta-Hsien;Li, Chien-Fu;Lee, Hong-Zin;Wen, Yu-Chia. And the article was included in Journal of Organic Chemistry in 2013.Formula: C9H7NO This article mentions the following:

A series of A/D-ring substituted dibenzo[de,g]quinolin-7-ones I (R¹ – R⁴ = H, MeO; R²R³ = OCH₂O; R⁵ = H, MeO, CF₃; R⁴R⁵ = OCH₂O) was produced from the corresponding isoquinolinones II and (2-bromophenyl)acetonitriles III in four steps. This represents a convenient approach toward the synthesis of tetracyclic alkaloids. A direct conversion of 1-(2-bromobenzoyl)isoquinolines IV to dibenzo[de,g]quinolin-7-ones I is the key step in the total synthesis. The yield of the reductive photocyclization depends on the position of the substituents at the isoquinolyl ring and the Ph group. The mechanism of the reductive photocyclization is also discussed. In the experiment, the researchers used many compounds, for example, 1-Hydroxyisoquinoline (cas: 491-30-5Formula: C9H7NO).
