A series of novel quinoline-docetaxel analogs I (R = 2-quinolinylcarbonyl, 3-quinolinylcarbonyl, 1-isoquinolinylcarbonyl, 6-quinolinylcarbonyl, etc., R¹ = H, COMe) were designed and synthesized by introducing bioactive quinoline scaffold to C2′-OH of docetaxel. The anticancer activities of these novel analogs were investigated against different human cancer cell lines including Hela, A549, A2780, MCF-7 and two resistant strains A2780-MDR and MCF-7-MDR. The data showed these analogs possessed similar to better cytotoxicity than docetaxel. Compound I (R = 6-quinolinyl, R¹ = H) was found to be the most potent one, and its IC₅₀ value against MCF-7-MDR was 8.8 nM (IC₅₀ of docetaxel was 180 nM). This work indicated that the introduction of quinolyl group in docetaxel could enhance cytotoxicity and reduce drug-resistance.

In the presence of [Cp^*RhCl₂]₂ and AgSbF₆, perylenediimides underwent chemoselective and regioselective iodination with N-iodosuccinimide mediated by Cu(OAc)₂ in 1,2-dichloroethane to yield ortho-tetraiodination perylenediimides I [R = (BuCH₂CH₂)₂CH, Et₂CH] in 71-89% yields; the reactions were performed on multigram scale. Mono-, di-, and triiodinated perylenediimides were prepared chemoselectively by varying the reaction conditions and solvent. I [R = (BuCH₂CH₂)₂CH] underwent Suzuki and Sonogashira coupling reactions and substitution with aniline, thiophenol, and phenol to give tetrasubstituted perylenediimides; Sonogashira coupling with dialkynes yielded conjugated microporous polymers. The UV/visible spectra, fluorescence behavior, reduction potentials, and calculated HOMO and LUMO energies of I [R = (BuCH₂CH₂)₂CH] and its coupling products were determined The structure of I (R = Et₂CH) was determined by X-ray crystallog.

Construction of anisotropic fluorescent nanofibers assisted by electro-spinning and its optical sensing applications was written by Zhang, Fa-Heng;Jiang, Rui-Xue;Cao, Wei;Du, Bin;Cao, Ding-Yuan;Ding, Zhi-Jun;Li, Zhi-Jun. And the article was included in RSC Advances in 2019.Name: 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 This article mentions the following:

Fixing the gap between “nano-scaled” pieces and “product-scale” materials, devices or machines is an ineluctable challenge that people have to tackle. Herein, we show that combining self-assembly and electrospinning processes results in the fabrication of anisotropic fluorescent nanofibers (PDI@PVDF) in which the well-defined rod-like perylene bisimide derivative assemblies are embedded in a highly oriented way along the axis of the poly(vinylidene fluoride) (PVDF) fiber. Compared to fragile individual PDI assemblies, the electrospinning anisotropic fluorescent PDI@PVDF nanofibers not only maintain high sensitivity for aniline vapor but also exhibit an unexpected short response time for both quenching and recovering. The results demonstrate that electrospinning assistance is a versatile and effective strategy to maintain the anisotropy of fluorescent nanomaterials, building a bridge between self-assembled nano-rods and practical materials. 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: 110590-84-6Name: 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).

Solid-liquid slurries are vital and increasingly prevalent in the pharmaceutical and chem. industries. Despite the importance of these heterogeneous systems, process control and optimization are fundamentally hindered by a lack of compatible real-time anal. techniques. We present herein an online HPLC monitoring platform enabling access to real-time compositional information on slurries. We demonstrate the system by investigating the heterogeneous synthesis reaction of tetrabenazine. Furthermore, we integrated our online HPLC platform with the orthogonal monitoring techniques of a pH probe and a microscopic imaging probe to provide addnl. mechanistic insight. These combined insights enable the optimization of tetrabenazine synthesis in terms of reaction time, byproduct formation, and diastereomeric purity of the final product. In the experiment, the researchers used many compounds, for example, Tetrabenazine (+)- (cas: 1026016-83-0Computed Properties of C19H27NO3).

And the article was included in Bioorganic & Medicinal Chemistry Letters in 2015.Category: isoquinoline This article mentions the following:

An expansive set of N-aryl-N’-(3-(substituted)phenyl)-N’-(methyl)guanidine was prepared in a search for new leads to prospective PET ligands for imaging of the open channel of the N-methyl-D-aspartate (NMDA) receptor in vivo. The N-aryl rings and their substituents were varied, whereas the N-methyl-group was maintained as a site for potential labeling with the positron-emitter, carbon-11 (t_1/2 = 20.4 min). At micromolar concentration, over half of the prepared compounds strongly inhibited the binding of [³H]TCP to its binding site in the open NMDA receptor in vitro. Four ligands displayed affinities that are similar or superior to those of the promising SPECT radioligand ([¹²³I]CNS1261). The 3′-dimethylamine-derivative (K_i 36.7 nM), 3′-trifluoromethyl-derivative (K_i 18.3 nM) and 3′-methylthio-derivative (K_i 39.8 nM) of N-(1-naphthyl)-N’-(phenyl)-N’-(methyl)guanidine were identified as especially attractive leads for PET radioligand development. The synthesis of the target compounds was achieved using amines as reactants, such as 3-bromo-4-fluoro-N-(methyl)benzenamine, 1-naphthalenamine, 2-naphthalenamine, 1-isoquinolinamine, 5-isoquinolinamine, 8-quinolinamine and related substances [N-(methyl)arenamine] derivatives The title compounds thus formed included N-methyl-N-[3-(methylthio)phenyl]-N‘-(1-naphthalenyl)guanidine, N-methyl-N‘-(1-naphthalenyl)-N-[3-(trifluoromethyl)phenyl]guanidine, N-(4-fluoro-3-methylphenyl)-N-methyl-N‘-(-naphthalenyl)guanidine.
