Hauke, Tobias J.;Hoefner, Georg;Wanner, Klaus T. research published 《 Generation and screening of pseudostatic hydrazone libraries derived from 5-substituted nipecotic acid derivatives at the GABA transporter mGAT4》, the research content is summarized as follows. The γ-aminobutyric acid (GABA) transporter mGAT4 represents a promising drug target for the treatment of epilepsy and other neurol. disorders; however, the lack of highly potent and selective inhibitors for mGAT4 still retards its pharmacol. elucidation. Herein, the generation and screening of pseudostatic combinatorial hydrazone libraries at the murine GABA transporter mGAT4 for the search of novel GABA uptake inhibitors is described. The hydrazone libraries contained more than 1100 compounds derived from nipecotic acid derivatives substituted at the 5-position instead, as common, at the 1-position of the core structure. Two hits were found and evaluated, which display potencies in the lower micromolar range at mGAT4 and its human equivalent hGAT3. These compounds possess a lipophilic moiety derived from a biphenyl residue attached to the 5-position of the hydrophilic nipecotic acid moiety via a three-atom spacer. Thus, the novel structures with potencies close to that of the bench mark mGAT4 inhibitor (S)-SNAP-5114 add new insights into the structure-activity relationship of mGAT4 inhibitors and could provide a promising starting point for the development of new mGAT4 inhibitors with even higher potencies.

A series of novel thiosemicarbazone derivatives I [R¹ = Ph, benzyl, phenylethyl,etc.; R² = 2-pyridyl, 3-methyl-2-pyridyl, 4-methyl-2-pyridyl,etc.; R³ = H, Me] containing indole fragment were designed and synthesized. Most compounds exhibited excellent antiproliferative activity against PC3, MGC803 and EC109 cell lines with low micromolar IC₅₀ (0.14-12μM). Especially, compound I [R¹ = 2-(5-chloro-1H-indol-3-yl)ethyl; R² = 5-methyl-2-pyridyl; R³ = H] can selectively inhibit PC3 cells in three tested tumor cells with IC₅₀ value of 0.14 μM, which was attributed to a synergistic effect after introducing indole fragment into the TSC structure. Meanwhile, compound I [R¹ = 2-(5-chloro-1H-indol-3-yl)ethyl; R² = 5-methyl-2-pyridyl; R³ = H] displayed more selectivity in PC3 cells toward two normal WPMY-1 and GES-1 cell lines, compared to those of 3-AP and DPC. It was also found that I [R¹ = 2-(5-chloro-1H-indol-3-yl)ethyl; R² = 5-methyl-2-pyridyl; R³ = H] can effectively inhibit PC3 cell proliferation, colonization and induce apoptosis. Compound I [R¹ = 2-(5-chloro-1H-indol-3-yl)ethyl; R² = 5-methyl-2-pyridyl; R³ = H] may significantly suppress migration and invasion by blocking the EMT process but had no effect on cell cycle. Collectively, this findings indicated that I [R¹ = 2-(5-chloro-1H-indol-3-yl)ethyl; R² = 5-methyl-2-pyridyl; R³ = H] with structure of thiosemicarbazone containing indole may serve as a useful anticancer lead for further optimization and development.

To discover novel anticancer agents with potent and low toxicity, a range of new thiosemicarbazone-indole analogs I [R = H, Me, Cl, OMe; R¹ = H, Me, R² = H, Me, OH, etc.; R³ = H, Me; X = N, C] based on lead compound II were designed and synthesized previously. Most compounds displayed moderate to high anticancer activities against five tested tumor cells (PC3, EC109, DU-145, MGC803, MCF-7). Specifically, the represented compound I [R = H, R¹ = Me; R² = Me, R³ = H] (III) possessed strong antiproliferative potency and high selectivity toward PC3 cells with the IC₅₀ value of 0.054μM, compared with normal WPMY-1 cells with the IC₅₀ value of 19.470μM. Preliminary mechanism research indicated that compound (III) could significantly suppress prostate cancer cells (PC3, DU-145) growth and colony formation in a dose-dependent manner. Besides, derivative (III) induced G1/S cycle arrest and apoptosis, which may be related to ROS accumulation due to the activation of MAPK signaling pathway. Furthermore, mol. (III) could effectively inhibit tumor growth through a xenograft model bearing PC3 cells and had no evident toxicity in vivo. Overall, based on the biol. activity evaluation, analog (III) can be viewed as a potential lead compound for further development of novel anti-prostate cancer drug.

Holloway, Lauren R.;Bogie, Paul M.;Lyon, Yana;Ngai, Courtney;Miller, Tabitha F.;Julian, Ryan R.;Hooley, Richard J. research published 《 Tandem Reactivity of a Self-Assembled Cage Catalyst with Endohedral Acid Groups》, the research content is summarized as follows. Self-assembly of a carboxylic acid-containing ligand into an Fe₄L₆ iminopyridine cage allows endohedral positioning of the acid groups while maintaining a robust cage structure. The cage is an effective supramol. catalyst, providing up to 1000-fold rate enhancement of acetal solvolysis. This enhanced reactivity allows a tandem deprotection/cage-to-cage interconversion that cannot be achieved with other acid catalysts. The combination of rate enhancements and sequestration of the reactive function confers both activity and selectivity on the process, mimicking enzymic behavior.

Giraldi, Erica;Scopelliti, Rosario;Fadaei-Tirani, Farzaneh;Severin, Kay research published 《 Metal-Stabilized Boronate Ester Cages》, the research content is summarized as follows. Mol. cages with arylboronate ester caps at the vertices are described. The cages were obtained by metal-templated polycondensation reactions of a tris(2-formylpyridine oxime) ligand with arylboronic acids. Suited templates are triflate or triflimide salts of Zn^II, Fe^II, Co^II, or Mn^II. In the products, the metal ions are coordinated internally to the pyridyl and oximato N atoms adjacent to the boronate ester, resulting in an improved hydrolytic stability of the latter. It is possible to decorate the cages with cyano or aldehyde groups using functionalized arylboronic acids. The aldehyde groups allow for a postsynthetic modification of the cages via an imine bond formation.

The encapsulation of an organic dye, 10-phenylphenothiazine (PTH), in the inner cavity of single-walled carbon nanotubes (SWNTs) as a breaking heterogenization strategy is presented. The PTH@oSWNT material was microscopically and spectroscopically characterized, showing intense photoemission when illuminated with visible light at the nanoscale. Thus, PTH@oSWNT was employed as a heterogeneous photocatalyst in single electron transfer dehalogenation reactions under visible light irradiation The material showed an enhanced photocatalytic activity, achieving turnover numbers as high as 3200, with complete recyclability and stability for more than eight cycles. Computational calculations confirm that electronic communication between both partners is established because, upon illumination, an electron of the excited PTH is transferred from the π system of the mol. to the delocalized π-cloud of the SWNT, thus justifying the enhanced photocatalytic activity.

In this work a new acceptor is used for use in thermally activated delayed fluorescence (TADF) emitters, pyridylbenzimidazole, which when coupled with phenoxazine allows efficient TADF to occur. N-functionalization of the benzimidazole using Me, Ph, and tert-Bu groups permits color tuning and suppression of aggregation-caused quenching (ACQ) with minimal impact on the TADF efficiency. The functionalized derivatives support a higher doping of 7 wt% before a fall-off in photoluminescence quantum yields is observed, in contrast with the parent compound, which undergoes ACQ at doping concentrations greater than 1 wt%. Complex conformational dynamics, reflected in the time-resolved decay profile, is found. The singlet-triplet energy gap, ΔE_ST, is modulated by N-substituents of the benzimidazole and ranges of between 0.22 and 0.32 eV in doped films. Vacuum-deposited organic light-emitting diodes, prepared using three of the four analogs, show maximum external quantum efficiencies, EQE_max, of 23.9%, 22.2%, and 18.6% for BIm(Me)PyPXZ, BIm(Ph)PyPXZ, and BImPyPXZ, resp., with a correlated and modest efficiency roll-off at 100 cd m^-2 of 19% 13%, and 24% of the EQE_max, resp.

A series of multinuclear lanthanide-covalent organic polyhedra (LnCOPs), including pillar-typed triangular prisms 1-Ln₃ and tetrahedra 2-Ln₄ (Ln = La^III, Sm^III, Eu^III), have been constructed for the first time, through either one-pot subcomponent self-assembly or post-assembly metalation. In contrast to the known tetrahedral cages based on transition metals, the pillar-typed polyhedra were favored from the same organic components in the presence of lanthanides. Besides this, facile transmetalations between the 1-Ln₃ polyhedra endow cascade chameleonic luminescence. Meanwhile, the open metal sites and pendent amine groups on 1-Ln₃ enable these polyhedra to catalyze the Henry reaction efficiently. A series of multinuclear lanthanide-covalent organic polyhedra (LnCOPs) have been synthesized, which demonstrate chameleonic luminescence by trans-metalation.

Histone lysine demethylase 4D (KDM4D) plays an important role in the regulation of tumorigenesis, progression and drug resistance and has been considered a potential target for cancer treatment. However, there is still a lack of potent and selective KDM4D inhibitors. In this investigation, we report a new class of KDM4D inhibitors containing the 2-(aryl(pyrrolidine-1-yl)methyl)phenol scaffold, identified through AlphaLisa-based screening, structural optimization, and structure-activity relationship analyses. Among these inhibitors, 24s (I) was the most potent, with an IC₅₀ value of 0.023 ± 0.004μM. This compound exhibited more than 1500-fold selectivity towards KDM4D vs. KDM4A as well as other JMJD subfamily members, indicating good selectivity for KDM4D. Kinetic anal. indicated that 24s did not occupy the 2-oxoglutarate binding pocket. In an in vitro assay, 24s significantly suppressed the proliferation and migration of colorectal cancer (CRC) cells. Overall, this study has identified a good tool compound to explore the biol. function of KDM4D and a good lead compound for drug discovery targeting KDM4D.

Feng, Tiantian;Streater, Daniel;Sun, Bing;Duisenova, Korlan;Wang, Dong;Liu, Yi;Huang, Jier;Zhang, Jian research published 《 Tuning Photoexcited Charge Transfer in Imine-Linked Two-Dimensional Covalent Organic Frameworks》, the research content is summarized as follows. The generation of a long-lived charge-separated state in versatile π-conjugated two-dimensional covalent organic frameworks (2D COFs), a process essential to extending their great potentials in advanced semiconducting applications, is yet fully elucidated. Herein, we report a systematic investigation of the photophys. properties of three highly crystalline imine-linked 2D COFs using steady-state and transient absorption spectroscopy accompanied by time-dependent d. functional theory (TDDFT) calculations The different electron affinity between 5,5′,5′′-(1,3,5-benzenetriyl)tris(2-pyridinecarboxaldehyde) (BTPA) and three tunable electron-donating/accepting triamine monomers dominated the formation of the excited-state, charge-transfer direction, and lifetime. A prominent charge transfer from electron-rich 4,4′,4′′-triaminotriphenylamine (TAPA) to BTPA in COF_TAPA-BTPA led to the long-lived charge-separated state, which was attributed to a greater degree of delocalization compared to the two other COFs. These results provide fundamental insight into the importance of structure-property correlation for designing advanced photoactive 2D COF materials with the efficient charge transfer and long-lived charge-separated state.
