Marine-originated spirocyclic bromotyrosines are considered as promising scaffolds for new anticancer drugs. In a continuation of research to develop potent and more selective anticancer compounds, authors synthesized a library of 32 spirocyclic clavatadine analogs by replacing the agmatine, i.e., 4-(aminobutyl)guanidine, side chain with different substituents. These compounds were tested for cytotoxicity against skin cancer using the human melanoma cell line (A-375) and normal human skin fibroblast cell line (Hs27). The highest cytotoxicity against the A-375 cell line was observed for dichloro compound I (CC₅₀ 0.4 ± 0.3μM, selectivity index (SI) 2). The variation of selectivity ranged from SI 0.4 to reach 2.4 for the pyridin-2-yl derivative II and hydrazide analog of 2-picoline III. The structure-activity relationships of the compounds in respect to cytotoxicity and selectivity toward cancer cell lines are discussed.

Peng, Wei;Liu, Jie;Li, Chenxu;Zong, Fuxing;Xu, Wensi;Zhang, Xing;Fang, Zhendong research published 《 A multipath peroxymonosulfate activation process over supported by magnetic CuO-Fe₃O₄ nanoparticles for efficient degradation of 4-chlorophenol》, the research content is summarized as follows. Heterogeneous catalysts with low cost, environmentally friendly, highly effective and ready separation from aqueous solution are highly desirable. Magnetic CuO-Fe₃O₄ nanoparticles, a type of non-toxic bimetallic transition metal oxide, is a promising heterogeneous catalyst for activation of peroxymonosulfate (PMS) to generate reactive oxygen species (ROS) that has not been previously investigated. In this study, the activation of PMS by CuO-Fe₃O₄ nanoparticles was evaluated using the degradation of 4-chlorophenol as a model reaction. Several critical factors such as pH, catalyst dosage and PMS concentration were investigated. CuO-Fe₃O₄/PMS system demonstrated a wide effective pH range to degrade 4-chlorophenol, namely 5.5 to 9.5. With the increase of the catalyst dosage, the degradation efficiency of 4-chlorophenol appeared to increase first and then decrease, that the inflection point was 0.5 g/L. Elevated PMS concentration obviously improved the decomposition of 4-chlorophenol; however, the plateau was reached when the PMS concentration was 8 mM. Further increase in PMS concentration would not significantly improve the removal efficiency. Through examining the effects of scavengers and ESR (ESR) analyses, CuO-Fe₃O₄ nanoparticles were proven to activate PMS through a non-radical and radical pathway to generate singlet oxygen, sulfate radicals and hydroxyl radicals.

A.;Verhoog, Stefan;Gantert, Liza;Lohith, Talakad G.;Schmitz, Alexander;Lee, Hsiaoju S.;Hesk, David;Hostetler, Eric D.;Davies, Ian W.;MacMillan, David W. C. research published 《 Metallaphotoredox aryl and alkyl radiomethylation for PET ligand discovery》, the research content is summarized as follows. Positron emission tomog. (PET) radioligands (radioactively labeled tracer compounds) are extremely useful for in vivo characterization of central nervous system drug candidates, neurodegenerative diseases and numerous oncol. targets¹. Both tritium and carbon-11 radioisotopologues are generally necessary for in vitro and in vivo characterization of radioligands², yet there exist few radiolabelling protocols for the synthesis of either, inhibiting the development of PET radioligands. The synthesis of such radioligands also needs to be very rapid owing to the short half-life of carbon-11. Here we report a versatile and rapid metallaphotoredox-catalyzed method for late-stage installation of both tritium and carbon-11 into the desired compounds via methylation of pharmaceutical precursors bearing aryl and alkyl bromides. Me groups are among the most prevalent structural elements found in bioactive mols., and so this synthetic approach simplifies the discovery of radioligands. To demonstrate the breadth of applicability of this technique, we perform rapid synthesis of 20 tritiated and 10 carbon-11-labeled complex pharmaceuticals and PET radioligands, including a one-step radiosynthesis of the clin. used compounds [¹¹C]UCB-J and [¹¹C]PHNO. We further outline the direct utility of this protocol for preclin. PET imaging and its translation to automated radiosynthesis for routine radiotracer production in human clin. imaging. We also demonstrate this protocol for the installation of other diverse and pharmaceutically useful isotopes, including carbon-14, carbon-13 and deuterium.

Piticari, Amalia-Sofia;Antermite, Daniele;Higham, Joe I.;Moore, J. Harry;Webster, Matthew P.;Bull, James A. research published 《 Stereoselective Palladium-Catalyzed C(sp³)-H Mono-Arylation of Piperidines and Tetrahydropyrans with a C(4) Directing Group》, the research content is summarized as follows. A selective Pd-catalyzed C(3)-H cis-functionalization of piperidine and tetrahydropyran carboxylic acids is achieved using a C(4) aminoquinoline amide auxiliary. High mono- and cis-selectivity is attained by using mesityl carboxylic acid as an additive. Conditions are developed with significantly lower reaction temperatures (≤50°C) than other reported heterocycle C(sp³)-H functionalization reactions, which is facilitated by a DoE optimization. A one-pot C-H functionalization-epimerization procedure provides the trans-3,4-disubstituted isomers directly. Divergent aminoquinoline removal is accomplished with the installation of carboxylic acid, alc., amide and nitrile functional groups. Overall, fragment compounds suitable for screening are generated in 3-4 steps from readily-available heterocyclic carboxylic acids.

Liu, Yani;Luo, Jun;Tang, Lin;Feng, Chengyang;Wang, Jiajia;Deng, Yaocheng;Liu, Haoyu;Yu, Jiangfang;Feng, Haopeng;Wang, Jingjing research published 《 Origin of the enhanced reusability and electron transfer of the carbon-coated Mn₃O₄ nanocube for persulfate activation》, the research content is summarized as follows. Manganese oxides and carbon materials are both desirable catalysts for persulfate (PS) advanced oxidation processes in environmental remediation. Nevertheless, manganese oxides suffer from low reusability while carbon materials face the problem of limited catalytic efficiency. For the purpose of making full use of the advantages of the two materials as well as avoiding their shortcomings, carbon-coated Mn₃O₄ composites (Mn₃O₄/C) with a regular nanocube structure were designed to activate PS for the removal of organics, and the catalytic processes were deeply investigated. The catalyst prepared at 400°C with a precursor ratio (glucose/KMnO₄) of 0.5 exhibited the best catalytic performance along with satisfactory reusability owing to the protection of the outer carbon layer. According to exptl. results and d. functional theory calculation, there were van der Waals interaction and a part of the strong attraction between the interface of PS and Mn₃O₄/C, which could be enhanced by inner Mn₃O₄ and thus promoted the electron transfer between PS and carbon shell, and the defective edges of the carbon layer with hydroxyl (C-OH) groups could act as active sites for PS activation. Radical (SO₄^•-, ^•OH) and nonradical (¹O₂) oxidation processes both participated in the degradation of 2,4-dichlorophenol, in which ^•OH was dominating. This study not only proposed a promising catalyst for the degradation of pollutants but also expanded research ideas for future PS activation mechanism studies by integrating the experiment and simulation.

Genetic depletion of cyclin-dependent kinase 12 (CDK12) or selective inhibition of an analog-sensitive CDK12 reduces DNA damage repair gene expression, but selective inhibition of endogenous CDK12 is difficult. Here, we report the development of MFH290(I), a novel cysteine (Cys)-directed covalent inhibitor of CDK12/13. MFH290 forms a covalent bond with Cys-1039 of CDK12, exhibits excellent kinome selectivity, inhibits the phosphorylation of serine-2 in the C-terminal domain (CTD) of RNA-polymerase II (Pol II), and reduces the expression of key DNA damage repair genes. Importantly, these effects were demonstrated to be CDK12-dependent as mutation of Cys-1039 rendered the kinase refractory to MFH290 and restored Pol II CTD phosphorylation and DNA damage repair gene expression. Consistent with its effect on DNA damage repair gene expression, MFH290 augments the antiproliferative effect of the PARP inhibitor olaparib.

Luo, Haopeng;Zhou, Xin;Chen, Quanyuan;Zhou, Juan research published 《 Removal of 2,4-dichlorophenoxyacetic acid by the boron-nitrogen co-doped carbon nanotubes: Insights into peroxymonosulfate adsorption and activation》, the research content is summarized as follows. B, N co-doped CNTs were synthesized by a simple one-step thermal process and the advanced oxidation processes (AOPs) of 2,4-dichlorophenoxyacetic acid (2,4-D) over the catalyst involved peroxymonosulfate (PMS) activation was investigated. The co-doped catalysts showed higher isoelec. points (IEPs) than those of CNTs and single doped CNTs, facilitating the adsorption of PMS anion (HSO-5) on the catalyst surface, and the AOPs of 2,4-D depended on PMS concentration could be illustrated by the Langmuir-Hinshelwood model. The removal efficiency of 2,4-D over CNTs, CB450, CN450 and CBN450-2 was 20%, 23%, 34% and 68%, resp. The enhancement of catalytic activity was due to the synergistic effect between B and N dopants and both the pyrrolic N and B-N complex played roles in the catalytic reaction. The quenching test and ESR (EPR) results showed that 1O₂ contributed most to the oxidation of 2,4-D and the reaction experienced both the free radical and non-radical pathways. Addnl., the DFT calculation results showed that the adsorption energy of PMS on the surface N dopants decreased by B co-doping, implying that a moderate adsorption energy may facilitate the release of active species generated by PMS activation.
