Avibactam is a non-β-lactam based second generation β-lactamase inhibitor containing diazabicyclooctane (DBO) ring as β-lactam mimic. The C2 position of DBO scaffold was substituted by a number of amidine derivatives to form water soluble final compounds I [R¹ = CH₂NH₂, 4-thiazolyl, cyclohexylmethyl, 3-pyridylmethyl, etc.]. The synthesized compounds were evaluated for their antibacterial and synergistic activity in combination with an antibiotic in vitro. The compounds, were tested against ten bacterial strains alone and in combination with existing antibiotic, meropenem. All compounds didn’t showed antibacterial activity when alone (MIC, >128μM), however exhibited moderate to good synergistic activity in presence of meropenem by lowering its MIC values. Compound I [R¹ = (4-methylpiperazin-1-yl)methyl] proved most potent among other counterparts against all bacterial species with MIC from <0.29μM to 2.34μM, and showed comparable or improved activity to avibactam against eight bacterial strains. Compound I [R¹ = (4-methylpiperazin-1-yl)methyl] may prove a lead for next level in vivo and clin. studies.

Gao, Yaowen;Zhu, Yue;Li, Tong;Chen, Zhenhuan;Jiang, Qike;Zhao, Zhiyu;Liang, Xiaoying;Hu, Chun research published 《 Unraveling the high-activity origin of single-atom iron catalysts for organic pollutant oxidation via peroxymonosulfate activation》, the research content is summarized as follows. Single-atom catalysts (SACs) have emerged as efficient materials in the elimination of aqueous organic contaminants; however, the origin of high activity of SACs still remains elusive. Herein, we identify an 8.1-fold catalytic specific activity (reaction rate constant normalized to catalyst’s sp. surface area and dosage) enhancement that can be fulfilled with a single-atom iron catalyst (SA-Fe-NC) prepared via a cascade anchoring method compared to the iron nanoparticle-loaded catalyst, resulting in one of the most active currently known catalysts in peroxymonosulfate (PMS) conversion for organic pollutant oxidation Exptl. data and theor. results unraveled that the high-activity origin of the SA-Fe-NC stems from the Fe-pyridinic N₄ moiety, which dramatically increases active sites by not only creating the electron-rich Fe single atom as the catalytic site but also producing electron-poor carbon atoms neighboring pyridinic N as binding sites for PMS activation including synchronous PMS reduction and oxidation together with dissolved oxygen reduction Moreover, the SA-Fe-NC exhibits excellent stability and applicability to realistic industrial wastewater remediation. This work offers a novel yet reasonable interpretation for why a small amount of iron in the SA-Fe-NC can deliver extremely superior specific activity in PMS activation and develops a promising catalytic oxidation system toward actual environmental cleanup.

Gao, Yaowen;Zhu, Yue;Chen, Zhenhuan;Hu, Chun research published 《 Nitrogen-Coordinated Cobalt Embedded in a Hollow Carbon Polyhedron for Superior Catalytic Oxidation of Organic Contaminants with Peroxymonosulfate》, the research content is summarized as follows. The search for high-active and long-lasting materials is of paramount significance for elimination of aqueous organic contaminants. Herein, a nitrogen-coordinated cobalt embedded in hollow carbon polyhedron (marked as NCoHCP) has been synthesized by thermal transformation of core-shell-architectured ZIF-8@ZIF-67. XPS, X-ray absorption spectroscopy (XAS), and theor. calculations confirmed the coordination of a Co atom with one N atom in NCoHCP. The resultant NCoHCP catalyst delivers extremely superior catalytic performance in peroxymonosulfate (PMS) decomposition into active species toward complete oxidation of organic pollutants in less than 45 s. Exptl. data and theor. computations disclosed the formation of Co-pyridinic N moiety not only creates the Co species with higher electron d. as active sites but also increases the C atom neighboring pyridinic N with lower electron d. as binding sites for PMS conversion toward reactive oxygen species generation to oxidize organic pollutant. On the other hand, the donation of electron from organic contaminant toward the C atom adjacent to pyridinic N also induces organic contaminant oxidation The dual-pathway degradation contributes to superior catalytic oxidation of organics over NCoHCP. This study furnishes an effective strategy for developing high-performance and robust metal/carbon hybrid materials toward wide environmental applications.

Fang, Cunxia;Gao, Xingmin;Zhang, Xiangcheng;Zhu, Jiahui;Sun, Sheng-Peng;Wang, Xiaoning;Wu, Winston Duo;Wu, Zhangxiong research published 《 Facile synthesis of alkaline-earth metal manganites for the efficient degradation of phenolic compounds via catalytic ozonation and evaluation of the reaction mechanism》, the research content is summarized as follows. In this paper, we demonstrate the facile and general synthesis of alk.-earth metal manganites, denoted as A(Mg, Ca, Ba)Mn_xO_y, for efficient degradation of high-concentration phenolic compounds via catalytic ozonation. The representative CaMn_xO_y oxides show a hierarchical spherical structure constructed by crystalline nanorods and numerous macropores. They possess mixed Mn⁴⁺/Mn³⁺ chem. valences and abundant surface hydroxyl (OH) groups. The ozone (O₃) decomposition rate on the CaMn_xO_y catalysts is greatly accelerated and follows the first-order law. These catalysts are promising for the degradation of phenolic compounds via catalytic ozonation, exhibiting rapid pseudofirst-order degradation kinetics, a high total organic carbon (TOC) removal efficiency and an excellent stability. Under optimized conditions (a low O₃ dosage of 1.5 mg/min and a catalyst dosage of 7.5 g/L), for the treatment of concentrated phenol (50-240 mg/L), the CaMn_xO_y catalysts show 100% degradation and 50-70% mineralization within 1.0 h. The Ca²⁺ ions are essential to create redox Mn⁴⁺/Mn³⁺ couples and to significantly reduce manganese leaching. High surface ratios of Mn⁴⁺/Mn³⁺ and OH/lattice oxygen (O_lat) are beneficial for enhancing the catalytic performance. Superoxide anion free radicals (^·O^–₂) and singlet oxygen (¹O₂) are the predominant reactive species for the oxidation degradation The ^·O^–₂ reaction pathway is proposed. Specifically, the surface OH sites activate O₃, displaying highly enhanced decomposition rates. The generated ^·O^–₂ and ¹O₂ play a role in oxidation The redox Mn⁴⁺/Mn³⁺ and the O_lat/oxygen vacancy (O_lat/O_vac) couples play important roles in electron transfer. The proposed mechanism is supported by active site probing, radical scavenging, spectroscopic studies, and the results in the degradation of substituted phenols.

Eysseric, Emmanuel;Gagnon, Christian;Segura, Pedro A. research published 《 Identifying congeners and transformation products of organic contaminants within complex chemical mixtures in impacted surface waters with a top-down non-targeted screening workflow》, the research content is summarized as follows. Over 350,000 compounds are registered for production and use including a high number of congeners found in complex chem. mixtures (CCMs). With such a high number of chems. being released in the environment and degraded into transformation products (TPs), the challenge of identifying contaminants by non-targeted screening (NTS) is massive. “Bottom-up” studies, where compounds are subjected to conditions simulating environmental degradation to identify new TPs, are time consuming and cannot be relied upon to study the TPs of hundreds of thousands of compounds Therefore, the development of “top-down” workflows, where the structural elucidation of unknown compounds is carried directly on the sample, is of interest. In this study, a top-down NTS workflow was developed using mol. networking and clustering (MNC). A total of 438 compounds were identified including 176 congeners of consumer product additives and 106 TPs. Reference standards were used to confirm the identification of 53 contaminants among them lesser-known pharmaceuticals (aliskiren, sitagliptin) and consumer product additives (lauramidopropyl betaine, 2,2,4-trimethyl-1,2-dihydroquinoline). The MNC tools allowed to group similar TPs and congeners together. As such, several previously unknown TPs of pesticides (metolachlor) and pharmaceuticals (gliclazide, irbesartan) were identified as tentative candidates or probable structures. Moreover, some congeners that had no entry on global repositories (PubChem, ChemSpider) were identified as probable structures. The workflow worked efficiently with oligomers containing ethylene oxide moieties, and with TPs structurally related to their parent compounds The top-down approach shown in this study addresses several issues with the identification of congeners of industrial compounds from CCMs. Furthermore, it allows elucidating the structure of TPs directly from samples without relying on bottom-up studies under conditions discussed herein. The top-down workflow and the MNC tools show great potential for data mining and retrospective anal. of previous NTS studies.

Two novel series of 4-alkoxy-2-arylquinolines I (n = 1, 2; R = pyrrolidino, 4-hydroxypiperidino, piperidino, morpholino; X = Cl, CF₃) were designed and synthesized based on SARs of the reported TOP1 inhibitors and structural features required for stabilization of TOP1-DNA cleavage complexes (TOP1ccs). The in vitro anticancer activity of these two series of compounds was evaluated at one dose level using NCI-60 cancer cell lines panel. Compounds with p-substituted Ph at C2 and Pr linker at C4, were the most potent and were selected for assay at five doses level in which they exhibited potent anticancer activity at sub-micromolar level against diverse cancer cell lines. Compound I (Ar = 4-F₃CC₆H₄, 2-furyl, 2-thienyl, etc.; n = 2; R = pyrrolidino) was the most potent with full panel GI₅₀ MG-MID 1.26μM and the most sensitive cancers were colon cancer, leukemia and melanoma. Melanoma (LOX IMVI) was the most sensitive cell line to all tested compounds displaying GI₅₀ and LC₅₀ at sub-micromolar concentration against almost of the tested compounds Few compounds were assayed using TOP1-mediated DNA cleavage assay to evaluate their ability to stabilize TOP1ccs resulting in cancer cell death.
