Dou, Jibo;Cheng, Jie;Lu, Zhijiang;Tian, Ziqi;Xu, Jianming;He, Yan research published 《 Biochar co-doped with nitrogen and boron switching the free radical based peroxydisulfate activation into the electron-transfer dominated nonradical process》, the research content is summarized as follows. In this study, N/B co-doped biochars were employed as metal-free activators of peroxydisulfate (PDS) for tetracycline degradation, more importantly, the roles of dopants and the relative contribution of radical vs nonradical oxidations were comprehensively investigated. Integrating with ESR and kinetics calculations, we showed that co-doping N and B into biochars not only boosted the catalytic activity but also switched the radical PDS-activated process into the electron transfer-dominated nonradical process. Compared with pristine biochar/PDS systems (22%), the nonradical contribution of N/B co-doped biochar/PDS systems increased to 59%, exhibiting outstanding stability and selectivity. Galvanic oxidation tests and theor. simulations unveiled that doped biochars as conductive tunnels accelerate the p.d.-driven electron transfer from the HOMO of pollutants to the LUMO of PDS due to the lower energy gap. This study provided new insights into the critical role of heteroatom-doped carbocatalysts in PDS nonradical activation.

Herein, a unique cascade reaction that enables the preparation of α-branched amines I (R = Me, Ad, oxan-4-ylmethyl, etc.; R¹ = H, Me, Ph; R² = Ph; R¹R² = -(CH₂)₂CH(Ph)(CH₂)₂-; R³ = H, Me; R⁴ = Ph, 4-chlorophenyl, furan-3-yl, etc.) and 3-methyl-1,2,2-triphenylpentan-1-amine bearing aryl or alkyl groups at the β- or γ-positions is reported. The cascade is initiated by reduction of redox active esters II to alkyl radicals. The resulting alkyl radicals are trapped by styrene derivatives, R¹C(R²)=CHR³ leading to benzylic radicals. The persistent 2-azaallyl radicals and benzylic radicals are proposed to undergo a radical-radical coupling leading to functionalized amine products I and 3-methyl-1,2,2-triphenylpentan-1-amine. Evidence is provided that the role of the nickel catalyst is to promote formation of the alkyl radical from the redox active ester and not promote the C-C bond formation. The synthetic method introduced herein tolerates a variety of imines III and redox active esters II, allowing for efficient construction of amine building blocks.

In recent decades, pharmacol. targeting of the autotaxin (ATX)/lysophosphatidic acid (LPA) axis accounted for excellent disease management benefits. Herein, to extend the scope of structure-activity relationships (SARs), fifteen indole-based carbamate derivatives I [R = 4-Me, 3,4-difluoro, 2,3-dichloro; R¹ = pyrrolidin-1-yl, (4-methyl-1-piperidyl), (4-methylpiperazin-1-yl); R² = H, CH₃, etc] were prepared to evaluate the ATX inhibitory potency. Among them, compound I [R = 3,5-dichloro; R¹ = morpholino; R² = H] bearing morpholine moiety was identified as the optimal ATX inhibitor (0.41 nM), superior to the pos. control GLPG1690 (2.90 nM). To resolve the intractable issue of poor pharmacokinetic (PK) property, urea moiety was introduced as a surrogate of carbamate which furnished compounds II [R³ = morpholino, (4-hydroxy-1-piperidyl), [2-(hydroxymethyl)pyrrolidin-1-yl]; R⁴ = H, 4-Cl, 4-F, etc]. The dedicated modification identified the diethanolamine entity II [R³ = [bis(2-hydroxyethyl)amino]; R⁴ = (3-chloro-4-methoxy-phenyl)] with satisfactory water solubility and PK profiles with a min. sacrifice of ATX inhibition (2.17 nM). The most promising candidate II [R³ = [bis(2-hydroxyethyl)amino]; R⁴ = (3-chloro-4-methoxy-phenyl)] was evaluated for anti-fibrosis effect in a bleomycin challenged mice lung fibrosis model. Upon treatment with II [R³ = [bis(2-hydroxyethyl)amino]; R⁴ = (3-chloro-4-methoxy-phenyl)], the in vivo ATX activity in both lung homogenate and broncheoalveolar fluid (BALF) sample was significantly down-regulated. Furthermore, the gene expression of pro-fibrotic cytokines transforming growth factor-β (TGF-β), interleukin- 6 (IL-6) and tumor necrosis factor-α (TNF-α) in lung tissue was reduced to normal level. Collectively, the promising biol. effects may advocate potential application of II [R³ = [bis(2-hydroxyethyl)amino]; R⁴ = (3-chloro-4-methoxy-phenyl)] in fibrosis relevant diseases.

Aiming to track the potential antitumor effect of novel allosteric autotaxin (ATX) inhibitors, a hybrid strategy was utilized by merging ATX inhibitors PF-8380 and GLPG1690, while the piperazinyl group in GLPG1690 was replaced with benzene ring to furnish imidazo[1,2-a]pyridine derivatives I [R¹ = 3,5-diCl, 4-CF₃, 3,4-di-F; R² = L-Prolinol, 4-hydroxyethylpiperazinyl, morpholine, etc.; R³ = CH₂, C(O); X = O, N]. Based on ATX enzymic assay, further changed the substituents within benzyl carbamate moiety and tuned the carbamate linker to urea group. Delightfully, compound I [R¹ = 3,5-diCl, R² = 4-hydroxyethylpiperazinyl] was identified as the optimal ATX inhibitor with an IC₅₀ value of 3.4 nM. Compound I [R¹ = 3,5-diCl, R² = 4-hydroxyethylpiperazinyl] exerted the most impressive antitumor effects, especially on Hep3B (0.58μM) and RAW264.7 (0.63μM) cell lines highly expressing ATX mRNA. Moreover, compound I [R¹ = 3,5-diCl, R² = 4-hydroxyethylpiperazinyl] could dose-dependently suppress the RAW264.7 cell migration rate in wound healing assay and significantly inhibit RAW264.7 cell colony formation. Meanwhile, compound I [R¹ = 3,5-diCl, R² = 4-hydroxyethylpiperazinyl] was capable of inducing weak to moderate apoptosis and achieved notable G2 phase arrest on RAW264.7 cells. Compound I [R¹ = 3,5-diCl, R² = 4-hydroxyethylpiperazinyl] may serve as a novel lead to probe possible role of ATX allosteric inhibitors in tumor diseases.

Defects and surface O functionalities of multi-walled C nanotubes (MWCNT) prepared by a solid state reaction were demonstrated as effective to activate peroxymonosulfate (PMS) for organic pollutant degradation The catalytic activity of defective, O-functionalized CNT (dCNT) was much better than bare CNT, due to many CNT surface active sites, including structural defects and carbonyl functional groups, and excellent elec. conductivity The effect of several operational factors and water conditions on the degradation rate of targeted pollutants and material stability were comprehensively evaluated for the practical application of the dCNT/PMS integrated process. The dCNT underlying catalytic mechanism is expected to occur by a non-radical pathway and radical-induced oxidation, where surface-bound radicals play a more dominant role than free radicals.

Human immunodeficiency virus-1 (HIV-1) is the causative agent of acquired immunodeficiency syndrome (AIDS). HIV-1, like all retroviruses, stably integrates its vDNA copy into host chromatin, a process allowing for permanent infection. This essential step for HIV-1 replication is catalyzed by viral integrase (IN) and aided by cellular protein LEDGF/p75. In addition, IN is also crucial for proper virion maturation as it interacts with the viral RNA genome to ensure encapsulation of ribonucleoprotein complexes within the protective capsid core. These key functions make IN an attractive target for the development of inhibitors with various mechanisms of action. We conducted a high-throughput screen (HTS) of ~370,000 compounds using a homogeneous time-resolved fluorescence-based assay capable of capturing diverse inhibitors targeting multifunctional IN. Our approach revealed chem. scaffolds containing diketo acid moieties similar to IN strand transfer inhibitors (INSTIs) as well as novel compounds distinct from all current IN inhibitors including INSTIs and allosteric integrase inhibitors (ALLINIs). Specifically, our HTS resulted in the discovery of compound I, with a novel IN inhibitor scaffold amenable for chem. modification. Its more potent derivative II similarly inhibited catalytic activities of WT and mutant INs containing archetypical INSTI- and ALLINI-derived resistant substitutions. Further SAR-based optimization resulted in compound III with an antiviral EC₅₀ of ~58μM and a selectivity index of >8500. Thus, our studies identified a novel small-mol. scaffold for inhibiting HIV-1 IN, which provides a promising platform for future development of potent antiviral agents to complement current HIV-1 therapies.

Dynamic covalent bonds (DCBs), which can undergo reversible cleavage and reformation upon exposure to readily useable stimuli, have attracted dramatic attention, but the library of such bonds still remains to be developed. Herein, we report mol. structures, dynamic behaviors, and healability of bis(2,2,6,6-tetramethylpiperidin-1-yl)trisulfide (BITEMPS-S3) to compare with its disulfide analog (BITEMPS-S2) exchanged at moderate temperature Unsym. cleavage of trisulfide linkage induced relatively rapid disproportionation to di- and tetrasulfide derivatives In the bulk, poly(hexyl methacrylate) networks partially containing the BITEMPS-S3 moiety as a crosslinking point afforded nearly quant. damage healability only by simple hot pressing at 110°C under mild pressure. A slightly higher healability of BITEMPS-S2 compared to that of BITEMPS-S3 would be due to the differences in the chain-transfer reaction for the trisulfide linkage during free-radical polymerization rather than thermal exchangeability of the BITEMPS-S3 moiety. Therefore, not only BITEMPS-S2 but also BITEMPS-S3 should be regarded as one of DCBs triggered upon exposure to mild external stimuli.
