A series of Fe/h-BN catalysts promoted with Cu or Mn were prepared for Fischer-Tropsch synthesis (FTS). The physicochemical properties, crystal structures and morphologies of the catalysts were characterized by N-2 physisorption, FT-IR, TPR, XPS, XRD, MES and TEM. It is found that iron oxide nanoparticles are highly dispersed on h-BN matrix due to the anchoring effect of surface defects and the accommodation of porous structures of h-BN. The characterization results indicate that strong interaction between iron oxide and h-BN is present on un-promoted catalyst, which endows the h-BN supported iron catalyst with stable properties under FTS conditions but severely retards reduction of the catalyst. The addition of Cu to Fe/h-BN can to some extent overcome the strong interaction by introducing more sites for dissociating H-2. It is observed that Cu promoter can increase the reduction or carburization degree and thus enhance the FTS activity. The addition of Mn to Fe/h-BN can weaken the strong interaction by altering the electron structure of iron species. And the electron-rich Fe species are responsible for easy reduction and the enhanced FTS performance. Besides, a higher activity can be realized by co-adding Cu and Mn to the Fe/h-BN catalyst. These results suggest that the synergistic effect of Mn and Cu can largely improve the performance of Fe/h-BN catalyst without impairing the stability of the catalyst. The present study paves a way to tailor the performances of FTS catalysts with h-BN as support.

The Pomeranz-Fritsch reaction and its Schlittler-Muller modification were successfully applied in the Ugi postcyclization strategy by using orthogonally protected aminoacetaldehyde diethyl acetal and complementary electron rich building blocks. Several scaffolds, including isoquinolines, carboline, alkaloid-like tetrazole-fused tetracyclic compounds, and benzo[d]azepinone scaffolds, were synthesized in generally moderate to good yield. All our syntheses provide a short MCR-based sequence to novel or otherwise difficult to access scaffolds. Hence, we foresee multiple applications of these synthesis technologies.

The chlorination of a bioactive compound can change its physiological properties and improve its pharmacokinetic and pharmacological profiles. It therefore has been an important strategy for drug discovery and development. However, the direct aromatic chlorination of complex bioactive molecules is too difficult to be practical. In fact, many functional groups such as hydroxyls, amines, amides or carboxylic acids may strongly restrain the reactivity of Cl+ by forming a halogen bond. Here we report a highly efficient aromatic chlorination of arenes that is catalysed by dimethyl sulfoxide with N-chlorosuccinimide as the chloro source. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, drugs and peptides. The multi-gram experiment and low-cost of N-chlorosuccinimide and dimethyl sulfoxide shows great potential for drug discovery and development in industrial applications. Late-stage aromatic chlorination of active pharmaceutical ingredients has enormous potential in drug discovery yet still features limited applicability due to issues of functional-group tolerance. Now, dimethyl sulfoxide is reported as catalyst for the chlorination of a diverse family of bioactive molecules in combination with N-chlorosuccinimide.

To develop antitumor drugs capable of targeting energy metabolism in the tumor microenvironment, we produced a series of potent new biguanide derivatives via structural modification of the arylbiguanide scaffold. We then conducted biological screening using hypoxia inducible factor (HIF)-1- and unfolded protein response (UPR)-dependent reporter assays and selective cytotoxicity assay under low glucose conditions. Homologation studies of aryl-(CH2)(n)-biguanides (n=0-6) yielded highly potent derivatives with an appropriate alkylene linker length (n=5, 6). The o-chlorophenyl derivative 7l (n=5) indicated the most potent inhibitory effects on HIF-1- and UPR-mediated transcriptional activation (IC50; 1.0 +/- 0.1 mu M, 7.5 +/- 0.1 mu M, respectively) and exhibited selective cytotoxicity toward HT29 cells under low glucose condition (IC50; 1.9 +/- 0.1 mu M). Additionally, the protein expression of HIF-1 alpha induced by hypoxia and of GRP78 and GRP94 induced by glucose starvation was markedly suppressed by the biguanides, thereby inhibiting angiogenesis. Metabolic flux and fluorescence-activated cell sorting analyses of tumor cells revealed that the biguanides strongly inhibited oxidative phosphorylation and activated compensative glycolysis in the presence of glucose, whereas both were strongly suppressed in the absence of glucose, resulting in cellular energy depletion and apoptosis. These findings suggest that the pleiotropic effects of these biguanides may contribute to more selective and effective killing of cancer cells due to the suppression of various stress adaptation systems in the tumor microenvironment.

Because of their stable orientations and their minimal interference with native DNA interactions and folding, emissive isomorphic nucleoside analogues are versatile tools for the accurate analysis of DNA structural heterogeneity. Here, we report on a bifunctional trifluoromethylphenylpyrrolocytidine derivative ((FP)dC) that displays an unprecedented quantum yield and highly sensitive F-19 NMR signal. This is the first report of a cytosine-based dual-purpose probe for both fluorescence and F-19 NMR spectroscopic DNA analysis. (FP)dC and (FP)dC-containing DNA were synthesized and characterized; our robust dual probe was successfully used to investigate the noncanonical DNA structure, i-motifs, through changes in fluorescence intensity and F-19 chemical shift in response to i-motif formation. The utility of (FP)dC was exemplified through reversible fluorescence switching of an (FP)dC-containing i-motif oligonucleotide in the presence of Ag(i) and cysteine.

The use of gaseous allene as an ally! pronu-cleophile in enantioselective aldehyde reductive coupling is described. Notably, using the same antipode of chiral ligand, (S)-tol-BINAP, an inversion of enantioselectivity is observed for allene versus allyl acetate pronucleophiles. Experimental and computational studies corroborate intervention of diastereo-meric pi-allyliridium-C,O-benzoate complexes, which arise via allene hydrometalation (from a pentacoordinate iridium hydride) versus ally! acetate ionization (from a square planar iridium species).

Redox modulators have been developed as an attractive approach to treat cancer. Herein, we report the synthesis, identification, and biological evaluation of a quinazolinedione reactive oxygen species (ROS) inducer, QD394, with significant cytotoxicity in pancreatic cancer cells. QD394 shows a transcriptomic profile remarkably similar to napabucasin, a cancer stemness inhibitor. Both small molecules inhibit STAT3 phosphorylation, increase cellular ROS, and decrease the GSH/GSSG ratio. Moreover, QD394 causes an iron- and ROS-dependent, GPX4 mediated cell death, suggesting ferroptosis as a major mechanism. Importantly, QD394 decreases the expression of LRPPRC and PNPT1, two proteins involved in mitochondrial RNA catabolic processes and both negatively correlated with the overall survival of pancreatic cancer patients. Pharmacokinetics-guided lead optimization resulted in the derivative QD394-Me, which showed improved plasma stability and reduced toxicity in mice compared to QD394. Overall, QD394 and QD394-Me represent novel ROS-inducing drug-like compounds warranting further development for the treatment of pancreatic cancer.

A mild one-pot protocol for the synthesis of symmetrical biaryls by sequential Ir-catalyzed C-H borylation and Cu-catalyzed homocoupling of arenes is described. The regiochemistry of the biaryl formed is sterically controlled as dictated by the C-H borylation step. The methodology is also successfully extended to heteroarenes. Some of the products obtained by this approach are impossible to obtain via the Ullmann or the Suzuki coupling protocols. Finally, we have shown a one-pot sequence describing C-H borylation/Cu-catalyzed homocoupling/Pd-catalyzed Suzuki coupling to obtain pi-extended arene frameworks.

Endeavor to discover biorational natural products-based insecticides, two series (27) of novel 9R/S-acyloxy derivatives of cinchonidine and cinchonine were prepared and assessed for their insecticidal activity against Mythimna separata in vivo by the leaf-dipping method at 1 mg/mL. Among all the compounds, especially derivatives 6l and 6o exhibited the best insecticidal activity with final mortality rates of 75.0% and 71.4%, respectively. Overall, a free 9-hydroxyl group is not a prerequisite for insecticidal activity and C9-substitution is well tolerated; the configuration of C8/9 position is important for insecticidal activity, and 9S-configuration is optimal; 6′-OCH3 moiety is not necessary, removal of it is also acceptable.
