The worldwide use of the broad-spectrum antimicrobial trimethoprim (TMP) has induced the rise of TMP-resistant microorganisms. In addition to resistance-causing mutations of the microbial chromosomal dihydrofolate reductase (Dfr), the evolutionarily and structurally unrelated type II Dfrs (DfrBs) have been identified in TMP-resistant microorganisms. DfrBs are intrinsically TMP-resistant and allow bacterial proliferation when the microbial chromosomal Dfr is TMP-inhibited, making these enzymes important targets for inhibitor development. Furthermore, DfrBs occur in multiresistance plasmids, potentially accelerating their dissemination. We previously reported symmetrical bisbenzimidazoles that are the first selective inhibitors of the only well-characterized DfrB, DfrB1. Here, their diversification provides a new series of inhibitors (K-i = 1.7-12.0 mu M). Our results reveal two prominent features: terminal carboxylates and inhibitor length allow the establishment of essential interactions with DfrB1. Two crystal structures demonstrate the simultaneous binding of two inhibitor molecules in the symmetrical active site. Observations of those dimeric inhibitors inspired the design of monomeric analogues, binding in a single copy yet offering similar inhibition potency (K-i = 1.1 and 7.4 mu M). Inhibition of a second member of the DfrB family, DfrB4, suggests the generality of these inhibitors. These results provide key insights into inhibition of the highly TMP-resistant DfrBs, opening avenues to downstream development of antibiotics for combatting this emergent source of resistance.

Selective reduction of esters to alcohols was accomplished through Mn(I)-mediated hydrosilylation reaction. The manganese tricarbonyl complex [Mn(bis-NHC)(CO)(3)Br] resulted an active pre-catalyst for the reduction of a variety of esters using phenylsilane and the cheap and readily available polymethylhydrosiloxane. Anin situexamination of the catalytic reaction using(55)Mn NMR spectroscopy allowed us to detect the formation of Mn(I) intermediate active species.

A highly efficient bifunctional catalyst of an s-triazine-based carbon-nitride-supported cobalt oxide is developed for the aerobic oxidation-Knoevenagel condensation tandem reaction of benzyl alcohol and malononitrile, whereby 96.4% benzyl alcohol conversion with nearly 100% selectivity towards benzylmalononitrile can be obtained in 6 h at 80 degrees C. The excellent catalytic performance derives from the high basicity of carbon nitride and strong redox ability of Co species induced by carbon nitride. The catalyst is also quite stable and can be reused without any regeneration treatment, whose product yield is only an 11.5% reduction after four runs.

Two series of novel morpholinopyrimidine derivatives were synthesized and screened for their in-vitro cytotoxic activity against 60 tumor cell line by the National Cancer Institute, USA. The in-vitro cytotoxic IC50 values for the most active compounds 6e, 6g, and 6l against the most sensitive cell line leukemia SR were estimated (IC50 = 0.76, 13.59, and 4.37 uM, respectively). To investigate their PI3K enzyme inhibition activity, the assay was done on Class IA (alpha, beta, & delta) isoforms. The IC50 values were very promising: compound [6e = 11.73 (alpha), 6.09 (beta), 11.18 (delta)], compound [6g = 8.43 (alpha), 15.84 (beta), 30.62 (delta)], and compound [6l = 13.98 (alpha), 7.22 (beta), 10.94 (delta)], compared to the reference compound LY294002 = 6.28 (alpha), 4.51 (beta), 4.60 (delta) uM, respectively. Moreover, cell cycle analysis and annexin V-FITC staining were done on Leukemia SR, there was arrest at G2/M phase and apoptosis was induced. Finally, docking study was performed to analyze the interactive mode of these derivatives in PI3K alpha ATP-binding site. These outcomes proved that compounds 6e, 6g, and 6l are potential leads for further optimization as antileukemic agents.

Phenols from various man-made activities pose threats to public health and aquatic ecosystems. A number of technologies (e.g., adsorption, oxidation, and biological methods) have been proposed and tested to remove phenolic compounds from different sources. Among these technologies, oxidation process is considered one of the most efficient tools for abating phenolic compounds because of low cost, easy scalability, and ecofriendly production. In this work, we aim to synthesize and characterize potential catalysts (Co(II) and Cu(II) phthalocyanines 6 and 7) for phenolic compounds oxidation. Different parameters influenced the oxidation process were determined and phenolic compounds oxidize to the less harmful products with high conversion and yield in the presence of Co(II) and Cu(II) phthalocyanine catalysts.

Nanostructured and reusable 3d-metal catalysts that operate with high activity and selectivity in important chemical reactions are highly desirable. Here, a cobalt catalyst was developed for the synthesis of primary amines via reductive amination employing hydrogen as the reducing agent and easy-to-handle ammonia, dissolved in water, as the nitrogen source. The catalyst operates under very mild conditions (1.5 mol% catalyst loading, 50 degrees C and 10 bar H-2 pressure) and outperforms commercially available noble metal catalysts (Pd, Pt, Ru, Rh, Ir). A broad scope and a very good functional group tolerance were observed. The key for the high activity seemed to be the used support: an N-doped amorphous carbon material with small and turbostratically disordered graphitic domains, which is microporous with a bimodal size distribution and with basic NH functionalities in the pores.

The enhancement of reactivity inside supramolecular coordination cages has many analogies to the mode of action of enzymes, and continues to inspire the design of new catalysts for a range of reactions. However, despite being a near-ubiquitous class of reactions in organic chemistry, enhancement of the reduction of carbonyls to their corresponding alcohols remains very much underexplored in supramolecular coordination cages. Herein, we show that encapsulation of small aromatic aldehydes inside a supramolecular coordination cage allows the reduction of these aldehydes with the mild reducing agent sodium cyanoborohydride to proceed with high selectivity (ketones and esters are not reduced) and in good yields. In the absence of the cage, low pH conditions are essential for any appreciable conversion of the aldehydes to the alcohols. In contrast, the specific microenvironment inside the cage allows this reaction to proceed in bulk solution that is pH-neutral, or even basic. We propose that the cage acts to stabilise the protonated oxocarbenium ion reaction intermediates (enhancing aldehyde reactivity) whilst simultaneously favouring the encapsulation and reduction of smaller aldehydes (which fit more easily inside the cage). Such dual action (enhancement of reactivity and size-selectivity) is reminiscent of the mode of operation of natural enzymes and highlights the tremendous promise of cage architectures as selective catalysts.

A series of novel pteridinone derivatives possessing a hydrazone moiety were designed, synthesized and evaluated for their biological activity. Most of the synthesized compounds demonstrated moderate to excellent activity against A549, HCT116 and PC-3 cancer cell lines. In particular, compound L-19 exhibited the most potent antiproliferative effects on three cell lines with IC50 values of 3.23 mu M, 4.36 mu M and 8.20 mu M, respectively. In kinase assays, the compound L-19 also showed potent inhibition activity toward PLK1 with % inhibition values of 75.1. Further mechanism studies revealed that compound L-19 significantly inhibited proliferation of HCT-116 cell lines, induced a great decrease in mitochondrial membrane potential resulting in apoptosis of cancer cells, inhibited the migration of tumor cells, and arrested G1 phase of HCT116 cells.
