A new carbon-nitrogen organic semiconductor has been synthesized by pyrolysis of uric acid. This layered carbon-nitrogen material contains imidazole-, pyridine (naphthyridine)- and graphitic-like nitrogen, as evinced by infrared and X-ray photoelectron spectroscopies. Quantum chemistry calculations support that it would consist of a 2D polymeric material held together by hydrogen bonds. Layers are stacked with an interplanar distance between 3.30 and 3.36 A, as in graphite and coke. Terahertz spectroscopy shows a behavior similar to that of amorphous carbons, such as coke, with non-interacting layers. This material features substantial differences from polymeric carbon nitride, with some characteristics closer to those of nitrogen-doped graphene, in spite of its higher nitrogen content. The direct optical band gap, dependent on the polycondensation temperature, ranges from 2.10 to 2.32 eV. Although in general the degree of crystallinity is low, in the material synthesized at 600 C some spots with a certain degree of crystallinity can be found.

Different studies about the anticancer potential of several medically used antibacterial fluoroquinolones have been established. Fluoroquinolone derivatives, like some anti-cancer drugs, such as doxorubicin, can achieve antitumor activity via poisoning of type II human DNA topoisomerases. Interestingly, structural features required for the anticancer activity of quinolones have been determined. Most of the chemical modifications required to convert antibacterially acting fluoroquinolones into their anticancer analogs were at position 7 and the carboxylic group at position 3. This review highlights the antitumor potential of fluoroquinolones in general and summarizes the chemical modifications carried out on fluoroquinolones to become anticancer agents. Moreover, the review gives a quick recap on metal ion chelates with fluoroquinolones and their substantial role in topoisomerase poisoning and antitumor potential improvement. Hence, it should be highly interesting for researchers attempting to design and synthesize novel anticancer fluoroquinolone candidates.

A series of novel gemifloxacin (GMFX) derivatives containing a substituted benzyloxime moiety with remarkable improvement in lipophilicity were synthesized. The target compounds evaluated for their in vitro antibacterial activity against representative strains. Our results reveal that most of the target compounds have considerable potency against all of the tested Gram-positive strains including MRSA and MRSE (MIC: <0.008-8 mug/mL), although they are generally less active than the references against the Gram-negative strains. In particular, compound 11l (MIC: <0.008-4 mug/mL) was found to be 8-2048 and 2-128 times more potent than levofloxacin (LVFX) and GMFX against the Gram-positive strains, respectively. Moreover, against MRSA clinical isolates, 11l (MIC90: 1 mug/mL) is 8-fold more active than GMFX, and 2-fold more active than GMFX and moxifloxacin against MRSE clinical isolates (MIC90: 4 mug/mL).

As circulating monocytes enter the site of disease, the local microenvironment instructs their differentiation into tissue macrophages (MPhi). To identify mechanisms that regulate MPhi differentiation, we studied human leprosy as a model, since M1-type antimicrobial MPhi predominate in lesions in the self-limited form, whereas M2-type phagocytic MPhi are characteristic of the lesions in the progressive form. Using a heterotypic co-culture model, we found that unstimulated endothelial cells (EC) trigger monocytes to become M2 MPhi. However, biochemical screens identified that IFN-gamma and two families of small molecules activated EC to induce monocytes to differentiate into M1 MPhi. The gene expression profiles induced in these activated EC, when overlapped with the transcriptomes of human leprosy lesions, identified Jagged1 (JAG1) as a potential regulator of MPhi differentiation. JAG1 protein was preferentially expressed in the lesions from the self-limited form of leprosy, and localized to the vascular endothelium. The ability of activated EC to induce M1 MPhi was JAG1-dependent and the addition of JAG1 to quiescent EC facilitated monocyte differentiation into M1 MPhi with antimicrobial activity against M. leprae. Our findings indicate a potential role for the IFN-gamma-JAG1 axis in instructing MPhi differentiation as part of the host defense response at the site of disease in human leprosy.

Despite significant advances in the catalytic direct arylation of heteroarenes, the application of this reaction to pyridines has been met with limited success. An oxidative nucleophilic arylation strategy has been developed to overcome this problem. Pyridine, pyrazine, quinolone, and related electron-deficient N-heteroarenes can be arylated at the most electrophilic site using the developed nickel-catalyzed reaction. This protocol serves as a complementary method to catalytic direct arylation reactions.
