1,3-Thiazine, 1,2,3,4-Dithiadiazole, and Thiohydrazide Derivatives Affect Lipid Bilayer Properties and Ion-Permeable Pores Induced by Antifungals

Over the past decade, thiazines, thiadiazoles, and thiohydrazides have attracted increasing attention due to their sedative, antimicrobial, antiviral, antifungal, and antitumor activities. The clinical efficacy of such drugs, as well as the possibility of developing resistance to antimicrobials, will depend on addressing a number of fundamental problems, including the role of membrane lipids during their interaction with plasma membranes. The effects of the eight 1,3- thiazine-, 1,2,3,4- dithiadiazole-, and thiohydrazide-related compounds on the physical properties of model lipid membranes and the effects on reconstituted ion channels induced by the polyene macrolide antimycotic nystatin and antifungal cyclic lipopeptides syringomycin E and fengycin were observed. We found that among the tested agents, the fluorine-containing compoundN ‘-(3,5-difluorophenyl)-benzenecarbothiohydrazide (C6) was the most effective at increasing the electric barrier for anion permeation into the hydrophobic region of the membrane and reducing the conductance of anion-permeable syringomycin pores. A decrease in the membrane boundary potential with C6 adsorption also facilitated the immersion of positively charged syringomycin molecules into the lipid bilayer and increases the pore-forming ability of the lipopeptide. Using differential scanning microcalorimetry, we showed that C6 led to disordering of membrane lipids, possibly by potentiating positive curvature stress. Therefore, we used C6 as an agonist of antifungals forming the pores that are sensitive to membrane curvature stress and lipid packing, i.e., nystatin and fengycin. The dramatic increase in transmembrane current induced by syringomycin E, nystatin, and fengycin upon C6 treatment suggests its potential in combination therapy for treating invasive fungal infections.

SERS Spectroscopy and DFT Studies of Thionine and its Derivatives Adsorbed on Silver Colloids: Which N Atom is Used for Coordination of a Phenothiazine-Based Natural Dye to Electron-Deficient Metal Surface?

A Surface-enhanced Raman scattering (SERS) investigation has been carried out for thionine and its derivatives, well known blue-based dyes sharing the phenothiazine core. The thionine SERS spectrum is similar to its Raman spectrum. This suggests that the strong Raman bands mostly arising from in-plane ring modes are also enhanced on metal surface. Several originally weak Raman bands arising from the CNC moiety or H atoms on the thiazine N side also largely strengthen in the SERS spectrum. Density functional theory results for the plausible coordinated structures of thionine and the silver adatom reveal that coordination via the thiazine N atom to Ag+ leads to the most stable structure, and its calculated spectrum also best reproduces the SERS spectrum. The thionine derivatives show surprisingly analogous spectra, reflecting that the derivatives coordinate in a similar fashion to the metal surface. The high preference of the thiazine N atom for coordination is traced to the positive charge on the S atom.

HYDROXYAPATITE AND PORPHYRIN-FULLERENE NANOPARTICLES FOR DIAGNOSTIC AND THERAPEUTIC DELIVERY OF PARAMAGNETIC IONS AND RADIONUCLIDES

Nanoparticles for drug delivery are the subject of extensive research. Importantly, they can transform in size during synthesis or actual use, thereby changing their cytotoxic properties. The aim of the present work was to study the tendency of [Zn-67] porphyrin-fullerene nanoparticles (BFNP) to aggregate over time and to compare the properties of hydroxyapatite (HAP) nanoparticles obtained through 3 different techniques. We found that aggregation of BFNP nanoparticles does not affect their function but attenuates their cytotoxicity against leukemia cells. We were also able to obtain HAP nanoparticles with programmable properties (such as size, shape or the capacity to adsorb metal ions, ligands and chemical complexes) through enzymatic synthesis by varying its conditions. The synthesized HAP nanoparticles contain short-lived isotopes of zinc and copper (in the form of ions and complexes with pyrimidine or thiazine derivatives). These tumoricidal components (a radionuclide and a ligand or a complex) determine the diagnostic and therapeutic potential of the obtained radiopharmaceutical agents.

Synthesis and Antimicrobial Evaluation of some Functionalized Heterocycles Derived from Novel Quinolinyl Chalcone

The reaction of 3-acetyl-4-hydroxyl-1-methylquinolin-2(1H)-one (1) with 10-oxo-4,6,7,8,9,10-hexahydropyrazolo[1,5-a][1]benzothieno[2,3-d]pyrimidine-3-carbaldehyde (2) afforded the novel enone system 3. The latter compound was reacted with some 1,2-binucleophilic reagents to give pyrazoline derivative 4 and isoxazoline derivative 5. Treatment of chalcone 3 with 1,3-binucleophilic reagents afforded pyrimidine and thiazine derivatives 6-8. Moreover, reaction of compound 3 with active methylene reagents furnished pyridine, pyran, and cyclohexanone derivatives 9-12. Cyclization of compound 12 by using hydrazine hydrate yielded indazol-3-one derivative 13. On the other hand, the cyclocondensation of the enone 3 with 1,4-dinucleophilic reagents yielded diazepine derivative 14 and triazolothiadiazepine derivative 15. The characterization of the newly synthesized heterocyles were confirmed on the basis of their elemental analysis and spectral data (IR, NMR, and MS). These compounds were also screened for their antibacterial activities.

Synthesis of Benzo[1,4]thiazines via Ring Expansion of 2-Aminobenzothiazoles with Terminal Alkynes Under Metal-Organic Framework Catalysis

Copper-organic framework Cu-MOF-74 was synthesized, and consequently utilized as a heterogeneous catalyst for the synthesis of benzo[1,4]thiazines via ring expansion of 2-aminobenzothiazoles with terminal alkynes. Different from previous works, the reaction proceeded readily in the presence of lower catalyst concentration, at lower temperature, and under ligand-free conditions. The combination of 5 mol% framework catalyst, 20 mol% Cs2CO3, and 3 equivalents of di-tert-butyl peroxide led to high yields of benzo[1,4]thiazines. This copper-based framework demonstrated higher catalytic efficiency than a series of MOF-based heterogeneous catalysts and traditional homogeneous catalysts. In this system, the donation of soluble active copper species to the formation of benzo[1,4]thiazines was trivial. The copper-organic framework was reutilized without a remarkable decline in catalytic efficiency. To our best knowledge, this ring expansion reaction was not previously performed with a recyclable catalyst. [GRAPHICS] .

Identification and characterization of antibacterial compound(s) of cockroaches (Periplaneta americana)

Infectious diseases remain a significant threat to human health, contributing to more than 17 million deaths, annually. With the worsening trends of drug resistance, there is a need for newer and more powerful antimicrobial agents. We hypothesized that animals living in polluted environments are potential sources of antimicrobials. Under polluted milieus, organisms such as cockroaches encounter different types of microbes, including superbugs. Such creatures survive the onslaught of superbugs and are able to ward off disease by producing antimicrobial substances. Here, we characterized antibacterial properties in extracts of various body organs of cockroaches (Periplaneta americana) and showed potent antibacterial activity in crude brain extract against methicillin-resistant Staphylococcus aureus and neuropathogenic Escherichia coli K1. The size-exclusion spin columns revealed that the active compound(s) are less than 10 kDa in molecular mass. Using cytotoxicity assays, it was observed that pre-treatment of bacteria with lysates inhibited bacteria-mediated host cell cytotoxicity. Using spectra obtained with LC-MS on Agilent 1290 infinity liquid chromatograph, coupled with an Agilent 6460 triple quadruple mass spectrometer, tissues lysates were analysed. Among hundreds of compounds, only a few homologous compounds were identified that contained the isoquinoline group, chromene derivatives, thiazine groups, imidazoles, pyrrole-containing analogs, sulfonamides, furanones, and flavanones and known to possess broad-spectrum antimicrobial properties and anti-inflammatory, anti-tumour, and analgesic properties. Further identification, characterization, and functional studies using individual compounds can act as a breakthrough in developing novel therapeutics against various pathogens including superbugs.
