Lipophilicity estimation of anti-proliferative and anti-inflammatory 6-substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines

The lipophilicity parameters (logP(calcd), R-M0 and logP(TLC)) of 17 new anti-proliferative and anti-inflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines were determined theoretically using computational methods and experimentally by reversed-phase thin-layer chromatography. The experimental parameter R-M0 was determined on the RP-18 silica plates with acetone-aqueous TRIS buffer as mobile phase. The obtained parameter R-M0 was further transformed into parameter logP(TLC) by use of the calibration curve. The theoretical logP(calcd) values differed depending on the substituents and nature of calculating programs. Fluoroquinobenzothiazines turned out to be rather middling or highly lipophilic compounds. The parameter R-M0 and specific hydrophobic surface area b were meaningly intercorrelated showing congeneric two classes of quinobenzothiazines. The calculated logP(calcd) and experimental logP(TLC) values were compared and intercorrelated to show different prediction power of the computational programs. The lipophilicity was correlated with molecular descriptors (molar mass, molar volume, and molar refractivity), biomolecular descriptors (HIA, PB, MDCK, Caco-2, and BBB) and in vitro tested biological activities (tumor necrosis factor alpha inhibition and antiproliferative activity).

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to implement such knowledge in the development of new catalytic chemistries. Read on for other articles about 5460-09-3. SDS of cas: 5460-09-3.

Selective Construction of Diverse Polycyclic Spirooxindoles via a Three-Component Reaction of Cyclic Mercapto-Substituted beta-Enamino Esters, Isatins, and Cyclic 1,3-Diketones

The three-component reaction of alkyl 2-(benzo[b][1,4]thiazin-3-ylidene)acetates, isatins, and 1,3-indanedione (1,3-cyclopentanedione) in ethanol in the presence of acetic acid conveniently afforded spiro[indeno[1,2-b]phenothiazine-6,3′-indolines] or spiro[cyclopenta[b]phenothiazine-4,3′-indolines] in good yields and with high diastereoselectivity. More interestingly, a similar three-component reaction with 4-hydroxychromen-2-one resulted in the unexpected polycyclic spiro[benzo[b]chromeno[3′,4′:5,6]-pyrano[2,3-e][1,4]thiazine-7,3′-indolines] in satisfactory yields.

Azide based routes to tetrazolo and oxadiazolo derivatives of pyrrolobenzodiazepines and pyrrolobenzothiadiazepines

Tetrazolo- and 1,2,4-oxadiazolo-fused derivatives of the antitumour, antibiotic, DNA-interactive pyrrolo [2,1-c][1,4]benzodiazepines and their pyrrolobenzothiadiazepine derivatives have been produced as analogues of a 1,2,3-triazolo-fused pyrrolobenzothiadiazepine, which was shown to be a Glut-1 transporter inhibitor with potential as an antitumour agent. The tetrazolo-fused systems were produced by intramolecular 1,3-dipolar cycloaddition between an azide and a nitrile. The 1,2,4-oxadiazolo systems were produced by nitrile oxide cycloadditions to pyrrolobenzothiadiazepines, which were in turn produced from a 2-(azidobenzenesulfonyl)-1,2-thiazine 1-oxide. The latter species underwent a phosphite-mediated one-pot sulfur-extrusion, ring-contraction and azide to amine conversion to form 1-(amino-benzenesulfonyl)pyrroles. Bischler-Napieralski ring closure gave the pyrrolobenzothiadiazepines. (C) 2014 Elsevier Ltd. All rights reserved.

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.

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.

Targeting SARS-CoV-2: Novel Source of Antiviral Compound(s) against COVID-19?

SARS-CoV-2 remains a significant burden on human health. Several lines of evidence suggest that surveillance of sewage and waste can provide an early warning sign for COVID-19 recurrence in a community. In support, SARS-CoV-2 traces were found in sewage in several countries. With this in mind, it is notable that pests, such as cockroaches, are exposed to pathogenic microbes routinely, yet thrive in polluted environments. Such species have likely developed mechanisms to protect themselves against pathogens. In support, recent studies showed that cockroaches possess potent antibacterial molecules to shield themselves from pathogenic bacteria. Among hundreds of molecules, some contained thiazine groups, imidazoles, chromene derivatives, isoquinoline group, sulfonamides, pyrrole-containing analogs, flavanones, and furanones. Here, we propose that cockroaches are a potential source of antiviral molecules to thwart infections. Because this is an unexploited resource for potential antivirals, we believe that cockroaches offer a unique source for novel bioactive molecule(s) to counter COVID-19 with huge clinical impact worldwide.

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.
