Stereoselective Synthesis and Antiproliferative Activity of Monoterpene-Fused 2-Imino-1,3-oxazines

Background: In the recent years the 2-imino-1,3-thiazine and 2-iminothiazolidine ring systems can be found as moieties in biologically relevant compounds, including BACE1 inhibitors, or cannabinoid receptor agonists, while monoterpene-based 2-imino-1,3-thiazines, prepared from chiral 1,3-amino alcohols exhibiting pronounced antiproliferative activity. Methods: The antiproliferative activities of the prepared compounds were determined in vitro against a panel of human adherent cancer cell lines including HeLa, MCF7 and A431 by MTT assay. Results: Starting from pinane-, apopinane-and carane-based beta-amino acid derivatives, 1,3-amino alcohols were prepared via two-step syntheses. The reactions of the product 1,3-amino alcohols and aryl isothiocyanates yielded gamma-hydroxythioureas, which were transformed to monoterpene-fused 2-imino-1,3-oxazines via base-catalysed ring closure. The antiproliferative activities of these 2-imino-1,3-oxazines were examined and the structure-activity relationships were studied from the aspects of the type and stereochemistry of the monoterpene ring and the substituent effects on the 1,3-oxazine ring system. The N-unsubstituted monoterpene-based derivatives exhibited considerable antiproliferative activity against a panel of human adherent cancer cell lines (HeLa, MCF7 and A431). Conclusions: A mild and efficient method has been developed for the synthesis of 2-imino-1,3-oxazines by the ring closure of thiourea adducts of 1,3-amino alcohols. The resulting 1,3-oxazines exert marked antiproliferative action on a panel of human cancer cell lines.

The role of S-bond in tenoxicam keto-enolic tautomerization

A non-steroidal anti-inflammatory drug, 4-hydroxy-2-methyl-N-2-pyridyl-2H-thieno.2,3-e)-1,2-thiazine-3-carboxamide 1,1-dioxide, called tenoxicam (TXM), with important implications in cancer treatment, has a peculiarity with respect to other molecules from the oxicam family. TXM is predominantly found in the zwitterionic form (ZWC) within the crystal structures of pure compounds and their solvates; however, it can be present in the beta-keto-enolic form (BKE) or beta-diketone (BDK) form. To understand this phenomenon, the combined effects of environment (solvent) and intra-molecular non-covalent interactions on the TXM keto-enol tautomerization were investigated through a combined experimental and computational study. We found that the polarity of a solvent had a minor influence on the crystallization process; this allowed to us synthesize and solve six new solvates with TXM in the ZWC form. Careful investigation of the non-covalent interactions between the sulphur atom of thiophenyl moiety and oxygen of the carbonyl group (S-bond) through a computational approach with the natural bond orbital (NBO) theory has shown that TXM crystallization is modulated by the S-bond. This study further confirms the importance of the S-bond in the drug design; however, nowadays, it is still underestimated.

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.

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.

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.

Experimental and Theoretical Studies of the Corrosion Inhibition of 4-amino-2-(4-chlorophenyl)-8-(2, 3-dimethoxyphenyl)-6-oxo-2, 6-dihydropyrimido [2, 1-b][1, 3] thiazine-3,7-dicarbonitrile on Carbon Steel in a 1.0 M HCl Solution

The corrosion inhibition of carbon steel in a 1.0 M HCl solution, using 4-amino-2-(4-chlorophenyl)-8-(2,3-dimethoxyphenyl)-6-oxo-2,6-dihydropyrimido[2, 1b][1,3] thiazine-3,7-dicarbonitrile (ACMPT) was investigated by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and quantum chemical calculations. Polarization curves indicate that the studied compound was acting as a mixed inhibitor with predominant cathodic effectiveness. The inhibition efficiency decreased with an increased temperature, and the thermodynamic and activation parameters obtained from this study were discussed. The adsorption behavior of ACMT follows Langmuir’s isotherm. In addition, Density Function Theory (DFT) calculations were performed on the studied molecule. The theoretical parameters obtained from this method are in good agreement with the experimental results.

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).
