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.

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.

Thiazine Red(+) platelet inclusions in Cerebral Blood Vessels are first signs in an Alzheimer’s Disease mouse model

Strong evidence shows an association between cerebral vascular diseases and Alzheimer’s disease (AD). In order to study the interaction of beta-amyloid (A beta) plaques with brain vessels, we crossbred an AD mouse model (overexpressing amyloid precursor protein with the Swedish-Dutch-Iowa mutations, APP_SweDI) with mice expressing green fluorescent protein (GFP) under the flt-1/VEGFR1 promoter in vessels (GFP_FLT1). Our data show, that only very few A beta plaques were seen in 4-months old mice, focused in the mammillary body and in the lateral septal nucleus. The number of plaques markedly increased with age being most prominent in 12-months old mice. Thiazine Red was used to verify the plaques. Several Thiazine Red(+) inclusions were found in GFP(+) vessels, but only in non-perfused 4-months old mice. These inclusions were verified by Resorufin stainings possibly representing cerebral amyloid angiopathy. The inclusions were also seen in non-crossbred APP_SweDI but not in wildtype and GFP_FLT1 mice. In order to characterize these inclusions Flow Cytometry (FACS) analysis demonstrated that platelets were specifically stained by Thiazine Red(+), more pronounced when aggregated. In conclusion, our data show that Thiazine Red(+) inclusions representing aggregated platelets are a first pathological sign in AD before plaque development and may become important therapeutic targets in early AD.

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. A plausible reaction mechanism was rationally proposed for formation of different kinds of the spiro compounds, and the stereochemistries of the various spiro compounds were clearly elucidated.

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.

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.

Laccase mediator system obtained from a marine spore exhibits decolorization potential in harsh environmental conditions

Laccases play a significant role in remedying dye pollutants. Most of these enzymes are originated from terrestrial fungi and bacteria, thus they are not proper to be used in the environments with neutral/alkaline pH, or they may require laborious extraction/purification steps. These limitations can be solved using marine spore laccases through high stability and easy to use application. In the current study, laccase activity of the marine spore-forming Bacillus sp. KC2 was measured according to the guaiacol and syringaldazine oxidation. Abiotic stresses like pH of 6, temperature of 37 degrees C and 0.3 mM CuSO4 (in comparison with optimal sporulation conditions: pH of 8, temperature of 20 degrees C and 0.0 mM CuSO4) enhanced laccase formation in sporal coat. Maximum activity of enzyme was observed at 50 degrees C and pH 7, which did not change in the alkaline pH and temperature range of 20-70 degrees C. Results indicated ions, inhibitors and solvent stability of the enzyme and its activity were stimulated by Co2+, Mn2+, PMSF, acetone, acetonitrile, ethanol, and methanol. The spore laccase could decolorize synthetic dyes from various chemical groups including azo (acid orange, amaranth, trypan blue, congo red, and amido black), indigo (indigo carmine), thiazine (methylene blue, and toluidine blue), and triarylmethane (malachite green) with ABTS/syringaldazine mediators after 5 h. Degradation products were not toxic against Sorghum vulgare and Artemia sauna model organisms. The enzyme mediator system showed high potentials for dye bioremediation over a wide range of harsh conditions.

One-pot cis-selective route to sugar-fused thiazines via a masking-unmasking strategy in basic ionic liquid

A novel sequential Knoevenagel condensation, thia-Michael, and amino/mercaptoacetylative ring transformation reaction cascade for cis-selective synthesis of sugar-fused 1,3-thiazine is reported. The expeditious one-pot multicomponent annulation was performed using masked amino acid viz. 2-phenyl-1,3-oxazol-5-one or masked mercaptoacid viz. 2-methyl-2-phenyl-1,3-oxathiolan-5-one, D-xylose/D-glucose, and N-aryldithiocarbamic acid in ionic liquid [bmim] OH. The acetophenone obtained as a by-product and [bmim] OH itself could be easily recycled for further use without loss of efficiency. The envisaged method is operationally simple, high yielding, and excellent diastereoselective in favor of the cis-isomer of fused thiazines.

Phenyliodine(III) Diacetate/I-2-Mediated Domino Approach for Pyrrolo[1,4]Thiazines and 1,4-Thiazines by a One-Pot Morin Rearrangement of N,S-Acetals

An efficient domino transformation using a phenyliodine(III) diacetate (PIDA)/I-2 combination towards Morin 1,4-thiazine compounds has been developed starting from N,S-acetals. The latter leads to one-step regioselective methylene insertion without the need for traditional sulfoxide intermediates in good yields. The reaction involves easily accessible N,S-acetals obtained from cost-effective basic ketones and cysteamine as starting materials. This process ultimately leads to 1,4-thiazines related to natural product and fused derivatives necessary for further QSAR study.
