Electrochemical Evaluation and DFT Studies of 2-(4-chlorophenyl)-3-hydroxy-4,6-dioxo-8-phenyl-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile of Carbon Steel Corrosion in Hydrochloric Acid

In present study corrosion inhibition property of 2-(4-chlorophenyl)-3-hydroxy-4,6-dioxo-8-phenyl-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile (CHPPC) in 1.0 M HCl was investigated using electrochemical impedance spectroscopy, potentiodynamic polarization and DFT studies. From electrochemical measurements it is observed that inhibition efficiency increases with CHPPC concentration and maximum efficiency (98.9) was obtained at 1.0 mM. The potentiodynamic study reveals that pyrimidothiazine derivative is a mixed type inhibitor with predominant cathodic action. EIS plot indicates that the addition of inhibitor increases the charge-transfer resistance (Rct) and decreases the double-layer capacitance (Cdl) of the corrosion process, these observation reveal that investigated pyrimidothiazine derivative inhibits carbon steel corrosion by adsorption mechanism. Adsorption of pyrimidothiazine derivative on carbon steel surface obeys the Langmuir adsorption isotherm. The effect of temperature on the corrosion rate was investigated and some thermodynamic parameters were also calculated in order to explain the mechanism of adsorption. A theoretical study of the corrosion inhibition efficiency of this pyrimidothiazine derivative, was carried out using density functional theory (DFT) at the B3LYP/6-31G(d) level of theory.

Novel arylazothiazoles and arylazo[1,3,4]thiadiazoles as potential antimicrobial and anticancer agents: synthesis, molecular modeling, and biological screening

In this study, we tested two novel series of 5-arylazo-2-hydrazonothiazoles 6a-g and 2-hydrazono[1,3,4]thiadiazoles 12a-c as antimicrobial and anticancer agents. These series were prepared from the reactions of 2-{1-[4-(2,4-dihydroxyphenylazo)phenyl]ethylidene}thiosemi-carbazide (3) with alpha-keto hydrazonoyl halides and N-aryl arenecarbohydrazonoyl halides. The structures of the newly synthesized compounds were elucidated by infrared, H-1 and C-13 nuclear magnetic resonance, and gas chromatography mass spectrometry spectral data. The antibacterial activity against two types of Gm +ve bacteria and, two types for Gm -ve bacteria, and the antifungal activity against four fungi microorganisms were evaluated by a well diffusion method for the synthesized compounds. Of these novel compounds, thiazole derivatives 6a-g showed mostly promising antibacterial activity against Gm +ve strains and antifungal activity compared to the reference drugs. A successful step was achieved to explain of their mode of action through molecular docking of the most active molecules at a target enzyme, CYP51. Moreover, the antiproliferative activity was tested against three human carcinoma cell lines [human colon carcinoma (HCT-116), human breast adenocarcinoma (MCF-7), and human liver carcinoma (HEPG-2)], showing promising anticancer activities compared to the doxorubicin drug. The data suggest that the arylthiazole scaffold derivatives 6a-g exhibited good antimicrobial and anticancer activities and might be used as leads for further optimization.

The complex of zinc with N-(5,6-dihydro-4H-1,3-thiazine-2-yl)benzamide

A complex of zinc with N-(5,6-dihydro-4H-1,3-thiazin-2-yl)benzamide (L) ligand, LZnCl2, was synthesized for subsequent medical trials. The molar extinction coefficients were determined for LHBr solutions in water and physiological saline, and for LZnCl2 ethanol solution. The ligand stability in various solvents was evaluated and the value of its protonation constant was found for the physiological saline solution, logK = 5.3 +/- 0.2. The impossibility of determination of the complex stability constant by the potentiometric titration method was demonstrated. The complex exhibited an insufficient stability in aqueous and physiological saline solutions, but was stable as the solution in alcohol. There was no sorption observed upon the treatment of ligand with hydroxyapatite nanoparticles, which could be a potential carrier for the therapeutic form of LZnCl2, providing additional degrees of freedom for the interaction of ligand with cell membranes and a prolonged action of zinc ions.

Synthesis of 5,6-dihydro-4H-1,3-thiazine containing peptide mimics from N-(3-hydroxypropyl)thioamides and epimerization studies

The first synthesis of 1,3-thiazine fused peptide mimics is described from N-(3-hydroxypropyl)thioamides under MsCl/NEt3 conditions. The method is amenable to oligopeptidomimics with polar and apolar side chains. Substantial epimerization occurs at chiral C(2) exo methines in non-Pro fused mimics even under neutral conditions. H-1 NMR and crystal structure analyses indicate that the Thi analogues primarily associate with each other through intermolecular hydrogen bonds, involving the nitrogen of 1,3-thiazine and the N-H of the fused residue, which may be the basis for enamination-racemization process in these peptide mimics.

Crystal structures of two 2,3-diary1-2,3-dihydro-4H1,3-benzothiazin-4-ones

The syntheses and crystal structures of 2,3-bis[3-(trifluoromethyl)phenyl]-2,3dihydro-4H-1,3-benzothiazin-4-one (di-m-CF3; C22H13F6NOS) (1) and 2,3-bis(4-methylphenyl)-2,3-dihydro-4H-1,3-benzothiazin-4-one (di-p-CH3; C22H9NOS) (2) are reported. Each structure is racemic: the asymmetric unit of 2 consists of two molecules. In both 1 and 2, the six-membered 1,3-thiazine ring is close to an envelope conformation with the chiral C atom forming the flap. In 1, the 2-aryl group is pseudo-equatorial, while in 2 it is pseudo-axial. In 1, the pendant aryl rings form a V shape with an inter-centroid distance of 3.938 (3) A and an acute dihedral angle of 48.3 (2) between them. Both CF3 groups are disordered over two orientations in 0.687 (19):0.313 (19) and 0.667 (16):0.33 (16) ratios. In each of the independent molecules of 2, the aryl rings are almost orthogonal to each other [dihedral angles = 85.50 (12) and 86.07 (11) I. In both structures, the chiral C atom and the 0 atoms participate in C-H center dot center dot center dot O-type hydrogen bonding between symmetry-related molecules of 1 or the independent enantiomers in 2, forming chains along the c-axis direction in 1 and the b-axis direction in 2. Additionally, in 1, pi-pi contacts of both face-to-face and edge-to-face type, as well as pi-H center dot center dot center dot O and pi-H center dot center dot center dot F interactions are observed. In 2, a racemic mixture of molecules forms layers in the ac plane linked by weak pi-pi and C-H center dot center dot center dot pi interactions.
