Synthesis, biological activity, distribution and membrane permeability of novel spiro-thiazines as potent neuroprotectors

New spiro-derivatives of 1,3-thiazine-potential neuroprotectors have been synthesized. It has been determined that the obtained compounds are biologically active and capable of blocking the glutamate-induced calcium ion uptake into synaptosomes of rat brain cortex. The inhibitory activity of the test substances was shown to depend on the chemical nature and structure of the substituents bound with an exocyclic nitrogen atom. Non-polar alkyl and polar radicals with halogen, oxygen and nitrogen atoms were used as substituents. It is typical of the active spiro-thiazines to have alkyl substituents in ortho-and para-position of the benzene ring. Among the investigated spiro-thiazines it is the derivatives with ethyl- and isopropyl-groups in the aril part of the molecules that are the lead-compounds with a high inhibitory ability. We measured the distribution coefficients of the substances in octanol/buffer and hexane/buffer systems and made conclusions about the ability of the investigated drug-like compounds to penetrate the biological membranes. By using the parabolic model we derived a quadratic equation that allowed us to evaluate quantitatively the inhibitory activity of spiro-thiazines with hydrophobic substituents based on lipophilicity data. We also studied the permeability through the phospholipidic membrane and introduced a correlation equation describing the dependence of the investigated spiro-thiazines activity on the descriptors characterizing the donor acceptor properties.

Synthesis of Pyrazine-1,3-thiazine Hybrid Analogues as Antiviral Agent Against HIV-1, Influenza A (H1N1), Enterovirus 71 (EV71), and Coxsackievirus B3 (CVB3)

A novel series of pyrazine-1,3-thiazine hybrid conjugates were synthesized in excellent yield. These derivatives were subsequently tested against human immunodeficiency virus (HIV-1); hemagglutinin type 1 and neuraminidase type 1’influenza’ A (H1N1) virus; enterovirus 71 (EV71); and coxsackievirus B3. The effect of these conjugates on the key enzymes responsible for the progression of these viral infections was also illustrated via enzyme-based assay, such as HIV-1 reverse transcriptase (RT) and neuraminidase, where entire tested molecules showed considerable inhibition. Particularly, among the tested derivatives, compound 3k was identified as most promising inhibitor of HIV-1 with 94% of inhibition (IC50 3.26 +/- 0.2 m). Moreover, the compound 3d was found to be the most potent analogue to inhibit the H1N1 virus with IC50 of 5.32 +/- 0.4 m together with inhibition of the neuraminidase enzyme (IC50 11.24 +/- 1.1 m). In regard to inhibitory activity against enterovirus 71 (EV71) and coxsackievirus B3 (CVB3), the tested derivatives showed considerable inhibition of infection. Molecular docking studies were also performed for the most promising inhibitors with their corresponding target protein to exemplify the structural requirement for better inhibitory activity. The results of inhibitory assay showed that designed molecules possess considerable inhibitory activity against the virus tested.

Evaluation of the effect of 2-(2,4-dihydroxyphenyl)-4H-benzofuro[3,2-d][1,3]thiazin-4-one on colon cells and its anticancer potential

In this paper, we present the biological effect of the newly synthesized 2-(2,4-dihydroxyphenyl)-4H-benzofuro[3,2-d][1,3]thiazin-4-one (DPBT) on human colon adenocarcinoma cell lines (HT-29 and LS180). Additionally, DPBT cytotoxicity was examined in human colon epithelial cells (CCD 841 CoTr) and human skin fibroblasts (HSF). The studies revealed a significant decrease in the proliferation of cancer cells after exposure to DPBT at concentrations in the range of 10-100 mu M. Additionally, DPBT was not toxic to normal CCD 841 CoTr and HSF cells at concentrations that induced inhibition of cancer cell proliferation. The nature of the anti-proliferative action of DPBT in the cell cycle progression in colon cancer cells and the expression of proteins involved in this process were examined by flow cytometry and western blotting, respectively. The investigations demonstrated higher sensitivity of LS180 than HT-29 to the DPBT treatment. The anti-proliferative action of DPBT in LS180 was attributed to cell cycle arrest in the G(1) phase via up-regulation of p27(KIP1) and down-regulation of cyclin D1 and CDK4 proteins.

Crystal structure, Hirshfeld surface analysis and interaction energy and DFT studies of (2Z)-4-benzyl-2-(2,4-dichlorobenzylidene)-2H-1,4-benzothiazin-3(4H)-one

The title compound, C22H15Cl2NOS, contains 1,4-benzothiazine and 2,4-dichlorobenzylidene units, where the dihydrothiazine ring adopts a screw-boat conformation. In the crystal, intermolecular C-H-Bnz center dot center dot center dot O)(Thz) (Bnz = benzene and Thz = thiazine) hydrogen bonds form corrugated chains extending along the b-axis direction which are connected into layers parallel to the be plane by intermolecular C-H-Methy center dot center dot center dot S-Thz (Methy = methylene) hydrogen bonds, enclosing R-4(4)(22) ring motifs. Offset pi-stacking interactions between 2,4-dichlorophenyl rings [centroid-centroid = 3.7701 (8) angstrom] and pi-interactions which are associated by C-H-Bnz center dot center dot center dot pi(ring) and C-H-Dehlphy center dot center dot center dot pi(ring) (Dchlphy = 2,4-dichlorophenyl) interactions may be effective in the stabilization of the crystal structure. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (29.1%), H center dot center dot center dot C/C center dot center dot center dot H (27.5%), H center dot center dot center dot Cl/Cl center dot center dot center dot H (20.6%) and O center dot center dot center dot H/H center dot center dot center dot O (7.0%) interactions. Hydrogen-bonding and van der Waals interactions are the dominant interactions in the crystal packing. Computational chemistry indicates that in the crystal, the C-H-Bnz center dot center dot center dot O-Thz and C-H-Methy center dot center dot center dot S-Thz hydrogen-bond energies are 55.0 and 27.1 kJ mol(-1), respectively. Density functional theory (DFT) optimized structures at the B3LYP/6-311G(d,p) level are compared with the experimentally determined molecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

Mass Spectral Profile for Rapid Differentiating Beta-Lactams from Their Ring-Opened Impurities

High performance liquid chromatography tandem mass spectrometry (HPLC MS) has been widely used for beta-lactam antibiotics determination. However, its application to identify impurities of these frequently used drugs is not sufficient at present. In this job, characteristic profiles of the collision induced dissociation (CID) spectra of both beta-lactams and ring-opened beta-lactams were extracted from the MS data of six beta-lactam antibiotics and their forty-five impurities, and were confirmed by the MS data reported in the literature. These characteristics have been successfully applied to rapid differentiation of beta-lactam and ring-opened beta-lactam impurities in cefixime, cefdinir, and cefaclor. However, these characteristic profiles can only be obtained under low activating voltage. They did not display in the high energy activated CID spectra. Diagnostic fragmentations for determining the localization of double bond and substituents on the thiazine ring and the side chain were also observed. In addition, several characteristic fragmentations are hopeful to be used to differentiate the configurations of C-2 on the thiazine ring of ring-opened impurities, which is generally disadvantageous of mass spectrometry. Taken together, forty-five impurities were identified from the capsules of cefixime, cefdinir, and cefaclor.

Organic Synthesis with N-Heterocyclic Carbenes of Indazole: Synthesis of Benzo(thio)imidates, Benzo[d][1,3]thiazines and Quinazoline-4-thiones

The N-heterocyclic carbenes of indazole, generated by deprotonation of indazolium salts, proved to be versatile starting materials for organic synthesis. They undergo ring-opening reactions to generate ketenimines which readily add thiols thus affording what are, to the best of our knowledge, the first examples of 2-anilinobenzothioimidates. Water converts the ring-opened intermediates into functionalized 2-anilinobenzamides which can be thionated with Lawesson’s reagent and subsequently cyclized with formaldehyde and propionaldehyde, respectively, to give benzo[d][1,3]thiazines and quinazoline-4-thiones. The outcome of the cyclization depends upon the thiobenzamide substitution pattern.
