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.

Paper-based diagnostic devices for evaluating the quality of human sperm

Male infertility, which amounts to half of all infertility cases, is a serious problem worldwide. The percentage of fertility-related patients in sub-Saharan African countries is higher than that for the developed countries. In low-resource countries, examination of sperm characteristics for male infertility cannot be undertaken because of poor clinical access. To evaluate male fertility in assisted reproductive medicine laboratories, the numbers of motile human sperm, the degree of sperm motility, and sperm morphology have been commonly analyzed using a microscope. It is challenging to monitor the health status of human sperm in resource-limited or remote settings for two primary reasons: (1) high capital cost (equipment for currently accepted procedural standard), and (2) complexity of the currently accepted procedural standard used to simultaneously measure human sperm concentration and motility by skillful embryologists. Determining the health status of human sperm in order to evaluate fertilization capacity using various types of low-cost, easy-to-use, and rapid devices (or systems) is a longstanding but interesting biotechnologically relevant issue in various scientific communities such as male reproduction. Furthering such efforts will inherently influence birth rate in both developed and developing nations. We have demonstrated an inexpensive but robust and easy-to-handle device for monitoring the health status of human sperm made by patterning a piece of paper and measuring the activity of a specific enzyme-a simple and elegant solution. After applying semen to the hydrophilic center circle of our patterned paper, a thiazine assay can be used to suggest sperm concentration in semen, and a tetrazolium-based colorimetric assay (MTT assay) data can be used to help estimate the percentage of motile human sperm (sperm motility) in semen based on the character that motile human sperm moved in and on the paper. Using this paper-based device, we can evaluate fertility levels without consulting doctors and use our assay to compare results with World Health Organization (WHO) reference values for sperm concentration (> 2×10(7)) and motility (> 50 %). The duration and cost of one entire test are 30 min and 0.1 USD, respectively. We believe that this paper-based assay system would be useful for fertility checks based on WHO references, without need of a microscope, at home. Using this assay method, males in developed or developing countries who are reluctant or unable to consult assisted reproductive technologies clinics can self-analyze their sperm characteristics. We further note that our approach adheres to WHO regulations, especially in regard to in vitro diagnostic device performance with an associated diagnostic algorithm to enhance diagnostic accuracy (compared with just one diagnostic output), and we wish to emphasize that our research could significantly advance a broad range of diagnostic developments including paper-based diagnostic devices, in vitro diagnostic devices, and diagnosis of other diseases in various divisions of translational medicine. These results, we believe, will be of interest to a wide scientific audience working in materials science (biomaterials), chemistry (analytical and clinical), lab-on-a-chip technologies (the development of diagnostic tools), reproductive medicine, bioengineering, and translational medicine.

Poorly soluble drugs: disbalance of thermodynamic characteristics of crystal lattice and solvation

The dissolution processes in aqueous media of poorly soluble drugs belonging to the classes of spiro derivatives, benzoic acid and its derivatives, sulfonamides, fenamates, and thiadiazoles were analyzed based on the data recently published by the author. The main criterion for the solubility analysis was the comparison of the thermodynamic characteristics of sublimation processes (state of the molecules in solids) and solvation (state of the molecules in solutions) under structural modification of the reference molecule. The characteristics of the processes under investigation were compared by the superposed diagram approach which allows complete information to be obtained about the thermodynamic state of the molecules in crystal and solution. A variety of thermodynamic paths of the molecules undergoing structural modification (design) was shown. The extreme solubility values were obtained for the considered classes of compounds which can be derived by structural modification of the substances. A classification of the drugs was suggested based on the analysis of the determinative steps of the dissolution processes: crystal or solvation controlled. Based on the investigation of 59 drugs belonging to five different classes of compounds, it was estimated that for 50.7% of the compounds the solubility processes were crystal controlled, whereas for the rest 49.3% – solvation controlled. Among all the considered compounds, a structural modification of the reference one led to a solubility enhancement only in 22.1% of the substances. And in 85% of the compounds, the dissolution processes were solvation controlled and in the remaining 15% – crystal controlled.

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.

Ring-contraction from benzo[b][1,4]thiazines to benzo[d]thiazolines induced by oxygen

An unexpected ring-contraction from benzo[b]pyrazino[1,2-d][1,4]thiazine-1,4-diones (6) to benzo[4,5] thiazolo[3,2-a]pyrazine-1,4-diones (7) has been developed. The preliminary mechanistic studies showed the transformation contained two independent steps: the first step is the formation of a Michael adduct upon the addition of the protic solvent, in the presence of base, to the C-2-C-3 double bond of compound 6, and the second step is a ring-contraction induced by oxygen via the migration of sulfur atom from C-2 to C-3 position.

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.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 6192-52-5. The above is the message from the blog manager. SDS of cas: 6192-52-5.
