Determination of Lipophilicity of Allyl Thiosemicarbazide, N-1-Thiocarbamylamidrazone Derivatives, and their Cyclic Products by RP-HPLC, RP-TLC, and Theoretical Methods: Effects of Selected Compounds on the CNS of Mice

The allyl thiosemicarbazide, N-1-thiocarbamylamidrazone derivatives, and the products of their cyclization: the 1,2,4-triazole, 1,3,4-thiadiazole, 1,2,4-triazole[3,4-b]1,3-thiazine, 1,2,4-triazole[3,2-b]1,3-thiazine, 1,3,4-thiadiazole[3,2-a]pyrimidine, 5,6-dihydrothiazolo[2,3-c][1,2,4]triazole, and benzoic acid derivatives have been analyzed by RP-HPLC and RP-TLC methods using the methanol-water mixtures as the mobile phase and the octadecyl stationary phase. The lipophilicity was expressed as the chromatographically derived descriptors: mean of k(mk), mean of logk (mlogk), logk(W), S, and phi(0), scores of k, logk, and R-M corresponding to the first principal component. Additionally, the authors propose to introduce a descriptor (logk(m)) corresponding to the residual specific interactions. Chromatographic parameters of lipophilicity were compared with the partition coefficient (logP) calculated by various softwares (milogP, clogP, AlogPs, AClogP, AlogP, MlogP, KOWWIN, XlogP2, XlogP3). The matrices were created with logk(W) or R-MW and logP and they have been the subject of PCA analysis. The effects of the selected compounds on the central nervous system (CNS) of mice were studied.

Regional Anesthesia for Dentistry and Orofacial Surgery in Rhesus Macaques (Macaca mulatta)

Regional anesthesia is a commonly used adjunct to orofacial dental and surgical procedures in companion animals and humans. However, appropriate techniques for anesthetizing branches of the mandibular and maxillary nerves have not been described for rhesus monkeys. Skulls of 3 adult rhesus monkeys were examined to identify relevant foramina, establish appropriate landmarks for injection, and estimate injection angles and depth. Cadaver heads of 7 adult rhesus monkeys (4 male, 3 female) were then injected with thiazine dye to demonstrate correct placement of solution to immerse specific branches of the mandibular and maxillary nerves. Different volumes of dye were injected on each side of each head to visualize area of diffusion, and to estimate the minimum volume needed to saturate the area of interest. After injection, the heads were dissected to expose the relevant nerves and skull foramina. We describe techniques for blocking the maxillary nerve as well as its branches: the greater palatine nerve, nasopalatine nerve, and infraorbital nerve. We also describe techniques for blocking branches of the mandibular nerve: inferior alveolar nerve, mental (or incisive) nerve, lingual nerve, and long buccal nerve. Local anesthesia for the mandibular and maxillary nerves can be accomplished in rhesus macaques and is a practical and efficient way to maximize animal welfare during potentially painful orofacial procedures.

One-Pot Three-Component Synthesis and Molecular Docking of Some Novel 2-Thiazolyi Pyridines as Potent Antimicrobial Agents

Background: Thiazoles and pyridines are versatile synthetic scaffolds possessing wide spectrum of biological effects including potential antimicrobial activity. Objective: In the efforts to develop suitable antimicrobia drugs, medicinal chemists have focused on thiazole derivatives. A novel series of 2-thiazolyl pyridines was prepared in a one pot three-component reaction using 2-bromoacetyl pyridine as a starting precursor. Method: Structure of the synthesized compounds was elucidated by spectral data (FT-IR, H-1 NMR, C-13 NMR, and mass) and elemental analyses. The prepared compounds were screened for their in vitro antimicrobial activity. Results: The results revealed that compounds 4a,b,e-g and 12 showed promising activity. Molecular docking studies using MOE software were carried out for compounds 4a and 4b which exhibited potent activities indicated by the diameter zones (4a; 3.6, 4.0, 1.2 mm) (4b; 4.2, 3.5, 1.5 mm) and the binding affinities (4a; -5.7731, -5.3576, -4.6844 kcal mol(-1)) (4b; -5.9356, -2.8250, -5.3628 kcal mol(-1)) against Candida albicans, Bacillus subtilis and Escherichia coli, respectively. Conclusion: This paper describes a facile and efficient MCR for synthesis of 2-thiazolyl pyridines from reaction of 2-bromoacetyl pyridine with different reagents. There was an agreement between the values of binding affinities and interactions and the data obtained from the practical antimicrobial screening of the tested compounds.

Characterization of biogenically synthesized silver nanoparticles for therapeutic applications and enzyme nanocomplex generation

The present study describes green synthesis of silver nanoparticles (AgNPs) and inulin hydrolyzing enzyme nanocomplexes (ENC) usingAzadirachta indica(Ai) andPunica granatum(Pg) leaf extracts. Surface topology and physico-chemical characteristics of AgNPs were studied using surface plasmon resonance (SPR), FTIR, SEM, AFM and EDX analyses. Particle size analysis using dynamic light scattering and AFM studies revealed thatAi-AgNPs (76.4 nm) were spherical in shape having central bigger nano-regime with smaller surroundings whilePg-AgNPs (72.1 nm) and ENCs (Inulinase-Pg-AgNPs similar to 145 nm) were spherical particles having smooth surfaces.Pg-AgNPs exhibited significant photocatalysis of a thiazine dye, methylene blue. BothAi-andPg-AgNPs showed selective antibacterial action by inhibiting pathogenicBacillus cereus, while the probioticLactobacillusstrains remained unaffected.Ai-AgNPs showed potential anti-biofilm effect (30% viability) onB. cereusbiofilms.Pg-AgNPs showed anti-cancer effect against human colon cancer cell lines (Caco-2) resulting in 40% cell death in 48 h. Enzymes (inulinase, L-asparaginase and glucose oxidase) were successfully immobilized onto nanoparticles together with the biogenic synthesis of AgNPs and recyclability of the Inulinase-Pg-AgNPs complex was demonstrated. The study elaborates characteristics of green synthesized nanoparticles and their potential applications as anti-cancer, antibacterial and antioxidant nano drugs that could be used in food and nutraceutical industries. Enzyme immobilization on AgNPs without any toxic cross-linker opens up newer possibilites in enzyme-nanocomplex research.

Cyclization of N-benzyl cyanoacetamide: Novel synthesis and biological activity of pyrrole, pyrimidine, and pyran derivatives

Heteroannulation of N-Benzyl cyanoacetamide 1 to a new series of heterocycles has been developed. Thus, reaction of 1 with different polarized pi systems afforded pyrrolo 4, pyridone 6, pyridine 8, and diazapene 10 derivatives, respectively. N-Benzyl cyanoacetamide that undergo condensation reaction with salicylaldehyde yielded pyran derivative 11. Nitrosation of 11 furnished condensed pyran 13. Compound 11 reacted with benzaldehyde, carbon disulfide (cyclizing agent), and ammonium thiocyanate to provide pyrane 17, thiazine 18, and thiourea 20 derivatives, respectively. Cinnamoyl isothiocyanate was reacted with compound 11 to produce non-isolable thiourea derivative 21. The newly synthesized compounds have been characterized by infrared (IR), proton nuclear magnetic resonance (H-1 NMR), and carbon nuclear magnetic resonance (C-13 NMR) spectral data. The compounds were then evaluated for antibacterial and anticancer activities.

Crystal structure of cyclic sulfin- and sulfonamides of the thiazine series: Conformation, intra- and intermolecular interactions

An X-ray crystallographic study of a new compound is performed and the structure of five sulfin- and sulfonamides of the thiazine series is discussed. The conformation of the thiazine ring in all structures (a distorted boat) is stabilized by the intramolecular interaction of the C-HaEuro broken vertical bar N type. The nitrogen atom of the thiazine ring has a pyramidal configuration. The geometry of isolated molecules is calculated at density functional theory level (PBE1PBE, 6-31G(d,p)) and compared to that observed in the crystals. In the crystal structures different packing motifs are implemented with the formation of supramolecular associates of different types due to classical hydrogen bonds such as N-H center dot center dot center dot O.

Alkylation of 5-(3-chlorobenzo[b]thien-2-yl)-1,2,4-triazole-3-thione with Epichlorhydrin and the Role of MW and Solid Support in the Reaction

An efficient eco-friendly approach has been adopted for the selective synthesis of 2,3-epoxypropylsulfanyltriazole 4 from the reaction of 1-chloro-2,3-epoxy-propane (2) with 5-(3-chlorobenzo[b]thien-2-yl)-4H-1,2,4-triazole-3-thione (1) under solvent free microwave conditions in the presence of a solid support. Instead, when the mixture of reactants was irradiated for prolonged time in the absence of solid support, triazolo[2,1-b]thiazine 3 was exclusively afforded in excellent yield. On the other hand, performing the irradiation in the presence of a base, mixtures of compounds 4 and 3 were obtained; the ratio of the two products was dependent on the nature of the base, although 4 was the major product in each case.

Synthesis, spectroscopic structure identification, X-ray study and anticancer activities of new angularly fused quinobenzothiazines

Synthesis of 16 new tetracyclic angularly fused azaphenothiazines, 8-, 9- and 10-substituted quinobenzo1,4-thiazines (benzo[a]-3-azaphenothiazines) was based on the reactions of dichlorodiquinolinyl disulfide and diquinodithiin with substituted anilines. Whereas the reactions with p-fiuoroaniline and p-methylthioaniline led to only one product, the reaction with m-triflouromethylaniline led to isomeric compounds. The obtained 8-10-substituted 12H-quinobenzothiazines were further transformed into 12 substituted derivatives through allcylation of the thiazine nitrogen atom. The structure analysis was based on 1D and 2D NMR (NOESY, COSY, HSQC and HMBC) spectra which enabled to distinguish the isomers and to exclude retro-Smiles rearrangement and the azine nitrogen atom alkylation pathways. This supposition was fully confirmed by X-ray analysis showing the quinobenzothiazine system to be folded and the substituent at the thiazine nitrogen atom in an equatorial position. Some compounds exhibited anticancer activity against MCF-7, MDA-MB-231 and SNB-19 cell lines similar to a reference drug cisplatin. The structure-activity relationship of the compounds were discussed. (C) 2016 Elsevier B.V. All rights reserved.

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.
