Synthesis of antiaromatic thiazinoindolizines based on electrophilic cyclizations of indolizine-5-thione

Alkylation of indolizinethione at the sulfur atom by the action of RCOCH2Br (R = Me, Ar, CO2Me, OEt) leads to thioethers, and subsequent closure of the thiazine ring of which leads to the formation of stable antiaromatic thiazino[4,3,2-cd]indolizines.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 66-27-3. Formula: https://www.ambeed.com/products/66-27-3.html.

Radical cation and dication of a 4H-dithieno[2,3-b:3′,2′-e][1,4]-thiazine

A p-tert-butylphenyl substituted 4H-dithieno[2,3-b: 3′,2′-e][1,4] thiazine was synthesized by twofold Buchwald-Hartwig coupling. The electronic properties (UV/Vis, cyclic voltammetry and spectroelectrochemistry) and the DFT-and TD DFT-calculated electronic structure reveal that the parent system and the radical cation and dication oxidation products are highly polarizable p-systems with strong charge transfer contributions. The radical cation and the dication were prepared by oxidation with antimony(V) pentachloride, giving stable deeply colored salts. EPR spectroscopy of the radical cation furnishes hyperfine coupling constants with the nitrogen nucleus and the alpha-thienyl protons. The dication is EPR silent and was structurally characterized by recording an NMR spectrum.

Synthesis, characterization and in vivo evaluation of [Zn-62]-benzo-delta-sultam complex as a possible pet imaging agent

Objective The development of a new tracer based on the cyclic sulfonamides (sultams) was investigated. Methods 3-(Methoxy-phenyl-methyl)-1,6-dimethyl-1H benzo[c][1,2] thiazine 2,2-dioxide (benzo-delta-sultam) was synthesized and characterized by elemental analysis, FT-IR spectroscopy and single crystal X-ray structure determination. The prepared cyclic sulfonamide was labeled with non-commercial Zn-62 radioisotope for fast in vivo targeting and Coincidence imaging purposes (radiochemical purity 97 % ITLC, 96 % HPLC, specific activity 20-23 GBq/mmol). In vivo biodistribution of the final complex was investigated in Sprague Dawley (R) rats bearing fibro sarcoma tumor after 2, 4 and 8 h post injection and compared with free Zn+2 cation. Results Using instant paper chromatography method, the physicochemical properties of labeled compounds were found sufficiently stable in organic phases, e. g. a human serum, to be reliably used in bioapplications. Conclusions The complex exhibited a rapid as well as high tumor uptake (tumor to blood ratio 4.38 and tumor to muscle ratio 9.63) resulting in an efficient tumor targeting agent.

Synthesis, Characterization and Molecular Docking of Novel Bioactive Thiazolyl-Thiazole Derivatives as Promising Cytotoxic Antitumor Drug

Reactions of ethylidenethiocarbohydrazide with hydrazonoyl halides gave 1,3-thiazole or 1,3,4-thiadiazole derivatives according to the type of hydrazonoyl halides. Treatment of ethylidenethiosemicarbazide with hydrazonoyl halides and dimethylacetylene dicarboxylate (DMAD) afforded the corresponding arylazothiazoles and 1,3-thiazolidin-4-one derivatives, respectively. The structures of the synthesized products were confirmed by IR, H-1-NMR, C-13-NMR and mass spectral techniques. The cytotoxic activity of the selected products against the Hepatic carcinoma cell line (Hepg-2) was determined by MTT assay indicating a concentration dependent cellular growth inhibitory effect, especially for compounds 14c and 14e. The dose response curves indicated the IC50 (the concentration of test compounds required to kill 50% of cell population) were 0.54 M and 0.50 M, respectively. Confocal laser scanning imaging of the treated cells stained by Rhodamin 123 and Acridine orange dyes confirmed that the selected compounds inhibit the mitochondrial lactate dehydrogenase enzymes. The binding mode of the active compounds was interpreted by a molecular docking study. The obtained results revealed promising cytotoxic activity.

Facile synthesis of some condensed 1,3-thiazines and thiazoles under conventional conditions: antitumor activity

1,3-Thiazine 3 was obtained from cinnamoyl thiourea derivative 2 as the kinetic control product. Refluxing of 2 with sodium ethoxide afforded pyrimidine derivative 4. Moreover, stirring of 2 with bromine/acetic acid gave thiazole 5 that was condensed with o-phenylene diamine forming benzimidazole 6. Heating of arylthiourea 8 with maleic anhydride or phenacyl chloride afforded thiazole derivatives 9 and 10, respectively. Condensation of compound 10 with o-phenylene diamine gave benzimidazole 11. Reaction of p-amino benzoic acid with chloro acetyl isothiocyanate, acetylacetone and ethylacetoacetate produced imidazole 14, enaminone 15 and crotonate 16 derivatives, respectively. Stirring a mixture of benzoyl isothiocyanate with 15 and/or 16 resulted in pyridine-2-thione 17. The yields of the prepared compounds were 41-93%. The experimental section is simple and easy. The detailed synthesis, spectroscopic data, IC50 and antitumor activity of the synthesized compounds were reported. The cytotoxicity of the newly synthesized products showed that compound 4 is the most active compound towards the cancer cell line at which its reactivity is higher than that of the standard doxorubicin (anticancer reference drug).

Do we miss half of the injuries sustained during rape because we cannot see them? An overview of the use of toluidine blue tissue stain in the medical assessment of rape cases

The prosecution of rape cases is difficult due to the absence of eyewitnesses. McCauley found that the detection of vaginal lacerations increased from one in 24 to 14 in 24 in reported adult rape cases when toluidine blue was used. Proof of injuries consistent with sexual penetration adds significantly to the evidentiary value of the medico-legal testimony. Although rape is not a clinical diagnosis and there are no diagnostic criteria to confirm rape, the possibility of genital injury during rape far exceeds the possibility of injury with consensual intercourse. If a complete examination, including the use of toluidine blue, is not used a rapist may walk away to rape again, while the victims remain with the stigma that they may have made a false allegation.Toluidine blue is a basic thiazine metachromatic dye. It has a high affinity for acidic tissue components, thereby staining tissues rich in DNA and RNA. The epithelium of the external genitalia does not have nucleated cells and prevents contact of stain with nuclei. Where the epithelium is damaged and the underlying nucleated cells are exposed, the nuclei stain blue. Injuries sustained during genital penetration show a distinctive distribution.Toluidine blue stain is easy and safe to use, available, inexpensive and does not interfere with other medico-legal evidence, therefore it is recommended to be used in the examination of all cases of alleged rape.
