Novel Thiazine Substituted 9-Anilinoacridines: Synthesis, Antitumour Activity and Structure Activity Relationships

Background: 9-anilinoacridines are acting as DNA-intercalating agents which plays an important role as antitumor drugs, due to their anti-proliferative properties. Some anticancer agents contain 9-anilinoacridines such as amsacrine (m-AMSA), and nitracrine (Ledakrine) have been already developed. Methods: In this study, novel 9-anilinoacridines substituted with thiazines 4a-r were designed, synthesized, characterized by physical and spectral data and their cytotoxic activities against DLA cell lines were evaluated. Results: Among those compounds, 4b, c, e, g, i, j, k, m, o, p, q, r exhibited significant short term in vitro cytotoxic activity against Daltons lymphoma ascites (DLA) cells with CTC50 value of 0.18 to 0.31 mu M. The compounds 4b, c, e, g, y j, k, m, o, p, q, r are also exhibited significant long term in vitro anti-tumour activity against human tumor cell lines, HEp-2 (laryngeal epithelial carcinoma) by Sulforhodamine B assay with CTC50 value of 0.20 to 0.39 mu M. The compounds 4b, i, j exhibited significant in vivo antitumor activity with % Increase in Life Span (ILS) 48-82%. Conclusion: Results obtained in this study clearly demonstrated that many of the thiazine substituted 9-anilinoacridines exert interesting anti-tumour activity. The compounds 4b, i, j have significant anti-tumour activity and useful drugs after further refinement. The above derivatives will encourage to design future antitumor agents with high therapeutic potentials.

In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 154445-78-0, Name is 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride, belongs to thiazines compound, is a common compound.

Pressure-Stabilized Solvates of Xylazine Hydrochloride

High pressure strongly favors the highest-density polymorph Z of active pharmaceutical ingredient 2-(2,6-xylidino)-5,6-dihydro-4H-1,3-thiazine hydrochloride (xylazine hydrochloride, XylHCl) up to about 0.1 GPa only, but still higher pressure destabilizes this structure. Above 0.1 GPa, XylHCl preferentially crystallizes as solvates with CH2Cl2, CHCl3, or (CH3)(2)CHOH depending on the solvent used. However, when XylHCl center dot H2O is dissolved in any of these solvents, the high-pressure crystallizations yield the hydrate XylHCl center dot H2O only. The single crystals of the CH2C12, CHCl3, and (CH3)(2)CHOH solvates could be grown in situ in a diamond anvil cell, which allowed their structure determination from the single-crystal diffraction data. At 0.4 GPa the XylHCl center dot H2O hydrate undergoes a pressure-induced phase transition doubling the unit cell dimensions.

Azaphenothiazines – promising phenothiazine derivatives. An insight into nomenclature, synthesis, structure elucidation and biological properties

For the last two decades, classical phenothiazines have attracted attention of researchers, as the hitherto investigations have revealed many significant biological activities within this class of compounds, other than originally discovered neuroleptic ones. Important, new pharmaceutical results on phenothiazines, as 10-substituted dibenzothiazines, were recently highlighted in several reviews. Azaphenothiazines are structurally modified phenothiazines by substitution of one or both benzene rings in the phenothiazine ring system with the azine rings, such as: pyridine, pyridazine, pyrimidine, pyrazine, 1,2,4-triazine, quinoline, quinoxaline, benzoxazine and benzothiazine. They form over 50 different heterocyclic systems, of tri-, tetra-, penta- and hexacyclic structures, and contain from one to even four azine nitrogen atoms. This review summarizes the methodical knowledge on azaphenothiazines, referring to their nomenclature, synthesis, structure analysis and above all significant varied biological activities, examined in vitro and in vivo. It describes, in addition, current trends in the synthesis of azaphenothiazines. The influence of the azaphenothiazine ring system, the nature of the substituents, predominantly at the thiazine nitrogen atom, as well as at the azine nitrogen atom and carbon atom, on the biological activities, were also discussed.

The title adduct, chlorido(2,3-diphenyl-3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one-kappa O) triphenyltin, [Sn(C6H5)(3)Cl(C16H15NOS)], resulted from reaction of 2,3-diphenyl- 3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one with triphenyltin chloride. The thiazine ring has an envelope conformation with the S atom forming the flap. The molecule has five phenyl rings, two of them attached to the thiazine ring at positions 2 and 3, and three in coordination with the Sn-IV atom. The three rings of the triphenyltin group are involved in intramolecular interactions of different types, C-H center dot center dot center dot O, edge-to-face (or T-type) pi-pi interactions with the 3-phenyl ring of the thiazine, T-type interactions with both phenyl rings of the thiazine etc. On the other hand, all the phenyl rings participate in intermolecular pi-pi interactions. There is one instance of a ‘parallel-displaced’-type interaction extending continuously along the a-axis direction and seven instances of T-type interactions stabilizing the crystal lattice.

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.

Photocatalytic degradations of three dyes with different chemical structures using ball-milled TiO2

Cibacron Brilliant Red 3B-A (BR 3B-A) was photocatalytically degraded by TiO2 (A) ball milled (BM) at different milling time. TiO2 (A) BM for 2 h (BM2 TiO2 (A)) showed the best photocatalytic degradation efficiency and was utilized to photcatalytically degrade commercial dyes of different chemical nature by breaking down the bond between chloride and the hydrocarbon chain. In the three dyes, i.e., Cibacron Brilliant Red BR 3B-A, Cibacron Brilliant Yellow 3G-P (BY 3G-P), and Astron Pink FG, chloride (Cl) is linked to carbon atom of different conformation. The experimental results suggested that the Cl connected to the aliphatic carbon is much easier and faster to disintegrate than the other two bonding with benzene and thiazine. Production rates of Cl- after 60-min irradiation were 99.7%, 78.1%, and 73.2%, respectively, for Astron Pink FG, BY 3G-P, and BR 3B-A. The changes in the structure characteristics, including the more amorphous surface morphology, the increased specific surface area, the growth in the percentage of high-index crystal faces, etc., were proposed to be the possible reasons for the promoted photocatalytic capability of BM2 TiO2 (A). Ball milling was found a handy approach to modify TiO2 (A) and boost catalytic degradation efficiency of dyes. This research lay out basis for application of photocatalyst in semiconductor industries.

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 5326-23-8. Application In Synthesis of 6-Chloronicotinic acid.
