A New Sustainable Strategy for Synthesis of Novel Series of Bis-imidazole and Bis-1,3-thiazine Derivatives

An expeditious, eco-friendly, and efficacious protocol was achieved for the preparation of bis-imidazoles and bis-1,3-thiazines from the reaction of tetracyanoethylene with dialdehydes or bis-thiosemicarbazones, respectively. Merely mixing and sonicating the starting materials furnishes the desirable products in considerable yields. This reaction smoothly proceeded and presented many merits, over conventional and mechanochemical approaches, including simple experimental workup procedure, no by-products, and short reaction time. Moreover, the protocol scoring admirably in various green metrics, as a consequence, shows these approaches to be an ideal sustainable and green process.

Cytochathiazines A-C: Three Merocytochalasans with a 2H-1,4-Thiazine Functionality from Coculture of Chaetomium globosum and Aspergillus flavipes

Cytochathiazines A-C (1-3), which represent a new type of merocytochalasan, were isolated from coculture of Chaetomium globosum and Aspergillus flavipes. Compounds 1-3 are the first natural products featuring an unprecedented 2H-1,4-thiazine functionality. Plausible biosynthetic pathways for 1-3 with a chaetoglobosin and a dipeptide as the main constitutional units were proposed. Compound 2 induced apoptosis in leukemia cells through the activation of caspase-3 and the degradation of poly ADP-ribose polymerase.

Synthesis and In Vitro Anticancer Evaluation of Symmetrically Bridged 1,3-thiazine Derivatives

A series of bis-1,3-thiazine derivatives 3a-o were synthesized from the condensation reactions of symmetric dialdehydes 1a-c possessing aliphatic ether spacer units with 3-substituted-amino-2-cyano-3-mercaptoacrylamides 2a-e. The chemical structures of the products were fully characterized by using different spectroscopic techniques, such as H-1 NMR, C-13 NMR, IR, electron impact mass spectrometry, and elemental analysis. Compounds 3a, 3f, and 3k underwent ring opening followed by recyclization and alkylation in basic medium to afford bis-pyrimidinones 4a-c and 5a-c. The anticancer potential of the new bis-1,3-thiazines was assessed in vitro against six different human cell lines, including lung A549, colon HCT116, breast MCF-7, prostate PC3, liver HepG2, and normal melanocyte HFB4. The results revealed a potent activity of compounds 3e and 3k against breast and liver cancer cell lines in comparison with the reference drug doxorubicin with no noticeable toxicity on normal cells.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 20277-69-4, in my other articles.

Synthesis and L-type calcium channel blocking activity of new chiral oxadiazolothiazinones

Oxadiazolo[3,4-c][1,4]thiazin-3-ones are cardiovascular agents that block L-type calcium channels. Previous data of cardiac and vasorelaxant activity on guinea-pig for several derivatives indicated the two positions ortho to the thiazine’s sulphur as crucial for modulating the activity; but these positions are likely susceptible to metabolic biotransformations, as indicated by in silico predictions. We designed new derivatives, and obtained three negative inotropic agents with EC50 in the low nanomolar range, more potent than all the precursors published so far. In particular, benzocondensation at the thiazine ring led to 3a (EC50 = 0.013 mu M) and 3b (EC50 = 0.006 mu M). Besides negative inotropy, we also observed relaxant activity on nonvascular muscle in the micromolar range. We resolved the new derivatives by chiral chromatography, and determined their absolute configuration by comparing experimental and calculated chiroptical properties (VCD, ECD and ORD): they hold the same absolute configuration-optical rotation relationship, (S)-(+)I(R)-(-). Both cardiac and nonvascular activity are majorly or mostly retained in the R-form for all the compounds, but for the nonvascular activity we observed a strong stereoselectivity for 3a, with the R-form in the nanomolar range (IC50 = 0.020 mu M) and 259-fold more potent than the S-one.

Synthesis and Intramolecular Cyclization of N-acyl- and N-allyl-N ‘-(2-oxo-1,2-dihydro-pyridin-3-yl)thiourea

The reaction of 3-amino-4,6-dimethylpyridin-2(1H)-one and 3-amino-4-phenylpyridin-2-one with acyl isothiocyanates (benzoyl-, 4-bromobenzoyl-, and methacryloyl isothiocyanates) and with allyl isothiocyanate has been studied. The N-carbamothioyl methacrylamides and N-allylthioureas obtained undergo intramolecular heterocyclization reactions to give the corresponding 1,3-thiazin-4-one and 1,3-thiazoline derivatives. It was found that the starting 3-amino-4,6-dimethylpyridin-2(1H)-one shows antiradical activity but the synthesized thioureas do not.

Crystal structure of (E)-2-benzylidene-4-[(3-phenyl-4,5-dihydroisoxazol-5-yl)-methyl]-2H-benzo[b][1,4] thiazin-3(4H)-one

In the title compound, C25H20N2O2S, the dihydroisoxazole ring exhibits an envelope conformation with the methine atom being the flap, while the 1,4-thiazine ring displays a screw-boat conformation. The six-membered ring fused to the 1,4-thiazine ring makes dihedral angles of 63.04 (2) and 54.7 (2)degrees with the mean planes through the five-membered heterocycle and the attached phenyl ring, respectively. The phenyl group connected to the 1,4-thiazine ring is disordered over two sites [major component = 0.57 (2)]. The most prominent interactions in the crystal structure are C-H center dot center dot center dot O hydrogen bonds that link molecules, forming inversion dimers, and C-H center dot center dot center dot N hydrogen bonds that link the dimers into columns parallel to the b axis.

A synergistic catalysts system ZnO NPs and Malic acid was used for the highly efficient and eco-friendly synthesis of oxazines and thiazines derivatives. Aldehyde, urea and alkyne derivatives are used as reactants under ultrasonication, which not only allows clean and rapid alteration but also simplifies experimental setup. High yields, environmentally benigness, simple work-up and shorter reaction times are some remarkable advantages of this strategy. (C) 2019 Elsevier B.V. All rights reserved.
