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 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 the 1 : 1 adduct of 2,3-diphenyl-3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one with triphenyltin chloride

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.

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.
