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.

Protonation-State-Driven Photophysics in Phenothiazinium Dyes: Intersystem Crossing and Singlet-Oxygen Production

The impact of altering the solvent pH value on the photodynamic activity of thionine has been studied computationally by means of density functional theory and multi-reference interaction methods. To this end, we have investigated the electronic structure of the ground and excited states of diprotonated (TH22+) and neutral imine (T) forms of thionine (TH+). It is well known experimentally that the T-1 state of TH+ undergoes acid-base equilibrium reactions resulting in a pronounced pH effect for the efficiency of singlet-oxygen (O-1(2)) production. Our results show that the energy-transfer reactions from the T-1 state of TH22+ and T to O-3(2) correspond to reversible equilibrium processes, whereas in TH+ this process is very exothermic in a vacuum (-0.66 eV) and in aqueous solution (-0.49 eV). These facts explain the experimental observation of a much smaller efficiency of O-1(2) production for TH22+ than for TH+. Moreover, we found that the pH value significantly effected the intersystem crossing (ISC) kinetics impacting the concentration of triplet-state species available for energy transfer. In very acidic aqueous solution (pH < 2) where TH22+ is the prevailing species, the ISC proceeds with a rate constant of approximate to 10(8) s(-1). In a basic medium where T is the dominant species, ISC decay occurs by means of a thermally activated channel (approximate to 10(8)s(-1)) which competes with fluorescence (5.32 x 10(7) s(-1)). According to these results, maximum ISC efficiency is expected for intermediate acidic pH values (TH+, approximate to 10(9) s(-1)).

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.

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.
