Internal heavy atom effects in phenothiazinium dyes: enhancement of intersystem crossing via vibronic spin-orbit coupling

The effect of substituting the intra-cyclic sulphur of thionine by oxygen (oxonine) and selenium (selenine) on the intersystem crossing (ISC) efficiency has been studied using high level quantum mechanical methods. The ISC rate constants are considerably increased when going from O towards Se while the fluorescence rate constants remain unchanged. For the three dyes, all accessible ISC channels are driven by vibronic spin-orbit coupling (SOC) between pi pi* states. The interplay between the ground and low-lying excited states has been investigated in order to determine the dominant relaxation pathways. In oxonine the relaxation to the ground state after photoexcitation in water proceeds essentially via fluorescence from the S-1(pi(H)pi(L)*) bright state (k(F) = 2.10 x 10(8) s(-1)), in agreement with the high experimental fluorescence quantum yield. In aqueous solution of thionine, the ISC rate constant (k(ISC) similar to 1 x 10(9) s(-1)) is one order of magnitude higher than fluorescence (k(F) = 1.66 x 10(8) s(-1)) which is consistent with its high triplet quantum yield observed in water (phi(T) = 0.53). Due to a stronger vibronic SOC in selenine, the ISC rate is very high (k(ISC) similar to 10(10) s(-1)) and much faster than fluorescence (k(F) = 1.59 x 10(8) s(-1)). This suggests selenine-based dyes as very efficient triplet photosensitizers.

Methylene blue induces the soxRS regulon of Escherichia coli

Extensive application of methylene blue (MB) for therapeutic and diagnostic purposes, and reports for unwanted side effects, demand better understanding of the mechanisms of biological action of this thiazine dye. Because MB is redox-active, its biological activities have been attributed to transfer of electrons, generation of reactive oxygen species, and antioxidant action. Results of this study show that MB is more toxic to a superoxide dismutase-deficient Escherichia coli mutant than to its SOD-proficient parent, which indicates that superoxide anion radical is involved. Incubation of E. coli with MB induced the enzymes fumarase C, SOD, nitroreductase A, and glucose-6-phosphate dehydrogenase, all controlled by the soxRS regulon. Induction of these enzymes was prevented by blocking protein synthesis with chloramphenicol and was not observed when soxRS-negative mutants were incubated with MB. These results show that MB is capable of inducing the soxRS regulon of E. coli, which plays a key role in protecting bacteria against oxidative stress and redox-cycling compounds. Irrespective of the abundance of heme-containing proteins in living cells, which are preferred acceptors of electrons from the reduced form of MB, reduction of oxygen to superoxide radical still takes place. Induction of the soxRS regulon suggests that in humans, beneficial effects of MB could be attributed to activation of redox-sensitive transcription factors like Nrf2 and FoxO. If defense systems are compromised or genes coding for protective proteins are not induced, MB would have deleterious effects.

Synthesis and Investigation of Pinane-Based Chiral Tridentate Ligands in the Asymmetric Addition of Diethylzinc to Aldehydes

A library of pinane-based chiral aminodiols, derived from natural (-)-beta-pinene, were prepared and applied as chiral catalysts in the addition of diethylzinc to aldehydes. (-)-beta-Pinene was reacted to provide 3-methylenenopinone, followed by a reduction of the carbonyl function to give a key allylic alcohol intermediate. Stereoselective epoxidation of the latter and subsequent ring opening of the resulting oxirane with primary and secondary amines afforded aminodiols. The regioselectivity of the ring closure of the N-substituted secondary aminodiols with formaldehyde was examined and exclusive formation of oxazolidines was observed. Treatment of the allylic alcohol with benzyl bromide provided the corresponding O-benzyl derivative, which was transformed into O-benzyl aminodiols by aminolysis. Ring closure of the N-isopropyl aminodiol derivative with formaldehyde resulted in spirooxazolidine. The obtained potential catalysts were applied in the reaction of both aromatic and aliphatic aldehydes to diethylzinc providing moderate to good enantioselectivities (up to 87% ee). Through the use of molecular modeling at an ab initio level, this phenomenon was interpreted in terms of competing reaction pathways. Molecular modeling at the RHF/LANL2DZ level of theory was successfully applied for interpretation of the stereochemical outcome of the reactions leading to display excellent (R) enantioselectivity in the examined transformation.

Microwave-assisted Solid-phase Synthesis of N-substituted-2-aminobenzo[d][1,3] Thiazine Derivatives from a BOMBA Resin

An efficient solid-phase methodology has been developed for the synthesis of N-acyl and N-sulfonyl substituted 2-aminobenzo[d][1,3] thiazine derivatives. The key step in this methodology is the preparation of backbone amide linker-bound 2-aminobenzo[d][1,3] thiazine resin through cyclization reaction between isothiocyanates and BOMBA resin under microwave irradiation. This 2-aminobenzo[d][1,3] thiazine core skeleton resin undergoes substitution reactions with various electrophiles, such as acid halides and sulfonyl halides, to generate N-acyl and N-sulfonyl substituted 2-aminobenzo[d][1,3] thiazine resins, respectively. Finally, N-acyl and N-sulfonyl-substituted 2-aminobenzo[d][1,3] thiazine derivatives are prepared in good yields and purities by cleavage of the respective resins under trifluoroacetic acid (TFA) in dichloromethane (DCM).

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 196597-78-1. SDS of cas: 196597-78-1.

Molecular Docking and Receptor-Based 3D-QSAR Studies on Aromatic Thiazine Derivatives as Selective Aldose Reductase Inhibitors

Aromatic thiazine derivatives were proved to be potent aldose reductase inhibitors (ARIs) with high selectivity for aldose reductase (ALR2) over aldehyde reductase (ALR1). Molecular docking and three-dimensional quantitative structure-activity relationship (3D-QSAR) studies are conducted on a dataset of 44 molecules to explore the interactions between aromatic thiazine derivatives and ALR2. The superposition of ALR2 and ALR1 active sites indicate that residues Leu 300 and Cys 298 from ALR2 may explain the good selectivity of the most active compound 1m. The comparative molecular field analysis (CoMFA) model (q(2) = 0.649, r(2) = 0.934; q(2): cross-validated correlation coefficient, r(2): non-cross-validated correlation coefficient) and comparative molecular similarity indices analysis (CoMSIA) model (q(2) = 0.746, r(2) = 0.971), based on the docking conformations of these compounds, are obtained to identify the key structures impacting their inhibitory potencies. The predictive power of the developed models is further validated by a test set of seven compounds, resulting in predictive r(Pred)(2) values of 0.748 for CoMFA and 0.828 for CoMSIA. 3D contour maps, drawn from 3D-QSAR models, reveal that future modifications of substituents at the C3 and C4 positions of the benzyl ring and the C5 and C7 positions of the benzothiazine-1,1-dioxide core might be favorable for improving the biological activity, which are in good accordance with the C7 modification results reported in our earlier work. The information rendered by 3D-QSAR models could be helpful in the rational design of novel ARIs with good inhibitory activity to treat diabetic complications in the future.
