Synthesis and biological evaluation of novel pyrimidines derived from 6-aryl-5-cyano-2-thiouracil

Starting from 6-aryl-5-cyano-2-thiouracil derivative 1a-f, a series of novel thiazolo[3,2-a] pyrimidines 4a-f were synthesized. The mechanism and the regioselectivity of the studied reactions are discussed. In addition, a series of tetrahydro-4-H-pyrimido[2,1-b][1,3] thiazines 7a-e and 2-((ethoxymethyl)thio)-4-aryl-1,6-dihydropyrimidines 9b,c,e were synthesized. The anti-microbial activities of some of the prepared compounds were screened, and the results revealed that compounds 3c and 4c were more active than the standard (Ampicillin) against gram positive bacteria (Pseudomonas aeruginosa). Moreover, compounds 4b,e and 3f were found to be good antifungal agents against the studied fungal strains.

Spectral and kinetic features of nonradiative energy transfer in hybrid associates of colloidal quantum dots and organic dyes

The features of nonradiative resonance energy transfer in hybrid associates of colloidal CdS quantum dots (QDs) with molecules of a thiazine dye and J-aggregates of a carbocyanine dye are discussed. The case of an inhomogeneously broadened recombination band of donor (CdS QDs) luminescence is considered. We detected spectral-selective quenching of recombination luminescence of colloidal CdS QDs in association with organic dyes. The maximum of quenching occurs in the region of absorption of the acceptor (organic dye molecule). It is shown using the time-correlated single photon counting technique that the lifetime of the QD luminescence decreases synchronously with the quenching of the luminescence, but only at the wavelengths falling in the region of absorption of the dye. Based on the concept of a donor-acceptor nature of emission of CdS QDs, the dependence of the efficiency of nonradiative energy transfer on the luminescence wavelength is analyzed taking into account the Poisson distribution of its quenchers.

Copper(I)-Catalyzed Oxidative Coupling between 2-Aminobenzothiazole and Terminal Alkyne: Formation of Benzothiazine

An unprecedented formation of benzothiazine during copper(I)-catalyzed oxidative coupling of 2-aminobenzothiazole and terminal alkyne in air has been observed. This unique transformation possibly occurs through the ring opening of 2-aminobenzothiazole and subsequent oxidative coupling with alkyne followed by intramolecular cyclization. A variety of substituted benzo[b][1,4]thiazine-4-carbonitriles are obtained by this protocol.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 154445-78-0, you can contact me at any time and look forward to more communication. Category: thiazines.

Synthesis of 6-Alkylidene-5,6-dihydro-4H-1,3-thiazine Derivatives via the Cyclization of N-3-Bromo-3-alkenylthioamides

By the treatment of N-3-bromo-3-alkenylthioamides with sodium hydroxide in DMF-H2O in the presence of tetra-butylammonium bromide, series of 6-alkylidene-5,6-dihydro-4H-1,3-thiazine derivatives were prepared in moderate to good yields. The cyclization is supposed to proceed via both the intramolecular vinylic nucleophilic substitution and the elimination-addition mechanisms (formation of acetylenic intermediates) in a competitive manner.

Nonlinear absorption of some thiazine, xanthene, and carbocyanine dyes

The saturated and two-photon absorption of various classes of heterocyclic dyes [thiazine (thionine), xanthene (erythrosine), and carbocyanine (3,3′-di-(gamma-sulfopropy1)-4,4′,5,5′-dibenzo-9-ethylthiacarbocyaninebetaine pyridinium salt, DEC)] possessing optical absorption in the 500-680 nm range were measured at the wavelengths of 1064 and 532 nm using nanosecond (10 ns) and picosecond (40 ps) pulses and z-scan technique. It was shown that reverse saturated absorption unlikely plays important role in those dyes. We defined the two-photon absorption coefficients of thionine and erythrosine at 1064nm using 40 ps pulses (0.8 x 10(-11) and 1.0 x 10(-11) cmW(-1) respectively). The concurrence of saturated absorption and two-photon absorption was analyzed in the case of thionine and erythrosine using various models. It was suggested that dimerization of those dyes significantly suppresses the nonlinear optical response in the case of both 10 ns and 40 ps pulses of 532 nm radiation. At the same time it was found that, in the case of 532 nm pulses, the monomers of thionine participate in the processes of saturated absorption and two-photon absorption, while J-aggregates of DEC show predominantly two-photon absorption.

Modular synthesis and transition metal-free alkynylation/alkenylation of Castagnoli-Cushman-derivedN,O- andN,S-heterocyclic vinyl chlorides

A modular and functional group-tolerant protocol for the transition metal-free coupling of novelN,O- andN,S-heterocyclic vinyl chlorides with terminal acetylenes and styrenes has been developed, leading to the epimerization-free synthesis of fully carbofunctionalized dihydro-1,4-oxazines/thiazines. Bicyclic morpholines have also been prepared through the interrogation of newly synthesized cross-conjugated dienes in Diels-Alder reactions. The use of environmentally benign reaction media endows the current strategy with a practical advantage.

Halogenated phenotiazine as photoantimicrobial agent against Staphylococcus aureus. Evaluation of the vehiculization in polymeric nanoparticles

A thiazine derivative of AzB, the monoiodinated Azure B (AzBI), was designed, characterized, chemical and photochemically evaluated, and screened for antibacterial activity. The monoiodinated derivative showed better chemical and photochemical properties compared to the leading compound Azure B (AzB). Also, AzBI exhibited good antibacterial activity against methicillin-sensitive Staphylococcus aureus (MSSA) ATCC 29213 and methicillin-resistant S. aureus (MRSA) ATCC 43300. The assayed compound represents a promising structure for the development of a new synthetic photosensitizer with improved properties and biological activity. Based on the results obtained for AzBI, this compound was loaded in the polymeric nanoparticles synthesized by our working group in order to improve some of its physicochemical properties. In this way, it was possible to successfully load the monoiodinated derivative and yield a promising drug transport system. The latter presented better characteristics and antimicrobial activity than AzBI against the different strains tested. All these results make AzBI an excellent candidate for application in photodynamic therapy.
