A Facile and Chemoselective Synthesis of Novel Pyrimido[5,4-b][1,4]thiazines by exo-dig Iodocyclization Reactions

The present manuscript involves the synthesis of 5-prop-2-ynylsulfanyl-pyrimidin-4-ones 3a-i by [4+2] cycloaddition reactions of 1,3-diazabuta-1,3-dienes 1a-i with prop-2-ynyl-sulfanyl ketene 2. These 5-prop-2-ynylsulfanyl-pyrimidin-4-ones 3a-i were explored in iodocyclization for the synthesis of novel pyrimido[5,4-b][1,4]thiazines 4a-i in excellent yields. The iodocyclizations followed exo-dig ring-closure cyclizations to yield 6-6 bicyclic fused pyrimidinones, while corresponding endo-dig ring-closure iodoamination was not observed.

I am very proud of our efforts over the past few months and hope to 92-39-7 help many people in the next few years. 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.

Synthesis and biological evaluation as well as in silico studies of arylpiperazine-1,2-benzothiazine derivatives as novel anti-inflammatory agents

Novel arylpiperazine-1,2-benzothiazine derivatives have been designed and synthesized as potential antiinflammatory agents. Their structure and properties have been studied using spectroscopic techniques (H-1 NMR, C-13 NMR, FT-IR), MS, elemental analyses, and single-crystal X-ray diffraction (SCXRD, for compound 7b). This study aimed to evaluate the inhibitory activity of new derivatives against both cyclooxygenase isoforms COX-1 and COX-2 due to the similarity of new compounds to oxicams drugs from the NSAIDs group. All new compounds were divided into two series – A and B – with a different linker between thiazine and piperazines nitrogens. Series A included the three-carbon aliphatic linker and series B – two-carbon with a carbonyl group. According to in vitro and molecular docking studies all new compounds exhibited cyclooxygenase inhibitory activity. The series of A compounds included COX-1 inhibitors only. In contrast, the B series showed inhibition of both COX-1 and COX-2, which suggested the importance of the acetoxy linker for COX-2 inhibition. Moreover, the most selective compound 7b, towards COX-2, was non-toxic for the normal human cell line (in concentration of 10 mu M) comparable to reference drug meloxicam. Additionally, investigation of influence on model membranes confirmed the ability of the compound 7b to penetrate lipid bilayers which seemed to be important to the influence with membrane protein-cyclooxygenase.

Sublimation enthalpy of 1,3-thiazine structural analogues: Experimental determination and estimation based on structural clusterization

The saturated vapor pressures of 4 nonaromatic bicyclic 1,3-thiazine and 1,3-selenazine derivatives have been measured by the method of transpiration by inert gas-carrier in the temperature range of 308-392 K. Based on the experimental data the thermodynamic functions of sublimation have been calculated. The sublimation enthalpies of the compounds vary from 104 to 150 kJ mol(-1) depending on the chemical nature of the substituent in the aryl moiety and the heteroatom in the bicyclic fragment. The crystal lattice energy of thiazines decreases with the introduction of substituents in the following order: cyano > acetyl > isopropyl. New approach has been suggested to evaluating sublimation enthalpy of the studied and structurally related compounds by using clusterization of the space of experimental points.

The first observation on polymerization of 1,3-benzothiazines: synthesis of mono- and bis-thiazine monomers and thermal properties of their polymers

A monofunctional 1,3-benzothiazine (PH-a-BZT) has been synthesized by a method different from the one reported in the literature. Additionally, a difunctional version of 1,3-benzothiazine (PH-ddm-BZT) monomer has been synthesized. Polymerization of mono- and bis-thiazine monomers has been studied and confirmed for the first time. The two monomers are characterized with proton and carbon nuclear magnetic resonance spectroscopy (H-1-NMR, C-13-NMR) along with Fourier transform infrared (FT-IR) spectroscopy. The cross-linked polybenzothiazine which is derived from the bis-thiazine monomer shows excellent thermal properties as examined by thermogravimetric analysis (TGA). Polybenzothiazine is developed in hopes that it could mimic many of benzoxazine’s popular attributes while containing sulfur in place of oxygen atoms. It can also possess unique advantages such as higher flame retardancy and adhesiveness to the metal substrate than polybenzoxazine due to the characteristic sulfur atom in its polymer.

Synthesis and Antimicrobial Activity of 1,2-Benzothiazine Derivatives

A number of 1,2-benzothiazines have been synthesized in a three-step process. Nine chalcones 1-9 bearing methyl, fluoro, chloro and bromo substituents were chlorosulfonated with chlorosulfonic acid to generate the chalcone sulfonyl chlorides 10-18. These were converted to the dibromo compounds 19-27 through reaction with bromine in glacial acetic acid. Compounds 19-27 were reacted with ammonia, methylamine, ethylamine, aniline and benzylamine to generate a library of 45 1,2-benzothiazines 28-72. Compounds 28-72 were evaluated for their antimicrobial activity using broth microdilution techniques against two Gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus) and two Gram-negative bacteria (Proteus vulgaris and Salmonella typhimurium). The results demonstrated that none of the compounds showed any activity against Gram-negative bacteria P. vulgaris and S. typhimurium; however, compounds 31, 33, 38, 43, 45, 50, 53, 55, 58, 60, 63 and 68 showed activity against Gram-positive bacteria Bacillus subtilis and Staphylococcous aureus. The range of minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was 25-600 mu g/mL, though some of the MIC and MBC concentrations were high, indicating weak activity. Structure activity relationship studies revealed that the compounds with a hydrogen atom or an ethyl group on the nitrogen of the thiazine ring exerted antibacterial activity against Gram-positive bacteria. The results also showed that the compounds where the benzene ring of the benzoyl moiety contained a methyl group or a chlorine or bromine atom in the para position showed higher antimicrobial activity. Similar influences were identified where either a bromine or chlorine atom was in the meta position.
