Protective Effects of 2-Amino-5,6-dihydro-4H-1,3-thiazine and Its Derivative against Radiation-Induced Hematopoietic and Intestinal Injury in Mice

Ionizing radiation (IR) acts as an external stimulating factor, when it acts on the body, it will activate NF-kappa B and cause the up-regulation of inducible nitric oxide synthase (iNOS) and induce a large amount of nitric oxide (NO) production. NO and other reactive nitrogen and oxygen species (RNS and ROS) can cause damage to biological molecules and affect their physiological functions. Our study investigated the protective role of 2-amino-5,6-dihydro-4H-1,3-thiazine hydrobromide (2-ADT) and 2-acetylamino-5,6-dihydro-4H-1,3-thiazine hydrobromide (2-AADT), two nitric oxide synthase inhibitors, against radiation-induced hematopoietic and intestinal injury in mice. Pretreatment with 2-ADT and 2-AADT improved the survival of mice exposed to a lethal dose of radiation, especially, the survival rate of the 2-ADT 20 mg/kg group was significantly higher than that of the vehicle group (p < 0.001). Our findings indicated that the radioprotective actions of 2-ADT and 2-AADT are achieved via accelerating hematopoietic system recovery, decreasing oxidative and nitrosative stress by enhancing the antioxidant defense system and reducing NO as well as peroxynitrite (ONOO-) content, and mitigating the radiation-induced DNA damage evaluated by comet assay. These results suggest that 2-ADT and 2-AADT may have great application potential in ameliorating the damages of radiotherapy. Synthetic Route of 2235-54-3, The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 2235-54-3.

N-Radical-Initiated Cyclization through Insertion of Sulfur Dioxide under Photoinduced Catalyst-Free Conditions

A N-radical-initiated cyclization involving the sulfonylation of unactivated alkenes through insertion of sulfur dioxide in the presence of visible light under catalyst-free conditions is accomplished. A range of sulfonated 3,4-dihydro-2H-pyrroles can be generated in good yields under photoinduced sulfonylative conditions. Additionally, the corresponding 2-(3,4-dihydro-2H-pyrrol-2-yl)methylsulfonyl-1-arylethanones can be easily converted to 3,4-dihydro-2H-1,4-thiazine 1,1-dioxides. This photoinduced transformation occurs efficiently at room temperature under catalyst-free conditions, and various functional groups can be tolerated. A tandem radical process is involved through the iminyl radical-mediated cyclization with the insertion of sulfur dioxide; this process shows high efficiency and good selectivity.

Synthesis of the Fused Tetracyclic Thiazinan-4-one Derivatives and Their Anti-tumor Activitiy

The benzothiazin-4-one intermediates were prepared by the one-pot three-components condensation from the N-Boc-L-prolinal 1, amino acid ethyl/methyl ester hydrochlorides 2a similar to 2d, and mercaptobenzoic acids 3a similar to 3b. After removal of Boc, the target novel fused tetracyclic thiazinan-4-one derivatives 6 similar to 11 were afforded by the intramolecular cyclo- amidation reaction. The absolute configurations of the newly generated chiral carbon (1-C) were determined by the coupling constants of H-1 and H-2 and the X-ray crystallographic structures. The tetracyclic alkaloids were examined for their anti-proliferative activity against Hela and A549 tumor cells. The results showed that some compounds could moderately inhibit the growth of Hela cells, and among them, (13aR, 13bR)-1,2,3,13b-tetrahydrobenzo[e]pyrrolo[2′, 1′: 3,4] pyrazino[2,1b][1,3] thiazine-5,8(6H, 13aH)-dione (6b) was the best one with the IC50 value of 9.50 mu mol/L. However, all the compounds showed no anti-tumor activity against A549.
