Automated platforms allow for rapid, detailed screening of chemical systems.

Here, we report the synthesis of 3,6,9-trioxaundecan-1-{4-[(2-Chloroethyl)Ethylamino)]-Benzylamino},11-Azide (CEBA). CEBA alkylates N7 guanine DNA thanks its chloroethyl group and can be coupled by a strain-promoted azide-alkyne cycloaddition to an alkynylated molecule. The optimization alkylation level pDNA reveals that expression encoded gene is preserved when it randomly modified with at mos...

The alkylation of phosphates in DNA by therapeutically active haloethylnitrosoureas was studied by reacting N-chloroethyl-N-nitrosourea (CNU) with dTpdT, separating the products by HPLC, and identifying them by co-chromatography with authentic markers. Both hydroxyethyl and chloroethyl phosphotriesters of dTpdT were identified; a similar reaction between CNU and dTR yielded 3-hydroxyethyl and 3...

Bis-(2-chloroethyl) sulfide (sulfur mustard, SM) is a carcinogenic alkylating agent that has been utilized as a chemical warfare agent. To understand the mechanism of SM-induced lung injury, we analyzed global changes in gene expression in a rat lung SM exposure model. Rats were injected in the femoral vein with liquid SM, which circulates directly to the pulmonary vein and then to the lung. Ra...

The hydroboration of phenyl vinyl sulfide with catecholborane (HBcat) and pinacolborane (HBpin) has been examined with a number of rhodium complexes, all of which proceed with excellent regiocontrol in favour of the branched product PhSCH(B(OR)2)CH3. The corresponding linear product can be obtained exclusively in reactions employing [Cp*IrCl2]2 and HBcat. Catalysed hydroborations of (E)-2-(p-to...

n,n-dichloropolystyrene sulfonamide as a decontaminant was synthesized in 5 steps from styrene monomer. styrene was first polymerized. then, sulfonation reaction was performed by h2so4 (c) followed by chlorination with pocl3 obtain chlorosulfonated polystyrene. amidification reaction was then applied to get sulfonamide resin. sulfonamide resin was treated with sodium hypochloride to obtain n,n-...

Sulfur mustard (SM), a chemical warfare agent, is strong alkylating compound that readily reacts with numerous biomolecules. The goal of the present work was to define and validate new biomarkers exposure SM could be easily accessible in urine or plasma. Because investigations using are prohibited by Organization for Prohibition Chemical Weapons, we worked 2-chloroethyl ethyl sulfide (CEES), mo...
