Usage

General Description

2,5-Dimethylbenzenesulfonyl chloride is a chemical compound with the molecular formula C8H9ClO2S. It is a sulfonating agent commonly used in organic and pharmaceutical synthesis. 2,5-DIMETHYLBENZENESULFONYL CHLORIDE is a derivative of benzene, with two methyl groups and a sulfonyl chloride functional group attached to the ring. It is a colorless to pale yellow liquid with a strong, pungent odor. 2,5-Dimethylbenzenesulfonyl chloride is used as a reagent in the production of pharmaceuticals, dyes, and polymers, and it is also used as an intermediate in the synthesis of other organic compounds. It is important to handle this chemical with caution, as it is corrosive and can cause severe skin and eye irritation upon contact.

Synthesis, biological evaluation, and enzyme assay of some 5-N-substituted-2-N-(arylsulphonyl)-L(+)glutamines as potential anticancer agents

Thirty 5-N-substituted-2-N-(arylsulphonyl)-L(+)glutamines were synthesized and evaluated biologically for their anticancer activities. The best active compound of this series showed 92.92% inhibition of tumor weight against Ehrlich Ascites Carcinoma cells. The most active compound was proved to be a competitive inhibitor of glutaminase in the enzyme assay. The best active compound may be a starting point to generate 'lead' for further exploration.
