Abstract:

Twelve unreported 4H-1,2,4-benzothiadiazine 1,1-dioxide derivatives were synthesized from 2-nitrobenzene sulfonyl chloride with good water-solubility in high yields. These compounds were characterized by 1H NMR, 13C NMR, MS-ESI and elemental analysis. Their inhibiting effects on HepG-2 cell were evaluated with MTT protocol. The results show that 7-(aminomethyl)-3-cyclopropyl-1,1-dioxide-4H-benzo[e][1,2,4]thiadiazine(7c) exhibits the highest inhibition rate of 79.3% among the synthesized compounds.

Key words: 4H-benzothiadiazine dioxides derivatives, synthesis, antitumor activities
