A series of N-sulfonylimines andα-bromoacetamides were prepared.

Purpose To study the effect of chronic glutathione (GSH) depletion in vivo by injection of L-buthione- -sulfoximine (BSO) on the balance of intracellular and interorganic GSH and on the several enzymes activity in GSH regulation and GCSmRNA expression.

Objective: To investigate the effect of BSO on DAAO/D-Ala system killing K562e cells.

BSO up-regulating cisplatin sensitivity of a MRP-overexpression lung cell line SPC-A-1 by changing the activity of GSH detoxification system;

A Series sulfonated polyimides (SPI) for fuel cells were synthesized via direct polymerization with a sulfonated aromatic diamine (S-ODA), a non-sulfonated diamine (ODA) and 3, 3′, 4, 4′-benzophenoneteracarboxylic dianhydride(BTDA), and then characterized by FT-IR.

A series of new six-member sulfonated polyimides(SPI-X) containing benzoxazole moieties were prepared by one-step high temperature polymerization method.

To prepare polymer electrolyte membranes for direct methanol fuel cell(DMFC), a series of novel sulfonated polyimides(SPI) were synthesized from sulfonated diamine,2,5-bis(4-aminophenoxy)benzene sulfonic acid (S-TBDA) with 3,3′,4,4′- benzophenone tetracarboxylic dianhydride (BTDA) and non-sulfonated diamine(ODA) via direct polymerization in this study.

Sulfonated poly(ether imide) (SPEI) and poly(ether sulfone) (PES) blend membranes for application in the direct methanol fuel cells (DMFC) were successfully prepared by solution blend technique.
