AIM To study the effects of cyclophosphamide (CTX) on the pharmacokinetics of buthionine sulfoximine (BSO)in Walker 256 tumor bearing rats. METHODS Walker 256 tumor bearing rats were treated ip for 4 days with saline or CTX in saline (20 mg?kg -1 ), then received iv BSO 200 mg?kg -1 . BSO concentration in rat plasma was determined by a reverse phase HPLC with fluorescence detection after precolumn derivatization with o phthaldialdehyde. Compartment model and pharmacokinetic parameters were determined by 3P87 software processed on a computer. RESULTS A single intravenous dose of BSO 200 mg?kg -1 was eliminated from plasma in a two compartment manner in tumor bearing rats. The pharmacokinetic parameters of BSO were as follows: In tumor bearing control rats, T 1/2? =(11 1?2 4) min, T 1/2? =(65?14) min, CLs=(12 8?1 3) ml?min -1 ?kg -1 , AUC=(262?26) mg?L -1 ?h; in tumor bearing CTX treated rats, T 1/2? =(8 2?1 8) min, T 1/2? =(42?3) min, CLs=(13 4?1 9) ml?min -1 ?kg -1 ,AUC=(252?35) mg ?L -1 ?h. CONCLUSION There is no significant difference between the parameters of tumor bearing control and CTX treated rats except T 1/2? .

Prostaglandin F2? ( PGF2? ) in the brain cortex was measured in mice which were devided into 3 groups, ie sham operation group, cerebral ischemia group and reperfusion after cerebral ischemia group, treated with saline or clonidine ( 0 .15~1 .Omg/kg ) , respectively. The results showed that the PGF2? level in the ischemia group treated with saline was higher than sham operation group, but the PGF2? level in reperfusion group was the highest in all groups. Compared with saline, clonidine decreased the PGF2? levels either in the ischemia group or the reperfusion group significantly . This may be useful to attenuate the brain lesion caused by PGF2? .

Buthionine salfoximine (BSO) is a chemotherapeutic sensitizor under clinical trial. BSO can reverse multidrug resistance in vitro and in vivo. The author reviewed the mechanism, pharmacodynamics, pharmacokinetics and the progress in clinical research of BSO. BSO is a selective inhibitor of 7-glutamylcysteine synthetase, the rate-limiting enzyme in gluthionine synthesis. Depletion of intracellular gluthionine by BSO can reverse tumor resistance to chemotherapeutic a-gents such as platinating and alkylating agents. In tumor-bearing animals BSO enhanced the therapeutic index of chemotherapeutic agents. Animals treated with BSO had a longer life span. Pharmacokinetics of BSO was a two-compartment manner in mice, dogs and huamn beings. The efficacy of BSO in cancer patients is being investigated in clinical trial.
