| 描述 | Penicillamine (D-(-)-Penicillamine) is the most characteristic degradation product of the penicillin antibiotics. It is used as an antirheumatic and as a chelating agent in Wilson's disease[3]. D-Penicillamine is the d isomer of a dimethylated cysteine and has been used for the treatment of rheumatoid arthritis. D-penicillamine significantly reduced L-cysteine-induced vasodilatation in a concentration-dependent manner through inhibition of H2 S biosynthesis, and this effect occurred at concentrations 10 times lower than those needed to induce the release of H2 S. In particular, D-penicillamine selectively inhibited CSE in a pyridoxal-5'-phosphate-dependent manner[4]. In animals, both intravenous D-penicillamine doses of 11 (low) and 44 mg/kg (high) decreased the mortality caused by s.c. isoprenaline (100 mg/kg) from 36% to 14% and 22%, respectively. However, whereas the low D-penicillamine dose decreased the release of cardiac troponin T (specific marker of myocardial injury), the high dose resulted in an increase[5]. In most normal human sera the addition of penicillamine to a final concentration of 0-2 mmol/l and subsequent dialysis caused a slight reduction in serum haemolytic complement (CH50). In vivo, a dose of 240 mg penicillamine caused a slight transient reduction in CH50 in rabbit serum, while 1000 mg penicillamine had no effect on serum CH50 in patients with rheumatoid arthritis[6]. | ||
