The role of glutathione (GSH) in the effectiveness of and resistance to 7 platinum compounds [5 Pt(II) and 2 Pt(IV) drugs] was evaluated in a 8.6-fold cisplatin (CDDP)-resistant human small cell lung cancer cell line (GLC4/CDDP), the parent GLC4 line, a 3.7-fold CDDP-resistant human embryonal carcinoma cell line (Tera-CP), and the parent Tera line (NTera2/D1). Resistance factors for both CDDP-resistant cell lines were determined after continuous incubation (4 days) with CDDP. Continuous incubation with the other studied platinum drugs revealed complete cross-resistance for carboplatin (CBDCA) and zeniplatin but less for enloplatin (ENLO) and iproplatin in both models. Tetraplatin and lobaplatin showed, respectively, partial and complete cross-resistance in GLC4/CDDP but no cross-resistance in Tera-CP. GSH level, but not glutathione S-transferase activity, of the 4 cell lines correlated with platinum drug concentrations inhibiting cell survival by 50% after continuous incubation (r = 0.86, P |
