Efficacy of peptide bound m-L-sarcolysin (peptichemio) on melphalan resistant human myeloma cells in vitro.
Peptichemio (PTC) is a mixture of six synthetic oligopeptides, each containing the alkylating agent m-di(2-chloroethyl)amino-phenylalanine. Freshly obtained myeloma cell infiltrated human bone marrow specimens were in parallel exposed to melphalan and PTC. The cytotoxic effect of the drugs on the myeloma cells of each specimen was measured by the differential staining culture method (DISC). PTC displayed higher cytotoxicity to the myeloma cells as compared to melphalan in all 12 cases analysed. The increase of the cytotoxic effect of PTC compared to melphalan varied between different cases. In melphalan resistant cases the cytotoxic effect of PTC as compared to melphalan was clearly significant (P = 0.001).
