One of 6 newly synthesized triazinium zwitterions (JR-1--JR-6) was shown to induce 51Cr-release from leukemic (HL60 and CEM) and solid tumor (MM170 and HeLa) cell-lines. Leukemic cells were more sensitive to this compound than solid tumors as demonstrated by dose-response and time-course studies. Other experiments showed that JR-6 (1-methyl-3-phenyl-1,2,4-triazinium-5-olate) significantly suppressed protein, RNA and DNA synthesis at tumoricidal concentrations.
