The in vitro myelotoxic potentials of three investigational antitumor agents, Fostriecin, Hepsulfam and pyrazine diazohydroxide (PZDH), were evaluated utilizing clonogenic assays. Human and murine marrow cells were exposed to each drug for 1 hr prior to culture in microcapillary (human) or Petri dish (murine) assays. Fostriecin (0.22-220 microM), Hepsulfam (0.34-340 microM) and PZDH (0.68-680 microM) inhibited myeloid (CFU-gm), erythroid (BFU-e, CFU-e) and megakaryocytic (CFU-meg) colony formation in a concentration-dependent manner. CFU-e from both species were more sensitive to Fostriecin than the other progenitors and murine cells more sensitive overall to Fostriecin than their human counterparts. Murine CFU-e were also more sensitive to Hepsulfam than human CFU-e, with CFU-gm and BFU-e being similarly affected in both species. Human BFU-e were greatly inhibited by PZDH, whereas murine BFU-e were relatively resistant to its toxic effects. Fostriecin was the most toxic of the three antitumor agents, with PZDH the least toxic.

D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
