A comparison has been made of the effects of three nitrosoureas (BCNU, CCNU, and methyl-CCNU) on the cells of Lewis lung carcinoma and B16 melanoma in vivo using a new in vitro method for assaying colony-forming cells. In addition, the effect on early hemopoietic precursors has been studied using the in vivo spleen colony assay and the in vitro agar colony assay. The results show that the three nitrosoureas are selective against Lewis lung carcinoma and B16 melanoma relative to normal hemopoietic precursors. Furthermore, the effect of these nitrosoureas is unchanged when the rate of proliferation of the hemopoietic precursor cells is increased.

The antitumor and immunosuppressive activities of the lankacidin-group antibiotics were studied in mice. Seventeen of 29 newly prepared lankacidin-group antibiotics, including 14-derivatives of lankacidin C, lankacidinol, isolankacidinol, and lankacidinol 14-acetate, possessed considerable antitumor activity against ascites 6C3HED/OG lymphosarcoma. Comparative studies on the antitumor activity of lankacidin C and eight of its derivatives against L1210 leukemia and solid 6C3HED/OG lymphosarcoma demonstrated that replacement of the hydroxyl group at position 8 or 14 of lankacidin C by an acyloxy group potentiated antitumor activity. However, these modifications of lankacidin C resulted in reduction of the immunosuppressive activity.

An initial clinical phase I trial of inosine dialdehyde has been carried out in 40 patients at dose levels of 30-4000 mg/m2 for 5 days given intravenously (iv) monthly. At 1.5 g/m2, noncumulative dose-related toxicity occurred in all patients which consisted of nausea and vomiting, local pain, alterations in coagulation mechanism, elevated partial thromboplastin time, and positive Coombs' test. No dose-limiting leukopenia, thrombocytopenia, anemia, or bleeding occurred; however, depression of the leukocyte and platelet counts, and decreased hemoglobin value were observed. The dose-limiting toxic effect was renal tubular damage with reversible acute renal failure in one of four patients who received 3000 mg/m2 iv for 5 days. Refractory hypercalcemia was controlled in three of three patients without tumor effect. Responses occurred in patients with seminoma, oat cell carcinoma, and melanoma. A starting dose of 2 g/m2 for 3 days monthly is recommended for phase II trials and a trial in lung carcinoma is now being conducted.

Treatment of certain malignancies with high-dose methotrexate/citrovorum factor rescue has recently been adopted as an effective regimen. A microbiologic assay capable of detecting citrovorum factor in the presence of massive amounts of methotrexate has been developed using a strain of Pediococcus cerevisiae resistant to methotrexate. The assay described in this paper is an inexpensive and rapid method of studying the distribution kinetics of citrovorum factor.
