methoxyl/sarcoma

Four new derivatives of daunorubicin, characterized by the absence of the methoxyl group at the C-4 position, have been obtained by chemical synthesis. 4-Demethoxydaunorubicin (NSC-256439) was effective against L1210 and Gross leukemias and ascites and solid Sarcoma 180 at doses four to eight times

A novel nitrosourea derivative, methyl-6-[[[(2-chloroethyl)nitrosoamino]carbonyl]-amino]-6-deoxy-alpha-D-glucopyranoside (MCNU), is a water-soluble compound in which a methoxyl group is attached to the C-1 position and an N-(2-chloroethyl)-N-nitrosoureido group is attached to the C-6 position of the

Two new analogs of adriamycin have been obtained by chemical synthesis, 4-demethoxyadriamycin and 4-demethoxy-4' -epiadriamycin. Both compounds were highly effective against experimental mouse tumors at doses about ten times lower than those effective for adriamycin. At the optimal dose,
