The title compds. [I; R1-R3 = H, OR4; R4 = H, (HO)2P(O), alkenoyl, carboxyalkanoyl, (dialkylamino)ethyl, haloacyl, (un)substituted H2NCO; R5 = alkyl] were prepd. as neoplasm inhibitors. PhCH2COCl and PhOMe were refluxed in C2H4Cl2 contg. AlCl3 to give 4-MeOC6H4COCH2Ph. This was refluxed with NaOEt and EtI to give 4-MeOC6H4COCHEtPh. The latter underwent Grignard phenylation with 4-MeOC6H4Br in Et2O and the product was demethylated with BBr3 and then carbamoylated to give I (R1 = R2 = 4-H2NCO2, R3 = H, R5 = Et) (II). In mice 1.2 mg I/kg s.c. 99% inhibition of growth of MXT-M3.2 mammary tumors . Capsules each contg. 10 mg II were prepd. from II 10, CaHPO4 106.7, gelatin 2.3, polyoxyethylene sorbitan monooleate 1.0, and cornstarch 20 g.
