The present invention provides antineoplastic .alpha.-methylene-.gamma.-butyrolactones represented by the general formula \x9bI! wherein R.sub.1 is a phenyl group optionally substituted with one or two groups selected from the group consisting of halide, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkoxy, phenyl, nitro and amino;.sub.2 R represents hydrogen, halide, (C.sub.1 -C.sub.4)alkyl or benzyl; X represents N; or wherein R.sub.1 is a phenyl group optionally substituted with one or two groups selected from the group consisting of halide, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4) alkoxy, nitro and amino; R.sub.2 represents Cl, F, or benzyl; X represents CH. These .alpha.-methylene-.gamma.-butyrolactones may be administered with an inert diluent or with a pharmaceutically acceptable carrier in controlling the growth of a neoplasm in a patient afflicted with a neoplasm disease. ##STR1##
本发明提供了一种抗肿瘤的α-亚甲基-γ-丁内酯,其通式表示为\x9bI!其中R.sub.1是一个苯基,可选地取代为卤素、(C.sub.1 -C.sub.4)烷基、(C.sub.1 -C.sub.4)烷氧基、苯基、硝基和氨基中的一种或两种基团;R代表氢、卤素、(C.sub.1 -C.sub.4)烷基或苄基;X代表N;或其中R.sub.1是一个苯基,可选地取代为卤素、(C.sub.1 -C.sub.4)烷基、(C.sub.1 -C.sub.4)烷氧基、硝基和氨基中的一种或两种基团;R.sub.2代表Cl、F或苄基;X代表CH。这些α-亚甲基-γ-丁内酯可以与惰性稀释剂或药用可接受的载体一起使用,以控制患有肿瘤疾病的患者体内肿瘤的生长。
