    • A compound represented by the formula [I]: ##STR1## wherein R.sup.3 represents a lower alkanoyl group; R.sup.4 represents a substituted or unsubstituted benzoyl group; ring A represents a substituted or unsubstituted cyclopropane ring; X represents a single bond or a group represented by --O--, --S-- or --NH--; R represents a substituted or unsubstituted lower alkyl group (wherein said lower alkyl group may have a cycloalkyl moiety), a substituted or unsubstituted aryl group or a substituted or unsubstituted aromatic heterocyclic group; E represents hydrogen atom or a group represented by --CO(CH.sub.2).sub.n ZY; Y represents a residue obtained from an amino acid or a dipeptide by removing hydroxyl group in one carboxyl group therefrom (wherein amino group existing in said residue may be protected, and carboxyl group existing in said residue may be esterified or amidated); Z represents a group represented by the formula of --O-- or --NH--; and n represents 1, 2, 3, 4, 5 or 6, or a pharmaceutically acceptable salt thereof. Said compounds have excellent antitumor activity so that they are useful in the prophylaxis or treatment of a wide range of tumors such as breast cancer, ovary cancer, lung cancer, malignant melanoma and the like.
    • 由式[I]表示的化合物:其中R 3表示低级烷酰基; R4表示取代或未取代的苯甲酰基; 环A表示取代或未取代的环丙烷环; X表示单键或由-O - , - S-或-NH-表示的基团; R表示取代或未取代的低级烷基(其中所述低级烷基可以具有环烷基部分),取代或未取代的芳基或取代或未取代的芳族杂环基; E表示氢原子或由-CO(CH 2)n ZY表示的基团; Y表示通过从其中除去一个羧基中的羟基从氨基酸或二肽获得的残基(其中存在于所述残基中的氨基可被保护,并且所述残基中存在的羧基可被酯化或酰胺化); Z表示由式-O-或-NH-表示的基团; 和n表示1,2,3,4,5或6或其药学上可接受的盐。 所述化合物具有优异的抗肿瘤活性,因此它们可用于预防或治疗广泛范围的肿瘤如乳腺癌,卵巢癌,肺癌,恶性黑素瘤等。
