Compounds of the formula ##STR1## in which one of the symbols R.sub.1 and R.sub.2 represents an alkyl radical that has 3 or 4 carbon atoms and is unsaturated in the 2,3-position, and the other represents such a radical or lower alkyl, R.sub.3 and R.sub.4 each represents, independently of the other, hydrogen or methyl, and A represents a radical of the formula ##STR2## in which Z.sub.1, or each of Z.sub.2 and Z.sub.3 independently of the other, represents hydrogen or lower alkyl, or Z.sub.2 and Z.sub.3 together represent lower alkylene, and salts of such compounds in which Z.sub.1, or Z.sub.3 and optionally also Z.sub.2, represent(s) hydrogen, exhibit tumor-inhibiting activities.
式为##STR1##的化合物中,其中一个符号R.sub.1和R.sub.2代表具有3或4个碳原子且在2,3位置不饱和的烷基基团,另一个代表这样的基团或较低的烷基,R.sub.3和R.sub.4各自独立地代表氢或甲基,A代表式为##STR2##的基团,其中Z.sub.1,或Z.sub.2和Z.sub.3中的每一个独立地代表氢或较低的烷基,或Z.sub.2和Z.sub.3一起代表较低的烷基烯基,以及这种化合物的盐,其中Z.sub.1,或Z.sub.3和可选的Z.sub.2,代表氢时,具有抑制肿瘤的活性。
