Compounds of the formula ##STR1## including the resolved enantiomers and/or diastereomers and mixtures thereof wherein each of one or two R is independently ##STR2## wherein n is 1-16 and R' is H or alkyl(1-4C); and wherein each remaining R is independently H, alkyl(1-6C), alkenyl(1-6C) or benzyl; an wherein said alkyl or alkenyl may be substituted by a hydroxyl, halo, or dimethylamino group, and/or interrupted by an oxygen atom, are useful in modulating the effects of internal and external stimuli on cells by reversing the effects of these stimuli on the short-term secondary messenger pathways. In particular, the compounds lower elevated levels of unsaturated, non-arachidonate phosphatidic acid (PA) and diacylglycerol (DAG) derived from said PA within seconds of the primary stimulus and their contact with said cells. The modulatory effect depends on the nature of the target cell and the stimulus applied.
式为##STR1##的化合物包括已分离的对映体和/或非对映体和它们的混合物,其中一个或两个R各自独立地为##STR2##其中n为1-16,R'为H或烷基(1-4C);其余的每个R各自独立地为H,烷基(1-6C),烯基(1-6C)或苄基;其中所述的烷基或烯基可以被羟基,卤素或二甲氨基基团取代,并/或被氧原子中断;这些化合物在调节细胞对内部和外部刺激的影响方面是有用的,通过逆转这些刺激对细胞短期次级信使途径的影响。特别地,这些化合物在主要刺激和它们与这些细胞的接触后几秒钟内降低了来源于所述PA的不饱和非花生酸磷脂酸(PA)和二酰甘油(DAG)的升高水平。调节效应取决于目标细胞的性质和应用的刺激。
