An .alpha.-tocopheryl 5-substituted picolinate of the formula ##STR1## wherein R represents an alkyl group which may have a substituent, a lower alkenyl group, a phenyl(lower alkyl) group, or a phenyl group which may have a substituent, and Q represents a methylene group or an oxygen or sulfur atom, or a pharmaceutically acceptable acid addition salt thereof. This compound can be produced by reacting a substituted picolinic acid of the formula ##STR2## wherein R and Q are as defined above, or its reactive derivative with .alpha.-tocopherol of the formula ##STR3## and as required, contacting the resulting compound with a pharmaceuticlly acceptable acid. A pharmaceutical composition comprising said compound as an active ingredient is useful for the treatment of hypertension.
一种公式为##STR1##的α-生育酚5-取代吡啶酸盐,其中R代表一种烷基,该烷基可能具有取代基,较低的烯基基团,苯基(较低的烷基)基团或苯基,该苯基可能具有取代基,Q代表亚甲基基团或氧或硫原子,或其药学上可接受的酸盐。该化合物可通过将公式为##STR2##的取代吡啶酸或其反应性衍生物与公式为##STR3##的α-生育酚反应,并根据需要,将所得化合物与药学上可接受的酸接触而制备得到。含有该化合物作为活性成分的制药组合物对于治疗高血压具有用处。
