    • Use of proanthocyanidins as an active ingredient of a stimulator as a source of arginine and a source of nitric oxide in the treatment of erectile dysfunction. The active ingredient stimulates the endothelial NO-synthase enzyme, which acts as a catalyst for the synthesis of nitric oxide from its substrate L-arginine or its salts. The nitric oxide in turn activates theguanylyl cyclase, which leads to an increased development of cyclic guanosine monophosphate, which causes relaxation of smooth muscles. Blood vessel diameter may increase. The stimulator may also have Sildenafil or enzymes that inhibit an enzyme phosphodiesterase type5 from reducing an amount of the cyclic guanosine monophosphate. The substrate may be amino acid L-arginine, arginine salts or a dipeptide of arginine and aspartic acid.
    • 使用原花青素作为刺激剂的活性成分,作为精氨酸的来源和一氧化氮来治疗勃起功能障碍。 活性成分刺激内皮NO合成酶,其作为从其底物L-精氨酸或其盐合成一氧化氮的催化剂。 一氧化氮依次激活胍基环化酶,导致环鸟苷酸单磷酸酯的增加,导致平滑肌松弛。 血管直径可能增加。 刺激剂还可以具有抑制酶5磷酸二酯酶的西地那非或酶,从而减少环鸟苷酸一磷酸的量。 底物可以是氨基酸L-精氨酸,精氨酸盐或精氨酸和天冬氨酸的二肽。
