Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Farmaco, Edizione Scientifica called Pharmacology of p-hydroxypropiophenone sulfate, Author is Setnikar, I.; Murmann, W., which mentions a compound: 129-18-0, SMILESS is O=C(N(C1=CC=CC=C1)N2C3=CC=CC=C3)[C-](CCCC)C2=O.[Na+], Molecular C19H19N2NaO2, Quality Control of Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide.
The Na salt has low toxicity in acute and chronic application. It is well tolerated when injected locally in not too concentrated solutions It does not inhibit the pituitary secretion of adrenocorticotropin in the normal animal or in stress of variable severity. It neither inhibits the secretion of somatotropic hormone nor has any influence on the normal growth. It does, however, inhibit the secretion of gonadotropin by the pituitary if this secretion is abnormally high. It also inhibits thyrotropic hyperfunction of the hypophysis if a hyperfunction exists. The antigonadotropic and antithyrotropic action does not occur peripherally, but it has a central point of attack either on the hypophysis or on the centers that govern this gland. The effect on the pituitary is not caused by an estrogenic effect.
In addition to the literature in the link below, there is a lot of literature about this compound(Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide)Quality Control of Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide, illustrating the importance and wide applicability of this compound(129-18-0).
