A new series of N-hydroxyethylpyrazole (12a-f) and N-hydroxymethylpyrazole derivatives (15a-f) were designed for their estrogenic activities, having a 11.0 ± 0.5 A distance between their two hydroxyl groups, aliphatic-OH and phenolic-OH similar to 17β-estradiol (E2) as an endogenous hormone. To synthesize the title compounds, the key intermediate 1,3-dicarbonyl derivatives (2 and 8), were treated with hydrazine hydrate to produce the pyrazole ring 5 and 9. Further hydroxyalkylation of the latter produced the title pyrazoles. The position of hydroxyethyl or hydroxymethyl substituents in the products was determined through 2D NOE NMR spectroscopy.

The synthesis and study of the oral antiallergic activity of a series of monopyrazole derivatives (2-14) considered as analogues of active bispyrazole 1 are described.None of the compounds showed significant inhibition of the rat passive cutaneous anaphylaxis (PCA), with the exception of the already known 5-aminoindazole (2).The activity of this compound is, however, lower than that of compound 1.
Azasteroids compounds and derivatives
-
, (2008/06/13)
Azasteroids and certain derivatives each of a five ring system containing at least one aromatic nucleus and at least one nitrogen atom. The ring system is fused to a tetrahydrotetralin system or a tetrahydrophenanthrene system. The compounds have solubility in water and disclose antimicrobial, antifertility and potentiate the activity of antibiotics and certain anticancer agents.
