ABSTRACT
3Beta,11beta-dihydroxy-9alpha-fluor-5alpha-androstane-17-one (2), 3beta-acetoxy-9alpha-fluor-11beta-hydroxy-5alpha-androstane-17-one (3), 3beta-acetoxy-9alpha-fluor-11beta,17beta-dihydroxy-5alpha-androstane (4), 3beta,17beta-diacetoxy-9alpha-fluor-11beta-hydroxy-5alpha-androstane (5), 3beta-acetoxy-9alpha-fluor-11beta-hydroxy-5alpha-androstane 17beta-propionate (6), 3beta-acetoxy-9alpha-fluor-11beta-hydroxy-5alpha-androstane 17beta-enanthate (7), 3beta-acetoxy-9alpha-fluor-11beta-hydroxy-5alpha-androstane 17beta-isobutyrate (8) were synthesized in the present study. Compounds 2 and 8 exhibited higher anabolic activity than the rest of the synthesized compounds. The structure of all these newly synthesized compounds was confirmed by analytic spectral data (mass, (1)H NMR and (13)C NMR).

The effects of policosanol (50-500 mg/kg) administered orally for 24 months to Sprague Dawley rats of both sexes were investigated. No differences related to daily clinical observations, weight gain, food consumption, or mortality (survival analysis) between groups were found. Histopathological study showed that the frequency of the occurrence of non-neoplastic and neoplastic (benign and malignant) lesions was similar in the control and policosanol-treated groups. The lesions observed in this study were similar to the spontaneous lesions reported in this species in previous studies. Since no drug-related increase in the occurrence of malignant or benign neoplasms was found, nor acceleration in tumors growth in any specific group was observed, this study shows no evidence of policosanol induced carcinogenicity in this strain of rats.
