  Spiro[tetralin-2,2'-pyrrolidine] (13) and spiro[6-methoxytetralin-2,2'-pyrrolidine] (17) were prepared by initial Michael condensation of 2-nitrotetralin and 6-methoxy-2-nitrotetralin, respectively, with methyl acrylate to give 7 and 8, both of which could be reductively cyclized to 10 and 11, followed by LiAlH4 reduction. Spiro[indan-2,2'-pyrrolidine] (15) was prepared in an analogous manner form

  Novel 2-aminotetralin derivatives were synthesized as antifungal agents. The 2-aminotetralin scaffold was chemically designed to mimic the tetrahydroisoquinoli ne ring of the lead molecule described before. Their antifungal activities were evaluated in vitro by measuring the minimal inhibitory concentrations (MICs). Compounds 10a, 12a, 12c, 13b, and 13d are more potent than fluconazole against seven testing human fungal pathogens. Compound 10b exhibits much higher antifungal activities against all of the four fluconazole-resistant clinic Candida albicans strains than the control drugs including amphotericin B, terbinafine, ketoconazole, and itraconazole. The mode of action of some compounds to the potential receptor lanosterol 14 alpha-demethylase (CYP51) was investigated by molecular docking. The studies presented here provide a new structural type for the development of novel antifungal compounds. Furthermore, 10b was evaluated in vivo by a rat vaginal candidiasis model, and it was found that 10b significantly decreases the number of fungal colony counts.
• Synthesis and cycloxygenase inhibitory properties of new naphthalene-methylsulfonamido, naphthalene-methylsulfonyl and tetrahydronaphthalen-methylsulfonamido compounds

  We synthesized a series of new naphthalene derivatives: naproxen- and 6-methoxy naphthalene acetic acid-like 1-5. In these compounds the carboxylic function, typical of the classical NSAIDs, was replaced by a methylsulfonamido (1, 2 and 6a-c) or methylsulfonyl (3-5) group present in some selective COX-2 inhibitors. We also synthesized compounds 7 and 8 in which the naphthalene portion was substituted by tetrahydronaphthalene ring. Some of the new compounds were assayed for their enzymatic inhibitory activity towards cycloxygenase enzymes. Compounds 4 and 6b, at a concentration of 10 mu M exhibit percentage inhibition values of 65%, 50% and 29%, 87% towards COX-2 and COX-1, respectively. The substitution of carboxylic group with a mehylsulfonamido or a methylsulfonyl groups does not allow to direct the selectivity versus to cycloxygenase enzymes.
