The synthesis and pharmacological evaluation of C1‐substituted adamantane hydrazones, their C2‐substituted isomers, and C1‐substituted adamantane furanoic carboxamides is described. These new adamantane derivatives exhibited an interesting pharmacological profile in terms of trypanocidal activity and selectivity. The most active adduct with the best selectivity in this study was found to be the phenylacetoxy

Compounds having Formula (I), including pharmaceutically acceptable salts and prodrugs thereof: are selective inhibitors of the 11β-HSD1 enzyme. They inhibit the 11β-HSD1-mediated conversion of cortisone and other 11-keto-glucocorticoids to cortisol and other 11β-hydroxy-glucocorticoids. The 11β-HSD1 inhibitors therefore decrease the amount of cortisol in target tissues, thereby modulating the effects of cortisol. Modulation of cortisol may be effective in controlling non-insulin-dependent diabetes (NIDDM), hyperglycemia, obesity, insulin resistance, dyslipidemia, hyperlipidemia, hypertension, Syndrome X, and other symptoms associated with NIDDM or with excess cortisol in the body.

The invention provides novel 2-adamantyl hydrazine derivatives of the general formula A
In this formula R, is hydrogen or a lower alkyl group of 1-4 carbon atoms; R2 and R3 are the same or different and are each hydrogen, an unsubstituted or substituted radical being a lower alkyl of 1-4 carbon atoms, a lower alkanoic acid radical of 2-4 carbon atoms or a lower alkyl ester thereof, adamantyl, aryl, aralkyl, in which the alkyl moiety has from 1-4 carbon atoms or an unsubstituted or substituted heterocyclic radical of aromatic character; or R2 and R3 together with the nitrogen atom to which they are attached form an unsubstituted or substituted non-aromatic cyclic radical.
The invention further provides pharmaceutically acceptable acid addition salts of the above compounds.
Several methods of preparation of the new compounds are described.
The novel compounds according to the invention possess valuable antifungal (human and plant), antiviral, antiprotozoal and antimicrobial properties.

Adamantyl triazoles were identified as selective inhibitors of 11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1). They are active both in in vitro and in in vivo pharmacodynamic models. The synthesis and structure-activity relationships of these inhibitors are presented. (c) 2005 Elsevier Ltd. All rights reserved.

A combined application of statistical molecular design (SMD), quantitative structure-activity relationship (QSAR) modeling and prediction of new active compounds was effectively used to develop salicylidene acylhydrazides as inhibitors of type III secretion (T3S) in the Gram-negative pathogen Yersinia pseudotuberculosis. SMD and subsequent synthesis furnished 50 salicylidene acylhydrazides in high purity. Based on data from biological evaluation in T3S linked assays 18 compounds were classified as active and 25 compounds showed a dose-dependent inhibition. The 25 compounds were used to compute two multivariate QSAR models and two multivariate discriminant analysis models were computed from both active and inactive compounds. Three of the models were used to predict 4416 virtual compounds in consensus and eight new compounds were selected as an external test set. Synthesis and biological evaluation of the test set in Y. pseudotuberculosis and the intracellular pathogen Chlamydia trachomatis validated the models. Y. pseudotuberculosis and C. trachomatis cell-based infection models showed that compounds identified in this study are selective and non-toxic inhibitors of T3S dependent virulence.
