11β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) has attracted considerable attention during the past few years as a potential target for the treatment of diseases associated with metabolic syndrome. In our ongoing work on 11β-HSD1 inhibitors, a series of new 2-amino-1,3-thiazol-4(5H)-ones were explored. By inserting various cycloalkylamines at the 2-position and alkyl groups or spirocycloalkyl groups at the 5-position of the thiazolone, several potent 11β-HSD1 inhibitors were identified. An X-ray cocrystal structure of human 11β-HSD1 with compound 6d (Ki = 28 nM) revealed a large lipophilic pocket accessible by substitution off the 2-position of the thiazolone. To increase potency, analogues were prepared with larger lipophilic groups at this position. One of these compounds, the 3-noradamantyl analogue 8b, was a potent inhibitor of human 11β-HSD1 (Ki = 3 nM) and also inhibited 11β-HSD1 activity in lean C57Bl/6 mice when evaluated in an ex vivo adipose and liver cortisone to cortisol conversion assay.

A new preparative procedure was developed for N-adamantylation of carboxylic acids amides and ureas, and C5-adamantylation of barbituric acid in trifluoroacetic acid medium with tertiary adamantanols and 1-adamantylalkanols. The reaction of 2-adamantanols and secondary 1-adamantylalkanols with nitriles was for the first time used in the preparation of W-(2-adamantyl)-and N-(1-adamantylalkyl)amides.
