Synthesis of novel 2-(1-adamantanylcarboxamido)thiophene derivatives. Selective cannabinoid type 2 (CB2) receptor agonists as potential agents for the treatment of skin inflammatory disease
A set of CB2R ligands, based on the thiophene scaffold, was synthesized and evaluated in in vitro assays. Compounds 8c-i, k, l, bearing the 3-carboxylate and 2-(adamantan-1-yl)carboxamido groups together with apolar alkyl/aryl substituents at 5-position or at 4- and 5-positions of the thiophene ring possess high CB2R affinity at low nanomolar concentration, good receptor selectivity, and agonistic
bioactivity and selectivity for CB2R in calcium mobilization assays, and four displayed CB2R agonist activity, with EC50 values below 30 nm. The compound exhibiting the highest agonist activity toward CB2R (EC50=7.53±3.15 nm) had a selectivity over CB1R of more than 1328‐fold. Moreover, structure–activity relationship (SAR) studies indicated that the substituents on the nucleus play key roles in the functionality
The invention relates to the inhibition of histone deacetylase. The invention provides compounds and methods for inhibiting histone deacetylase enzymatic activity. The invention also provides compositions and methods for treating cell proliferative diseases and conditions.
