- Five-membered heterocyclic compounds as inhibitors of SRC family protein kinase.
-
The present invention refers to novel substituted aromatic heteroaryl derivatives of formula (I). with the definitions of A, L1, L2, G, J, X and Y according to claim 1. These novel compounds are useful for the inhibition of protein kinases, particularly of the inhibition of Src family protein kinases. Methods for inhibiting kinases by contacting kinases with these novel compounds are disclosed. In another embodiment the present invention refers to pharmaceutical compositions containing these novel compounds and their use for the preparation of medicaments for treating diseases or disorders associated with unphysiological activity of kinases in the body, particularly for the treatment of cancer, immunosuppression, and osteoporosis.

- Substituted 5,5′-diphenyl-2-thioxoimidazolidin-4-one as CB 1 cannabinoid receptor ligands: Synthesis and pharmacological evaluation
-
A set of 30 substituted 5,5′-diphenyl-2-thioxoimidazolidin-4-one (thiohydantoins) derivatives was synthesized, and their affinity for the human CB1 cannabinoid receptor has been evaluated. These compounds are derived from the previously described cannabinoid ligands 5,5′- diphenylimidazolidine-2,4-dione (hydantoins). The replacement of the oxygen by a sulfur leads to an increase of the affinity while the function-i.e., inverse agonism-determined by [35S]-GTPγS experiments remains unaffected. Finally, to evaluate the molecular parameters that could influence the affinity of the thiohydantoins, molecular electrostatic potential as well as lipophilicity calculations were undertaken on representative thiohydantoins and hydantoins derivatives. In conclusion, 5,5′-bis-(4-iodophenyl)-3-butyl-2- thioxoimidazolidin-4-one (31) and 3-allyl-5,5′-bis(4-bromophenyl)-2- thioxoimidazolidin-4-one (32) possess the highest affinity for the CB 1 cannabinoid receptor described to date for the hydantoin and thiohydantoins series when compared in a same bioassay.
