Chain-branched 1,3-dibenzylthioureas as vanilloid receptor 1 antagonists

A series of chain-branched 1,3-dibenzylthiourea derivatives were synthesized, and tested their antagonist activity against vanilloid receptor 1. Chain-branching led to a significant change in the mode of action and the potency. ( R)-Methyl or ethyl-branched 1,3-dibenzylthiourea derivatives showed th...

Description
Summary:A series of chain-branched 1,3-dibenzylthiourea derivatives were synthesized, and tested their antagonist activity against vanilloid receptor 1. Chain-branching led to a significant change in the mode of action and the potency. ( R)-Methyl or ethyl-branched 1,3-dibenzylthiourea derivatives showed the most potent antagonist activity up to the IC 50 value of 0.05 μM which is 10-fold more potent than capsazepine. Chain-branching led to a significant change in the mode of action and the potency against vanilloid receptor 1.
