The synthesis and vascular 5-HT(1B)-like receptor activity of a novel series of substituted 2, N-benzylcarboxamido-5-(2-ethyl-1-dioxoimidazolidinyl)-N, N-dimethyltryptamine derivatives are described. Modifications to the 5-ethylene-linked heterocycle and to substituents on the 2-benzylamide side chain have been explored. Several compounds were identified which exhibited affinity at the vascular 5-HT(1B)-like

To provide thienopyrazole derivatives inhibiting PDE 7 selectively, and therefore, enhance cellular cAMP level. Consequently, the compound is useful for treating various kinds of disease such as allergic diseases, inflammatory diseases or immunologic diseases. The compound is thienopyrazole compound represented by the following formula (I):

silent, competitive, and selective antagonist which shows affinity at the vascular 5HT1B-like receptors only. Changes to the size of the 2-ester substituent have a significant effect on affinity at the 5HT1B-like receptor and other receptors. Prudent placement of the carbonyl substituent in the heterocycle of the 5-side chain is crucial for good affinity and selectivity over the 5HT2A and other receptors
