-
Paragraph 0075; 0076, (2017/09/19)
PROBLEM TO BE SOLVED: To provide a hydrogen acceptor capable of storing and releasing hydrogen, and a hydrogen donor conjugate therewith. SOLUTION: The invention provides pyrroloindole derivatives represented by general formula (1) (where R1 represents a C1-4 alkyl group, and R2 represents a hydrogen atom or C1-4 alkyl group; and a double line of a broken line and a solid line represents a single bond or double bond). Also provided are methods of producing them. SELECTED DRAWING: None COPYRIGHT: (C)2017,JPOandINPIT

The synthesis and biological activity are reported for a series of analogues of the previously published indole urea 2 (SB-206553), designed to probe the 5-HT(2C) receptor binding site. Small molecule modeling studies have been used to define a region in space which is allowed at the 5-HT(2C) receptor but disallowed at the 5-HT(2A) receptor. In a complementary approach, docking of 2 into our model of the 5-HT(2C) receptor has allowed us to propose a novel primary binding interaction for this series of diaryl ureas, involving a potential double hydrogen-bonding interaction between the urea carbonyl oxygen of the ligand and two serine residues in the receptor. The difference of two valine residues in the 5-HT(2C) receptor for leucine residues in the 5-HT(2A) receptor is believed to account for the observed 5- HT(2C)/5-HT(2A) selectivity with 2.
