G. Vanlommen et al., THE DISCOVERY OF A SERIES OF NEW NON-INDOLE 5HT(1D) AGONISTS, Bioorganic & medicinal chemistry letters, 5(22), 1995, pp. 2649-2654
The synthesis and SAR of a series of non-indole 5HT(1D) agonists is de
scribed. The most interesting molecule of this series is compound 13,
alniditan. It is active as a constrictor of the saphenous vein of the
dog and of the pig basilar artery with ED(50) values of 9.09x10(-9)M a
nd 2.29x10(-8)M respectively, and it has high affinities to the 5HT(1D
)-receptor and to the 5HT(1D)-receptor with pK(i) values of 8.6 and 8.
3 respectively.
