N-acylated alpha-(3-pyridylmethyl)-beta-aminotetralin antagoinists of the human neuropeptide Y Y5 receptor.

Alpha-(3-Pyridylmethyl)-beta-aminotetralins were acylated with amino-piperidinyl and-pyrrolidinyl acetic acids, and with (aminomethyl)cyclohexanecarboxylic acid. Reaction with acyl chlorides, chloroformates, and isocyanates gave amides 8e, carbamates 9, and ureas 10, which bound to the Y5 receptor with nanomolar affinity. Congeners 11a and 11d containing a terminal benzimidazolone group were shown to be functional Y5 antagonists.

N-(sulfonamido)alkyl[tetrahydro-1H-benzo[e]indol-2-yl]amines: potent antagonists of human neuropeptide Y Y5 receptor.

[3a,4,5,9b-Tetrahydro-1H-benzo[e]indol-2-yl]amines were prepared via reductive amination and concomitant cyclization of alpha-cyanomethyl-beta-aminotetralins. N-acylation with omega-sulfonamido-carboxylic acids and subsequent reduction afforded a series of N-(sulfonamido)alkyl[tetrahydro-1H-benzo[e]indol-2-yl]amines, which bound to the human neuropeptide Y Y5 receptor with nanomolar affinity.

Multi-component methodologies in solid-phase organic synthesis.

Solid-phase organic synthesis, particularly when used in conjunction with combinatorial techniques, is emerging as a revolutionary technology in chemistry. Multi-component reaction systems are particularly valued because several elements of diversity can be introduced in a single transformation thereby expanding the diversity of compound libraries. A variety of multi-component reactions have been successfully adapted for solid-phase technology as described in this review.
