Discovery of orally available integrin α5β1 antagonists

Previous research within our laboratories identified the 3-hydroxypyrrolidine scaffold 1 as a new and selective integrin α5β1 inhibitor class which was designed for local administration. Herein the discovery of new orally available integrin α5β1 inhibitor scaffolds for potential systemic treatment is described.

NEW HETEROCYCLIC COMPOUNDS FOR THE INHIBITION OF INTEGRINS AND USE THEREOF

The present invention is related to a compound of formula (I), wherein A is a radical selected from the group comprising aromatic heterocyclic 5-membered ring systems; Ar is a radical selected from the group comprising optionally substituted 5- and 6-membered aromatic ring systems, whereby the ring system contains 0, 1, 2 or 3 heteroatoms selected from the group comprising N, O and S; Z is a radical individually and independently selected from the group comprising (CH2)n-E-(CH2)m-L-(CH2)k and (CH2)m-L-(CH2)k, wherein E is a radical which is either absent or present, whereby if E is present, E is selected from the group comprising O, S, NH, NRa, CO, SO, SO2, acetylene and substituted ethylene; L is a radical which is either absent or present, whereby if L is present, L is individually and independently selected from the group comprising O, S, NH, NRb, CO, SO, SO2, substituted ethylene and acetylene; and k, m and n are individually and independently O, 1, 2 or 3; ψ is a radical of formula (II), wherein Q is a radical selected from the group comprising a direct bond, Cl-C4alkyl, C=O, C=S, O, S, CRaRb, NRa-NRb, N=N, CRa=N, N=CRa, (C=O)-O, 0-(C=O), SO2, NRa, (C=O)-NR3, NRa-(C=0)-NRb, NRC-(C=O), 0-(C=0)-NRc, NRc-(C=0)-0, NRC-(C=S), (C=S)-NRc, NRc-(C=S)-NRd, NRC-SO2 and SO2-NRc.
