Optimization of lead compound 2 is described, mainly focusing on modification at the C-2 position of the benzimidazole core. Replacement of the phenyl linker of 2 with saturated rings resulted in identification of compound 8b which combines high Y5 receptor binding affinity with a good ADME profile leading to in vivo efficacy.
