Accumulation of cytotoxic lipofuscin bisretinoids may contribute to atrophic age-related macular degeneration (AMD) pathogenesis. Retinal bisretinoid synthesis depends on the influx of serum all-trans-retinol (1) delivered via a tertiary retinol binding protein 4 (RBP4)-transthyretin (TTR)-retinol complex. We previously identified selective RBP4 antagonists that dissociate circulating RBP4-TTR-retinol complexes, reduce serum RBP4 levels, and inhibit bisretinoid synthesis in models of enhanced retinal lipofuscinogenesis. However, the release of TTR by selective RBP4 antagonists may be associated with TTR tetramer destabilization and, potentially, TTR amyloid formation. We describe herein the identification of bispecific RBP4 antagonist-TTR tetramer kinetic stabilizers. Standout analogue (±)-44 possesses suitable potency for both targets, significantly lowers mouse plasma RBP4 levels, and prevents TTR aggregation in a gel-based assay. This new class of bispecific compounds may be especially important as a therapy for dry AMD patients who have another common age-related comorbidity, senile systemic amyloidosis, a nongenetic disease associated with wild-type TTR misfolding.

In this paper, we report the optimization of a series of novel, potential antipsychotic derivatives combining potent dopamine D2, D3 and serotonin 5-HT1A, 5-HT2A receptor affinities. The pharmacological features of compound 27 are a high affinity for dopamine D2, D3 and serotonin 5-HT1A, 5-HT2A receptors. Moreover it possesses low affinity for 5-HT2C and H1 receptors (to reduce the risk of obesity associated with chronic treatment) and hERG channels (to reduce the incidence of torsade des pointes). Furthermore, compound 27 inhibited apomorphine-induced climbing, MK-801-induced hyperactivity and DOI-induced head twitch without observable catalepsy at the highest dose tested in mice. Taken together, among the amide derivatives, we identified compound 27 as a potential antipsychotic lead candidate.
