Biochem/physiol Actions

UCSF924 (Compound 9-6-24; ZINC000091726127) is a selective, high-affinity dopamine D4 receptor (DRD4) partial agonist (Ki = 3 nM for human D4) with a 7.4-fold bias toward arrestin recruitment over Gαi (Gαi/0; Gi/G0) signaling activation with respect to quinpirole. UCSF924 exhibits no detectable affinity for D2, D3 or the F261V/L328F D4 mutant and no agonist activity toward a panel of 320 nonolfactory GPCRs even at a high concentration of 1 μM. The UCSF924 structure analog UCSF924NC (Comound 9-6-16; ZINC000091707446) is the recommended negative control compound with a 1/2500-fold reduced D4 affinity.

Dopamine receptors are implicated in the pathogenesis and treatment of nearly every neuropsychiatric disorder. Although thousands of drugs interact with these receptors, our molecular understanding of dopaminergic drug selectivity and design remains clouded. To illuminate dopamine receptor structure, function, and

Endosomal-autophagic-lysosomal (EAL) dysfunction is an early and prominent neuropathological feature of Alzheimers's disease, yet the exact molecular mechanisms contributing to this pathology remain undefined. By combined biochemical, immunohistochemical and ultrastructural approaches, we demonstrate a link between EAL pathology and the
