Cell experiment: | CHO cells are stably transfected with expression plasmids encoding human V1a and grown in F-12 K, containing 10% fetal bovine serum, 1% penicillin-streptomycin, 1% glutamate, and 200 μg/mL geneticin at 37 °C in a 10% CO2 incubator at 95% humidity. Cells are plated for 24 h at 50,000 cells/well in clear bottomed 96 well plates and are dye loaded for 60 min with 2 μM Fluo-4-AM in assay buffer. After cell washing, the plate is loaded on a fluorometricimaging plate reader, compound dilution series added to the cells, and agonist activity measured[1]. |

A Single Dose, Randomized, Controlled Proof-Of-Mechanism Study of a Novel Vasopressin 1a Receptor Antagonist (RG7713) in High-Functioning Adults with Autism Spectrum Disorder
The core symptoms of autism spectrum disorder (ASD) include impaired social communication, repetitive behaviors, and restricted interests. No effective pharmacotherapy for these core deficits exists. Within the domain of social communication, the vasopressin system is implicated in social cognition and social signaling deficits of ASD, and represents a potential therapeutic target. We assessed the effects of a single 20 mg intravenous dose of the arginine vasopressin receptor 1A (V1a) antagonist, RG7713, on exploratory biomarkers (eye tracking), behavioral and clinical measures of social cognition and communication (affective speech recognition (ASR), reading the mind in the eyes, olfactory identification, scripted interaction), and safety and tolerability in a multicenter, randomized, double-blind, placebo-controlled, cross-over study of 19 high-functioning adult male subjects with DSM-IV Autistic Disorder (age 18-45 years; full scale IQ >70; ABC-Irritability subscale ?13). Eye-tracking showed an increase in biological motion orienting preference with RG7713 (ES=0.8, p=0.047) and a non-significant improvement in the composite score (ES=0.2, p=0.29). RG7713 reduced ability to detect lust (ES=-0.8, p=0.03) and fear (ES=-0.7, p=0.07) in ASR. However, when all eight individual emotion subscales were combined into an overall ASR performance score, the reduction was non-significant (ES=-0.1, p=0.59). Thirteen adverse events were reported in 10 subjects; all were of mild (11/13) or moderate (2/13) severity. Although interpretation should be cautious due to multiple comparisons and small sample size, these results provide preliminary evidence from experimental and behavioral biomarkers, that blockade of the V1a receptor may improve social communication in adults with high-functioning ASD.

Discovery of highly selective brain-penetrant vasopressin 1a antagonists for the potential treatment of autism via a chemogenomic and scaffold hopping approach
From a micromolar high throughput screening hit 7, the successful complementary application of a chemogenomic approach and of a scaffold hopping exercise rapidly led to a low single digit nanomolar human vasopressin 1a (hV1a) receptor antagonist 38. Initial optimization of the mouse V1a activities delivered suitable tool compounds which demonstrated a V1a mediated central in vivo effect. This novel series was further optimized through parallel synthesis with a focus on balancing lipophilicity to achieve robust aqueous solubility while avoiding P-gp mediated efflux. These efforts led to the discovery of the highly potent and selective brain-penetrant hV1a antagonist RO5028442 (8) suitable for human clinical studies in people with autism.
