Chain mediating effect of insomnia, depression, and anxiety on the relationship between nightmares and cognitive deficits in adolescents.

Background: The study explored the differences in nightmare, insomnia, depression, anxiety, and cognitive deficits among adolescents and the chain mediating effects of insomnia, depression, and anxiety on the relationship between nightmares and cognitive deficits in adolescents.

Methods: An online survey was used to collect demographic data of 6014 adolescents and assess nightmare, insomnia, depression, anxiety, and cognitive deficits using the Chinese Version of Nightmare Distress Questionnaire, Insomnia Severity Index, Patient Health Questionnaire 9, Generalized Anxiety Disorder 7, and Perceived Deficits Questionnaire-Depression. Spearman correlation analysis and the SPSS function "PROCESS macro" were used for correlation and mediation analyses, respectively.

Association between GPx-1 polymorphisms and personality traits in healthy Chinese-Han subjects.

Objectives: Cloninger developed the three-dimensional personality theory and Tridimensional Personality Questionnaire (TPQ), which shows that some dimensions of personality traits are heritable and related to neurotransmitters including dopamine. glutathione peroxidase 1 (GPx1) plays an important role in metabolic dopamine change and closely relates to neurological and psychiatric disorders. The impact of GPx-1 polymorphisms has been rarely explored in the field of personality traits.

Synthesis and pharmacological evaluation of trifluoromethyl containing 4-(2-pyrimidinylamino)benzamides as Hedgehog signaling pathway inhibitors.

In present study, a series of novel containing trifluoromethyl 4-(2-pyrimidinylamino)benzamide derivatives were designed by the fluorine scan strategy. Their Hh signaling inhibitory activities were evaluated by Gli-luciferase reporter method. The comprehensive SAR was discussed and several derivatives were found to display more potent Hh signaling inhibitory activity than positive drug vismodegib.

Discovery of novel 4-(2-pyrimidinylamino)benzamide derivatives as highly potent and orally available hedgehog signaling pathway inhibitors.

A series of novel hedgehog signaling pathway inhibitors have been designed by structural modification based on the former reported scaffold of 4-(2-pyrimidinylamino)benzamide. The SAR for this series was described and many derivatives showed potent inhibitory activity. Among these compounds, compounds 12af and 12bf were identified to have high potency and optimal PK profiles.

Design, synthesis, and evaluation of pyrrolo[2,1-f][1,2,4]triazine derivatives as novel hedgehog signaling pathway inhibitors.

A novel series of Hh signaling pathway inhibitors were designed by replacing the pyrimidine skeleton of our earlier reported lead compound 1 with pyrrolo[2,1-f][1,2,4]triazine scaffold. Starting from this new scaffold, SAR exploration was investigated based on structural modification on A-ring, C-ring and D-ring. And several much potent compounds were studies in vivo to profile their pharmacokinetic properties.
