Article Abstract
Parathyroid hormone 1 receptor (PTH1R) plays a key role in mediating calcium homeostasis and bone development, and aberrant PTH1R activity underlies several human diseases. Peptidic PTH1R antagonists and inverse agonists have therapeutic potential in treating these diseases, but their poor pharmacokinetics and pharmacodynamics undermine their in vivo efficacy. Herein, we report the use of a backbone-modification strategy to design a peptidic PTH1R inhibitor that displays prolonged activity as an antagonist of wild-type PTH1R and an inverse agonist of the constitutively active PTH1R-H223R mutant both in vitro and in vivo. This peptide may be of interest for the future development of therapeutic agents that ameliorate PTH1R malfunction.

Background: Multiple myeloma (MM) remains a formidable clinical challenge due to its high relapse rate and resistance to existing therapies. Estrogen-related receptor gamma (ERRγ), a nuclear receptor critical for cellular energy metabolism, has been implicated in various cancers. but its role in MM remains unclear.

Former studies indicate that nuclear receptor subfamily 4 group A member 2 (Nurr1, NR4A2), a transcription factor, is regarded as a potential therapeutic target for central nervous system diseases, and many studies have focused on the development and optimization of agonists of Nurr1. Recent studies have shown that Nurr1 is upregulated in many other diseases. However, there is still a lack of effective inverse Nurr1 agonists as a therapeutic strategy or as pharmacological tools to counteract the receptor's inherent activity.

Ethnopharmacological Relevance: Liquorice (Gancao), a classic Chinese herb, has been historically prescribed for inflammation and gastrointestinal disorders. Its bioactive flavonoid liquiritigenin (4',7-dihydroxyflavone) exhibits anti-inflammatory properties, yet its efficacy against acute pancreatitis (AP) remains unexplored.
Aim: To systematically investigate the therapeutic potential of liquiritigenin against AP and decipher its estrogen receptor beta (ERβ)-mediated mitochondrial regulatory mechanisms.

The etiology of complex diseases such as metabolic-associated steatohepatitis (MASH) presents significant challenges for therapeutic discovery. Here, we developed ComplexDnet, a transcriptome- and network-integrated framework to prioritize disease-relevant targets. Applied across eight cancer types, ComplexDnet achieved an average recall of 77.
