Design, Synthesis, and Biological Evaluation of 3,4-Dihydroisoquinolin-1()-one Derivatives as Protein Arginine Methyltransferase 5 Inhibitors for the Treatment of Non-Hodgkin's Lymphoma.

Through catalyzing the transfer of methyl groups onto the guanidinium of arginine, protein arginine methyltransferase 5 (PRMT5) was essential to the cell growth of cancer cells. By utilizing a scaffold hopping strategy, a novel series of 3,4-dihydroisoquinolin-1()-one derivatives were designed and synthesized. Through a systematic SAR study, demonstrated excellent PRMT5 inhibitory activity, potent antiproliferative activity against Z-138, favorable pharmacokinetic profiles, and low hERG toxicity.

Design, Synthesis, and Biological Activities Evaluation of Type I FLT3 Inhibitors for the Treatment of Acute Myeloid Leukemia.

The abnormal overexpression of FLT3 kinase is intimately associated with pathogenesis of acute myeloid leukemia (AML), positioning FLT3 inhibitors as pivotal therapeutic agents. Despite the availability of three FDA-approved FLT3 inhibitors, their clinical utility is hampered by resistance stemming from tyrosine kinase domain (TKD) mutations. Through an integrative analysis of case studies, we identified a potential advantage of type I FLT3 inhibitors in overcoming TKD mutation-induced resistance.

Discovery of RORγ Allosteric Fluorescent Probes and Their Application: Fluorescence Polarization, Screening, and Bioimaging.

Retinoic acid receptor-related orphan receptor γ (RORγ) acts as a crucial transcription factor in Th17 cells and is involved in diverse autoimmune disorders. RORγ allosteric inhibitors have gained significant research focus as a novel strategy to inhibit RORγ transcriptional activity. Leveraging the high affinity and selectivity of RORγ allosteric inhibitor (), this study presents the design, synthesis, and characterization of 11 allosteric fluorescent probes.

Enhanced molecular recognition for imprinted monolithic column containing polyhedral oligomeric silsesquioxanes by dendritic effect of mesoporous molecular sieve scaffolds.

The dendritic effect of nano mesoporous molecular sieve was first used to enhance molecular recognition of molecularly imprinted polymers (MIPs)-based polyhedral oligomeric silsesquioxanes (POSS). In this study, the MIPs were made using S-naproxen (S-NAP) as template molecule, 4-vinylpyridine (4-VP) as functional monomer, ethylene glycol dimethacrylate as cross-linker, 1-butyl-3-methylimidazoliumtetrafluoroborate ([BMIM]BF)/DMSO as binary porogens, 1-propylmethacrylate-heptaisobutyl substituted as POSS monomer, and mesoporous molecular sieve (Mobil composition of matter No. 41, MCM-41) as dendritic scaffold.

Characteristics of vascular supply to uterine leiomyoma: an analysis of digital subtraction angiography imaging in 518 cases.

Objectives: To investigate the characteristics of the vascular supply to uterine leiomyomas based on digital subtraction angiography.

Methods: The feeding artery, vascularity of uterine leiomyoma and visualisation of the ovarian vessel network were studied in 518 patients undergoing uterine artery embolisation (UAE). Mean patient age was 38.
