Boldine is an aporphine alkaloid telomerase (telomerase) inhibitor (IC50 of 0.17 μM for TERT) and a pannexin/connexin hemichannel blocker, with oral activity and blood-brain barrier permeability. Boldine inhibits telomerase activity through direct interaction with the telomerase ribonucleoprotein and non-competitive binding near the TERT active site, and downregulates hTERT mRNA while shifting alternative splicing toward non-functional transcripts. Boldine blocks Panx1, Cx43, Cx26, and Cx30 hemichannels as well as P2X7 receptor-mediated calcium influx. Boldine exhibits antioxidant, anti-inflammatory, antiproliferative, and cytotoxic activities by scavenging ROS, inhibiting NFκB, dephosphorylating SGK1, and reducing TNF-alpha levels. Boldine can be used in research on breast cancer, Alzheimer's disease, glioblastoma, diabetes, and spinal cord injury .

Kallikrein

Research Areas:  

Cardiovascular Disease

Sebetralstat (KVD900) is an orally active and selective plasma kallikrein inhibitor, with an IC50 of 6.0 nM and a Ki of 3.0 nM against the human target. Sebetralstat binds to the active site of plasma kallikrein, inducing a conformational flip of Trp215 to form a U-shaped conformation; its P1 group interacts with the S1 pocket through hydrophobic interactions and displacement of high-energy water molecules, independent of the Asp189 ionic bond. Sebetralstat inhibits plasma kallikrein-kinin system activation in whole plasma, rapidly relieves laryngeal and abdominal attack symptoms of hereditary angioedema (HAE-C1INH), and reduces attack severity. Sebetralstat can be used in research related to hereditary angioedema (HAE) .
