Based on 10 publication(s) in Google Scholar
TMPyP tetrachloride is a quadruplex-specific ligand. TMPyP tetrachloride inhibits the interaction between G-quadruplexes and IGF-1. TMPyP tetrachloride is a telomerase inhibitor and inhibits cancer cells proliferation. TMPyP tetrachloride is also a stabilizer of nucleic acid secondary structure and an acetylcholinesterase inhibitor. Besides, TMPyP tetrachloride has antiviral activity against SARS-CoV-2.

TMPyP tetrachloride purchased from MedChemExpress. Usage Cited in: Nucleic Acids Res. 2026 Jan 14;54(2):gkaf1481. [Abstract]
Treatment with TMPyP4 tosylate (2 μM; 26 h) resulted in a 14.18% reduction in the HDAC1 frameshifting ratio in HEK293T cells, whereas the mut1 rG4 mutant exhibited only a minimal reduction (1.88%) compared with the control group.
TMPyP tetrachloride purchased from MedChemExpress. Usage Cited in: Nucleic Acids Res. 2026 Jan 14;54(2):gkaf1481. [Abstract]
The G4-destabilizing porphyrin TMPyP4 tosylate (1-100 μM) induced a concentration-dependent shift in the spectral peak, indicating a transition of the higher order HDAC1 RNA structure to a linear form. Moreover, the high concentration (100 μM) of TMPyP4 disrupted the standard CD spectrum of the G4 structure.
