Tau Protein

Tau protein compounds act on the microtubule-associated protein tau (MAPT) and its aggregation in neurodegeneration. Tau was described in 1975 as a protein factor essential for microtubule assembly. In 1986 abnormally phosphorylated tau was identified in the cytoskeletal pathology of Alzheimer disease. Assembly of tau into paired helical filaments depends on the hexapeptide motif VQIVYK at residues 306 to 311, which forms beta structure. Tau Peptide (306-317) spans this motif and serves as a substrate in aggregation assays. TRx0237 (LMTX) mesylate, PE859 and nimbin are listed as inhibitors of tau aggregation. QC-01–175 is a proteolysis targeting chimera (PROTAC) that degrades tau, whereas MRL828 is an autophagosome-tethering compound (ATTEC) for tau.

    Simufilam hydrochloride

    Synonyms: PTI-125 hydrochloride

    Simufilam hydrochloride is an orally active modulator of filamin A (FLNA) that targets neuronal signaling pathways. This compound restores NMDAR signaling and Arc expression while inhibiting dysregulated mTOR activity. Additionally, it enhances insulin sensitivity and mitigates Aβ42-induced neuroinflammation and tau protein hyperphosphorylation. Simufilam hydrochloride is applicable in research related to Alzheimer's disease, particularly in understanding the underlying mechanisms of neurodegeneration.

    Simufilam

    Synonyms: PTI-125

    Simufilam is an orally active modulator of filamin A (FLNA) that restores NMDA receptor (NMDAR) signaling and Arc expression. It effectively inhibits overactive mTOR signaling by restoring the normal conformation of FLNA, which results in improved insulin sensitivity and a reduction in Aβ42-induced neuroinflammation and tau protein hyperphosphorylation. This compound is particularly valuable for research applications focused on Alzheimer's disease and related neurodegenerative disorders.

    PTC-700

    PTC-700 is a potent modulator of microtubule-associated protein tau (MAPT) splicing. This compound effectively reduces 4-repeat isoform MAPT levels in P301L and S305N neuronal models, exhibiting EC50 values of 1.3-1.8 nM and 0.5-2.6 nM, respectively. PTC-700 is utilized in research applications focused on tauopathies and neurodegenerative disorders, contributing to the understanding of tau protein dynamics and potential therapeutic avenues.
