Definitions

  • the accumulated pathologic Tau protein is caused by a central nervous system disease.
  • the 2,4-DSPBN or pharmaceutically acceptable salt thereof is administered to the subject at least two months, at least three months, at least six months, at least nine months, at least twelve months, or 1-60 months after onset of the central nervous system disease.
  • cerebrospinal fluid of the subject comprises at least 0.05 ng/ml, or at least 0.07 ng/ml, or at least 0.1 ng/ml, or at least 0.15 ng/ml, or at least 0.2 ng/ml, or at least 0.25 ng/ml, or at least 0.3 ng/ml, or at least 0.35 ng/ml, or at least 0.4 ng/ml, or at least 0.45 ng/ml, or at least 0.5 ng/ml, of accumulated pathologic Tau protein.
  • Figure 1 shows T22 positive neuron counting and statistical analyses in the spiral ganglion (SG) after noise exposure. Rats were exposed to 115 dB SPL octave band noise for one hour. One group of rats were treated with 2,4-DSPBN and NAC (300 mg/kg of each) one hour after noise exposure and twice /day for the next two days (total 5 doses, the N/T group) while another group of rats were treated with vehicle (saline) only (the N group). One group of rats without noise exposure served as normal controls (the NC group). Animals were euthanized at 7- and 21 -days after noise exposure, and cochlear tissues were processed for immunostaining.
  • 2,4-disulfonyl a-phenyl tertiary butyl nitrone is also referred to as 2,4-disulfonyl PBN, 2,4-DSPBN, NXY-059, HPN-07, or CAS 168021-79-2. It has the following structure:
  • 2,4-DSPBN is described in detail by U.S. Pat. No. 5,488,145, which is incorporated herein by reference.
  • the salts of 2,4-DSPBN may also be used for reducing accumulated pathologic Tau protein in a manner similar to the use of 2,4- DSPBN as described herein.
  • the nitrone compound is selected from phenyl butyl nitrone (PBN) and its derivatives. In some embodiments, the nitrone compound is PBN. In some embodiments, the nitrone compound is 4-hydroxy-a-phenyl butyl nitrone (4-OHPBN). In some embodiments, the nitrone compound is 2-sulfonyl-a-phenyl tertiary butyl nitrone (S-PBN).
  • PBN phenyl butyl nitrone
  • S-PBN 2-sulfonyl-a-phenyl tertiary butyl nitrone
  • the method further comprises administering a Tau aggregation inhibitor.
  • the Tau aggregation inhibitor can be a covalent or non-covalent inhibitor.
  • Non-limiting examples of Tau aggregation inhibitors include curcumin, molecular tweezers (e.g., CLR01), phthalocyanine tetrasulfonate, oleocanthal, cinnamaldehyde, baicalein, isoprenaline, dopamine, dobutamine, levodopa, levodopa/carbidopa, trimetoquinol, hexoprenaline, methyldopa, and droxidopa.
  • an effective amount of 2,4-DSPBN or its pharmaceutically acceptable salt and optionally NAC are administered to a human patient suffering from CTE, wherein the 2,4-DSPBN or its pharmaceutically acceptable salt and the optional NAC reduce the amount of accumulated pathologic Tau proteins in the central nervous system to a level sufficient to deliver a therapeutic benefit to the patient against CTE.
  • a further aspect of the invention relates to a method for reducing accumulated pathologic Tau protein in a patient suffering from progressive supranuclear palsy (PSP).
  • cerebrospinal fluid of the patient contains at least 0.05 ng/ml, or at least 0.07 ng/ml, or at least 0.1 ng/ml, or at least 0.15 ng/ml, or at least 0.2 ng/ml, or at least 0.25 ng/ml, or at least 0.3 ng/ml, or at least 0.35 ng/ml, or at least 0.4 ng/ml, or at least 0.45 ng/ml, or at least 0.5 ng/ml, of accumulated pathologic Tau protein.
  • an effective amount of 2,4-DSPBN or its pharmaceutically acceptable salt and optionally NAC are administered to a human patient suffering from FTD, wherein the 2,4-DSPBN or its pharmaceutically acceptable salt and the optional NAC reduce the amount of accumulated pathologic Tau proteins in the central nervous system to a level sufficient to deliver a therapeutic benefit to the patient against FTD.
  • an effective amount of 2,4-DSPBN or its pharmaceutically acceptable salt and optionally NAC are administered to a human patient suffering from HSD, wherein the 2,4-DSPBN or its pharmaceutically acceptable salt and the optional NAC reduce the amount of accumulated pathologic Tau proteins in the central nervous system to a level sufficient to deliver a therapeutic benefit to the patient against HSD.
  • a further aspect of the invention relates to a method for reducing accumulated pathologic Tau protein in a patient suffering from multiple system atrophy (MSA).
  • cerebrospinal fluid of the patient contains at least 0.05 ng/ml, or at least 0.07 ng/ml, or at least 0.1 ng/ml, or at least 0.15 ng/ml, or at least 0.2 ng/ml, or at least 0.25 ng/ml, or at least 0.3 ng/ml, or at least 0.35 ng/ml, or at least 0.4 ng/ml, or at least 0.45 ng/ml, or at least 0.5 ng/ml, of accumulated pathologic Tau protein.
  • an effective amount of 2,4-DSPBN or its pharmaceutically acceptable salt and optionally NAC are administered to a human patient suffering from NPC, wherein the 2,4-DSPBN or its pharmaceutically acceptable salt and the optional NAC reduce the amount of accumulated pathologic Tau proteins in the central nervous system to a level sufficient to deliver a therapeutic benefit to the patient against NPC.
