Arsenic trioxide for treatment of PIN1-associated disorders
View Patent ↗The present invention relates to the treatment of Pin1-associated disorders (e.g., disorders characterized by elevated Pin1 activity) with arsenic trioxide, optionally in combination with a retinoic acid compound. Pin1-associated disorders may include, for example, proliferative disorders (e.g., cancers), inflammatory conditions, and autoimmune disorders associated with aberrant levels of Pin1 activity.
1. A method of inhibiting, reducing, or reversing the effect of increased Pin1 activity in one or more cells within a subject characterized as having a Pin1-associated disorder, said disorder resulting from increased Pin1 activity, said method comprising:
administering, as treatment for said increased Pin1 activity in said one or more cells within said subject, arsenic trioxide alone, or arsenic trioxide and a retinoic acid compound;
wherein said administration to said subject is sufficient to inhibit, reduce, or reverse the effect of increased Pin1 activity in said one or more cells within said subject,
wherein said increased Pin1 activity is due to a somatic mutation of Pin1, wherein said somatic mutation comprises one or more of the following:
a) Q33K;
b) E100D;
c) R36P;
d) G39C;
e) T143M; or
f) E145K.
