Claims20
A compound according to formula (I):
- wherein:
- R1 is selected from the group consisting of H, OH, and —(OCH2CH2)xOH;
- p1 X is an integer from 1 to 6;
- and
- R2, R2′, R3, and R3′ independently are selected from the group consisting of H, C3-8cycloalkyl, and combinations thereof, or R2 and R2′ may be joined together to form a pyridinyl or pyranyl and R3 and R3′ may be joined together to form a pyridinyl or pyranyl;
- or an N-oxide, crystalline form, hydrate, or pharmaceutically acceptable salt thereof;
- with the proviso that the compound is not
A method for inducing ferroptosis in a cell comprising contacting the cell with an effective amount of a compound having the structure of formula (I):
- wherein:
- R1 is selected from the group consisting of H, OH, and —(OCH2CH2)xOH;
- X is an integer from 1 to 6;
- and
- R2, R2′, R3, and R3′ independently are selected from the group consisting of H, C3-8cycloalkyl, and combinations thereof, or R2 and R2′ may be joined together to form a pyridinyl or pyranyl and R3 and R3′ may be joined together to form a pyridinyl or pyranyl;
- or an N-oxide, crystalline form, hydrate, or pharmaceutically acceptable salt thereof.
A method for decreasing GPX4 in a cell, comprising contacting the cell with an effective amount of a compound having the structure of formula (I):
- wherein:
- R1 is selected from the group consisting of H, OH, and —(OCH2CH2)xOH;
- X is an integer from 1 to 6;
- and
- R2, R2′, R3, and R3′ independently are selected from the group consisting of H, C3-8cycloalkyl, and combinations thereof, or R2 and R2′ may be joined together to form a pyridinyl or pyranyl and R3 and R3′ may be joined together to form a pyridinyl or pyranyl;
- or an N-oxide, crystalline form, hydrate, or pharmaceutically acceptable salt thereof.
