Phenyl indole allosteric inhibitors of P97 ATPase
The present invention is directed to methods of inhibiting p97 and compounds and compositions useful in such methods. Diseases and conditions the can be treated with the compounds and compositions of the invention include, but are not limited to, cancer and neurodegenerative disorders susceptible to treatment by inhibition of p97.
1. A method of inhibiting p97 in a subject, comprising administering to the subject a therapeutically effective amount of a compound of formula II or a therapeutically effective amount of a pharmaceutical composition comprising a compound of formula II and at least one pharmaceutically acceptable excipient:
or a pharmaceutically acceptable salt thereof, wherein:
R 1 is H, D, halo, cyano, hydroxyl, nitro, —C(O)NR 5 R 6 , —C(O)OR 5 , —N═N + ═N − , C 1 -C 3 alkyl, C 1 -C 3 alkoxy, —S(O) 2 NR 5 R 6 , —S(O) 2 R 5 , —OCZ 3 , —OCHZ 2 , —OCH 2 Z, —SZ 3 , —SCZ 3 , or S(Z) 5 ;
each of R 5 or R 6 is independently H, D, C 1 -C 5 alkyl, or C 1 -C 3 alkoxy optionally substituted with one or more halo;
Z is a halo;
R 2 is H, D, halo, cyano, C 1 -C 3 alkyl optionally substituted with one or more halo;
m is 0, 1, 2, 3, or 4;
R 3 is H, D, or C 1 -C 3 alkyl optionally substituted by one or more halo;
each R 3′ is independently CH or N, and at least one R 3′ is N;
M is C 1 -C 6 alkyl;
Y is a bond, CH, CH 2 , N, NH, O, or S;
L 2 is C 1 -C 5 alkyl optionally further including a cycloalkyl group or optionally substituted with one or more oxo;
p is 0, 1, 2, 3, or 4; and
denotes a single or double bond.
2. A method of treating non-small cell lung carcinoma in a subject,
the method comprising administering to the subject a therapeutically effective amount of a compound of formula II or a therapeutically effective amount of a pharmaceutical composition comprising a compound of formula II and at least one pharmaceutically acceptable excipient:
or a pharmaceutically acceptable salt thereof, wherein:
R 1 is H, D, halo, cyano, hydroxyl, nitro, —C(O)NR 5 R 6 , —C(O)OR 5 , —N═N + ═N − , C 1 -C 3 alkyl, C 1 -C 3 alkoxy, —S(O) 2 NR 5 R 6 , —S(O) 2 R 5 , —OCZ 3 , —OCHZ 2 , —OCH 2 Z, —SZ 3 , —SCZ 3 , or S(Z) 5 ;
each of R 5 or R 6 is independently H, D, C 1 -C 5 alkyl, or C 1 -C 3 alkoxy optionally substituted with one or more halo;
Z is a halo;
R 2 is H, D, halo, cyano, C 1 -C 3 alkyl optionally substituted with one or more halo;
m is 0, 1, 2, 3, or 4;
R 3 is H, D, or C 1 -C 3 alkyl optionally substituted by one or more halo;
each R 3′ is independently CH or N, and at least one R 3′ is N;
M is C 1 -C 6 alkyl;
Y is a bond, CH, CH 2 , N, NH, O, or S;
L 2 is C 1 -C 5 alkyl optionally further including a cycloalkyl group or optionally substituted with one or more oxo,
p is 0, 1, 2, 3, or 4; and
denotes a single or double bond.
3. The method of claim 1 or 2 , wherein R 1 is H, D, halo, cyano, hydroxyl, nitro, or —N═N + ═N − .
4. The method of claim 1 or 2 , wherein M is a C 1 -C 3 alkyl.
5. The method of claim 1 or 2 , wherein both R 3′ are N.
6. The method of claim 1 or 2 , wherein L 2 is a C 2 alkyl.
7. The method of claim 1 or 2 , wherein R 1 is halo, cyano, N(O) 2 , hydroxyl, or —C(O)NR 5 R 6 .
8. The method of claim 1 or 2 , wherein p=0.
