Claims38
A method for inhibiting APOBEC3G activity in a mammal, said method comprising administering to said mammal a therapeutically effective amount of a compound of Formula (I):
- wherein:
- R1, R2, and R4 are independently chosen from H, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, and substituted or unsubstituted alkynyl;
- R3 is chosen from H and ORS;
- and
- R5 is chosen from H and substituted or unsubstituted alkyl;
- or a pharmaceutically acceptable salt form thereof;
- a therapeutically effective amount of a compound of Formula (II):
- wherein:
- R6, R7, and R8 are independently chosen from H and substituted or unsubstituted alkyl;
- and
- R9 is chosen from a substituted or unsubstituted cycloalkyl and substituted or unsubstituted heterocycloalkyl;
- or a pharmaceutically acceptable salt form thereof;
- a therapeutically effective amount of a compound of Formula (III):
- wherein:
- R10 and R11 are independently chosen from H and substituted or unsubstituted alkyl;
- and
- R12 is chosen from:
- (CH2)nC(O)OR22, and substituted or unsubstituted alkylaryl;
- wherein:
- R13 is chosen from C(O)NR14R15, C(O)OR14, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl;
- R14 is chosen from H and substituted or unsubstituted alkyl;
- R15 is a substituted or unsubstituted alkylaryl;
- R16 is chosen from H and substituted or unsubstituted alkyl;
- R17 is chosen from H and C(O)OR20;
- R18 and R19 are chosen from H, C(O)R21, and amino;
- R20 and R21 are independently chosen from H and substituted or unsubstituted alkyl;
- R22 is H or a substituted or unsubstituted alky;
- and
- n is an integer from 1 to 6;
- wherein if R16 is methyl, then at least one of R18 and R19 is not H;
- or a pharmaceutically acceptable salt form thereof;
- or a therapeutically effective amount of a compound of Formula (IV):
- wherein:
- R23 and R24 are independently chosen from H and substituted or unsubstituted alkyl;
- R25 is a substituted or unsubstituted heterocycloalkyl and R26 is H, or R25 and R26 come together to form a substituted or unsubstituted cycloalkyl or a substituted or unsubstituted heterocycloalkyl;
- or a pharmaceutically acceptable salt form thereof.

A method for inhibiting APOBEC3G activity in a mammal, said method comprising administering to said mammal a therapeutically effective amount of a compound chosen from:
- or a pharmaceutically acceptable salt form thereof.
A method for inhibiting APOBEC3G activity in a mammal, said method comprising administering to said mammal a therapeutically effective amount of a compound chosen from:
- or a pharmaceutically acceptable salt form thereof.
A method of identifying inhibitors of HIV-1 mutation, said method comprising measuring HIV-1 mutation rate in the presence and absence of an inhibitor of the anti-retroviral activity of APOBEC3G
A method of identifying inhibitors of the anti-retroviral activity of APOBEC3G, said method comprising
- a) assaying cytosine deaminase activity of APOBEC3G. in the presence and absence of a compound, wherein said compound is identified as an inhibitor of cytosine deaminase activity if cytosine deaminase activity is reduced in the presence of said compound;
- and
- b) assaying replication of Vif-deficient HIV-1 in an APOBEC3G-expressing human T cell line in the presence of said inhibitor of cytosine deaminase activity, wherein said compound is identified as an inhibitor of the anti-retroviral activity ofAPOBEC3G if Vif-deficient HIV-1 replicates in said APOBEC3G-expressing human T cell line.
