A compound, or a pharmaceutically acceptable salt thereof, having a structure of:
wherein A is a ring;
Y
1
and Y
2
are each independently N or C with the proper valency;
X
1
and X
2
are each independently —NH—, —O—, —CH
2
—O—, —NH—CH
2
—, or —N(CH
3
)—CH
2
—, provided that when at least one of X
1
and X
2
is —CH
2
—O—, —NH—CH
2
—, or —N(CH
3
)—CH
2
— then the —CH
2
— is directly connected to A;
a and b are each independently 0 or 1;
c and d are each independently 0 or 1;
Z
1
and Z
2
are each independently a heterocyclic; and
R
1
and R
2
are each independently optionally substituted alkyl, optionally substituted aralkyl, optionally substituted cycloalkyl, amino, optionally substituted heteroaralkyl, optionally substituted alkylalkoxy, optionally substituted alkylaryloxy, optionally substituted aryl, optionally substituted heteroaryl, or optionally substituted heterocycloalkyl;
provided that if Y
1
and Y
2
are each C, then a is 1 and b is 1;
provided that if Y
1
and Y
2
are each N, then a is 0 and b is 0;
provided that if Y
1
is N and Y
2
is C, then a=0 and b=1;
provided that if Y
1
is C and Y
2
is N, then a=1 and b=0;
provided that if c=0 and d=0, then R
1
and R
2
are both amino;
provided that if c is 1 and d is 1, then both R
1
and R
2
are not amino;
provided that if c is 0 and d is 1, then R
1
is amino and R
2
is optionally substituted alkyl, optionally substituted aralkyl, optionally substituted cycloalkyl, optionally substituted heteroaralkyl, optionally substituted alkylalkoxy, optionally substituted alkylaryloxy, optionally substituted aryl, optionally substituted heteroaryl, or optionally substituted heterocycloalkyl; and
provided that if c is 1 and d is 0, then R
2
is amino and R
1
is optionally substituted alkyl, optionally substituted aralkyl, optionally substituted cycloalkyl, optionally substituted heteroaralkyl, optionally substituted alkylalkoxy, optionally substituted alkylaryloxy, optionally substituted aryl, optionally substituted heteroaryl, or optionally substituted heterocycloalkyl.
