摘要

A compound, or a pharmaceutically acceptable salt thereof, having a structure of: Formula A wherein A is a ring; Y1 and Y2 are each independently N or C with the proper valency; X1 and X2 are each independently -NH-, -0-, -CH2-0-, -NH-CH2-, or -N(CH3)-CH2-, provided that when at least one of X1 and X2 is -CH2-0-, -NH-CH2-, or -N(CH3)-CH2- then the - CH2- is directly connected to A; a and b are each independently 0 or 1; c and d are each independently 0 or 1; Z1 and Z2 are each independently a heterocyclic; and R1 and R2 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 Y1 and Y2 are each C, then a is 1 and b is 1; provided that if Y1 and Y2 are each N, then a is 0 and b is 0; provided that if Y1 is N and Y2 is C, then a=0 and b=l; provided that if Y1 is C and Y2 is N, then a=l and b=0; provided that if c=0 and d=0, then R1 and R2 are both amino; provided that if c is 1 and d is 1, then both R1 and R2 are not amino; provided that if c is 0 and d is 1, then R1 is amino and R2 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 R2 is amino and R1 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.
