Claim 11:
12. A compound having the formula I:, or a pharmaceutically acceptable salt or stereoisomer thereof,
wherein:
R1 is:
(a) NHCH2CH3, wherein the CH2CH3 is substituted with one NR4R5 substituent;
(b) NHCH2phenyl, wherein the phenyl of CH2phenyl is substituted with one C1 substituent;
(c) NH(phenyl), wherein the phenyl is substituted with one, two, or three substituents independently selected from the group consisting of halogen, C1-C6 alkyl, C(halo)3, NR4R5, OH, and OC1-C6 alkyl; or
(d) NH(2-methylpyridin-4-yl);
R2 is C(O)OH;
R3 is H;
each R4 is an independently selected linear C1-C6 alkyl; and
each R5 is an independently selected linear C1-C6 alkyl; or
any R4 and R5, taken together with the nitrogen atom to which they are attached, independently forms a nitrogen-containing heterocyclyl, wherein each nitrogen-containing heterocyclyl is optionally and independently substituted with one, two, or three substituents independently selected from the group consisting of halogen, C1-C6 alkyl, C1-C6 trihaloalkyl, OH, and OC1-C6 alkyl.
