R³ is CO₂H, SO₃H, CONHSO₂R⁸, or a group of formula
W is (CH₂)n, S, SO, SO₂;
Y is CHR⁷, NR⁴, O, S, SO, or SO₂;
Z is NR⁶, CHR⁷, or CH; or
W and Y together are HC=CH or C≡C, or Y and Z together are HC=CH or C≡C;
R⁴ is hydrogen, C₁-C₄ alkyl, phenyl, or acyl;
R⁵ is hydrogen, C₁-C₄ alkyl, CF₃, phenyl, hydroxy, amino, bromo, iodo, or chloro;
R⁶ is acyl;
R⁷ is independently hydrogen, C₁-C₄ alkyl, phenyl, or substituted phenyl;
R⁸ is C₁-C₄ alkyl or tetrazole-5-yl; and
n is 0, 1, or 2;
provided that when Y is NR⁴, O, S, SO, or SO₂, W is (CH₂)n and Z is CHR⁷ or CH;
further provided that when W is S, SO, or SO₂, Y is CHR⁷, Z is CHR⁷ or CH, or Y and Z together are HC=CH or C≡C;
further provided that when W and Z are CH₂, Y is not S;
further provided that when W and Y together are HC=CH or C≡C, Z is CHR⁷;
or a pharmaceutically acceptable salt thereof.
