or a pharmaceutically acceptable ester or acid addition salt thereof,
wherein
R¹ denotes hydrogen, an unsubstituted or substituted hydrocarbon group, a heterocyclyl group, or an acyl group;
R³ denotes hydrogen or hydroxy;
R⁶ denotes hydrogen or methyl;
one of R⁷ and R⁸ denotes hydrogen, hydroxy, alkoxy,alkanoyloxy, amino, substituted amino, or a group of the formula R⁹-SO₂-O-, and the other of R⁷ and R⁸ denotes hydrogen, or
R⁷ and R⁸ together denote an oxo group, an oxime group, or a substituted oxime group; and
R⁹ denotes an organic group,
possess improved acid stability, compared with erythromycin A, whilst retaining good antibacterial activity.
