This invention provides novel indenone derivatives, their pharmaceutical formulations and their use for the inhibition of leukocyte adherence to cells. The indenone derivative is of the formula
where R1 and R2 are each independently hydrogen, hydroxy, nitro, amino, C1-C4 alkyl, C1-C4 alkoxy or halo;
R3 is hydrogen, hydroxy, C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, C3-C6 cycloalkyl, C1-C6 alkoxy, halo, halo (C1-C6 alkyl), unsubstituted or substituted phenyl; and
R4 is hydrogen or C1-C4 alkyl, or a pharmaceutically acceptable salt or solvate thereof; provided that,
when R1, R2 and R4 are each hydrogen, R3 is other than C1-C4 alkyl, halo(C1-C4 alkyl), cyclopropyl or phenyl.
