Clobetasol propionate

It produces inflammatory action by acting on induction of phospholipase A2 inhibitory protein which is called as lipocortins. These proteins produce control over biosynthesis of mediators of inflammation i.e PGs and leukotrienes. This causes inhibition of arachidonic acid. Clobetasol binds to glucocorticoid receptor which complexes, enters the nucleus of cell and modifies genetic transcription.

Fuscidic acid

The drug produces its bacteriostatic action by inhibiting the synthesis of protein by disrupting the translocation of peptide subunits and elongation in the peptide chain of the bacteria.
