    • (b) PDE4 enzymatic assay (for further details see ESI): The inhibition of PDE4 enzyme was measured using PDElight HTS cAMP phosphodiesterase assay kit (Lonza) according to manufacturer's recommendations. Briefly, 10 ng of in house purified PDE4B or 0.5 ng commercially procured PDE4D enzyme was pre-incubated either with DMSO (vehicle control) or compound for 15 min before incubation with the substrate cAMP (5 μM) for 1 h. The reaction was halted with stop solution and reaction mix was incubated with detection reagent for 10 min in dark. Dose-response studies were performed at 13 different concentrations ranging from 200 μM to 0.001 μM. Luminescence values (RLUs) were measured by a Multilabel plate reader (Perklin-Elmer 1420 Multilabel counter).The percentage of inhibition was calculated using the following formula:% inhibition = [(RLU of vehicle control - RLU of inhibitor)/(RLU of vehicle control)] × 100.
