Online Published on 10 October, 2023. Abstract Background The phosphodiesterase (PDE)7B, belonging to family PDE7 has high affinity and specificity for cyclic adenosine monophosphate (cAMP). This was reported to regulate a range of physiological functions. Inhibition of this enzyme was found to have therapeutic effects. The present study aims to evaluate the inhibition of PDE7B by vasicine, using Nuclear magnetic resonance (NMR) spectroscopy. Materials and Methods The 1D NMR based time series experiment was performed; the initial and the final spectra were compared for the formation of cAMP in the presence and absence of the inhibitor. Results The PDE7B was inhibited completely by vasicine and no formation of AMP was seen in the time series spectra. Conclusion NMR spectroscopy method revealed the PDE7B inhibitory activity of vasicine which may be considered as a therapeutic agent for diseases regulated by cAMP.
