We describe the connection between single field inflationary models and the primordial power spectrum, discuss in particular the spectral index and its running. We consider then the observational constraints on a specific class of models (the running-mass inflationary model), which show a particular scale-dependence of the spectral index, from the WMAP first data release of the CMB anisotropy and from new clustering data from the SLOAN survey.
