Tropomyosin receptor kinases (Trks), a transmembrane receptor tyrosine kinases, have attracted more and more attention as a drug target. Here we reported the structure-based synthesis and biological evaluation of novel pyrazolo[1,5-a]pyrimidine derivatives as Trk inhibitors, which exhibited potent Trk inhibitory activities. Particularly, compounds 8a, 8f, 9a, 9b and 9f (IC50 less then 5 nM) showed significant inhibitory potency against Trk.Four compounds, hericerin (1), isohericerinol A (2), N-de-phenylethyl isohericer
