Synthesis, biological evaluation and docking studies of 4-amino substituted 1H-pyrazolo[3,4-d]pyrimidines
摘要:
The synthesis of new 4-amino substituted pyrazolo[3,4-d]pyrimidines along with their activity in cell-free enzymatic assays on Src and Abl tyrosine kinases is reported. Some compounds emerged as good dual inhibitors of the two enzymes, showed antiproliferative effects on two Bcr-Abl positive leukemia cell lines K-562 and KU-812, and induced apoptosis, as demonstrated by the PARP assay. Docking studies have been also performed to analyze the binding mode of compounds under study and to identify the structural determinants of their interaction with both Src and Abl.

A family of pyrazolo[3,4-d]pyrimidine derivatives (SPPs) with different substituents on the pyrimidine and pyrazolo rings have been characterized with a panel of tests demonstrating their effects in cell proliferation, toxicity, apoptosis and inhibition of virus replication. We have identified compounds and molecular structures suitable for the treatment of viral infection because they have antiviral activity, anti-proliferative activity or, preferably, both so that, as a single molecule, they both limit T cell hyperactivation and inhibit virus replication. These compounds are not toxic at effective concentrations and are poorly apoptotic. Other nontoxic compounds within this family with excellent anti-proliferative and apoptotic features are potentially effective as anti-cancer drugs.

Hit Identification and Biological Evaluation of Anticancer Pyrazolopyrimidines Endowed with Anti-inflammatory Activity
Inhibiting COX: A small library of pyrazolopyriminines endowed with antiproliferative action was submitted to virtual screening against two COX isoforms. Three compounds were identified in silico as potentially selective COX‐2 inhibitors. The biological assay confirmed one of them to be a COX‐2 inhibitor with potency and selectivity comparable to known drugs.
