Galande S, Ambhore S, Jena L, Kumar S., In Silico inhibitors for PTP1B as a drug target for diabetes, Onl J Bioinform, 16 (2): 121-128, 2015.Tyrosine phosphatases-1B (PTP1B) have been identified as a drug target for diabetes as they regulate tyrosine phosphorylation-dependent signaling events. We describe natural inhibitors against PTP1B by virtual screening using PyRx0.8 and compared its binding affinity with PTP1B inhibitor FTY (Deoxy-Difluoromethelene-Phosphotyrosine). SN00158250 (16-hydroxy-3,5-dioxa-10-aza pentacyclo [²,.0.0¹³,¹] nonadeca-1,6,8(19),11,13,15,17-heptaen-9-one),  has been identified as an effective inhibitor for  PTP1B. Functional groups of FTY were added to SN00158250: docking with AutoDock4.2 revealed another 2 compounds able to interact with PTP1B.
