1 Structure guided design of potent and selective ponatinib-based hybrid inhibitors for RIPK1. ponatinib receptor interacting serine/threonine kinase 1 Homo sapiens
2 In the current work, we report that the Bcr-Abl inhibitor and anti-leukemia agent ponatinib is also a first-in-class dual inhibitor of RIPK1 and RIPK3. ponatinib receptor interacting serine/threonine kinase 1 Homo sapiens
3 Ponatinib potently inhibited multiple paradigms of RIPK1- and RIPK3-dependent cell death and inflammatory tumor necrosis factor alpha (TNF-alpha) gene transcription. ponatinib receptor interacting serine/threonine kinase 1 Homo sapiens
4 We further describe design strategies that utilize the ponatinib scaffold to develop two classes of inhibitors (CS and PN series), each with greatly improved selectivity for RIPK1. ponatinib receptor interacting serine/threonine kinase 1 Homo sapiens
5 In particular, we detail the development of PN10, a highly potent and selective "hybrid" RIPK1 inhibitor, capturing the best properties of two different allosteric RIPK1 inhibitors, ponatinib and necrostatin-1. ponatinib receptor interacting serine/threonine kinase 1 Homo sapiens
