spacer

JAK1 kinase (JH1 domain) in complex with the inhibitor (TRANS-4-{2-[(1R)-1-HYDROXYETHYL]IMIDAZO[4,5-D]PYRROLO[2,3-B]PYRIDIN-1(6H)-YL}CYCLOHEXYL)ACETONITRILE

The structure was published by Zak, M., Hurley, C.A., Ward, S.I., et al., Xiao, Y., Yang, J., and Kulagowski, J.J., in 2013 in a paper entitled "Identification of C-2 Hydroxyethyl Imidazopyrrolopyridines as Potent JAK1 Inhibitors with Favorable Physicochemical Properties and High Selectivity over JAK2." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.35 Å and deposited in 2013.

The experimental data on which the structure is based was also deposited.
