2wxv Summary



The structure was published by Traquandi, G., Ciomei, M., Ballinari, D., et al., Roussel, P., Vulpetti, A., and Brasca, M.G., in 2010 in a paper entitled "Identification of Potent Pyrazolo[4,3-H]Quinazoline-3-Carboxamides as Multi-Cyclin-Dependent Kinase Inhibitors." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2009.

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