7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine(cas: 213743-31-8) belongs to pyrimidine. Pyrimidine nucleotide derivatives have a wide range of biological applications. For example, pyrimidine derivatives are useful in DNA repair studies involving cancer and epigenetics.Electric Literature of C23H22N4O

Electric Literature of C23H22N4OOn June 1, 2001, Banic Tomisic, Zrinka; Cempuh, Andreja; Malnar, Ivica published an article in Acta Crystallographica, Section E: Structure Reports Online. The article was 《7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidine-4-ylamine, a lck tyrosine kinase inhibitor》. The article mentions the following:

The mol. and crystal structures of the potent and selective lck tyrosine kinase inhibitor, C23H22N4O, were determined by single-crystal x-ray diffraction. The pyrrolopyrimidine and Ph rings are planar while the cyclopentyl ring adopts a conformation between envelope and half-chair. The overall conformation is defined by the spatial arrangement of the ring moieties. Crystallog. data are given. In the part of experimental materials, we found many familiar compounds, such as 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine(cas: 213743-31-8Electric Literature of C23H22N4O)
