Safety of 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amineOn November 30, 2011 ,《Comprehensive assay of kinase catalytic activity reveals features of kinase inhibitor selectivity》 appeared in Nature Biotechnology. The author of the article were Anastassiadis, Theonie; Deacon, Sean W.; Devarajan, Karthik; Ma, Haiching; Peterson, Jeffrey R.. The article conveys some information:

Small-mol. protein kinase inhibitors are widely used to elucidate cellular signaling pathways and are promising therapeutic agents. Owing to evolutionary conservation of the ATP-binding site, most kinase inhibitors that target this site promiscuously inhibit multiple kinases. Interpretation of experiments that use these compounds is confounded by a lack of data on the comprehensive kinase selectivity of most inhibitors. Here we used functional assays to profile the activity of 178 com. available kinase inhibitors against a panel of 300 recombinant protein kinases. Quant. anal. revealed complex and often unexpected interactions between protein kinases and kinase inhibitors, with a wide spectrum of promiscuity. Many off-target interactions occur with seemingly unrelated kinases, revealing how large-scale profiling can identify multitargeted inhibitors of specific, diverse kinases. The results have implications for drug development and provide a resource for selecting compounds to elucidate kinase function and for interpreting the results of experiments involving kinase inhibitors. In addition to this study using 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine, there are many other studies that have used 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine(cas: 213743-31-8Safety of 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine) was used in this study.

Application In Synthesis of 5-Bromo-4,6-dihydroxypyrimidineOn November 1, 1989 ,《Inhibition of uridine phosphorylase from Giardia lamblia by pyrimidine analogs》 appeared in Biochemical Pharmacology. The author of the article were Jimenez, Barbara M.; Kranz, Peter; Lee, Choy Soong; Gero, Annette M.; O’Sullivan, William J.. The article conveys some information:

Fifty-six pyrimidine analogs were tested as possible inhibitors of uridine phosphorylase from G. lamblia. Values of Ki were determined for eight of these which demonstrated an inhibition >60% under the standard conditions of uridine at 1 mM (approx. 1.5 times the Km) and inhibitor at 1 mM. All were competitive with respect to uridine. The most effective inhibitors were uracil analogs substituted at the C-5 position with electron-withdrawing groups (nitro groups or halogens). The inhibitory effect at the 5-position appeared to be further enhanced by substitution at the C-6 position with electron-releasing groups. The order of effectiveness as inhibitors was 6-methyl-5-nitrouracil > 6-amino-5-nitrouracil > 5-benzylacyclouridine > 5-nitrouracil > 5-fluorouracil > 5-bromouracil > 6-benzyl-2-thiouracil > 1,3-dimethyluracil, with Ki values of 10, 12, 44, 56, 119, 230, 190 and >1000 μM, resp. The compounds were also effective inhibitors of the thymidine phosphorylase activity of the enzyme. The results are discussed in relation to the use of these pyrimidine analogs to treat G. lamblia infections.
