Optimization of 4,6-bis-anilino-1H-pyrrolo[2,3-d]pyrimidine IGF-1R tyrosine kinase inhibitors towards JNK selectivity.
S.D.Chamberlain, A.M.Redman, J.W.Wilson, F.Deanda, J.B.Shotwell, R.Gerding, H.Lei, B.Yang, K.L.Stevens, A.M.Hassell, L.M.Shewchuk, M.A.Leesnitzer, J.L.Smith, P.Sabbatini, C.Atkins, A.Groy, J.L.Rowand, R.Kumar, R.A.Mook, G.Moorthy, S.Patnaik.
The SAR of C5' functional groups with terminal basic amines at the C6 aniline of 4,6-bis-anilino-1H-pyrrolo[2,3-d]pyrimidines is reported. Examples demonstrate potent inhibition of IGF-1R with 1000-fold selectivity over JNK1 and 3 in enzymatic assays.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
