Synthesis and biological evaluation of 3,5-diaminoindazoles as cyclin-dependent kinase inhibitors.
J.Lee, H.Choi, K.H.Kim, S.Jeong, J.W.Park, C.S.Baek, S.H.Lee.
A novel series of 3,5-diaminoindazoles were prepared and found to be CDK inhibitors. Potent inhibitors against CDK1 and CDK2 were obtained by introduction of 1lambda(6)-isothiazolidine-1,1-dioxide at 5-position of indazole. Anti-proliferative activities of compounds were evaluated using EJ, HCT116, SW620, and A549 cancer cell lines.

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.
