A DNA-multiple drug complex, d(ACGTAGCTACGT)(2):[actinomycin D, (echinomycin)(2)] has been crystallized. The crystals belong to the monoclinic space group C2, with unit-cell parameters a = 85.6, b = 72.8, c = 56.6 A, beta = 101.5 degrees at 93 K and Z = 8. The crystal diffracted to 3.0 A resolution along the DNA fiber axis and to 3.5 A resolution in other(More)
Natural analogues (D, C2, and VII) of actinomycin inhibit Grb2 SH2 domain binding with phosphopeptide-derived from Shc in vitro and in intracellular system. To study structure-activity relationships, 13 actinomycin analogues were synthesized and we found that the inhibition activity depended on the substituents of cyclic peptide groups in actinomycin and(More)
