Exploring the Binding of Calothrixin A to the G-Quadruplex from the c-myc Oncogene Promotor
Calothrixin A, a bioactive pentacyclic metabolite from the cyanobacteria Calothrix, has potent antiproliferative behaviour against several cancer cell lines. The in vitro binding of calothrixin A to the DNA quadruplex formed at the promotor region of c-myc was investigated by monitoring changes in the fluorescence emission of 2-aminopurine (2Ap)-substituted analogues of the native Pu22 sequence d(TGAGGGTGGGGAGGGTGGGGAA) on titration with calothrixin A and N-methoxymethyl-calothrixin B....[Show more]
