Chemical characterization and biological activity data for a novel indirubin derivative, LDD-1819

Abstract

This article contains chemical characterization and biological activity data for a novel indirubin derivative, termed LDD-1819. The detailed synthesis procedure and associated NMR data are presented. The concentration-dependent inhibition data of two biological targets, glycogen synthase kinase-3 and aurora kinase A are described. The following biological data are also contained in this article: 1) the cellularization of skeletal muscle myotubes by LDD-1819 or two small molecule inhibitors of glycogen synthase kinase-3 and aurora kinase A (BIO and reversine) and gene expression data for the myoblast markers Pax-7 and Myf5, 2) Cell viability of hTERT human immortalized fibroblasts, colon cancer cells and breast cancer cells, and 3) Western blotting analysis of full length and cleaved caspse-7, and cleaved poly (ADP-ribose) polymerase (PARP) in hTERT fibroblasts treated with LDD-1819. A schematic diagram of the biological activities of LDD-1819 is also presented. Further interpretation and discussion of these data are provided in the associated research article ‘A novel indirubin derivative that increases somatic cell plasticity and inhibits tumorigenicity’ (Kim et al., 2019).
