Reprogramming Compound Library

3,086 compounds

Techniques for reprogramming somatic cells create new opportunities for drug screening, disease modeling, artificial organ development, and cell therapy. The development of reprogramming techniques has grown exponentially since Yamanaka reprogrammed somatic cells to become induced pluripotent stem cells (iPSCs) using four transcription factors, OCT4, SOX2, KLF4, and c-MYC in 2006. Despite the development of efficient reprogramming methods, most methods are inappropriate for clinical applications because they carry the risk of integrating exogenous genetic factors or use oncogenes. Alternative approaches, such as those based on miRNA, non-viral genes, non-integrative vectors, and small molecules, have been studied as possible solutions to the problems. Among these alternatives, small molecules are attractive options for clinical applications. Reprogramming using small molecules is inexpensive and easy to control in a concentration- and time-dependent manner. It offers a high level of cell permeability, ease of synthesis and standardization, and it is appropriate for mass-producing cells.

MCE Reprogramming Compound Library contains a unique collection of 3,086 compounds that act on reprogramming signaling pathways. These compounds are potential stimulators for reprogramming. This library is a useful tool for researching reprogramming and regenerative medicine.

Ultevursen sodium (QR-421a) is a splice-modulating antisense oligonucleotide targeting exon 13 of the USH2A gene, which restores the functional expression of Usherin protein by inducing exon skipping. Ultevursen sodium binds to USH2A pre-mRNA and modulates the splicing process to specifically skip exon 13 carrying the pathogenic mutation c.2299delG, generating an in-frame transcript and a truncated yet functionally normal protein. Ultevursen sodium exhibits concentration-dependent exon skipping activity in human cells and retinal organoid models, and restores Usherin expression and retinal function in zebrafish and gene-edited mouse models. Ultevursen sodium can be used for related research on type 2 Usher syndrome and non-syndromic retinitis pigmentosa .
