  • Patent number: 10858321
    Abstract: The present invention relates to a composition for inducing cell reprogramming. The indazole derivative compound contained in the composition of the present invention shows an improved biological profile and at the same time can perform efficient cell reprogramming. In addition, unlike conventional compounds (e.g. riversine or BIO) for inducing low-molecular cell reprogramming, the indazole derivative compound of the present invention does not show cytotoxicity and thus is expected to have high growth in the market of cell therapy products when clinically applied. Conventional indazole derivative compounds have never known as a use for cell reprogramming. Compared with conventional indazole derivative compounds, the compound of the present invention has a great cell reprogramming ability while having no or little cytotoxicity.
