The application belongs to the field of new use of drugs, and more particularly relates to application of 3-Deazaadenosine in preparation of a therapeutic
drug for treating
hypertrophic scars. 3-Deazaadenosine is an S-adenosylhomocysteine
hydrolase inhibitor, and has antiviral, anti-inflammatory and other activities. Experiments show that the compound can significantly reduce the modification level of m6A in fibroblasts in
hypertrophic scar tissue, inhibit the proliferation and migration of fibroblasts, promote the
apoptosis of fibroblasts, and also can reduce the expression levels of
Collagen I, Collagen III and alpha-SMA in fibroblasts. Therefore, the compound can be used for preparing a
drug for relieving or treating
hypertrophic scars, and has important clinical application value.
