Provided are applications of spermine and derivatives thereof. On the basis of existing protein structure data and small molecule structure data, calculations and analysis are performed using software to screen and obtain compounds capable of effectively interfering with PAICS activity, reducing SAICAR synthesis, and ultimately reducing SAICAR accumulation, in order to achieve the goal of treating or reducing ADSL deficiency. A better effect in the treatment or improvement of ADSL deficiency is expected from the joint use of at least two of the described compounds.
