Abstract: Provided are compounds reducing SAICAR accumulation, and applications. 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 improving 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.

Abstract: The present invention discloses application of compounds in the preparation of reagents for down-regulation of Runx2. The inventors have confirmed through computational studies and disease models that Fostamatinib, Regorafenib and melatonin can significantly down-regulate the expression of Runx2, and have a significant targeted therapeutic effect on cancers with abnormally high expression of Runx2, and are efficient reagents for reducing the expression of Runx2. Especially the Runx2 expression down-regulation reagent used in the laboratory.

Abstract: Applications of spermine or its pharmaceutically acceptable derivative in preparation of an SAICAR synthetase activity interfering agent or inhibitor. Applications of spermine or its pharmaceutically acceptable derivative in preparation of antitumor drug.

Abstract: Disclosed are applications of spermidine or its pharmaceutically acceptable derivatives. The inventors performed calculation and analysis using software based on existing data relating to protein and small-molecule structures, and screened out compounds which can effectively interfere with the activity of PAWS and thus reduce SAICAR synthesis, thereby achieving the goal of treating or improving tumors. It is expected to produce better effect in the treatment or improvement of tumors.

Abstract: Disclosed is an application of allopurinol in the preparation of a drug for treating a cancer with high expression of a PAICS gene. Through screening by cell biology combined with animal experiments, and by bioinformatics analysis of gene expression of about 10,000 sample data from the TCGA database, It can be found and confirmed that allopurinol has significant anti-cancer and therapeutic effects on the cancer with abnormally high expression of the PAICS gene, including but not limited to, combined chemotherapy for cancer resistance, inhibition of cancer recurrence, improvement of prognosis survival rate, and the like.

Abstract: Disclosed is use of a YY-dipeptide in the manufacture a medicament or a healthcare product for lowering blood pressure. In the present disclosure, ACE inhibitory activities of dipeptides are virtually screened by means of a molecular docking method and a self-developed software, based on the determined crystal structure of ACE enzyme. The dipeptides obtained by the virtual screening were experimentally verified for the ACE inhibitory activity thereof. As a result, the YY-dipeptide is found to have relatively good ACE inhibitory activity. A peptide or protein composed of multiple tyrosine residues can be hydrolyzed into an active YY-peptide in vivo, and produce the same or a similar effect.
