P-536 is a ACE inhibitor that also inhibits herpes simplex virus HSV-1 thymidine kinase and Trypanosoma cruzi RNA polymerase. By inhibiting the renin-angiotensin system, downregulating the expression of AT1R and NOX4, and reducing oxidative stress (decreasing plasma hydrogen peroxide (H2O2) and 8-isoprostaglandin levels), P-536 effectively reduces systolic blood pressure and improves vascular reactivity. P-536 also inhibits the replication of DNA/RNA viruses such as HSV-1 by blocking nucleotide metabolism and nucleic acid synthesis, competitively inhibits RNA synthesis in Trypanosoma cruzi, and inhibits amastigote replication, thereby impeding its growth. P-536 is suitable for research on hypertension, insulin resistance, and Chagas disease[1][2][3][4].
