Abstract

The invention provides application of a novel skeleton compound in preparing drug for preventing and treating parasitic infection disease. The novel skeleton compound can be used as calcium-dependent protein kinase. The invention discloses an isoindole-1, 3-diketone compound which has effect of inhibiting activity of the calcium-dependent protein kinase, can be used for preparing the drug for preventing or / and treating protozoal infectious disease and has potential application prospect in acute and chronic parasitic disease. Comparison tests show that the isoindole-1, 3-diketone compound has obvious higher activity in inhibiting CDPK1 than a pyrazolopyrimidine compound NM-PP1.

Description

technical field [0001] The invention relates to medical technology, in particular to a new application of isoindole-1,3-dione compound in medicine. Background technique [0002] Toxoplasma gondii, an intracellularly reproducing parasite, is one of the parasites with the widest range of host species. At present, Toxoplasma gondii infection has become one of the most common foodborne infectious diseases requiring hospitalization in the world, and the total number of infected people worldwide has exceeded 2 billion. Toxoplasma gondii infection is a fatal threat to immunocompromised people, such as organ transplantation, cancer or AIDS patients. In addition, toxoplasmosis can also cause abnormal development of human embryos and abortion. At present, the drugs for the treatment of toxoplasmosis are mainly broad-spectrum antibacterial compounds such as pyrimethamine and sulfadiazine, but such compounds are prone to drug resistance and side effects, resulting in a decline in long...
