Abstract

The invention discloses a compound shown by formula I, or usage of salt or ester which can be acceptable thereby on pharmacology, namely, a composition used for preparing medicine that can control and treat leukocytopenia. The invention also discloses the usage on controlling and treating immunological suppression.

Description

technical field [0001] The invention belongs to the field of pharmacy, and more specifically, the invention relates to a compound with the effect of raising white blood cells and a new application of the composition thereof. Background technique [0002] The white blood cell count in human peripheral blood is continuously lower than the normal value (4x10 9 / L) is called leukopenia and is most commonly caused by neutropenia. Patients may be asymptomatic or have nonspecific symptoms such as fatigue, anorexia, decreased energy, and a predisposition to infection. Whether co-infected neutropenia decreased degree. The most common sites of infection are the lungs, urinary tract, and skin. Leukopenia can be divided into two types: hereditary and acquired, among which acquired is the majority. Drugs, radiation, infection, toxins, etc. can all reduce leukocytes, and drugs are the most common. During treatment, the cause of leukopenia should be carefully searched, and appropriate...
