Definitions
- the present invention relates to general formula (I)
- a prophylactic and therapeutic agent for thrombocytopenia comprising a muramyl-peptide A derivative represented by the formula:
- X is an amino acid residue selected from L-alanine, L-serine and L-pa, and R is Y, and Y is
- A represents a car ⁇ xyl group
- n represents an integer of 1 to ⁇
- ⁇ represents a 20 saturated aliphatic hydrocarbon residue which may have a molecule of 7 to 29 carbon atoms
- Acy 1 means an acyl group having 2 to ⁇ carbon atoms.
- pluripotent stem cells In the bone marrow of higher animals such as humans, there are granulocytes, monocytes (macrophages), 25 red blood cells, platelets, and lymphocytes called pluripotent stem cells. Blood cells such as spheres Differentiating stem cells These stem cells produce progenitor cells that differentiate into hematopoietic cells, and the progenitor cells produce blood cells in the next step. It is said that a specific growth factor is involved in this blood cell gun. For example, interlipticin-5 acts on pluripotent stem cells and promotes differentiation into granulocyte progenitor cells, and these progenitor cells contain granulocyte growth factor (such as G-CSF). It acts and granulocytes proliferate and mature. Platelets have been described as involving megakaryocytes, progenitor cells, and platelet growth factor (MK-CSF), but the details are still unclear. Wow.
- MK-CSF platelet growth factor
- platelets also have a great effect on the maintenance of human health independently of other blood cells or through mutual effects. That is, if the production of an appropriate platelet count is inhibited due to some abnormality in a living body or the like, a disease based on the decrease in platelets appears.
- thrombocytopenia symptomatic thrombocytopenia and idiopathic thrombocytopenia due to drugs (such as anticancer drugs), radiation, and blood diseases.
- Symptoms include bleeding and abnormal blood coagulation.
- the target compound of the present invention has excellent activity, It is disclosed in Japanese Patent Publication No. 02-27Q79, filed by the applicant of the present invention, as having an effect of preventing and treating microbial infection. However, whether or not the compound has an effect on the prevention and treatment of thrombocytopenia has not been known at all.
- the present inventors have conducted intensive studies on the compound of the formula (I), and as a result, have found that the compound exhibits an excellent effect on prevention and treatment of thrombocytopenia, and completed the present invention. That is, the present invention relates to a prophylactic and / or therapeutic agent for thrombocytopenia, comprising the compound of the formula (U) as an active ingredient.
- Examples of the dosage form of the preparation for administering the compound of the general formula U) include tablets, capsules, powders, granules, injections, suppositories, sprays, and external preparations.
- the formulation is excipients such as corn starch, lactose, and mannitol. Nore Senore Mouth, E. Li—Hi Binders such as loliton, low-substituted hydroxy: Manufactured according to known formulation technology using appropriate additives such as disintegrants such as labile cellulose and crystalline cellulose, lubricating agents such as talc and magnesium stearate. can do.
- the medicament of the present invention can be made into a sustained-release preparation by using a known sustained-release technique, if necessary.
- the thus-prepared medicament of the present invention is administered in a parenteral or parenteral manner, and its dosage is usually in the range of 1 QD to 40 Qg Z days per adult in the case of subcutaneous administration.
- conventional small blood If a whole blood transfusion or platelet transfusion, which is a typical treatment for platelet reduction, is used in combination with the medicament of the present invention, a more favorable therapeutic effect can be expected.
- the target compound of the present invention has low toxicity.
- LD 5 of the representative compound A described below [ 0 D 0 when subcutaneously administered to a rat]
- Example 1
- Example 2 Injection distilled water 1 n A freeze-dried injection containing 200 was obtained according to a known method using the above-mentioned formulation, and was dissolved at the time of use with the attached dissolution solution to prepare a preparation to be used.
- Example 2
- Compound A20 is a malignant lysoha. For 0 patients with tumors,
- the compound of the general formula U has an excellent preventive and therapeutic effect on thrombocytopenia, and is therefore excellent as an agent for preventing and treating thrombocytopenia.
