摘要:
A synthesis method for pyrrole-imidazole polyamide is automated at a higher level and can produce a product with a high yield in a more stable manner. In a solid phase synthesis method, the automated synthesis of a polyimide can be promoted by using HCTU as a condensation-activator, the yield of a product can be increased by charging a monomer in a solid form, and a pyrrole-imidazole polyamide having any sequence can be synthesis by combining the synthesis method with a manual synthesis with an acid chloride.

摘要:
Provided is a ribozyme to cleave a coronavirus gene and a therapeutic agent for a coronavirus infectious disease. A common base sequence in coronaviruses such as SARS-CoV and MHV was searched to design a ribozyme including a base sequence complementary thereto. Moreover, a therapeutic agent for a coronavirus infectious disease including such ribozyme was obtained.

摘要:
To provide infusion therapy that can effectively transluminally deliver drugs or the like to a target spot without invading areas other than a diseased area. The infusion therapy is for administering a drug, cells or the like, or inserting a treatment instrument into the target diseased area. A blood vessel area including a bifurcated blood vessel connecting to the diseased area is occluded at the distal and the proximal region thereof to form an occluded area, and the drugs or the like are pumped and supplied to the occluded area, which causes the drugs or the like to flow retrogressively and retentively in the bifurcated blood vessel connecting in the occluded area, and be infused and administered to the diseased area.
