Abstract:
PURPOSE: An antibody-drug conjugate (ADC) is provided to show superior treatment effect compared with an existing conjugate because large drugs are conjugated to antibodies. CONSTITUTION: A lipoprotein variant is able to encapsulate a drug and has a hydrophilic region in which one or more amino acid residues are substituted with cysteine. The hydrophilic region is exposed to the outside of the lipoprotein when the drug is encapsulated. A nanostructure is prepared by encapsulating the drug in a three-dimensional structure of the variant lipoprotein. An ADC has lipoprotein and an antibody which are linked directly or by a linker and contains the drug encapsulated in the three-dimensional structure of isolated lipoprotein.

Abstract:
PURPOSE: A method for preparing an insoluble drug nanocomplex is provided to enhance manufacture yield of the insoluble drug nanocomplex. CONSTITUTION: A method for preparing an insoluble drug nanocomplex comprises: a step of dissolving insoluble drug in a solvent containing surfactant; a step of adding apolipoprotein in the solution; a step of heating the solution; and a step of removing surfactant and solvent from the solution. The insoluble drug is dissolved with phospholipid. The phospholipid is phosphatidylcholine. The insoluble drug is coenzyme Q10, ursodeoxycholic acid, ilaprazole, paclitaxel or imatinib mesylate. The surfactant is cholic acid or salt thereof. The apolipoprotein is apolipotprotein A-I.
Abstract:
PURPOSE: A method for fixing membrane protein on a solid surface is provided to widely screen membrane protein in chip-based array. CONSTITUTION: A method for fixing membrane protein on a solid surface comprises a step of collecting the membrane protein inside a membrane structure and a step of fixing the membrane protein on the solid surface. The membrane structure is formed by surrounding phospholipid by apolipoprotein A-1 which is elongated at N-terminal or C-terminal or both terminals. The solid is Ni-NTA and amino acid sequence is histidine sequence. The solid contains glutathione and the sequence of the amino acid is glutathione-S-transferase(GST). The amino acid sequence is bound to the apolipoprotein A-I by mediating peptide linker.
Abstract:
PURPOSE: A high intensity lipoprotein (HDL) - analogous particle combination is provided to be able to be widely used for the development of the drug specific target. CONSTITUTION: A high intensity lipoprotein (HDL) - analogous particle combination comprises apolipoprotein A- I (apoA-I) and drug, The drug which the pH is dependently sampled can be ejected. The apolipoprotein A- I (apoA-I) comprises the amino acid sequence of the sequence number 1. Drug comprises the ring structure. It is selected from group comprised of the drug is the paclitaxel, DX (doxorubicin), MTX (methotrexate), SF (Sorafenib) and EpoB (Epothilone B).
Abstract:
본 발명은 산성 pH 조건에서 내부에 포집된 약물을 방출할 수 있도록 아포리포단백질 AI(apoA-I)과 이에 포집된 약물을 포함하는 고밀도 리포단백질(HDL)-유사 입자 결합체 및 그의 제조방법에 관한 것이다. 본 발명의 고밀도 리포단백질(HDL)-유사 입자 결합체는 산성조건에서 포집된 약물을 배출할 수 있으면서도, 산성조건이 아닌 경우에는 온도가 넓은 범위로 변화될 경우에도 안정성을 나타내므로, 표적 특이적인 약물의 개발에 널리 활용될 수 있을 것이다.
