Patent number: 11571460Abstract: The present invention relates to a composition including melittin as an active ingredient for removing an M2-type tumor-associated macrophage (TAM), and more specifically, the present invention relates to a composition exhibiting an effect of selectively suppressing only M2-type tumor-associated macrophages among tumor-associated macrophages. The composition according to the present invention only suppresses M2-type tumor-associated macrophages without affecting M1-type tumor-associated macrophages or cancer cells, thus exhibiting anti-cancer and metastasis suppressing effects by blocking angiogenesis through control of the microenvironment of cancer cells, while reducing the side-effects of existing anti-cancer effects.Type: GrantFiled: April 30, 2018Date of Patent: February 7, 2023Assignee: LENUS LABInventors: Hyunsu Bae, Chan-Ju Lee

Patent number: 11484601Abstract: The present invention relates to a melittin-anticancer drug conjugate in which melittin and an anticancer drug are conjugated, and to a method of preparing a melittin-anticancer drug conjugate by connecting melittin and an anticancer drug. A conjugate of the present invention is an anticancer material for targeting M2-type tumor-associated macrophages (TAM) and exhibits an excellent effect of selectively selecting M2-type tumor-associated macrophages (TAM), and thus may be used for a use of drug delivery for targeting M2-type tumor-associated macrophages.Type: GrantFiled: May 7, 2019Date of Patent: November 1, 2022Assignee: TWINPIGBIOLAB INC.Inventors: Hyun-Su Bae, Chan-Ju Lee, Jin-Hyun Jeong, Do-Ha Lee, Jeong-Dong Kim

Publication number: 20220204939Abstract: The present invention relates to: a method for preparing a stem cell culture solution which contains growth factors and cytokines and is obtained by culturing, in a serum-free medium, mesenchymal stem cells cultured in a medium containing human platelet lysates (hPLs); and a cosmetic composition using the stem cell culture solution. When the method for preparing a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an hPL-containing medium is used, it is possible to obtain a mesenchymal stem cell culture solution which has a higher amount of cytokines and growth factors than that of a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an FBS-containing medium, and has excellent efficacy in the promotion of human dermal fibroblast proliferation, collagen synthesis, elastin synthesis, inhibition of melanin synthesis, and hair growth.Type: ApplicationFiled: April 27, 2020Publication date: June 30, 2022Applicant: SCM LIFESCIENCE CO., LTD.Inventors: Sun Uk SONG, Si Na KIM, Chan Ju LEE
