Patent number: 10208097Abstract: The present invention relates to a saxatilin derivative having an increased half life and a use thereof. The saxatilin derivative of the present invention has thrombolytic ability similar to that of saxatilin, which is the mother protein, a remarkably increased protein half life, and efficiently dissolves, for long period of time, blood clots already formed in blood vessels of an animal model with a FeCl3-induced carotid by using the same. Therefore, a composition containing, as an active ingredient, the saxatilin derivative of the present invention does not cause reocclusion after penetration and effectively opens to microvessels, and is thus very useful for treating angiostenosis or occlusive diseases (for example, cerebrovascular diseases, cardiovascular diseases, arteriosclerotic vascular diseases, coronary artery diseases, and peripheral vascular diseases).Type: GrantFiled: August 8, 2017Date of Patent: February 19, 2019Assignee: INDUSTRY-ACADEMIC COOPERATION FOUNDATION, YONSEI UNIVERSITYInventors: Sung Yu Hong, Ji Hoe Heo, Il Kwon, Dong Ik Kim, Yang Soo Jang, Young Dae Kim

Patent number: 9982021Abstract: The present invention relates to: a composition for dissolving thrombi comprising a peptide comprising the Arg-Gly-Asp motif; a pharmaceutical composition for treating stenotic or occlusive vascular diseases which comprises the same; and a thrombus dissolving method and a method for treating stenotic or occlusive vascular diseases, comprising the step of administering the same. The compositions and methods of the present invention have the advantage that they effectively break down already formed thrombi by adopting the principle of targeting integrin within the thrombus such as platelet surface GPIIb-IIIa, which is not the same as the existing principle of plasminogen activation. Also, the compositions and methods of the present invention have a nerve-protecting function as they effectively open as far as the microvasculature, without the occurrence of restenosis after penetration.Type: GrantFiled: November 1, 2011Date of Patent: May 29, 2018Assignee: INDUSTRY-ACADEMIC COOPERATION FOUNDATION, YONSEI UNIVERSITYInventors: Ji Hoe Heo, Il Kwon, Young Dae Kim, Sung Yu Hong

Patent number: 8377676Abstract: The present invention relates to a batroxobin-encoding nucleotide sequence and/or a mutated ?-factor secretion signal sequence, and a vector and a transformant using the same. The batroxobin-encoding nucleotide sequence of this invention exhibits an excellent expression efficiency in yeast, particular Pichia pastoris and the recombinant batroxobin is obtained at 4-13 fold higher yield than natural-occurring batroxobin-encoding sequences. The protein expression system which uses the batroxobin-encoding nucleotide sequence as well as mutated ?-factor secretion signal peptide sequence of this invention obtains the recombinant batroxobin at about 20-fold higher yield than natural-occurring batroxobin-encoding sequences. In addition, the recombinant batroxobin prepared using the sequence of this invention has a significantly plausible activity and stability compared with natural-occurring batroxobin.Type: GrantFiled: December 23, 2008Date of Patent: February 19, 2013Assignee: Biobud Co., LtdInventors: Young-Doug Sohn, Bum Joon Kim, Ok Hwan Kim, Kyoung Jun Kim, Ji Hun Shin, Sung Yu Hong, Jae Hoon Hwang, Kwang Hoe Chung
