Patent number: 11926618Abstract: A compound of formula (I) or an optical isomer thereof, and pharmaceutically acceptable salts, prodrugs, aquo-complexes or non-aqueous-solvent complexes thereof are provided. Experiments prove that, compared with a control compound MGL-3196, the compound of formula (I), which is obtained through specific substitution sites and specific substitution types, is higher in agonist activity to THR-beta and significantly improved in selectivity on THR-beta/THR-alpha. The compound can be used in preparing THR-beta agonist and drugs for treating adaption diseases (including dyslipidemia, hypercholesteremia, non-alcoholic steatohepatitis and non-alcoholic fatty liver disease) applicable to the THR-beta agonist.Type: GrantFiled: August 20, 2020Date of Patent: March 12, 2024Assignee: HINOVA PHARMACEUTICALS INC.Inventors: Wu Du, Yu Li, Haibo Li, Yuanwei Chen, Chengzhi Zhang, Xinghai Li

Patent number: 11622084Abstract: A hyperspectral camera based on a continuously variable film filter and a coating method thereof can solve interference between partial bands of the hyperspectral camera based on the continuously variable film filter. The hyperspectral camera includes: a camera body and a detector chip, wherein a continuously variable film is coated on the detector chip; a semi-transmission half-cut filter is provided in front of the continuously variable film, and a distance between the semi-transmission half-cut filter and the continuously variable film is 0 mm. According to the present invention, the semi-transparent half-cut filter and the detector chip are integrated without any gap therebetween. As a result, optical interference caused by incident light sequentially passing through the semi-transparent half-cut filter and the detector chip is greatly reduced, which can reduce distortion of spectral signals, and finally satisfy wide-band application requirements which can be truly realized based on such technology.Type: GrantFiled: June 29, 2020Date of Patent: April 4, 2023Assignee: Jiangsu Dualix Spectral Imaging Technology Co., LtdInventors: Xinghai Chen, Yelin Liu, Zhihui Huang, Hongyu Zhang, Yu Huang
