  • Patent number: 11926618
    Abstract: 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.

  • Publication number: 20230117633
    Abstract: A method for predicting a node state, including: obtaining static graphs and dynamic graphs of a plurality of nodes in a target network, where the static graphs and the dynamic graphs are all topology views; generating spatial feature data of the plurality of nodes based on the static graphs and the dynamic graphs; obtaining time feature data of the plurality of nodes; and obtaining a predicted state of a target node in a target time range based on the spatial feature data and the time feature data, where the target node is any node in the plurality of nodes. The method for predicting a node state provided in this application is applied to the field of node state prediction in a network, and uses a dynamic spatial feature in addition to a time feature and a static spatial feature.

  • Publication number: 20220257774
    Abstract: An aromatic amine androgen receptor (AR) and BET targeting protein degradation chimera compound is represented by formula I. Experimental results show that the compound can target and degrade both AR and BRD4, and down-regulate the expression of AR and BRD4 proteins; the compound can inhibit the proliferation of a variety of prostate cancer cells; the compound can inhibit the proliferation of a prostate cancer cell line LNCaP/AR, which overexpresses the AR, and can achieve a good inhibition effect on a prostate cancer cell line 22RV1, which is resistant to a marketed prostate cancer drug (enzalutamide). The compound also shows good metabolic stability, and has a good application prospect in the preparation of an AR and/or BET protein degradation targeting chimera, and a drug for the treatment of related diseases regulated by the AR and BET.
