Cullgen公开TYK2降解剂专利《Tyrosine kinase 2 (TYK2) degradation compounds and methods of use》

 近日,Cullgen公开专利一项TYK2-PROTAC降解剂的专利《 Tyrosine kinase 2 (TYK2) degradation compounds and methods of use 》,该专利申请于2020年11月,TYK2靶蛋白配体连接VHL和CRBN配体。该靶点已由BMS验证在PsO适应症的疗效,并于2021年11月向FDA提交上市申请,除此适应症外,BMS的Deucravacitinib还在PsA(Ph3)、SLE(Ph2) 以及UC(Ph2 failed)等领域拓展。 以下是部分实施例结构以及在MOLT-4, NOMO-1 or Jurkat cells降解活性,那么Cullgen会在什么适应症尝试呢? Cullgen实施例内容 ” The preferred benefit to risk ratio of targeting TYK2 has increasingly attracted the interests of academia and pharmaceutical industry. Neutralizing antibodies against IL-12 and IL-23, the main cytokines that signal through TYK2, have been approved for treating psoriasis, psoriatic arthritis and Crohn’s disease. Over the past decade, a variety of TYK2 kinase inhibitors with varying degree of selectivity over other JAK family members have been reported and patented. Some of these TYK2 inhibitors have proceeded into different clinical stages. While TYK2 and other JAK kinase inhibitors hold promises treating a wide range of immunologic and malignant condi...

正大天晴启动IKZF1/3降解剂TQB3820临床研究(已终止)

 近日, 正大天晴 公示启动《 TQB3820 片治疗恶性血液肿瘤的I期临床试验》(NCT05020639/CTR20211930),TQB3820可降解 Aiolos和Ikaros 。本试验目的为评估TQB3820片在复发或难治性多发性骨髓瘤、惰性B细胞非霍奇金淋巴瘤受试者中的安全性和耐受性。 临床试验申请:2021.4.19 临床试验公示:2021.8.5( CTR20211930 )/2021.8.25( NCT05020639 ) 临床试验主动终止:2023.10.18(未达预期疗效) 根据专利检索结果可见正大天晴与 明德新药 联合申请CRBN蛋白相关疾病治疗药物的专利。 关于TQB3820 TQB3820 is a novel cereblon-modulating agent. Upon binding to cereblon, a substrate receptor in the cullin4 E3 ligase complex, TQB3820 promotes recruitment, ubiquitination, and subsequent proteasomal degradation of the hematopoietic transcription factors Ikaros (IKZF1) and Aiolos (IKZF3). Modulation of Aiolos and Ikaros expression has the potential to correct multiple aspects of the immune dysregulation mediated by B cells. 附国内企业公开在研的分子胶降解剂(竞争激烈程度俨然已经超出可以控制的范围): 康朴生物 的分子胶KPG-818(1期三年不见结果)和KPG-121(1期三年不见结果); 诺诚健华 的分子胶ICP-490(1/2期); 恒瑞医药 新一代分子胶HRS-3738(1期); 标新生物 分子胶GT919(1期)和GT929; 格博生物 在研分子胶GLB-001和GLB-002; 分迪药业 的分子胶FD-001。
