Nurix Therapeutics专注于发现、开发和商业化口服小分子疗法，这些疗法旨在调节细胞蛋白水平，作为 癌症和免疫疾病的新型治疗方法。该公司的研发管线包括布鲁顿酪氨酸激酶(BTK)的靶向蛋白降解剂， 以及Casitas B细胞淋巴瘤原癌基因-B(CBL-B，一种调节T细胞活化的E3连接酶)的抑制剂。其蛋白降解 产品线中的候选药物NX-2127是一种口服可用的BTK降解剂，用于治疗复发或难治性B细胞恶性肿瘤。 资料显示，布鲁顿氏酪氨酸激酶(BTK)抑制剂是多种B细胞血液癌症的重要治疗选择。然而BTK抑制剂 耐药性的出现，以及BTK不依赖于激酶活性介导信号传导的功能，揭示了采用其它手段靶向BTK蛋白功 能的重要性。靶向BTK的蛋白降解剂通过直接诱导BTK蛋白被蛋白酶体降解，为克服BTK抑制剂耐药性 提供了有效策略。 值得一提的是，投行Needham在周一重申了对Nurix Therapeutics的"买入"评级，维持目标价为26美元。 该行分析师表示，对该公司市场前景的信心保持不变。在上个月，Truist首予Nurix Therapeutics"买入"评 级，目标价为30美元;BTIG则重申对Nurix ...

Core Viewpoint - The company has established a systematic layout in its new molecular business, focusing on four cutting-edge areas: ADC, TPD, and TIDES, and has developed comprehensive service capabilities from early research to process development and production [1] Group 1: ADC (Antibody-Drug Conjugates) - The company utilizes an artificial intelligence research platform to create end-to-end service capabilities, including innovative linker design, linker-payload synthesis, targeted coupling technology, and stability research, providing one-stop support from candidate molecules to clinical application [1] Group 2: TPD (Targeted Protein Degradation) - In the TPD area, the company has designed and supplied CRBN molecular building blocks and novel linkers during the research phase, and has established a one-stop CMC service platform to offer full-cycle services from early API and formulation development to mid-to-late stage optimization and commercial production [1] Group 3: TIDES - To address bottlenecks in traditional solid-phase synthesis for long peptides and large-scale production, the company has focused on developing core technologies such as liquid-phase synthesis, enzymatic synthesis, and continuous flow synthesis, creating an integrated solution centered on non-natural amino acids and peptide technology to meet diverse customer needs [1] Group 4: Business Growth and Future Outlook - Although the new molecular business is still in its early stages, accounting for less than 10% of total revenue, it shows strong growth momentum with order growth exceeding 100%. The company is confident in the future prospects of this business and plans to continue investing in technology and capacity building to drive it as an important growth engine [1]
