MSA-2
产品介绍 | MSA-2 是一种口服非核苷酸 STING 激动剂,以具有纳摩尔亲和力的非共价二聚体形式与 STING 结合。MSA-2 对人的 STING 亚型 WT 和 HAQ 的 EC50 分别为 8.3 和 24 μM。MSA-2 在同基因小鼠肿瘤模型中显示抗肿瘤活性,刺激肿瘤分泌干扰素-β,诱导肿瘤消退,具有持久的抗肿瘤免疫,并与抗 PD-1 协同作用。 | ||||||||||||||||

生物活性 | MSA-2, a potent and orally available non-nucleotide STING agonist, is bound to STING as a noncovalent dimer with nanomolar affinity. MSA-2 shows EC50s of 8.3 and 24 μM for human STING isoforms WT and HAQ, respectively. MSA-2 stimulates interferon-β secretion in tumors, induces tumor regression with durable antitumor immunity, and synergizes with anti-PD-1 in syngeneic mouse tumor models. | ||||||||||||||||

体内研究 |
MSA-2 dosed via either PO or SC regimens achieved comparable exposure in both tumor and plasma. MSA-2 also exhibits dose-dependent antitumor activity when administered by IT, SC, or PO routes, and dosing regimens were identified that induced complete tumor regressions in 80 to 100% of treated animals. 西域 has not independently confirmed the accuracy of these methods. They are for reference only.
