Trabectedin D3 (Synonyms: Ecteinascidin 743 D3; ET-743 D3)

Trabectedin D3 (Ecteinascidin 743 D3) 是 Trabectedin 的氘代物。Trabectedin (Ecteinascidin 743; ET-743) 是一种四氢异喹啉生物碱,具有有效的抗肿瘤活性。Trabectedin 与 DNA 的小沟结合,阻断应激诱导的蛋白质的转录,诱导 DNA 骨架裂解和癌细胞凋亡 (apoptosis),并增加 MCF-7 和 MDA-MB-453 细胞中 ROS 的生成。Trabectedin 可用于软组织肉瘤和卵巢癌的研究。

Trabectedin D3 (Ecteinascidin 743 D3) is deuterium labeled Trabectedin. Trabectedin is a tetrahydroisoquinoline alkaloid with potent antitumor activity. Trabectedin binds to the minor groove of DNA, blocks transcription of stress-induced proteins, induces DNA backbone cleavage and cancer cells apoptosis, and increases the generation of ROS in MCF-7 and MDA-MB-453 cells. Trabectedin has tje potential for soft tissue sarcoma and ovarian cancer treatment[1][2][3].
