Acetyl-β-Endorphin (human) 是一种多肽，能够由多肽筛选发现。多肽筛选是一种主要通过免疫测定法而集合活性多肽的研究工具。多肽筛选可用于蛋白互作、功能分析，抗原表位筛选，特别是活性分子研究和开发领域。

Heliotrine N-oxide is the pyrrolizidine alkaloid (PA) N-oxide counterpart of Heliotrine. It induces the generation of pyrrolic DNA adducts, potentially initiating PA-induced liver tumors in vivo.
