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。

Selective, high affinity, non-competitive α1A adrenoceptor antagonist (Ki = 0.35 nM). Exhibits no significant activity against a range of other GPCRs, including α2A, β1 and β2 adrenoceptors. Antagonizes effects of phenylephrine on isolated rabbit prostate muscle in vitro and on intra-urethral pressure in rats.

Camellianin A has anticancer activity, it can inhibit the proliferation of the human hepatocellular liver carcinoma Hep G2 and human breast adenocarcinoma MCF-7 cell lines in a dose-dependent manner and induce the significant increase of the G0/G1 cell population.
