产品介绍

Antitumor agent-81 (化合物 5 a) 是一种低细胞毒性的P62-RNF168激动剂，能促进P62与RNF168的相互作用。Antitumor agent-81 诱导RNF168介导的H2A泛素化减少，并损害同源重组介导的 DNA 修复。Antitumor agent-81 还能以剂量依赖的方式抑制小鼠异种移植肿瘤的生长。

生物活性

Antitumor agent-81 (compound 5a) is a low cytotoxicP62-RNF168agonist that promotes the interaction ofP62withRNF168. Antitumor agent-81 induces a decrease inRNF168-mediatedH2Aubiquitination and impairs homologous recombination-mediated DNA repair. Antitumor agent-81 also inhibits mice xenograft tumor growth in a dose-dependent manner^[1].

体外研究
(In Vitro)

Antitumor agent-81 (0-20 μM; 72 h) exhibits antiproliferative activity in cells of the most common cancer types^[1].
Antitumor agent-81 (1, 2, 5 μM; 24 h) compromises HR (homologous recombination)-mediated DSB repair in HCT-116 cells^[1].
Antitumor agent-81 tethers the interaction between P62 and RNF168 in HCT-116 cells^[1].
Antitumor agent-81 inhibits the catalytic activity of RNF168 and RNF168 E3 ligase activity in HCT-116 cells^[1].

Cell Proliferation Assay^[1]

Cell Line:	A549, HCT-116, A375, HeLa, HepG2, MCF-7, MDA-MB-231, MGC-803, U2OS and MCF-10A cells
Concentration:	0-20 μM
Incubation Time:	72 h
Result:	Inhibited A549, HCT-116, A375, HeLa, HepG2, MCF-7, MDA-MB-231, MGC-803, U2OS and MCF-10A cells, with IC₅₀values of 1.18, 0.36, 1.93, 2.48, 19.61, 2.79, 1.17, 1.88, 3.64 and 6.98, respectively.

Cell Cycle Analysis^[1]

Cell Line:	HCT-116 cells
Concentration:	1, 2, 5 μM
Incubation Time:	24 h
Result:	Induced a G2/M arrest but no significant accumulation of sub-G1 phase. Compromised both HR(homologous recombination)- and NHEJ (non-homologous end joining)- mediated DSB repair in a dose-dependent manner, but HR was the more severely impacted process.
