UC2288是一种新型的、具有细胞通透性和口服活性的p21衰减试剂(对p21具有相对选择性活性)，基于索拉非尼的结构合成。UC2288在不依赖p53的情况下下调p21mRNA的表达，降低p21蛋白水平，对p21蛋白的稳定性影响很小。UC2288对VEGFR2和Raf激酶没有抑制作用，即使在10μM。

Background:

UC2288 is a novel, cell-permeable, and orally active p21 attenuator (relatively selective activity for p21), which is synthesized based Sorafenib . UC2288 decreases p21 mRNA expression independently of p53, and attenuates p21 protein levels with minimal effect on p21 protein stability. UC2288 has no inhibition of VEGFR2 and Raf kinases even at 10 μM[1].

UC2288 (0-10 μM; 24 hours) decreases p21 protein level, but has no effects on other proteins[1].UC2288 (0-10 μM; 24 hours) decreases p21 mRNA expression transcriptionally or post-transcriptionally but independently of p53[1]. Western Blot Analysis[1] Cell Line: HK2 (normal kidney), 786-O (RCC), Caki-1 (RCC), ACHN (RCC) and HEY (ovarian cancer) cells

UC2888 (oral gavage; 15 mg/kg; 3 times a week; 4 weeks) co-treatment with imetelstat significantly suppresses tumor growth and does not effect mice weight[2].UC2288 (intraperitoneal injection; 10 mg/kg; 4 times in 7 days) attenuates MPTP-induced behavioral impairment, prevents activation of MAPK pathway in the MPTP-treated mice brain. MPTP treatment raises TNF-α, IL-6 and IL-1β levels in MPTP treated mice brain, but UC2288 signicantly decreases MPTP-induced TNF-α, IL-6 levels, but IL-1β is not decreased in brain[3]. Animal Model: Eight-week old, athymic nude (NCr nu/nu) mice injected subcutaneously with HCT116 and ACHN cancer cells(2.5x106)[2]
