一般說明
一种可逆、细胞可渗透吡唑啉酮p300/CBP HAT抑制剂（Ki = 400 nM），可与乙酰辅酶A竞争p300 Lys-CoA结合袋。该化合物在10 nM处对p300有86%的抑制作用，但在化学筛选测定中对羟色胺N-乙酰转移酶、PCAF组蛋白乙酰转移酶、GCN5组蛋白乙酰转移酶、Rtt109组蛋白乙酰转移酶、Sas组蛋白乙酰转移酶以及MOZ组蛋白乙酰转移酶的抑制作用均小于10%。使用25µ M化合物处理C3H 10T1/2小鼠成纤维细胞可对组蛋白H3和H4的基础和TSA诱导乙酰化产生抑制效果。研究还表明，与25 µM基于多肽双底物p300/CBP HAT抑制剂Lys-CoA-Tat相比，10µM时可抑制黑色素瘤和非小细胞肺（NSCL）癌细胞系中人类细胞生长，并且具有相似或更高的药效。

Tumor suppressor p53, a critical regulator of cell fate, is frequently mutated in cancer. Mutation of p53 abolishes its tumor-suppressing functions or endows oncogenic functions. We recently found that p53 binds via its proline-rich domain to peptidase D (PEPD) and

Development can be altered to match phenotypes with the environment, and the genetic mechanisms that direct such alternative phenotypes are beginning to be elucidated. Yet, the rules that govern environmental sensitivity vs. invariant development, and potential epigenetic memory, remain unknown.
