nutlin-3

Nutlin-3 是一种 MDM2 拮抗剂，抑制 MDM2-p53 相互作用 (Ki=90 nM)，并激活 p53。Nutlin-3 优先与 MDM2 的 p53 结合口袋结合，导致 p53 的稳定和 p53 通路的激活。Nutlin-3 具有抗肿瘤活性。

(Rac)-Nutlin-3 在生命科学相关研究中具有广泛的应用。

Nutlin-3a 是 Nutlin-3 的活性对映体，是一种 MDM2 拮抗剂，抑制 MDM2-p53 相互作用 (Ki=90 nM)，并激活 p53。Nutlin-3a 优先与 MDM2 的 p53 结合口袋结合，导致 p53 的稳定和 p53 通路的激活。Nutlin-3a 具有抗肿瘤活性。

RITA (NSC-652287) 是 p53-HDM-2相互作用抑制剂，可诱导 DNA-DNA 和 DNA-蛋白质的交联，可与 p53dN 结合，Kd 值为 1.5 nM。

Nutlin-3 is an activator of p53 that functions by inhibiting the interaction of p53 with MDM2, a negative regulator of p53 activity. Caylin-1 is a nutlin-3 analog which contains chlorine substituents at the 3 and 4 positions on two of the phenyl rings rather than a single 4-chloro as seen in nutlin-3. At high concentrations, caylin-1 inhibits the growth of HCT116 cells with an IC50 value of approximately 7 μM, making it about 7-fold less potent than nutlin-3 in the same assay. Interestingly, at concentrations at or below 1 μM, caylin-1 promotes the growth of HCT116 cells approximately 20% compared to untreated cells. The mechanism of the growth promoting properties of caylin-1 have not yet been elucidated.

(±)-Nutlin-3 blocks the interaction of p53 with its negative regulator Mdm2 (IC50 = 90 nM), inducing the expression of p53-regulated genes and blocking the growth of tumor xenografts in vivo. CAY10682 is a pyrrolo[3,4c]pyrazole derivative that inhibits the p53-Mdm2 interaction as potently as (±)-nutlin-3 (Ki = 83 nM) and also dose-dependently reduces activation of the NF-κB pathway. It specifically prevents phosphorylation of IκBα by the kinases IKKα, IKKβ, and IKK (IC50s = 80.5, 78.2, and 57.1 μM, respectively). CAY10682 blocks the growth of cancer cells in vitro (IC50s = 2-6 μM) and inhibits the growth of A549 cell xenografts in mice without significantly reducing body weight.

Nutlin-C1-amido-PEG4-C2-N3 is a novel compound that functions as a ligand-linker conjugate for the E3 ligase. It is a synthesized molecule incorporating the MDM2 ligand derived from Nutlin 3, and a 4-unit PEG linker. This compound is specifically designed for utilization in PROTAC technology.

Nutlin-3b ((+)-Nutlin-3) 是一种 p53 MDM2 拮抗剂或抑制剂，IC50为 13.6 μM。它与 MDM2 的结合活性比 Nutlin-3a 低 150 倍。

Nutlin Carboxylic Acid (MDM2 ligand 1), derived from Nutlin 3, serves as an MDM2 ligand. It can be attached to a protein ligand via a linker to create PROTACs[1].

Nutlin-3 is an activator of p53 that functions by inhibiting the interaction of p53 with MDM2, a negative regulator of p53 activity. Caylin-2 is a nutlin-3 analog in which trifluoromethyl groups have been substituted for chlorine on the 2 phenyl rings. At high concentrations, caylin-2 inhibits the growth of HCT116 cells with an IC50 of approximately 8 μM, making it about 10-fold less potent than nutlin-3. Interestingly, at concentrations between 5-100 nM, caylin-2 promotes the growth of HCT116 cells approximately 40% compared to untreated cells. The mechanism of the growth promoting properties of caylin-2 have not yet been elucidated.

(4R,5S)-Nutlin Carboxylic Acid (MDM2 Ligand 2), a Nutlin 3-based MDM2 ligand, can be conjugated to a protein-binding ligand via a linker to create PROTACs[1].
