NAZ2329
目录号 : KM5906 纯度 : 98%

NAZ2329 是受体型蛋白质酪氨酸磷酸酶 (RPTPs) R5 亚家族的第一个细胞可渗透抑制剂,相对于其他 PTPs,它变构且优先抑制PTPRZ (hPTPRZ1 的 IC50 = 7.5 µM) 和 PTPRG (hPTPRG IC50 = 4.8 µM)。NAZ2329 与 PTPRZ 的 D1结构域结合,相对于 PTPRZ 整个 (D1 + D2) 片段,其更有效地抑制 PTPRZ1-D1片段,其 IC50 为1.1 µM。NAZ2329 可有效抑制胶质母细胞瘤细胞的肿瘤生长并抑制干细胞样特性。

生物活性

NAZ2329, the first cell-permeable inhibitor of R5 subfamily of receptor-type protein tyrosine phosphatases (RPTPs), allosterically and preferentially inhibits PTPRZ (IC50=7.5 µM for hPTPRZ1) and PTPRG (IC50=4.8 µM for hPTPRG) over other PTPs. NAZ2329 binds to the active D1 domain and more potently inhibits PTPRZ-D1 fragment (IC50 of 1.1 µM) than the whole intracellular (D1 + D2) fragment (IC50 of 7.5 µM). NAZ2329 can effectively inhibit tumor growth of the glioblastoma cells and suppress stem cell-like properties.

体外研究

NAZ2329 (0-25 µM; 48 hours) dose-dependently inhibits cell proliferation and migration in all cell lines (rat glioblastoma cells bearing C6 clone and human U251 glioblastoma cells) .
NAZ2329 (25 µM; 0-90 min) obviously promotes the phosphorylation level of paxillin at Tyr-118 site, leading to inhibition for PTPR substrate.

Cell Proliferation Assay

Cell Line: Rat glioblastoma cells bearing C6 clone, human U251 glioblastoma cells
Concentration: 0 µM, 6.3 µM, 12.5 µM, 25 µM
Incubation Time: 48 hours
Result: Exerted inhibition in cell proliferation and migration in a dose-dependent manner.

Western Blot Analysis

Cell Line: Rat glioblastoma cells bearing C6 clone
Concentration: 25 µM
Incubation Time: 0 min, 15 min, 30 min, 60 min, 90min
Result: Promoted the phosphorylation level of paxillin at Tyr-118 site.
体内研究

NAZ2329 (22.5 mg/kg; intraperitoneal injection; twice per week; 40 days) alone has a moderate inhibitory effect. However, the combination of Temozolomide and NAZ2329 exerts a significantly increased inhibition of tumor growth compared with the control group, the NAZ2329 monotherapy group and the Temozolomide monotherapy group.

Animal Model: Female BALB/c- nu/nu mice aged 4 week-old bearing parental or Ptprz-knockdown C6 cells
Dosage: 22.5 mg/kg; Temozolomide (TMZ, 50 mg/kg)
Administration: Intraperitoneal injection; twice per week; 40 days
Result: The combination of NAZ2329 and TMZ significantly delayed tumor growth compared to NAZ2329 or TMZ alone.
