生物活性

PGD97 is a selective cyclic peptide inhibitor against CAL/CFTR interactions, with a KD value of 6 nM towards the CAL PDZ domain for its desulfide cyclized form. PGD97 (desulfide cyclized form) has selectivity ≥ 130-fold compared to NHERF1/2 PDZ domains. PGD97 is capable of stabilizing F508del-CFTR at the cell membrane and improving CFTR function required for proper fluid homeostasis in tne lung. PGD97 can be used for the research of cystic fibrosis[1].

体外研究
(In Vitro)

PGD97 (Compound 24c) 在 HeLa 细胞中显示出强的细胞进入效率 (相对于 CPP9 为 61) [1]
PGD97 (24 h,37 °C) 在人体血清中高度稳定,其中 ∼ 77% 的肽保持完整无损[1]
PGD97 (5 μM) 能有效进入 HCT116 细胞的细胞膜,并被细胞内的硫醇迅速还原成具有生物活性的线性形式 (24),随后在细胞膜内发生部分降解[1]
PGD97 (0-50 μM,72 h) 对细胞系 CFBE41o-、HCT116 和 H358 都无明显的细胞毒性[1]
PGD97 (100 nM) 可使患者来源的 F508del 基因同源细胞中的短路电流增加 ∼ 3 倍,并使小分子校正剂 (如 VX-661) 的治疗效果进一步增强 ∼2 倍 (∼ 10 nM 的 EC50)[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
