生化/生理作用

DAPT是一种γ-分泌酶抑制剂，间接抑制Notch，即一种γ-分泌酶底物。其他的γ-分泌酶底物包括LDL受体相关蛋白、E-cadherin和ErbB-4。DAPT作为γ-分泌酶的抑制剂，在 β-淀粉样蛋白的形成研究中可能具有重要的应用价值。DAPT在自身免疫性和淋巴增生性疾病的研究中，如阿尔卑斯和红斑狼疮(SLE)，以及在癌细胞生长、血管生成和人类诱导多能干细胞(hIPSC)分化中的作用已被证明可以抑制Notch信号。

索取COA

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is Product D5942, DAPT soluble in?

    DAPT is soluble in DMSO at approximately 18 mg/ml.

  4. Are solutions of Product D5942, DAPT stable?

    Sigma has not evaluated the solution stability of DAPT. However, in a study of cultured insect cells, DAPT inhibited γ-secretase activity for 12 hours, which is indicative of its stability in solution at a presumed 37 °C temperature. Pitsi, D., and Octave, J.N., Presenilin 1 stabilizes the C-terminal fragment of the amyloid precursor protein independently of γ-secretase activity. J. Biol. Chem., 279(24), 25333-25338 (2004).

  5. Is Product D5942, DAPT, a reversible or irreversible inhibitor of beta secretase?

    The literature indicates that in a treatment of PDAPP neuronal cultures with DAPT, removal of DAPT from the protocol restores amyloid precursor protein β production. This implies that DAPT may be a reversible inhibitor. Dovey, H.F., et al. Functional gamma-secretase inhibitors reduce beta-amyloid peptide levels in brain. J. Neurochem., 76(1), 173-181 (2001).
