N,N-二乙基-4-氨基苯甲醛 MSDS4-Diethylaminobenzaldehyde
4-Diethylaminobenzaldehyde (DEAB) is reversible competitive inhibitor of ALDH1 (competitive with the aldehyde substrate) with a K i value of 4 nM, and irreversibly inactivates ALDH7A1 via formation of a stable, covalent acyl-enzyme species. The Temozolomide (TMZ)-resistant cell line LN18 is treated with a combination of TMZ and 4-Diethylaminobenzaldehyde for 10 days. As indicated by colony formation assay, the clonogenic capacity of LN18 cells exposed to TMZ in combination with 4-Diethylaminobenzaldehyde (DEAB) is significantly attenuated.
