生物活性

4-Diethylaminobenzaldehyde is a reversible aldehyde dehydrogenases (ALDHs) inhibitor, with a Ki of 4 nM for ALDH1. 4-Diethylaminobenzaldehyde displays potent anti-androgenic effect (IC50= 1.71μM)[1][2].

体外研究
(In Vitro)

4-Diethylaminobenzaldehyde (DEAB) is reversible competitive inhibitor of ALDH1 (competitive with the aldehyde substrate) with a Ki value of 4 nM, and irreversibly inactivates ALDH7A1 via formation of a stable, covalent acyl-enzyme species[1].
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[3].
