4-Diethylaminobenzaldehyde 是醛脱氢酶(ALDHs)的可逆抑制剂，对 ALDH1 的 Ki 为 4 nM，具有较强的抗雄激素作用 ，IC50为1.71 μM。

Dyclonine hydrochloride (Dyclonine HCl) 是润喉片的有效成分，具有显著的杀菌和杀真菌作用。

4-Hydroxynonenal (4-HNE) 是一种 α，β 不饱和羟基烯醛，可作为氧化 亚硝化应激生物标志物。它是ALDH2的底物和抑制剂。它可以调节许多信号传导过程，主要是通过与蛋白质，核酸和膜脂质中具有亲核官能团的共价加合物形成的。它通过线粒体在癌症中起重要作用。

7-Hydroxy-4-phenylcoumarin是一种双重抑制剂，对ALDH-2和MAO的IC50值分别为1.5 µM和0.5 µM。

DOPAL is an aldehyde product of the oxidative deamination of dopamine by monoamine oxidase.[1] It can be further oxidized to 3,4-dihydroxyphenylacetic acid (DOPAC) by aldehyde dehydrogenase (ALDH) and, to a lesser extent reduced to 3,4-dihydroxyphenyl ethanol (DOPET). DOPAL is toxic to neurons.[2],[3] It can also oligomerize and precipitate α-synuclein, an event associated with Parkinson's disease.[2] Mice lacking cytosolic and mitochondrial forms of ALDH display increased levels of DOPAL as well as neurodegeneration and motor dysfunction characteristic of Parkinson’s disease.[4]

ALDH1A1-IN-4 (compound A1) 作为一种有效的乙醛脱氢酶 (ALDH) A1 抑制剂，其IC50为 0.32 μM，对癌症研究具有重要意义。

BODIPY-aminoacetaldehyde diethyl acetal (BAAA-DA) is a stable precursor to BODIPY-aminoacetaldehyde, a cell-permeable fluorescent substrate for aldehyde dehydrogenase (ALDH).1,2BODIPY-aminoacetaldehyde diethyl acetal is converted under acidic conditions to BODIPY-aminoacetaldehyde (BAAA).2BAAA is cell-permeant and is converted intracellularly by ALDH to BODIPY aminoacetate (BAA), which is retained by cells and can be used to identify cells with high ALDH activity.1BAA is a substrate for the efflux pump P-glycoprotein (P-gp) but co-application of BAAA with a P-gp inhibitor, such as verapamil , inhibits BAA efflux.2BAAA-DA has been used to isolate human hematopoietic progenitor cells, which have high ALDH activity, andviaflow cytometry to sort cancer stem cells that contain high levels of ALDH.1,3BAA used in cells can be excited at 488 nm and displays an emission maximum of 512 nm.4 1.Storms, R.W., Trujillo, A.P., Springer, J.B., et al.Isolation of primitive human hematopoietic progenitors on the basis of aldehyde dehydrogenase activityProceedings of the National Academy of Sciences of the United States of America96(16)9118-9123(1999) 2.Smith, C.A., Colvin, M., Storms, R.W., et al.BODIPY aminoacetaldehyde diethyl acetal08010501.81-15(2010) 3.Leng, Z., Yang, Z., Li, L., et al.A reliable method for the sorting and identification of ALDHhigh cancer stem cells by flow cytometryExp.

Nitrefazole 是一种4-nitroimidazole 衍生物，对醛脱氢酶(ALDH)具有强烈而持久的抑制作用，醛脱氢酶是一种参与酒精代谢的酶。

CVT-10216 是可逆的、选择性的醛脱氢酶 2（ALDH-2）抑制剂，IC50为 29 nM。对 ALDH-1的抑制作用较弱，IC50为 1.3 μM。 它可以减少偏爱酒精的大鼠过量饮酒，并表现出抗焦虑作用。
