The calculated %inhibition of ALDH1 activity by acrolein and BCNU in patients receiving BCNU in 4 split doses with CY was 81%, and it increased to 92% in single dose BCNU regimen.

We found that both ALDH isozymes were inhibited by acrolein, with IC50 values of 35 and 144 microM for ALDH-1 or ALDH-3, respectively.

Neither ALDH1A1 nor ALDH3A1 conferred any protection against acrolein, acetaldehyde, or chloroacetaldehyde.
We have developed transgenic cell lines to examine the potential for either human ALDH1A1 or ALDH3A1 to protect against damage mediated by these toxic aldehydes.

Overexpression of class 1 ALDH (ALDH-1) has been observed in cells selected for survival in the presence of OAPs.
Transfectants were cross-resistant to other OAPs but not to phosphoramide mustard, ifosfamide mustard, melphalan, or acrolein.

ALDH1A1 and ALDH3A1 gene expression data for the OS xenografts were mined from the Pediatric Preclinical Testing Program gene expression data.
They are pro-drugs and undergo hepatic metabolism into the active moiety and potentially toxic by-products such as acrolein and chloracetaldehyde, which may cause hemorrhagic cystitis and encephalopathy, respectively.
