Discussion

Experimental analysis reveals 1,4-dihydropyridine derivatives enhance intestinal motility, suggesting new therapeutic applications.

Compounds 62 and 65 selectively relaxed intestinal smooth muscle, enhancing gut motility without causing pain.
Spasmolytic activity was confirmed through ex vivo testing of 1,4-dihydropyridine derivatives on isolated guinea pig tissues.
The derivatives exhibited favorable profiles in microbiota assessments, showing no negative effects on beneficial bacteria.
The study supports the potential repurposing of these compounds for functional bowel disorders requiring improved intestinal motility.

Camarda et al. (2025) studied this question.
