Applicazioni

Citric acid was used as a test reagent for studying whether the novel pyridazinylpiperazine analog TPRV-1 inhibitor can reduce cough reflex induced by citric acid and capsaicin in guinea pig.

Azioni biochim/fisiol

Citric acid in dietary form can augments absorption of aluminium in antacids. It also facilitates the phytoremediation of heavy metal contaminated soil and can transform cadmium into more transportable forms.

Cough reflex can be induced by the pepper extract capsaicin and by low pH in guinea-pig airways. Transient receptor potential vanniloid-1 (TPRV-1) is expressed in the sensory and afferent nerve fibres in airways. We hypothesized that a novel pyridazinylpiperazine analog
