Tadalafil - an overview | ScienceDirect Topics
Analogs of tadalafil (53)-a clinically useful PDE5 inhibitor in human medicine-were screened against P. falciparum and it was demonstrated that there was a link between their antimalarial activity and their activity as hPDE5 inhibitors, implying that inhibition of Plasmodium phosphodiesterase(s) could be important to the antimalarial effect ...
Tadalafil - an overview | ScienceDirect Topics
Tadalafil is a potent and selective PDE5 inhibitor under regulatory review for the treatment of ED. In a clinical trial, tadalafil showed a clinical response in erectile function for up to 24 h postdosing. In both chemical structure and PDE subtype selectivity profile, tadalafil differs markedly from sildenafil and vardenafil.
