9H-Carbazol-9-ol is a minor product converted from 9H-carbazole. 9H-Carbazole and its derivatives are of special pharmaceutical interest due to their versatile biological activities.
9H-Carbazole itself was found to be an inhibitor of
angiogenesis and inflammation.
Furthermore, 9H-carbazole is a basic structural element of
a variety of naturally active and synthetic compounds with
a broad range of action, showing antibacterial, antifungal, antiparasitic
, antiviral,
anticancer, adrenoceptor blocking
, or protein-kinase inhibition activities[1].
