Naptalam is an herbicide.Naptalam is a dicarboxylic acid monoamide which results from addition of one equivalent of 1-naphthylamine to phthalic anhydride. It is a dicarboxylic acid monoamide, a carboxylic acid and a N-(1-naphthyl)carboxamide. It is a conj

7-Methoxy-1-naphthaleneacetic acid is an inhibitor of auxin action in plants. 7-Methoxy-1-naphthaleneacetic acid inhibits polar auxin transport and tropic responses associated with asymmetric auxin distribution in Arabidopsis and maize. 7-Methoxy-1-naphthaleneacetic acid inhibits auxin transport mediated by AUX1, PIN, and ABCB proteins expressed in yeast.

Norharmane-13C (Norharman-13C) is the 13C-labeled version of Norharmane. Norharmane (Norharman) is a β-carboline alkaloid and acts as a potent reversible inhibitor of monoamine oxidase (MAO), with IC50 values of 6.5 μM for MAO-A and 4.7 μM for MAO-B. It induces antidepressant effects and serves as a promising anticancer photosensitizer. Additionally, Norharmane significantly inhibits the growth of Arabidopsis seedlings by altering polar auxin transport through the inhibition of PIN2, PIN3, and PIN7 transport proteins.
