Three marine alkaloids, purified from Clavelina moluccensis, were structurally identified as lepadiformines A, B, and C and studied on frog atrial myocytes I(K1), using the patch-clamp technique. Lepadiformine A (0.4 to 3.

Pharmacomodulation was carried out at N-1 and C-5 of the indole ring and at the level of the propanamide chain. N-(pyridin-3-ylmethyl)-3-[5-chloro-1-(4-chlorobenzyl)-indol-3-yl]propanamide 32 represents one of the most potent compounds evaluated in the TPA-induced mouse ear swelling assay, with a level of activity higher than that of ibuprofen and comparable to that of dexamethasone.

Pharmacomodulation was carried out on the indole and amidic nitrogens by incorporation of substituents associated with higher potency in previously synthesized related 3-indolepropanamides series. In the inhibition of topical inflammation determined by reduction of ear thickness in the acute PMA mouse ear swelling test, high levels of activity (ID50 approximately 0.
