This study reports the synthesis of steroidal quaternary ammonium compounds 11 and 12, with quaternary nitrogen at position 3 and 16 of the steroid nucleus in 5α-epiandrosterone series; along with their neuromuscular blocking activity using chick biventer cervicis muscle preparation. The compound 12 was found to be five times more potent than 11 in reducing twitch response to nerve stimulations, indicating the importance of extended interonium distances and 17-acetoxy function for potent antagonist activity.
