Libiguin A is a naturally occurring limonoid found in Neobeguea mahafalensis, a flowering plant found in Madagascar with a long history of traditional medical use.[1][2][3][4][5] It is a derivative of phragmalin.[1] The compound has been reported to produce highly potent, strong, and long-lasting pro-sexual effects in rodents.[1][5] The semisynthesis of libiguin A from phragmalin has been described.[2] An analogue also found in Neobeguea mahafalensis, libiguin B, has similar pro-sexual effects but is far less potent in comparison.[1][2][5] Another analogue, a synthetic compound known as volufralin (LIB-01; DIC-2024), is under development for the treatment of erectile dysfunction and premature ejaculation.[6][7] Libiguin A was first described in the scientific literature by 2014.[1][2]

3.1.14. Neobeguea. As described in Fig. 15, 11 new limonoids, namely, dodoguin 313, dormir A–G 314–320, 108 libiguins A 321, libiguins B (a) 322 and libiguins B (b) 323, 109 were isolated from the root barks of Neobeguea mahafalensis, a medicinal plant in Madagascar. Interestingly, compounds 318, and 321–323 contained a C-16/30 d-lactone ring, which was the rst time reported in this species. [...] compound 322 exhibited a potent sexual enhancing activity.

Neobeguea mahafalensis is the source of the phragmalin derivatives libiguin A 560 and libiguin B 561 (in equilibrium with its keto tautomer).202 These compounds are reported to have aphrodisiac properties.
