Reference Reading

1. Fusacandins A and B; novel antifungal antibiotics of the papulacandin class from Fusarium sambucinum. II. Isolation and structural elucidation
J E Hochlowski, D N Whittern, A Buko, L Alder, J B McAlpine J Antibiot (Tokyo). 1995 Jul;48(7):614-8. doi: 10.7164/antibiotics.48.614.
Two novel antifungal compounds of the papulacandin class, named fusacandins A and B, have been isolated from Fusarium sambucinum. Each compound contains two units of galactose and one of glucose, the latter connected as a C-glycoside to an aromatic moiety. Fusacandin A is esterified at two sites with long-chain, unsaturated fatty acids and fusacandin B at only one site. The structures of the fusacandins were elucidated through analysis of mass spectral and 1-D and 2-D homonuclear and heteronuclear NMR data.
2. Fusacandins A and B; novel antifungal antibiotics of the papulacandin class from Fusarium sambucinum. I. Identity of the producing organism, fermentation and biological activity
M Jackson, D J Frost, J P Karwowski, P E Humphrey, S K Dahod, W S Choi, K Brandt, L H Malmberg, R R Rasmussen, M H Scherr, et al. J Antibiot (Tokyo). 1995 Jul;48(7):608-13. doi: 10.7164/antibiotics.48.608.
The fuscandins, antifungal agents of the papulacandin class, are produced by a strain of Fusarium sambucinum. Fermentation yielded 60 mg/liter of fusacandin A and minor amounts of fusacandin B. As expected, the fusacandins inhibit (1,3)-beta-glucan synthesis. Fusacandin A is slightly less active than papulacandin B against Candida albicans and, like papulacandin, loses activity in the presence of serum.
