Description
A new cyclodepsipeptide, designated roseocardin, was isolated from the culture broth of Trichothecium roseum TT103. Roseocardin as well as the other cyclodepsipeptides were shown to produce positive inotropic effects on rat heart muscles.

1. Non-cyclic AMP-dependent, positive inotropic cyclodepsipeptides with negative chronotropy
A Tsunoo, M Kamijo J Pharmacol Exp Ther. 1999 Sep;290(3):1006-12.
The effects of natural cyclodepsipeptides (CDPs) on isolated rat cardiac tissue preparations were examined in vitro. Destruxin A, destruxin B (DB), roseotoxin B (RB), and roseocardin (RC), a novel CDP, each caused a concentration-dependent increase in the contraction force of the right atrium and the papillary and trabecular muscles of the right ventricle at 0.6 to 600 microM. RB, destruxin A, and DB did not affect the half-decay time of relaxation of the papillary muscles, but RC slightly prolonged it, although to a much lesser extent than BA 41899, a calcium sensitizer. This inotropic effect is accompanied by a prolongation of the automatic atrial contraction intervals. The RB-induced increase in the contraction force of papillary muscle was not affected by phentolamine, propranolol, pyrilamine, or cimetidine. RB- and RC-induced increases in the contraction force of papillary muscles were not affected by 3-isobutyl-1-methylxanthine or carbachol. Neither peptide changed the cyclic AMP levels in trabecular muscles. Neither RB nor RC affected the activity of Na(+),K(+)-ATPase from rat kidney. Neither RB, RC, nor DB affected the resting membrane potential or the apparent input resistance of papillary muscles. These results suggest that these CDPs produce both non-cyclic AMP-dependent positive inotropic and negative chronotropic effects.
2. Roseocardin, a novel cardiotonic cyclodepsipeptide from Trichothecium roseum TT103
A Tsunoo, M Kamijo, N Taketomo, Y Sato, K Ajisaka J Antibiot (Tokyo). 1997 Dec;50(12):1007-13. doi: 10.7164/antibiotics.50.1007.
A new cyclodepsipeptide, designated roseocardin, was isolated from the culture broth of Trichothecium roseum TT103. Roseotoxin B and destruxins A and B were also isolated during the same procedure. The structure of roseocardin was determined by EI-MS, NMR and X-ray crystallographic analysis. Roseocardin as well as the other cyclodepsipeptides were shown to produce positive inotropic effects on rat heart muscles.
