The fungal F00734 was cultured using half sea-water Potato Dextrose Agar medium at 28 degrees celsius for 14 days. The
(10 liters) was extracted with ethyl acetate (EtOAc). The EtOAc extract (5.0 g) which was subjected to over RP-18, eluted with Methanol-H2O (30%, 50%, 70%, 100%; V/V) to yield 10 fractions. Fraction 5, eluted with methanol was further puried by Sephadex LH-20 Then merged the components 1–15 tubes eluted with acetone, and further purified by silica-gel to afford the title compound 1 (140.0 mg). F00734 is an high-yield strain of cyclopenol (2.8%).H atoms were positioned geometrically and were treated as riding on their parent atoms, with C—H distances of 0.93–0.98 Å, an N—H distance of 0.86 Å, and O—H distance of 0.82Å and Uiso(H)=1.2Ueq(N,C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compund named cyclopenol is an benzodiazepine metabolite produced by a number of Penicllium species. Cyclopenol isolated from Penicillium cyclopium Westling (Birkinshaw et al., 1963). It display intermediate in the biosynthesis of viridicatins, inhibitors of the TNF-α-induced replication of human HIV (Nover & Luckner, 1969; Heguy, et al., 1998). It is of ecological significance due to its phytotoxic and antimicrobial properties (Cutler, et al., 1984). In our study, we determined the crystal structure of the title compound. The seven membered ring adopts a boat conformation. The crystal packing is stabilized by intermolecular N—H···O and O—H···O hydrogen bondings (Table 1).
