title: Studies on new phosphate ester antifungal antibiotics phoslactomycins. II. Structure elucidation of phoslactomycins A to F.
abstract: Phoslactomycins A to F are new antifungal antibiotics produced by Streptomyces nigrescens SC-273. On the basis of physico-chemical properties and NMR studies, their structures have been determined as shown in Fig. 6. They are characterized by possessing alpha, beta-unsaturated delta-lactone, phosphate ester, conjugated diene and cyclohexane ring moieties. The structural difference between them is ascribed to a substituent bound to the cyclohexane ring.
