Steroid compounds having various oxygen substitution on the steroid nucleus are disclosed. A specific functionality present on many of the steroid compounds is oxygen substitution at both of positions 6 and 7. Thus, certain steroids have oxygen substitution at C6 and C7, and some have specific stereochemistries such as 6&agr; and 7&bgr; oxygen substitution, and an alpha hydrogen at the 5 position in addition to having 6&agr; and 7&bgr; oxygen substitution. Steroids having 3,4-epoxy functionality are also disclosed. In addition, steroids having C17 pyran and &dgr;-lactone functionality, with oxygen substitution at C6 and C7, or at C15, of the steroid nucleus, are disclosed.
揭示了在类固醇核上具有各种氧替代的类固醇化合物。许多类固醇化合物上具有的一种特定的功能是在6和7的位置都有氧替代。因此,某些类固醇具有C6和C7的氧替代,有些具有特定的立体化学,例如6&agr;和7&bgr;的氧替代,并且在5位置还具有一个α-氢原子,除了具有6&agr;和7&bgr;的氧替代。还披露了具有3,4-环氧功能的类固醇。此外,还揭示了具有C17吡喃和&dgr;-内酯功能,在类固醇核的C6和C7或C15处具有氧替代的类固醇。
