IUPAC Name: (7α,11α,17α)-9,11-epoxy-17-hydroxy-3-oxopregn-4-ene-7,21-dicarboxylic acid γ-lactone methyl ester
Structural Information
- Structure Type: Selective steroid mineralocorticoid receptor antagonist
- Structural Features: Pregnane steroid four-ring skeleton, 9α,11α-epoxy bridge, 7α-methyl carboxylate, 17-position γ-lactone ring; high selectivity for aldosterone receptor, low affinity to androgen/progesterone receptors
Physical & Chemical Properties
- Appearance: White to off-white crystalline powder, odorless
- Melting Point: 241–243 °C
- Specific Rotation: [α]20/D +5° (c=0.437, chloroform)
- Density: 1.31 g/cm3
- Solubility: Very slightly soluble in water; soluble in DMSO, methanol, ethanol; insoluble in alkane solvents
- Stability: Non-hygroscopic; stable under dry, light-proof sealed storage; stable in neutral/weak acid; prone to ester hydrolysis under strong alkaline heating
Synthesis & Applications
Production Method
Multi-step chiral steroid synthesis: construct pregnane core, epoxy cyclization, carboxylation, lactonization, methyl esterification, refined by recrystallization.
