1. Basic Information
Name: Cyclopenta(c)pyrrole-1-carboxamide, (2S)-2-cyclohexyl-N-(pyrazinylcarbonyl)glycyl-3-methyl-L-valyl-N-((1S)-1-((cyclopropylamino)oxoacetyl)butyl)octahydro-, (1S,3aR,6aS)-
Alias: Telaprevir, VX-950
CAS No.: 402957-28-2
Molecular Formula: C36H53N7O6
Molecular Weight: 679.85
Category: Chiral peptide macrocyclic antiviral active pharmaceutical ingredient (API)
2. Physical and Chemical Properties
Physical Properties
- Appearance: White to off-white crystalline powder
- Odor: Odorless polypeptide solid
- Solubility: Soluble in DMSO, methanol, ethanol, acetonitrile, dichloromethane; slightly soluble in ethyl acetate; insoluble in aliphatic alkanes and pure water
- Melting Behavior: Decomposes on heating without sharp melting point
- Hygroscopy: Slightly hygroscopic under high humidity environment
- Aqueous Property: Highly lipophilic multi-amide compound; only forms homogeneous solution with polar aprotic organic co-solvents
Chemical Properties
- Molecular Structure: Multi-chiral octahydrocyclopenta[c]pyrrole bicyclic scaffold linked with multiple peptide amide chains, containing pyrazine ring, cyclohexyl, tert-butyl, cyclopropylamide and diketone side chain; all chiral centers maintain fixed stereoconfiguration
- Amide Bond Characteristics: Multiple peptide amide bonds are stable under neutral and weakly acidic conditions; hydrolyze under strong alkaline heating to produce fragmented amino acid derivatives
- Ketone Group Reactivity: Vicinal diketone moiety can undergo nucleophilic addition and reductive derivatization reactions
- Thermal Stability: Long-term stable at 2–8 °C cold storage; rapid chiral epimerization and oxidative degradation at room temperature with prolonged exposure
- Photostability: Extremely sensitive to UV light; illumination triggers skeleton oxidation and racemization of chiral centers
- Compatibility: Compatible with anhydrous polar organic solvents; incompatible with strong oxidants, concentrated strong alkali, heavy metal ions and high-temperature acidic conditions

Safety Warning
High-potency bioactive irritant polypeptide powder. Dust causes severe irritation to eyes, respiratory tract and skin; long-term skin contact may induce erythema and allergic dermatitis. All handling operations must be carried out inside ventilated chemical fume hoods with dust respirators, chemical-resistant gloves and full-face safety goggles. Mandatory low-temperature light-proof airtight storage to avoid chiral racemization and loss of antiviral activity. Waste liquid requires anhydrous solvent recovery and neutralization treatment; solid waste is classified as high-potency pharmaceutical hazardous waste and must be disposed by licensed professional hazardous waste treatment facilities.
