However, in contrast to rhEPO that has shown side effects in clinical trials, to date ARA 290 has been shown to be safe when formally evaluated in preclinical animal toxicology, normal human volunteers and patients with sarcoidosis (1921)
Peptide structure and stability What peptides are: Chains of amino acids Held together by peptide bonds Specific 3D structure required for function Fragile molecules compared to small molecule drugs Why peptides are unstable: Peptide bonds susceptible to hydrolysis (water breaks bonds) Oxidation damages certain amino acids Temperature accelerates degradation Light exposure causes photo-degradation pH changes denature structure Bacterial contamination introduces enzymes that break peptides Degradation mechanisms: Temperature's exponential effect: Every 10C temperature increase roughly doubles degradation rate Room temperature (25C): Rapid degradation (days) Refrigerated (2-8C): Slow degradation (weeks-months) Frozen (-20C): Very slow degradation (years) Ultra-frozen (-80C): Minimal degradation (5+ years) Learn peptide fundamentals at SeekPeptides - explore what are peptides , how peptides work , and getting started with peptides
