These manufacturing routes produce fundamentally different impurity profiles: recombinant semaglutide has fermentation-related impurities (host cell proteins, residual DNA), while synthetic semaglutide has synthesis-related impurities (deletion sequences, diastereomers, incomplete acylation products)
Semaglutide works by slowing gastric emptying and altering central appetite signaling through GLP-1 receptor activation
Semaglutide appears to regulate appetite by increasing feelings of fullness
Another of the study's authors, Professor Francois Venter at the University of Witwatersrand in South Africa, said drugs to treat HIV, TB, malaria, and hepatitis are now available at prices close to production costs but still sufficient for generic manufacturers to operate
