Paclitaxel degradation
The pH-rate curve for paclitaxel degradation shows a U-shape characteristic which suggests that a degree of catalysis occurs in both acidic and alkaline pH. Maximum stability is observed in the pH region from 3 to 5 [ 30 ]. At pH below 2.5, there is an acidic hydrolysis region in pH-rate profile. WebMar 14, 2024 · The degradation phenomenon is the lowest in the initial and leg phase, while it is the highest in the third phase. The released amounts of GA and LA monomers were increased by degradation, which leads to the diminishing of pH and consequently releasing the PTX. The main degradation mechanism in ISFIs is the autocatalytic hydrolysis of …
