Polypeptides bound to molecular scaffolds for disease treatment
A recently filed patent (Publication Number: US20230287047A1) describes a method for synthesizing compound BCY8245. The method involves a series of steps, starting with providing a compound of formula 7, followed by providing compounds of formulas 6, 5, 4, 3, 2, and 1. These compounds are then reacted and transformed into the desired compound BCY8245 or its salt using a solid-phase synthesis.
In one embodiment of the method (claim 29), the compound of formula 8 or its salt is reacted with BCY8234 or its salt in the presence of N,N-diisopropylethylamine (DIEA). Another embodiment (claim 30) involves the reaction of the compound of formula 7 or its salt with NHS in the presence of a carbodiimide, specifically 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCI).
The saponifying step (claim 32) in the method involves reacting the compound of formula 6 or its salt with LiOH and H2O. The compound of formula 5 or its salt is reacted with MMAE in the presence of N,N-diisopropylethylamine (DIEA) (claim 33). The compound of formula 4 or its salt is reacted with bis(4-nitrophenyl) carbonate in the presence of N,N-diisopropylethylamine (DIEA) (claim 34). The compound of formula 3 or its salt is reacted with (4-aminophenyl)methanol in the presence of N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ) (claim 35).
The hydrolyzing step (claim 36) in the method is performed under acidic conditions. Overall, the method provides a detailed process for synthesizing compound BCY8245 or its salt, involving a series of reactions and transformations.
In conclusion, the filed patent describes a method for synthesizing compound BCY8245 or its salt. The method involves a stepwise process starting with specific compounds and utilizing various reactions and transformations. The method provides a detailed and specific approach to produce the desired compound.
