  Removal of Electrophilic Potential Genotoxic Impurities Using Nucleophilic Reactive Resins

  摘要：

  Potential genotoxic impurities (PGI) are chemical compounds that could potentially damage DNA and lead to mutation. Controlling the occurrence of PGIs in active pharmaceutical ingredients (APIs) poses a big challenge for chemists, as levels of these compounds must be reduced well below the amounts required for other types of less toxic impurities. In situations where formation of PGIs cannot be avoided, an ideal solution would allow the complete removal of PGIs after the synthesis is complete, for example, by recrystallization, preparative chromatography or other downstream processing approaches. Some disadvantages of using these approaches are potential high yield loss, high solvent consumption, and additional time and resources required for process development. In this work, we present a simple and rapid approach to remove electrophilic PGIs from APIs. A selected nucleophilic resin can be added to the final API solution to reduce or totally remove the PGI. Esters of methanesulfonic acid (MSA), benzenesulfonic acid (BSA), and p-toluenesulfonic acid (pTSA) were used as model electrophilic PGIs. Several nucleophilic resins were screened, and the resins with the highest efficiency of PGI removal were chosen. A recommended procedure is presented for the removal of MSA, BSA, and pTSA esters. The kinetics of PGI removal, resin loading capacity, solvent effects, and API matrix effects are demonstrated.

The obtained results suggest the same kinetic mechanism of solvolysis of arenesulfonyl chlorides for propan‐1‐ol and propan‐2‐ol, as in MeOH and EtOH, where bimolecular nucleophilic substitution (SN2) takes place with nucleophilic solvent assistance of one alcohol molecule and the participation of the solvent network involving solvent molecules

  Ortho lithiation technology using alkyl benzenesulfonates has been developed to prepare a series of 2,6-disubstituted benzenesulfonates, benzenesulfonic acids and benzenesulfonyl chlorides. By comparison with other ortho directing groups, alkyl sulfonates are very powerful, leading to excellent regioselectivity.

  Methyl, ethyl, and isopropyl esters of six alkanesulfonic acids and five p-substituted benzenesulfonic acids were synthesized and their alkylating abilities were evaluated in terms of the chemoselectivity toward 4-(p-nitrobenzyl) pyridine (NBP) in phosphate buffer (pH 6.0) containing 60% acetone. The chemoselectivity constant toward NBP, SNBP, was defined as the logarithm of the ratio of the molar fraction of an alkylating sulfonate which is consumed for alkylation of NBP versus the molar fraction of the residual alkylating agent which is hydrolyzed in the buffer medium. It was found that SNBP was not only markedly dependent on the structure of the alkyl moiety of the molecule, but also appreciably dependent on the electronic nature of the leaving sulfonic acid moiety. The structure-chemoselectivity relationship is discussed.
