“…Chloroquine (8) undergoes photochemical degradation in aqueous solutions (pH 7.4) on irradiation with 240-600 nm light. The major reaction leads to N-dealkylation to give several products including (9)- (11), which have been identified by MS and NMR spectrometry [49]. Some of the dealkylation reactions are shown in Figure 3.…”

“…Decomposition can generate toxic degradants and cause adverse side effects. For example, a photodegradation product of chloroquine led to toxic reactions, which could be hazardous to patients [5]. Instability can also lead to poor bioavailability due to pre-systemic loss of an active pharmaceutical ingredient (API).…”

“…O início do processo de degradação, com quebra da molécula, acontece na ligação α-C-H da cadeia lateral. Este processo de degradação é fortemente dependente da quantidade de oxigênio presente no meio, ou seja, se desencadeia e acontece sob condições aeróbicas KARLESEN;TØNNESEN, 1991;ANDERSEN;TØNNESEN, 1997;NORD et al, 1997;NORD, 1998).…”
