Pegaspargase is a conjugate of monomethoxypolyethylene glycol (mPEG) and L-asparaginase (L-asparagine amidohydrolase), an asparagine-specific enzyme that converts L-asparagine into aspartic acid and ammonia. Asparagine is an amino acid that is vital for cell survival. In humans, most normal tissues can produce asparagine through the action of asparagine synthetase. However, leukemia cells have low levels of this enzyme and depend on exogenous sources. Therefore, the use of pegaspargase results in leukemic cell death.[A103,A255912,L44667] Pegaspargase has the same mechanism of action as [L-asparaginase] derived from _Escherichia coli_, a previously developed enzyme used for the treatment of acute lymphoblastic leukemia (ALL). However, using L-asparaginase derived from _Escherich
Ketoconazole is an imidazole antifungal agent used in the prevention and treatment of a variety of fungal infections.[FDA Label] It functions by preventing the synthesis of ergosterol, the fungal equivalent of cholesterol, thereby increasing membrane fluidity and preventing growth of the fungus.[A181802,T116] Ketoconazole was first approved in an oral formulation for systemic use by the FDA in 1981. At this time it was considered a significant improvement over previous antifungals, [miconazole] and [clotrimazole], due to its broad spectrum and good absorption. However, it was discovered that ketoconazole produces frequent gastrointestinal side effects and dose-related hepatitis.[A188054,A188057] These effects combined with waning efficacy led to its eventual replacement by triazole agents, [fluconazole], [itraconazole], [voriconazole], and [posaconazole]. Ketoconazole and its predecessor [clotrimazole] continue to be used in topical formulations.
