  Benzothieno[3,2-b]quinolinium and 3-(phenylthio)quinolinium compounds: Synthesis and evaluation against opportunistic fungal pathogens

  摘要：

  Substitution around 5-methyl benzothieno[3,2-b] quinolinium (2) ring system was explored in order to identify positions of substitution that could improve its antifungal profile. The 3-methoxy (10b) was active against C. albicans, C. neoformans, and A. fumigatus and the 4-chloro (10f) analog showed moderate increases in anti-cryptococcal and anti-aspergillus activities. The effectiveness of 10b and 10f were validated in murine models of candidiasis and cryptococcosis, respectively. The efficacy of 10f in reducing brain cryptococcal infection and its observation in the brain of mice injected with this quaternary compound confirm the capacity of these compounds to cross the blood-brain barrier of mice. Overall, several of the chloro and methoxy substituted compounds showed significant improvements in activity against A. fumigatus, the fungal pathogen prevalent in patients receiving organ transplant. Opening the benzothiophene ring of 2 to form 1-(5-cyclohexylpentyl)-3-(phenylthio) quinolinium compound (3) resulted in the identification of several novel compounds with over 50-fold increases in potency (cf. 2) while retaining low cytotoxicities. Thus, compound 3 constitutes a new scaffold for development of drugs against opportunistic infections. Published by Elsevier Ltd.
