BACKGROUND Point-of-care (POC) tests for diagnosing schistosomiasis include tests based on circulating antigen detection and urine reagent strip tests. If they had sufficient diagnostic accuracy they could replace conventional microscopy as they provide a quicker answer and are easier to use. OBJECTIVES To summarise the diagnostic accuracy of: a) urine reagent strip tests in detecting active ...
A simple, regioselective synthesis of di-indole sulfides by electrophilic aromatic substitution the C3-position indoles was achieved using Xtalfluor-E as sulfenylating reagent. The addition amine bases found to have a significant effect on reaction outcome, with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) switching off reactivity XtalFluor-E, while hindered base 2,6-ditertbutyl-4-methylpyridine (D...
