Calanolides and analogues thereof that demonstrate potent mycobacterium activity are provided. Also provided is a method of using calanolides and analogues thereof for treating or preventing mycobacterium infections. The calanolides and analogues thereof provided are obtained via syntheses employing chromene 4 and chromanone 7 as key intermediates.
This invention relates to a method for the analysis of a (at least one) target non-proteinaceous component of a mixture of non-proteinaceous and proteinaceous components derived from a biological sample using a protease from a Bacillus strain. The invention further relates to a method for the analysis of a (at least one) target nucleic acid component of a mixture of non-proteinaceous components, which comprise nucleic acids, and proteinaceous components whereby the mixture is derived from a biological sample comprising the steps of incubating the mixture with a (at least one) protease from a Bacillus strain, optionally amplifying the (at least one) target nucleic acid component, and determining or detecting the (at least one) target nucleic acid component.
