Abstract
Cultivation of the endophytic fungus Robillarda sessilis XL-308 with SAHA resulted in the discovery of two previously undescribed cyclonerane sesquiterpenes (1 and 2), one previously unreported norcadinane type sesquiterpene (3), and seven suberanilohydroxamic acid (SAHA) derivatives (4–10). The identification of previously undescribed compounds was confirmed through NMR spectroscopic analyses, quantum chemistry calculations, and single-crystal X-ray crystallography. Among them, compounds 1 and 2 were products of the silenced genome in XL-308 that activated by SAHA. Concurrently, SAHA underwent biotransformation because of its moderate toxicity towards this fungus. It was hypothesized that the hydroxamic acid group in SAHA triggering the self-defense mechanism of XL-308 and converting SAHA into a less toxic derivative 5.
期刊介绍:
Phytochemistry is a leading international journal publishing studies of plant chemistry, biochemistry, molecular biology and genetics, structure and bioactivities of phytochemicals, including ''-omics'' and bioinformatics/computational biology approaches. Phytochemistry is a primary source for papers dealing with phytochemicals, especially reports concerning their biosynthesis, regulation, and biological properties both in planta and as bioactive principles. Articles are published online as soon as possible as Articles-in-Press and in 12 volumes per year. Occasional topic-focussed special issues are published composed of papers from invited authors.
