title: A novel sesterterpenoid, nitiol, as a potent enhancer of IL-2 gene expression in a human T cell line, from the Peruvian folk medicine "Hercumpuri" (Gentianella nitida).
abstract: A novel sesterterpenoid designated as nitiol (1), possessing enhancement activity of IL-2 gene expression in a human T cell line, was isolated from the Peruvian folk medicine "Hercampuri" (Gentianella nitida). The structure was elucidated by extensive spectroscopic investigation.
