Isotuberculosinol, also called nosyberkol or edaxadiene is a diterpene molecule produced by the bacterium Mycobacterium tuberculosis, the causative agent of TB, which aids in its pathogenesis. Isotuberculosinol functions by preventing maturation of the host-cell phagosome in which the bacterium lives.[1][2] Maturation of the phagosome would enable it to kill the bacterium. Mutations in genes involved in the biosynthetic pathway of nosyberkol result in normal development of the phagosome and reduction of mycobacterial infection. These biosynthetic genes include isotuberculosinol synthase.


Nosyberkol was originally isolated in 2004 from a marine sponge in the ocean near island of Nosy Be after which it was named.[3] The molecule was characterised as a triterpene but the structure was revised following its chemical synthesis in 2010.[4]

Zucchini (courgette) A striped and a uniform color zucchini Genus Cucurbita Species Cucurbita pepo Origin 19th century northern Italy The zucchini ( / z uː ˈ k iː n i / , American English) or courgette ( / k ʊər ˈ ʒ ɛ t / , British English) is a summer squash which can reach nearly 1 metre (100 cm; 39 in) in length, but is usually harvested when still immature at about 15 to 25 cm (6 to 10 in). [1] A zucchini is a thin-skinned cultivar of what in Britain and Ireland is referred to as a marrow. [2] [3] In South Africa, a zucchini is known as a baby marrow. Along with certain other squashes and pumpkins, the zucchini belongs to the species Cucurbita pepo . It can be dark or light green. A related hybrid, the golden zucchini, is a deep yellow or orange color. [4] In a culinary context, the zucchini is treated as a vegetable; it is usually cooked and presented as a savory dish o
