Visnagin is an organic chemical compound with the molecular formula C13H10O4 It is a furanochromone, a compound derivative of chromone (1,4-benzopyrone) and furan.

History

[edit]

Visnaga daucoides, the main source for visnagin, has been used in traditional medicine in the Middle East to ease urinary tract pain associated with kidney stones and to promote stone passage.[2]

Occurrences

[edit]

Visnagin naturally occurs in Visnaga daucoides, a species of flowering plant in the carrot family known by many common names, including bisnaga, toothpickweed, and khella. Visnagin-containing khella seeds are usually found mainly in Middle East countries such as Egypt and Turkey and also in Northern African countries such as Morocco. Visnagin can be extracted directly from khella seeds.

Synthesis

[edit]

Modified synthesis of the naturally occurring visnagin is reported. Starting from phloroghrcin aldehyde, and building on the 2-methyl-y-pyrone, 2-methyl-5,7-dihydroxy-dfo-yl-chromone was obtained. Construction of the furan moiety was realized by a conventional method through the 7-carboxymethoxy ether giving S-norvisnagin which can be methylated to visnagin.[3]

Reactions

[edit]

Condensation

[edit]

Visnagin analogs can be synthesized through the condensation of visnagone with esters and sodium. This leads to the product of 2-ethyl, 2-(3'-pyridyl) visnagin analog (50c).[4] Visnagin Reaction[4]

Oligomerization

[edit]

Visnagin molecules can go over an oligomerization to form a chain of visnagin molecules.[5]

Visnagin olygomerization reaction

Animal study

[edit]

Visnagin has biological activity in animal models as a vasodilator and reduces blood pressure by inhibiting calcium influx into the cell.[6] In rats, visnagin prevents the formation of kidney stones by prolonging the induction time of nucleation of crystals.[7] On December 8, 2014, it was reported that "visnagin protects against doxorubicin-induced cardiomyopathy through modulation of mitochondrial malate dehydrogenase."[8] In another scientific study, it was reported that visnagin treatment reduced ischemia-reperfusion associated testicular injury in urological interventions.
