cleistanthin B Usage And Synthesis

Uses

Cleistanthin B (Diphyllin O-glucoside) is an orally active arylnaphthalene lignan lactone glycoside. Cleistanthin B exhibits anti-SARS-CoV-2 effects in Vero cells, with EC50 of 6.51 μM. Cleistanthin B also exhibits antitumor, diuretic and antihypertensive effects in vivo[1][2][3][4].

Definition

ChEBI: A member of the class of cleistanthins that is cleistanthin A in which the 3,4-di-O-methyl-D-xylopyranosyl group is replaced by a beta-D-glucopyranosyl group.
