Equisetin is an antibiotic produced by Fusarium equiseti NRRL 5537. Activity against gram-positive bacteria. Synonyms: (-)-Equisetin. Grades: >98%. CAS No. 57749-43-6. Molecular formula: C22H31NO4. Mole weight: 373.48.
The tetramic acid equisetin, is produced by a number of species of Fusarium. Interest in equisetin emerged with reports of its inhibitory activity against human immunodeficiency virus type 1 (HIV-1) integrase in vitro that was mechanistically distinct from previously described inhibitors. Equisetin inhibits 3' end-processing and strand transfer as well as disintegration catalysed by either the full-length enzyme or the truncated integrase core. Group: Biochemicals. Grades: Highly Purified. CAS No. 57749-43-6. Pack Sizes: 1mg. US Biological Life Sciences.

Fusarisetin A
It is an unusual pentacyclic metabolite related to equisetin isolated from Fusarium. It is identified from a natural product screen using a three-dimensional matrigel-induced bioassay to study acinar morphogenesis. It is the first inhibitor of acini reported in the literature. Synonyms: (+)-Fusarisetin A; 5H-Benz[4',5']indeno[2',1':3,4]furo[2,3-c]pyrrole-1,12(2H,5aH)-dione,3,3a,5b,7a,8,9,10,11,11a,11b-decahydro-3a-hydroxy-3-(hydroxymethyl)-2,5,9,11b-tetramethyl-, (3S, 3aR, 5S, 5aS, 5bS, 7aS, 9R, 11aR, 11bS, 12aR)-. Grades: >98% by HPLC. CAS No. 1300041-53-5. Molecular formula: C22H31NO5. Mole weight: 389.49.
