| Phomopsin A | It is an acidic 13-membered cyclic hexapeptide-like metabolite with three unusual amino acids. It is a potent mycotoxin produced by the fungus, phomopsis leptostromiformis. It is an important bioprobe for understanding cellular structural proteins. It selectively binds to the dimeric tubulin at the overlap of vinblastine and maytansine, inhibits the formation of the microtubule spindle to block cell division. Synonyms: 2-Oxa-5,8-diazabicyclo[10.3.1]hexadecane, cyclic peptide deriv.; (2E)-(βS)-3-chloro-β,5-dihydroxy-N-methyl-L-tyrosyl-3,4-didehydro-L-valyl-3-hydroxy-L-isoleucyl-3,4-didehydro-L-prolyl-(2E)-2,3-didehydroisoleucyl-2,3-didehydro-aspartic acid, cyclic (15?3)-ether; NSC 381839; PMSA; Phomopsin. Grades: >98% by HPLC. CAS No. 64925-80-0. Molecular formula: C36H45ClN6O12. Mole weight: 789.23. |  |
| Phomopsin A | Phomopsin A is a cyclic hexapeptide mycotoxin isolated from the fungus Phomopsis leptostomiformis. Phomopsin A is a noncompetitive inhibitor of the binding of radiolabeled vincristine to tubulin [1]. Uses: Scientific research. Group: Natural products. CAS No. 64925-80-0. Pack Sizes: 1 mg. Product ID: HY-N6793. |  |
| Phomopsin A | Phomopsin A is an acidic 13-membered cyclic hexapeptide-like metabolite with three unusual amino acids linked in an "ansa" macrocycle with a three amino acid "tail", terminating in a dicarboxylic acid. Phomopsin A is a potent mycotoxin produced by the fungus Phomopsis leptostromiformis and is the causative agent of lupinosis in livestock fed infected lupins. Phomopsin A is an important bioprobe for understanding cellular structural proteins. It acts by selectively binding to dimeric tubulin, inhibiting the formation of the microtubule spindle to block cell division. Phomopsin A binds to tubulin at a site overlapping that of vinblastine and maytansine. Uniquely, phomopsin A protects tubulin from decay. Group: Biochemicals. Alternative Names: 2-Oxa-5, 8-diazabicyclo[10. 3. 1]hexadecane, cyclic peptide deriv.; 3-Chloro-erythro- β,5-dihydroxy-N-methyl-L-tyrosyl-3,4-didehydro-L-valyl-3-hydroxy-L-isoleucyl-3,4-didehydro-L-prolyl-(E)-2,3-didehydroisoleucyl-(E)-2,3-didehydroaspartic acid cyclic (15?3)-ether; NSC 381839. Grades: Highly Purified. CAS No. 64925-80-0. Pack Sizes: 1mg. US Biological Life Sciences. |  Worldwide |
| Phomopsinamine | Phomopsinamine is a potent mycotoxin and an effective microtubule inhibitor produced by the fungus, Phomopsis leptostromiformis. Phomopsinamine is formed by hydrolysis of the dicarboxylic acid of phomopsin A. Synonyms: Isoleucinamide, (βS)-3-chloro-β,5-dihydroxy-N-methyl-L-tyrosyl-3,4-didehydro-L-valyl-3-hydroxy-L-isoleucyl-3,4-didehydro-L-prolyl-2,3-didehydro-, cyclic (15?3)-ether, (2E)-; Phomopsinamine A; (2E)-(βS)-3-chloro-β,5-dihydroxy-N-methyl-L-tyrosyl-3,4-didehydro-L-valyl-3-hydroxy-L-isoleucyl-3,4-didehydro-L-prolyl-2,3-didehydro-isoleucinamide, cyclic (15?3)-ether; (S)-N-((E)-1-amino-3-methyl-1-oxopent-2-en-2-yl)-1-((3R,4S,7S,10S,11S)-15-chloro-3-ethyl-16,11-dihydroxy-3-methyl-10-(methylamino)-6,9-dioxo-7-(prop-1-en-2-yl)-2-oxa-5,8-diaza-1(1,3)-benzenacycloundecaphane-4-carbonyl)-2,5-dihydro-1H-pyrrole-2-carboxamide.
