| Avermectin A1a | Avermectin A1a is produced by the strain of Streptomyces avermitilis. It stimulates nerve cells to release Y-aminobutyric acid (GABA), which blocks the transmission of signals from the central nervous system to the motor nerve. It is not resistant to bacteria and fungi, but has strong activity to nematode parasites such as ancylostoma and Pteria, as well as insects such as flies. Abamectin B1a has the highest activity. Ivermectin obtained by catalytic hydrogenation contains 22 23- dihydroabamectin B1a (above 80%) and 22 23 dioxabamectin B1b (below 20%). Less active than B1a but less toxic. Used as repellent (subcutaneous or oral) for cattle, sheep and pigs, it is also effective against human filariasis. Synonyms: SCHEMBL1681257. CAS No. 65195-51-9. Molecular formula: C49H74O14. Mole weight: 887.10. | |
| Avermectin B1a aglycone | It is an acid degradation product produced by hydrolysis of the disaccharide unit of avermectin. It is an inhibitor of nematode larval development.

Grade: >95% by HPLC. CAS No. 71828-14-3. Molecular formula: C34H48O8. Mole weight: 584.74. | |
| Avermectin B1a monosaccharide | It is an acid degradation product produced by selective hydrolysis of the terminal saccharide unit of avermectin. It is a potent inhibitor of nematode larval development. It has no paralytic activity. Synonyms: 4'-O-de(2,6-dideoxy-3-O-methyl-alpha-L-arabino-hexopyranosyl)-5-O-demethyl-avermectin A1a; 5-O-Demethyl-4'-O-de(2,6-dideoxy-3-O-methyl-α-L-glucopyranosyl)avermectin A1a; MSB 1a. Grade: >95% by HPLC. CAS No. 71831-09-9. Molecular formula: C41H60O11. Mole weight: 728.91. | |
| Averufin | Averufin is produced by the strain of Asergillus sp. Ames tests showed a weak mutagenic effect. Synonyms: Averufine; 3,4,5,6-Tetrahydro-7,9,11-trihydroxy-2-methyl-2,6-epoxy-2H-anthra[2,3-b]oxocin-8,13-dione. CAS No. 14016-29-6. Molecular formula: C20H16O7. Mole weight: 368.34. | |
| Avidinorubicin | Avidinorubicin is produced by the strain of Streptomyces avidinii. It has anti-gram positive and negative bacterial activity, and has cytotoxicity to tumor cells. Molecular formula: C60H86N4O22. Mole weight: 1215.34. | |
| Avrainvillamide | Avrainvillamide is a fungal metabolite and monomeric form of stephacidin B that has been found in A. ochraceus. It is active against S. aureus, S. pyogenes, and E. faecalis (MICs = 12.5, 12.5, and 25 μg/ml, respectively). Avrainvillamide inhibits the growth of LNCaP, BT-549, T47D, and MALME-3M cancer cells with GI50 values of 0.24, 0.62, 0.21, and 0.41 μM, respectively. Synonyms: CJ-17,665; CJ17,665; CJ 17,665; 3,11,12,13,13aS,14-hexahydro-3,3,14,14-tetramethyl-8H,10H-7aS,12aS-(iminomethano)indolizino[6,7-h]pyrano[3,2-a]carbazole-8,16-dione 15-oxide.
