| alloin | A diastereoisomeric mixture of aloin A (barbaloin) and aloin B (isobarbaloin), which have similar properties. It is a bitter-tasting, yellow-brown colored compound found in the exudate of at least 68 Aloe species at levels of up to 6.6% of leaf dry weight (making between 3% and 35% of the total exudate), and in another 17 species at indeterminate levels. It is used as a stimulant-laxative, treating constipation by inducing bowel movements. | aloin |
| amrubicinol | A diastereoisomeric mixture resulting from the formal reduction of the acetyl group at position 9 of amrubicin to the corresponding 1-hydroxyethyl group. The active metabolite of amrubicin in lung cancer patients. | amrubicinol |
| buthionine sulfoximine | A sulfoximide that is the sulfoximine derivative of an analogue of DL-methionine in which the S-methyl group is replaced by S-butyl. | 2-amino-4-(S-butylsulfonimidoyl)butanoic acid; S-butyl-DL-homocysteine (S,R)-sulfoximine |
| golgicide a | A diastereoisomeric mixture comprising racemic cis- and racemic trans-goglioside A in a 10:1 ratio. It is a potent and rapidly reversible GBF1 (Golgi-specific brefeldin A-resistance guanine nucleotide exchange factor 1) inhibitor. The (3aS,4R,9bR) isomer is the most active (see Bioorg. Med. Chem. Lett., 2012, 22, 5177-5181). | golgicide A |
