| 10-deacetylbaccatine iii | 10-deacetylbaccatin III | |
| 6-hydroxytaxol | A taxane diterpenoid that consists of paclitaxel bearing an additional hydroxy substituent at the 6alpha-position. | 6-hydroxypaclitaxel |
| aphidicolin | A tetracyclic diterpenoid that has an tetradecahydro-8,11a-methanocyclohepta[a]naphthalene skeleton with two hydroxymethyl substituents at positions 4 and 9, two methyl substituents at positions 4 and 11b and two hydroxy substituents at positions 3 and 9. An antibiotic with antiviral and antimitotical properties. Aphidicolin is a reversible inhibitor of eukaryotic nuclear DNA replication. | aphidicolin |
| atractyligenine | A diterpenoid isolated from coffee silverskin. It inhibits cutaneous photoaging. | atractyligenin |
| baccatin iii | A tetracyclic diterpenoid isolated from plant species of the genus Taxus. | baccatin III |
| cabazitaxel | A tetracyclic diterpenoid that is 10-deacetylbaccatin III having O-methyl groups attached at positions 7 and 10 as well as an O-(2R,3S)-3-[(tert-butoxycarbonyl)amino]-2-hydroxy-3-phenylpropanoyl group attached at position 13. Acts as a microtubule inhibitor, binds tubulin and promotes microtubule assembly and simultaneously inhibits disassembly. | cabazitaxel |
| docetaxel anhydrous | A tetracyclic diterpenoid that is paclitaxel with the N-benzyloxycarbonyl group replaced by N-tert-butoxycarbonyl, and the acetoxy group at position 10 replaced by a hydroxy group. | docetaxel anhydrous |
| grayanotoxin i | A tetracyclic diterpenoid that is grayanotoxane in which the pro-R hydrogen at position 14 is substituted by an acetoxy group and in which the 3beta-, 5-, 6beta-, 10-, and 16- positions are substituted by hydroxy groups. | grayanotoxin I |
| ingenol | A tetracyclic diterpenoid that is 1a,2,5,5a,6,9,10,10a-octahydro-1H-2,8a-methanocyclopenta[a]cyclopropa[e][10]annulen-11-one substituted at positions 5, 5a and 6 by hydroxy groups, positions 1, 1, 7 and 9 by methyl groups, position 4 by a hydroxymethyl group and position 1 by an oxo group (the 1aR,2S,5R,5aR,6S,8aS,9R,10aR diastereomer). | ingenol |
| komaroviquinone | A tetracyclic diterpenoid isolated from Dracocephalum komarovii and has been shown to exhibit trypanocidal activity. | komaroviquinone |
| paclitaxel | A tetracyclic diterpenoid isolated originally from the bark of the Pacific yew tree, Taxus brevifolia. It is a mitotic inhibitor used in cancer chemotherapy. Note that the use of the former generic name 'taxol' is now limited, as Taxol is a registered trade mark. | paclitaxel |
| phorbol | A diterpenoid with the structure of tigliane hydroxylated at C-4, -9, -12(beta), -13 and -20, with an oxo group at C-3 and unsaturation at the 1- and 6-positions. | phorbol |
| rebaudioside a | A rebaudioside that is rubusoside in which the hydroxy groups at positions 3 and 4 of the beta-D-glucopyranosyloxy group at the 13alpha position have both been converted to the corresponding beta-D-glucopyranoside. | rebaudioside A |
| rebaudioside d | A rebaudioside that is rebaudioside A in which the hydroxy group at position 2 of the beta-D-glucosyl ester moiety has been converted to the corresponding beta-D-glucoside. Found in minute quantities in the leaves of Stevia rebaudiana. | rebaudioside D |
| rebaudioside m | A rebaudioside that is rebaudioside A in which the the hydroxy groups at positions 2 and 3 of the beta-D-glucosyl ester moiety have both been converted to the corresponding beta-D-glucoside. Found in very low concentraitions in the leaves of Stevia Rebaudiana, it is more than 200 times sweeter than sucrose. | rebaudioside M |
| rubusoside | A steviol glycoside that is steviol in which both the carboxy group and the tertiary allylic hydroxy group have been converted to their corresponding beta-D-glucosides. A precious bioactive natural sweetener which mainly exists the in Chinese sweet tea plant, Rubus suavissimus. | rubusoside |
| sordaricin | A tetracyclic diterpenoid that is produced by several fungi including Sordaria araneosa. | sordaricin |
| spongia-13(16),14-dien-19-oic acid | A tetracyclic diterpenoid that is 3b,4,5,5a,6,7,8,9,9a,9b,10,11-dodecahydrophenanthro[1,2-c]furan substituted by methyl groups at positions 3b, 6 and 9 and a carboxy group at position 6. Isolated from Spongia, it exhibits inhibitory activity against androgen receptor. | spongia-13(16),14-dien-19-oic acid |
| steviol | An ent-kaurane diterpenoid that is 5beta,8alpha,9beta,10alpha-kaur-16-en-18-oic acid in which the hydrogen at position 13 has been replaced by a hydroxy group. | steviol |
| stevioside | A diterpene glycoside that is rubusoside in which the hydroxy group at position 2 of the allylic beta-D-glucoside has been converted to the corresponding beta-D-glucoside. It is a natural herbal sweetener that is 250-300 times sweeter than sucrose (though with a bitter aftertaste), extracted from the Stevia rebaudiana plant native to South America. | stevioside |
| tiamulin | A carbotricyclic compound that is pleuromutilin in which the hydroxyacetate group is replaced by a 2-{[2-(diethylamino)ethyl]sulfanyl}acetate group. An antibacterial drug, tiamulin is used in veterinary medicine (generally as its hydrogen fumarate salt) for the treatment of swine dysentery caused by Serpulina hyodysenteriae. | tiamulin |
