| baeocystin | A tryptamine alkaloid that is N-methyltryptamine carrying an additional phosphoryloxy substituent at position 4. | baeocystin |
| benphothiamine | A thioester that is a synthetic analogue of thiamine obtained by acylative cleavage of the thiazole ring and O-phospohorylation. | benfotiamine |
| carboxy phosphate | An acyclic mixed acid anhydride formed by condensation of phosphoric acid with carbonic acid. | carboxyphosphoric acid |
| chlorfenvinphos | | chlorfenvinfos |
| diazoxon | An organic phosphate that is diethyl hydrogen phosphate in which the hydrogen of the hydroxy group has been replaced by a 6-methyl-2-(propan-2-yl)pyrimidin-4-yl group. It is a metabolite of the pesticide diazinon. | diazoxon |
| psilocybin | A tryptamine alkaloid that is N,N-dimethyltryptamine carrying an additional phosphoryloxy substituent at position 4. The major hallucinogenic alkaloid isolated from Psilocybe mushrooms (also known as Teonanacatl or "magic mushrooms"). | psilocybin |
| pyridoxal phosphate-6-azophenyl-2',4'-disulfonic acid | An arenesulfonic acid that is pyridoxal 5'-phosphate carrying an additional 2,4-disulfophenylazo substituent at position 6. | 5'-phosphopyridoxal-6-azobenzene-2,4-disulfonic acid |
| VPC 23019 | A secondary carboxamide resulting from the formal condensation of the carboxy group of O-phospho-D-serine with the amino group of m-octylaniline. An analogue of sphingosine-1-phosphate (S1P), it is a potent antagonist for both S1P1 and S1P3 receptors. It can inhibit S1P-induced migration of thyroid cancer cells, ovarian cancer cells, and neural stem cells. | VPC 23019 |
