The endogenous peptides with opiate-like activity. The three major classes currently recognized are the ENKEPHALINS, the DYNORPHINS, and the ENDORPHINS. Each of these families derives from different precursors, proenkephalin, prodynorphin, and PRO-OPIOMELANOCORTIN, respectively. There are also at least three classes of OPIOID RECEPTORS, but the peptide families do not map to the receptors in a simple way.
|Drug||Drug Name||Drug Description|
|DB00855||Aminolevulinic acid||A porphyrin precursor used to treat actinic keratosis of the face, scalp, and upper extremities, as well as to visualize a glioma.|
|DB08856||DADLE||A delta-selective opioid (ANALGESICS, OPIOID). It can cause transient depression of mean arterial blood pressure and heart rate.|
|DB08861||DPDPE||A heterodetic cyclic peptide that is a cyclic enkephalin analogue, having D-penicillaminyl residues located at positions 2 and 5, which form the heterocycle via a disulfide bond.|
