derivati de opium (ai opiumului) cu 5 nuclee aromatice


Explanation:
Pentru cei cu cunostinte de chimie: cele cinci nuclee nu sunt neaparat de benzen, ci pot fi eventual si altele, posibil heterociclice. De aceea recomand aceasta versiune, ca fiind mai cuprinzatoare si totodata mai putin expusa erorilor.
Termenul 'derivati de opium' pare mai frecvent decat 'derivati ai opiu(m)ului' sau 'derivati opiacei'.

Atentie, fenantrenul are doar 3 nuclee aromatice (benzenice)! Celelalte doua nuclee ale substantei noastre pot fi de diferite structuri, posibil heterociclice (continand azot, oxigen sulf etc.)

neutral  Mihaela Petrican: variantă perfectă pentru a traduce "aromatic nuclei". În plus, cuvântul românesc este opiu (vezi DEX-ul) - opium este termenul latin

opioide (derivaţi ai opiului) cu 5 inele


Explanation:
opioide (derivaţi ai opiului) cu 5 inele (nuclee)

http://www.druginfoline.ro/drugori.cfm?main=383

aici există şi inele (nuclee) care nu sunt aromatice

ex. dacă vă uitaţi la structura morfinei sau codeinei


şi sunt derivaţi ai fenantrenului

pentaciclici sunt, deoarece la "inele" li se spune mai des "cicluri", dar nu toată molecula este aromatică, ci prezintă un singur nucleu de acest tip, are doar o "porţiune aromatică", nu 5 inele aromatice

The Opioid Receptor
As shown above, the opioid receptor is thought to have three main binding areas. There is an anionic site (8 by 6.5 angstroms) that bonds to the charged nitrogen of morphine, a cavity which accomodates the piperidine ring, and a flat surface for binding the aromatic portion of the molecule. All active agonists and antagonists must fit this receptor to some degree. There appear to be four receptor subtypes, termed mu (the morphine receptor), sigma (the phencyclidine receptor), kappa (the ketocyclazocine receptor) and delta (the endorphin/enkephalin receptor).

Morphine has five rings.
Each ring has been assigned with a letter (A, B, C, D and E).
Ring A, aromatic ring
Ring B, cyclohexane ring
Ring C, cyclohexen ring
Ring D, piperidine ring
Ring E, tetrahydrofuran ring

Morphine itself comprises a 5-ring structure, incorporating a partially hydrogenated phenanthrene ring system. Each ring of morphine is designated as set forth below: ##STR1##

http://www.patentstorm.us/patents/6469170-description.html

morfina este un derivat al opiului

http://pubs.acs.org/cen/coverstory/83/8325/8325morphine.html

fenantrenul este un compus aromatic, dar aici este parţial hidrogenat

iar în loc de "derivaţi ai opiului" (pt. care am găsit o sing. ref. ceea ce m-a pus puţin pe gânduri) este mai potrivit să se folosească termenul de "constituenţi ai opiului", nu este derivat în sensul de derivat chimic:

1. S.m. (Chim.) Substanţă preparată din alta şi care de obicei păstrează structura de bază a substanţei din care provine.

în schimb aceste substanţe din opiu sunt derivaţi (în sens chimic) ai fenantrenului
