Selective interaction of homophtalazine derivatives with morphine
European Journal of Pharmacology, 1997Homophtalazines show specific binding sites in the nigrostriatal system and to find their target of action the interactions between these derivatives, nerisopam and girisopam, and chlorpromazine, chlordiazepoxide and morphine were assessed. The compounds did not influence the chlorpromazine induced decrease in motility and catalepsy, nor did they alter

Color Reactions of Morphine Derivatives.
Journal of Chemical & Engineering Data, 1966T o CHECK the specificity of various tests for heroin, several esters of morphine and dihydromorphine were synthesized. These esters were treated with color-producing reagents and the results noted in Table I. Crystalline solids were obtained in other tests and the results are listed in Table 11.

Biosynthesis of unnatural morphine derivatives in Papaver somniferum
Journal of the Chemical Society, Perkin Transactions 1, 1972Demethylation of various codeine derivatives to give the corresponding, unnatural derivatives of morphine has been studied in Papaver somniferum. The efficiencies of the unnatural processes have been compared with that of the natural, codeine into morphine, conversion by feeding mixtures of [2-3H]-labelled codeine derivatives with [N-methyl-14C]codeine.

Current Medicinal Chemistry, 2001
The reactions of morphine and its derivatives with phenyliodo(III)diacetate (PIDA) have been studied. This methodology has not been introduced to morphine alkaloids, despite the fact that such a strategy would ensure dearomatization of the electrophilic aromatic ring of morphine derivatives leading to nucleophilic ortho-quinoidal structures with ...

Poisoning due to Opiates and Morphine Derivatives
1981The deliberate self-administration of an opiate drug is a relatively common cause of poisoning in Great Britain, the USA and Europe. The group of opiate drugs is large and includes apomorphine, buprenor-phine, codeine and dihydrocodeine (DF 118), dextro-moramide, dextropropoxyphene (propoxyphene), diamorphine (diacetylmorphine, heroin), dipipanone ...
