Papaverine, C20H21O4N. This alkaloid, first obtained by Merck, occurs in the mixture precipitated by ammonia from the mother liquors of opium extract from which morphine and codeine have been separated in Gregory s process, and methods for its isolation from this mixture have been published by Hesse and others. The alkaloid may be purified by conversion into the acid oxalate, B. H2C2O4, m.p. 196° or 201-5-202°, which is nearly insoluble in alcohol. 

Codeine, C18H21O3N. This alkaloid was isolated from opium by Robiquet in 1833. It occurs in opium to the extent of 0-1 to 3 per cent., and is isolated therefrom as the hydrochloride along with morphine hydrochloride in the first stage of Gregory s process. It is a methyl ether of morphine and is usually made from the latter by methylation, for which there are numerous patents. An extensive series of ethers of morphine and its isomerides, including ethers of the alcoholic hydroxyl group (Aeterocodeines) has been prepared by Faris and SmaU. ... 

Jsomerides of Morphine and Codeine. When morphine is treated with thionyl chloride, phosphorus trichloride or tribromide, the alcoholic hydroxyl group is replaced by the halogen, forming a-chloromorphide and bromomorphide respectively. The former on treatment with concentrated hydrochloric acid is converted into /3-chloromorphide. Schopf and Hirsch have provided evidence that the two are structural isomerides. With the same reagents codeine yields a parallel set of compounds, viz., a- and -chlorocodides, and bromocodide. The chief characteristics of these products may be summarised thus —... 

Thebaine, CjgHgiOgN. This base, which occurs in opium to the extent of 0-1 to 1 per cent., was first obtained by Pelletier and Thiboumery, who regarded it as isomeric with morphine, and named it paramorphine. It was examined by Kane, who first called it thebaine, and by Anderson, who described a method of isolation and provided the formula given above. It remains in the mother liquor after the removal of morphine and eodeine hydrochlorides in Gregory s process, and in Hesse s method of isolating it from this source is obtained as the acid tartrate. This is crystallised from hot water, and the alkaloid regenerated from it is reerystallised from dilute alcohol, from which it separates in leaflets, or from dry alcohol in prisms, m.p. 193°, — 218-6° (EtOH) or — 229-5°... 

The three alkaloids concerned, morphine, codeine and thebaine, all behave as tertiary bases. Morphine contains two hydroxyl groups of which one is phenolic and the other a secondary alcohol group. On methylation of the phenolic hydroxyl codeine results. On oxidation, codeine is transformed into codeinone by conversion of the secondary alcohol group into a carbonyl group, and when thebaine is boiled with A-sulphuric acid for a few minutes, it is hydrolysed into codeinone and methyl sulphate, and in other ways thebaine has been shown to contain two methoxyl groups. That the relationship between the three alkaloids is close may be illustrated by the following slightly extended formula —... 

Dihydromorphinone, Cj,Hjg03N, and derivatives. Dihydromorphinone (LIII MeO HO) is formed when morphine in solution is treated with relatively large quantities of platinum or palladium catalyst under various conditions.It melts at 262-3° and yields an oxime, m.p. > 234°. The hydrochloride is the drug known as dilaudid. On 0-methyla-tion dihydromorphinone yields dihydrocodeinone (see above), and when dissolved in ether and treated with methyllithium the corresponding tertiary alcohol, 6-methyldihydromorphine, CigHggOgN, m.p. 209-211°, Wd ° 14i7° (EtOH), is formed. This on methylation with diazomethane gives 6-methyldihydrocodeine as described above (Small and Rapoport... 

In a continuation of the theme of simplification of the morphine ring, it was found that one of the carbocyclic rings (that which contained the allyl alcohol in morphine proper) can be dispensed with as well, to give compounds that show the full activity of the natural prototype. These agents, the benzomorphans, are of... 

There is a risk of acute renal failure when iodi-nated contrast material that is used for radiological studies is administered with metformin. Metformin therapy is stopped for 48 hours before and after radiological studies using iodinated material. Alcohol, amiloride, digoxin, morphine, procainamide, quini-dine, quinine ranitidine, triamterene, trimethoprim, vancomycin, cimetidine, and furosemide all increase the risk of hypoglycemia. There is an increased risk of lactic acidosis when metformin is administered with the glucocorticoids.

Per-O-acylated glycosyl iodides are stable at room temperature and can be purified on a silica gel column and stored at 0 °C. Stachulski and coworkers [202] synthesized methyl 2,3,4-tri-O-pivaloyl-glucopyranuroate iodide, which is a stable solid at 20 °C and can be stored for months at room temperature or for more than a year at 0 °C. The X-ray crystal structure of this compound, the first one of this class, shows a typical chair structure. Importantly, such a disarmed and stable iodide can be coupled with primary and secondary steroidal alcohols using I2 as a promoter, as demonstrated by the synthesis of morphine-6-glucuronide, an analgesic [202], The glycosyl donor ability... 

Some, but not all of ibogaine s effects may involve pharmacokinetic actions. Although ibogaine does not alter brain morphine or alcohol levels, it does alter amphetamine levels, suggesting a possible hepatic interaction (Click et al. 1992a Rezvani et al. 1995).
