[Pharmacokinetics of 1-(4'-oxyphenyl)-2-(3'-phenyl-thiopropyl-amino) propane-1-01 hydrochloride (Istiod) in the rat]. / Indagini farmacocinesiche sul 1-(4'-ossifenil)-2-(3'-feniltiopropil-amino)-propano-1-olo cloridrato (Isotiod) nel ratto.

The pharmacokinetics (serum, urinary and biliary concentrations) of Isotiod have been studied in rats. Doses exploited the property of the molecule in an alkaline medium with a diazonium salt to form coloured azo compounds. In rats Isotiod determines blood concentrations whose intensity and duration are proportional to the dose and route of administration; notable quantities of the drug are eliminated by the urinary way and a small quantity by the bile way with a personal technique.

Esters of 1,7,7-trimethyl-2-exo-piperidinobicyclo[2.2.1]heptan-3-endo-ol with antiarrhythmic, local anesthetic and other activities.

A series of aliphatic and aromatic esters of 1,7,7-trimethyl-2-exo-piperidinobicyclo[2.2.1]heptan-3-endo-ol is described. A number of these compounds showed antiarrhythmic activity in guinea pigs and mice, as well as surface anesthesia in rabbits and infiltration anesthesia in mice. Circulatory, cardiac and respiratory effects in dogs are also described.

Interactions between inosine and adenosine: experimental researches.

Experimental investigations have shown that inosine enhances purinergic reactivity. This was examined with adenosine at the level of the cardiovascular, intestinal and uterine musculature. The mechanism of this activity may probably be inhibition of uptake without significantly altering serum adenosinase.
