10.1002/jps.2600570605.abs A new phenolic alkaloid was isolated from opium and named palaudine. It was characterized spectroscopically as 1‐(3′‐hydroxy‐4′‐methoxybenzyl)‐6,7‐dimethoxyisoquinoline and the structure confirmed by synthesis. The other three papaveroline trimethyl...
10.1002/jps.2600570623.abs Chromatographic investigation of alkaloid fractions from the leaves of Peumus boldus Molina revealed the presence of 17 alkaloidal components. Four of these were correlated with previously isolated aporphine constituents and two others were isolated and identified as...
10.1002/jps.2600570634.abs Treatment of 3‐amino‐4‐pyrazolecarboxamide with nitrous acid yielded 3‐diazo‐4‐pyrazolecarboxamide, which was cyclized to 4‐hydroxypyrazolo(3,4‐d)‐v‐triazine in aqueous solution. The latter is a structural analog of hypoxanthine as well as an aza...
10.1002/jps.2600570625.abs A strong correlation between ratios of drug metabolism by microsomal subfractions with 1‐octanol/water partition coefficient was found. Explanation for the spread of ratios is presented.
10.1002/jps.2600570611.abs Fully deuterated griseofulvin was isolated in pure form from P. janczewskii grown in a completely deuterated medium. Direct fermentation and a replacement culture technique were used. The isolated antibiotic was purified by thin‐layer chromatography and characterized...
10.1002/jps.2600570645.abs The synthesis of a new series of alkanolamine esters is described. Esterification of 1,1′‐iminodi‐2‐propanol with benzoyl chloride applying the Schotten‐Baumann conditions afforded either the mono or diester according to the molecular ratio of the reactants...
10.1002/jps.2600570633.abs Aspirin, like cortisone, reduces the tensile strength of the healing skin wound in rats. The possible mechanism of action of these anti‐inflammatory agents on wound healing has been discussed.
10.1002/jps.2600570616.abs Excellent correlation was obtained between assay values by the methanol‐sulfuric acid colorimetric method and a highly selective gas‐chromatographic procedure, the specificity of which was demonstrated by separations on two different columns. Quinestrol, ethinyl...
10.1002/jps.2600570630.abs Salvigenin was isolated from the air‐dried leaves and stems of S. triloba. Seventy percent aqueous ethanolic extract of the plant yields ursolic acid, oleonolic acid, β‐sitosterol, carnosol, and the above‐mentioned new flavone, when separated on a silicilic...
