Journal ArticleDOI
Reversible association of caffeine and of some caffeine homologs in aqueous solution.
David Guttman,Takeru Higuchi +1 more
TL;DR: Experimental studies involving partitioning between two solvents suggest that caffeine undergoes rather marked association in aqueous solution, existing primarily as monomer, dimer, and tetramer, while 1-ethyltheobromine appears to exist in aQueous solution only in monomeric and dimeric forms.
Journal ArticleDOI
Prodrugs of 6-Thiopurines: Enhanced Delivery Through the Skin
TL;DR: The pivaloyloxymethyl derivatives showed the greatest potential for enhancing the penetration of the thiopurines through the skin, and VII and XI were the most effective; they delivered 5 and 13 times, respectively, more 6-mercaptopurine than 6-MERcaptopirine itself.
Journal ArticleDOI
Study of possible complex formation between macromolecules and certain pharmaceuticals. I. Polyvinylpyrrolidone with sulfathiazole, procaine hydrochloride, sodium salicylate, benzyl penicillin, chloramphenicol, mandelic acid, caffeine, theophylline, and cortisone.
Takeru Higuchi,Roy Kuramoto +1 more
TL;DR: Experimental data were obtained supporting the existence of complexes in solution with some pharmaceuticals such as sulfathiazole, sodium salicylate, chloramphenicol, and mandelic acid, and no evidence of complex formation was detected between polyvinylpyrrolidone and procaine hydrochloride.
Journal ArticleDOI
Physics of tablet compression. XV. Thermodynamic and kinetic aspects of adhesion under pressure.
Albert S. Rankell,Takeru Higuchi +1 more
TL;DR: A theoretical analysis has been made of the processes by which interparticle adhesion can occur during the compression of tablet granulations in the absence of added fluid adhesives, and the Clapeyron equation is modified to take into account the nonuniformity of the pressures exerted on the particles during compression.
Journal ArticleDOI
Study of Possible Complex Formation between Macromolecules and Certain Pharmaceuticals*: II. Polyvinylpyrrolidone with p-Aminobenzoic Acid, Aminopyrine, Benzoic Acid, Salicylic Acid, p-Hydroxybenzoic Acid, m-Hydroxybenzoic Acid, Citric Acid, and Phenobarbital
Takeru Higuchi,Roy Kuramoto +1 more
TL;DR: The similarity of the influence of chemical structure on the stability of the PVP complexes as compared to the caffeine complexes indicates that a similar mechanism may be responsible for both series.
