Synthesis and characterization of binary and ternary complexes of diclofenac with a methyl-beta-CD and monoethanolamine and in vitro transdermal evaluation.

Abstract:

:Here, we describe the chemical characterization of the inclusion complex between diclofenac (DCF) and methyl-beta-cyclodextrin (M-beta-CD) in the presence or absence of monoethanolamine (MEA). Several techniques were used to analyze the complex both in solution and in the solid state. Solubility of DCF was increased by the addition of M-beta-CD. However, the DCF solubility increase was more significant by the addition of M-beta-CD in the presence of MEA. In vitro permeation experiments through excised human skin revealed that DCF was enhanced by M-beta-CD. Nevertheless, further improvement in the flux and the permeability coefficient of DCF was obtained by the ternary system DCF-M-beta-CD-MEA.

  • Selected C8 two-chain linkers enhance the adenosine A1/A2A receptor affinity and selectivity of caffeine.

    abstract::Recent research exploring C8 substitution on the caffeine core identified 8-(2-phenylethyl)-1,3,7-trimethylxanthine as a non-selective adenosine receptor antagonist. To elaborate further, we included various C8 two-chain-length linkers to enhance adenosine receptor affinity. The results indicated that the unsubstitute...
