Validation of a UV spectrophotometric method for determining trans-dehydrocrotonin in inclusion complexes with hydroxypropyl-β-cyclodextrin
Trans-dehydrocrotonin (t-DCTN) is a 19-nor-clerodan diterpen with several important pharmacological properties, including hypoglycemic and antitumor activity. However the low water solubility and hepatotoxicity of t-DCTN limit its use in therapeutic applications. Drug inclusion complexes with cyclod...

description |
Trans-dehydrocrotonin (t-DCTN) is a 19-nor-clerodan diterpen with several important pharmacological properties, including hypoglycemic and antitumor activity. However the low water solubility and hepatotoxicity of t-DCTN limit its use in therapeutic applications. Drug inclusion complexes with cyclodextrins (CDs) can modify physicochemical properties of parent drugs, such as improving their aqueous solubility and reducing their toxicity. A UV method was therefore validated for determining t-DCTN in HP-β-CD inclusion complexes with a view to future applications in research and therapy. The regression equation of the analytical curve (1–20 μg/mL) was [t-DCTN] = absorbance + 0.00147/0.04214. The precision of the method was satisfactory, producing values of relative standard deviation less than 2 % for all samples analyzed. The accuracy was between 99.6 and 100.02 %. The content of t-DCTN in tDCTN:HP-β-CD was 99.8 %. The UV validated method developed is straightforward and suitable for use in the routine analysis of t-DCTN complexed with hydroxypropyl-β-cyclodextrin. |
