To develop more effective compounds as penetration enhancers, O-acylmenthol derivatives were synthesized by l-menthol and saturated fatty acid, O-ethylmenthot (MET), was also synthesized as a reference compound. Their promoting activity on the percutaneous absorption of five model drugs, 5-fluorouracil (5-FU), isosorbide dinitrate (ISDN), lidocaine (LD), ketoprofen (KP), indomethacin (IM), which were selected based on their lipophilicity represented by logK(O/W), was tested in vitro across full thickness rat skin with each of the evaluated drugs in saturated donor solution. Only 2-isopropyl-5-methylcyclohexyl tetradecanoate (C14 alkyl chain) had promoting effects on the percutaneous permeation of 5-FU; 2-isopropyl-5-methylcyclohexyl hexanoate (C6 alkyl chain), which increased the permeation coefficient (P) 1.91-fold, had the highest permeation for ISDN; in the case of LD, the highest increase in P was observed with 2-isopropyl-5-methylcyclohexyl heptanoate (C7 alkyl chain), which increased the P by 1.58-fold; MET, which increased the P by 2.02-fold, provided the best enhancement for KP; 2-isopropyl-5-methylcyclohexyl heptanoate (C7 alkyl chain) produced the highest increase in P, 3.70-fold for IM. These results suggest that some newly designed percutaneous absorption enhancers have the potential to enhance drugs with different lipophilicities. A chain length of C6-C10 seemed to be favorable for lipophilic drugs, while C14 was the most effective enhancer for hydrophilic drug (5-FU). (C) 2007 Elsevier B.V. All rights reserved.
