Effect of aminomethyl (N-Mannich base) derivatization on the ability of S6-acetyloxymethyl-6-mercaptopurine prodrug to deliver 6-mercaptopurine through hairless mouse skin
Saab,Sloan,Beall,Villanueva
, p. 1099 - 1104 (1990)
A series of 9-aminomethyl-S6-acetyloxymethyl-6-mercaptopurine (9-AM-6-AOM-6-MP) prodrugs have been synthesized and characterized, and their ability to deliver total 6-mercaptopurine (6-MP) through hairless mouse skin has been measured. The 9-AM-6-AOM-6-MP prodrugs are much more soluble in isopropyl myristate (IPM) than S6-acetyloxymethyl-6-MP (6-AOM-6-MP) itself or the corresponding 7-aminomethyl-6-MP (7-AM-6-MP) prodrugs. The 9-AM-6-AOM-6-MP prodrugs were all more effective (1.8-4 times) than 6-AOM-6-MP at delivering total 6-MP, except for the piperidylmethyl derivative which only gave a comparable rate of delivery. The 9-AM-6-AOM-6-MP prodrugs were also more effective (7-27 times) than the corresponding 7-AM-6-MP prodrugs at delivering 6-MP, except for the diethylaminomethyl derivative which only gave a comparable rate of delivery. In contrast to the 9-aminomethyl-S6-pivaloyloxymethyl-6-MP (9-AM-6-POM-6-MP) derivatives which generally delivered as much or more intact S6-pivaloyloxymethyl-6-MP (6-POM-6-MP) as 6-MP, the 9-AM-6-AOM-6-MP derivatives delivered mainly (80-95%) 6-MP from IPM. There was a direct correlation between log experimental permeability coefficients for delivery of total 6-MP (P(Σ)) and the calculated solubility parameter values for the 9-AM-6-AOM-6-MP prodrugs (δ(j)), with the P(Σ) generally decreasing as the value of δ(j) approached that of the vehicle, IPM. There was no significant effect of the prodrugs:IPM suspensions on the skin compared with 6-MP:IPM suspension or IPM, as determined by a second application of a standard solute:vehicle complex.

Reaction of alkylcarbonyloxymethyl halides with phenols: reevaluating the influence of steric hindrance
Thomas, Joshua D.,Sloan, Kenneth B.
, p. 8785 - 8787 (2007/10/03)
Evidence is presented that contradicts an earlier finding that, in the absence of steric hindrance, the coupling reaction of alkylcarbonyloxymethyl (ACOM) halides with phenols favors acylated product. A one-step synthesis is used to generate sterically unhindered ACOM iodides, which are then reacted with several phenols to give mainly alkylated phenol.
